--- _id: '14316' abstract: - lang: eng text: Clathrin-mediated vesicle trafficking plays central roles in post-Golgi transport. In yeast (Saccharomyces cerevisiae), the AP-1 complex and GGA adaptors are predicted to generate distinct transport vesicles at the trans-Golgi network (TGN), and the epsin-related proteins Ent3p and Ent5p (collectively Ent3p/5p) act as accessories for these adaptors. Recently, we showed that vesicle transport from the TGN is crucial for yeast Rab5 (Vps21p)-mediated endosome formation, and that Ent3p/5p are crucial for this process, whereas AP-1 and GGA adaptors are dispensable. However, these observations were incompatible with previous studies showing that these adaptors are required for Ent3p/5p recruitment to the TGN, and thus the overall mechanism responsible for regulation of Vps21p activity remains ambiguous. Here, we investigated the functional relationships between clathrin adaptors in post-Golgi-mediated Vps21p activation. We show that AP-1 disruption in the ent3Δ5Δ mutant impaired transport of the Vps21p guanine nucleotide exchange factor Vps9p transport to the Vps21p compartment and severely reduced Vps21p activity. Additionally, GGA adaptors, the phosphatidylinositol-4-kinase Pik1p and Rab11 GTPases Ypt31p and Ypt32p were found to have partially overlapping functions for recruitment of AP-1 and Ent3p/5p to the TGN. These findings suggest a distinct role of clathrin adaptors for Vps21p activation in the TGN–endosome trafficking pathway. article_number: jcs261448 article_processing_charge: No article_type: original author: - first_name: Makoto full_name: Nagano, Makoto last_name: Nagano - first_name: Kaito full_name: Aoshima, Kaito last_name: Aoshima - first_name: Hiroki full_name: Shimamura, Hiroki last_name: Shimamura - first_name: Daria E full_name: Siekhaus, Daria E id: 3D224B9E-F248-11E8-B48F-1D18A9856A87 last_name: Siekhaus orcid: 0000-0001-8323-8353 - first_name: Junko Y. full_name: Toshima, Junko Y. last_name: Toshima - first_name: Jiro full_name: Toshima, Jiro last_name: Toshima citation: ama: Nagano M, Aoshima K, Shimamura H, Siekhaus DE, Toshima JY, Toshima J.

The structure and properties of the endocytic early/sorting compartment differ significantly between organisms; in plant cells, the trans-Golgi network (TGN) serves this role, whereas in mammalian cells a separate intracellular structure performs this function. The yeast syntaxin homolog Tlg2p, widely localizing to the TGN and endosomal compartments, is presumed to act as a Q-SNARE for endocytic vesicles, but which compartment is the direct target for endocytic vesicles remained unanswered. Here we demonstrate by high-speed and high-resolution 4D imaging of fluorescently labeled endocytic cargos that the Tlg2p-residing compartment within the TGN functions as the early/sorting compartment. After arriving here, endocytic cargos are recycled to the plasma membrane or transported to the yeast Rab5-residing endosomal compartment through the pathway requiring the clathrin adaptors GGAs. Interestingly, Gga2p predominantly localizes at the Tlg2p-residing compartment, and the deletion of GGAs has little effect on another TGN region where Sec7p is present but suppresses dynamics of the Tlg2-residing early/sorting compartment, indicating that the Tlg2p- and Sec7p-residing regions are discrete entities in the mutant. Thus, the Tlg2p-residing region seems to serve as an early/sorting compartment and function independently of the Sec7p-residing region within the TGN. acknowledgement: 'This work was supported by JSPS KAKENHI grant #18K062291, and the Takeda Science Foundation to JYT., as well as JSPS KAKENHI grant #19K065710, the Takeda Science Foundation, and Life Science Foundation of Japan to JT.' article_number: e84850 article_processing_charge: Yes article_type: original author: - first_name: Junko Y. full_name: Toshima, Junko Y. last_name: Toshima - first_name: Ayana full_name: Tsukahara, Ayana last_name: Tsukahara - first_name: Makoto full_name: Nagano, Makoto last_name: Nagano - first_name: Takuro full_name: Tojima, Takuro last_name: Tojima - first_name: Daria E full_name: Siekhaus, Daria E id: 3D224B9E-F248-11E8-B48F-1D18A9856A87 last_name: Siekhaus orcid: 0000-0001-8323-8353 - first_name: Akihiko full_name: Nakano, Akihiko last_name: Nakano - first_name: Jiro full_name: Toshima, Jiro last_name: Toshima citation: ama: Toshima JY, Tsukahara A, Nagano M, et al.

We describe here the involvement of the orphan solute carrier MFSD1 in the regulation of tumor cell migration. Loss of MFSD1 enabled higher levels of metastasis in a mouse model. We identified an increased migratory potential in MFSD1-/- tumor cells which was mediated by increased focal adhesion turn-over, reduced stability of mature inactive β1 integrin, and the resulting increased integrin activation index. We show that MFSD1 promoted recycling to the cell surface of endocytosed inactive β1 integrin and thereby protected β1 integrin from proteolytic degradation; this led to dampening of the integrin activation index. Furthermore, down-regulation of MFSD1 expression was observed during early steps of tumorigenesis and higher MFSD1 expression levels correlate with a better cancer patient prognosis. In sum, we describe a requirement for endolysosomal MFSD1 in efficient β1 integrin recycling to suppress tumor spread. acknowledged_ssus: - _id: Bio acknowledgement: We thank M. Sixt, A.

How ribosome levels control stem cell differentiation is not fully known. Here, we discovered three RNA helicases are required for ribosome biogenesis and for Drosophila oogenesis. Loss of these helicases, which we named Aramis, Athos and Porthos, lead to aberrant stabilization of p53, cell cycle arrest and stalled GSC differentiation. Unexpectedly, Aramis is required for efficient translation of a cohort of mRNAs containing a 5’-Terminal-Oligo-Pyrimidine (TOP)-motif, including mRNAs that encode ribosomal proteins and a conserved p53 inhibitor, Novel Nucleolar protein 1 (Non1). The TOP-motif co-regulates the translation of growth-related mRNAs in mammals. As in mammals, the La-related protein co-regulates the translation of TOP-motif containing RNAs during Drosophila oogenesis. Thus, a previously unappreciated TOP-motif in Drosophila responds to reduced ribosome biogenesis to co-regulate the translation of ribosomal proteins and a p53 repressor, thus coupling ribosome biogenesis to GSC differentiation. acknowledgement: We are grateful to all members of the Rangan and Fuchs labs for their discussion and comments on the manuscript.

Although migration through pores and tracks in the extracellular matrix (ECM) has been well studied, little is known about cellular traversal into confining cell-dense tissues. We find that embryonic tissue invasion by Drosophila macrophages requires division of an epithelial ectodermal cell at the site of entry. Dividing ectodermal cells disassemble ECM attachment formed by integrin-mediated focal adhesions next to mesodermal cells, allowing macrophages to move their nuclei ahead and invade between two immediately adjacent tissues. Invasion efficiency depends on division frequency, but reduction of adhesion strength allows macrophage entry independently of division.

During immune responses or cancer metastasis, cells leading migration into challenging environments require an energy boost, but what controls this capacity is unclear. Here, we study a previously uncharacterized nuclear protein, Atossa (encoded by CG9005), which supports macrophage invasion into the germband of Drosophila by controlling cellular metabolism. First, nuclear Atossa increases mRNA levels of Porthos, a DEAD-box protein, and of two metabolic enzymes, lysine-α-ketoglutarate reductase (LKR/SDH) and NADPH glyoxylate reductase (GR/HPR), thus enhancing mitochondrial bioenergetics. Then Porthos supports ribosome assembly and thereby raises the translational efficiency of a subset of mRNAs, including those affecting mitochondrial functions, the electron transport chain, and metabolism. Mitochondrial respiration measurements, metabolomics, and live imaging indicate that Atossa and Porthos power up OxPhos and energy production to promote the forging of a path into tissues by leading macrophages. Since many crucial physiological responses require increases in mitochondrial energy output, this previously undescribed genetic program may modulate a wide range of cellular behaviors. acknowledged_ssus: - _id: Bio acknowledgement: "We thank the DGRC (NIH grant 2P40OD010949-10A1) for plasmids, the BDSC (NIH grant P40OD018537) and the VDRC for fly stocks, FlyBase for essential genomic information, the BDGP in situ database for data (Tomancak et al, 2007), the IST Austria Bioimaging facility for support, the VBC Core Facilities for RNA sequencing and analysis, and C.

This process can be divided into two phases: an early phase, in which sites of endocytosis are formed, and a late phase in which clathrin-coated vesicles are formed and internalized into the cytosol, but how these phases link to each other remains unclear. In this study, we demonstrate that anchoring the yeast Eps15-like protein Pan1p to the peroxisome triggers most of the events occurring during the late phase at the peroxisome. At this ectopic location, Pan1p recruits most proteins that function in the late phases—including actin nucleation promoting factors—and then initiates actin polymerization. Pan1p also recruited Prk1 kinase and actin depolymerizing factors, thereby triggering disassembly immediately after actin assembly and inducing dissociation of endocytic proteins from the peroxisome. These observations suggest that Pan1p is a key regulator for initiating, processing, and completing the late phase of endocytosis.' acknowledgement: 'This work was supported by JSPS KAKENHI GRANT #18K062291, and the Takeda Science Foundation to J.Y.

Yet the mechanisms immune cells utilize to negotiate tissue barriers in living organisms are not well understood, and a role for cortical actin has not been examined. Here, we find that the tissue invasion of Drosophila macrophages, also known as plasmatocytes or hemocytes, utilizes enhanced cortical F-actin levels stimulated by the Drosophila member of the fos proto oncogene transcription factor family (Dfos, Kayak). RNA sequencing analysis and live imaging show that Dfos enhances F-actin levels around the entire macrophage surface by increasing mRNA levels of the membrane spanning molecular scaffold tetraspanin TM4SF, and the actin cross-linking filamin Cheerio, which are themselves required for invasion. Both the filamin and the tetraspanin enhance the cortical activity of Rho1 and the formin Diaphanous and thus the assembly of cortical actin, which is a critical function since expressing a dominant active form of Diaphanous can rescue the Dfos macrophage invasion defect. In vivo imaging shows that Dfos enhances the efficiency of the initial phases of macrophage tissue entry. Genetic evidence argues that this Dfos-induced program in macrophages counteracts the constraint produced by the tension of surrounding tissues and buffers the properties of the macrophage nucleus from affecting tissue entry. We thus identify strengthening the cortical actin cytoskeleton through Dfos as a key process allowing efficient forward movement of an immune cell into surrounding tissues.

However, the mechanisms immune\r\ncells utilize to collectively migrate through tissue barriers in vivo are not yet well understood.\r\nIn this thesis, I describe two mechanisms that Drosophila immune cells (hemocytes) use to\r\novercome the tissue barrier of the germband in the embryo. One strategy is the strengthening\r\nof the actin cortex through developmentally controlled transcriptional regulation induced by\r\nthe Drosophila proto-oncogene family member Dfos, which I show in Chapter 2. Dfos induces\r\nexpression of the tetraspanin TM4SF and the filamin Cher leading to higher levels of the\r\nactivated formin Dia at the cortex and increased cortical F-actin. This enhanced cortical\r\nstrength allows hemocytes to overcome the physical resistance of the surrounding tissue and\r\ntranslocate their nucleus to move forward. This mechanism affects the speed of migration\r\nwhen hemocytes face a confined environment in vivo.\r\nAnother aspect of the invasion process is the initial step of the leading hemocytes entering\r\nthe tissue, which potentially guides the follower cells. In Chapter 3, I describe a novel\r\nsubpopulation of hemocytes activated by BMP signaling prior to tissue invasion that leads\r\npenetration into the germband. Hemocytes that are deficient in BMP signaling activation\r\nshow impaired persistence at the tissue entry, while their migration speed remains\r\nunaffected.\r\nThis suggests that there might be different mechanisms controlling immune cell migration\r\nwithin the confined environment in vivo, one of these being the general ability to overcome\r\nthe resistance of the surrounding tissue and another affecting the order of hemocytes that\r\ncollectively invade the tissue in a stream of individual cells.\r\nTogether, my findings provide deeper insights into transcriptional changes in immune\r\ncells that enable efficient tissue invasion and pave the way for future studies investigating the\r\nearly colonization of tissues by macrophages in higher organisms. Moreover, they extend the\r\ncurrent view of Drosophila immune cell heterogeneity and point toward a potentially\r\nconserved role for canonical BMP signaling in specifying immune cells that lead the migration\r\nof tissue resident macrophages during embryogenesis." acknowledged_ssus: - _id: LifeSc alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Stephanie full_name: Wachner, Stephanie id: 2A95E7B0-F248-11E8-B48F-1D18A9856A87 last_name: Wachner citation: ama: Wachner S.

This has been to date achieved by the regulation of ion flow and electrical signals in neuronal cells and neural circuits that are known to be affected by disease. In contrast, the optogenetic delivery of trophic biochemical signals, which support cell survival and are implicated in degenerative disorders, has never been demonstrated in an animal model of disease. Here, we reengineered the human and Drosophila melanogaster REarranged during Transfection (hRET and dRET) receptors to be activated by light, creating one-component optogenetic tools termed Opto-hRET and Opto-dRET. Upon blue light stimulation, these receptors robustly induced the MAPK/ERK proliferative signaling pathway in cultured cells. In PINK1B9 flies that exhibit loss of PTEN-induced putative kinase 1 (PINK1), a kinase associated with familial Parkinson’s disease (PD), light activation of Opto-dRET suppressed mitochondrial defects, tissue degeneration and behavioral deficits. In human cells with PINK1 loss-of-function, mitochondrial fragmentation was rescued using Opto-dRET via the PI3K/NF-кB pathway. Our results demonstrate that a light-activated receptor can ameliorate disease hallmarks in a genetic model of PD. The optogenetic delivery of trophic signals is cell type-specific and reversible and thus has the potential to inspire novel strategies towards a spatio-temporal regulation of tissue repair. acknowledgement: We thank R.

Cancer progression is often associated with an enhanced recruitment of myeloid-derived cells to the tumor microenvironment. Here we show that functional TGFβ-signaling in myeloid cells is required for metastasis to the lungs and the liver. Myeloid-specific deletion of Tgfbr2 resulted in reduced spontaneous lung metastasis, which was associated with a reduction of proinflammatory cytokines in the metastatic microenvironment. Notably, CD8+ T cell depletion in myeloid-specific Tgfbr2-deficient mice rescued lung metastasis. Myeloid-specific Tgfbr2-deficiency resulted in reduced liver metastasis with an almost complete absence of myeloid cells within metastatic foci. On contrary, an accumulation of Tgfβ-responsive myeloid cells was associated with an increased recruitment of monocytes and granulocytes and higher proinflammatory cytokine levels in control mice. Monocytic cells isolated from metastatic livers of Tgfbr2-deficient mice showed increased polarization towards the M1 phenotype, Tnfα and Il-1β expression, reduced levels of M2 markers and reduced production of chemokines responsible for myeloid-cell recruitment. No significant differences in Tgfβ levels were observed at metastatic sites of any model. These data demonstrate that Tgfβ signaling in monocytic myeloid cells suppresses CD8+ T cell activity during lung metastasis, while these cells actively contribute to tumor growth during liver metastasis. Thus, myeloid cells modulate metastasis through different mechanisms in a tissue-specific manner. acknowledgement: The authors acknowledge the assistance of the Laboratory Animal Services Center (LASC) – UZH, Center for Microscopy and Image Analysis, and the Flow Cytometry Center of the University of Zurich. article_number: '765151' article_processing_charge: No article_type: original author: - first_name: Cristina full_name: Stefanescu, Cristina last_name: Stefanescu - first_name: Merel full_name: Van Gogh, Merel last_name: Van Gogh - first_name: Marko full_name: Roblek, Marko id: 3047D808-F248-11E8-B48F-1D18A9856A87 last_name: Roblek orcid: 0000-0001-9588-1389 - first_name: Mathias full_name: Heikenwalder, Mathias last_name: Heikenwalder - first_name: Lubor full_name: Borsig, Lubor last_name: Borsig citation: ama: Stefanescu C, Van Gogh M, Roblek M, Heikenwalder M, Borsig L.

Like many mammalian cytokines, unpaireds can be activated by infection and other stresses and can promote insulin resistance in target tissues. However, the importance of this effect in non-inflammatory physiology is unknown. Here, we identify a requirement for unpaired-JAK signalling as a metabolic regulator in healthy adult Drosophila muscle. Adult muscles show basal JAK-STAT signalling activity in the absence of any immune challenge. Plasmatocytes (Drosophila macrophages) are an important source of this tonic signal. Loss of the dome receptor on adult muscles significantly reduces lifespan and causes local and systemic metabolic pathology. These pathologies result from hyperactivation of AKT and consequent deregulation of metabolism. Thus, we identify a cytokine signal that must be received in muscle to control AKT activity and metabolic homeostasis. article_number: e51595 article_processing_charge: No article_type: original author: - first_name: Katrin full_name: Kierdorf, Katrin last_name: Kierdorf - first_name: Fabian full_name: Hersperger, Fabian last_name: Hersperger - first_name: Jessica full_name: Sharrock, Jessica last_name: Sharrock - first_name: Crystal M. full_name: Vincent, Crystal M. last_name: Vincent - first_name: Pinar full_name: Ustaoglu, Pinar last_name: Ustaoglu - first_name: Jiawen full_name: Dou, Jiawen last_name: Dou - first_name: Attila full_name: György, Attila id: 3BCEDBE0-F248-11E8-B48F-1D18A9856A87 last_name: György orcid: 0000-0002-1819-198X - first_name: Olaf full_name: Groß, Olaf last_name: Groß - first_name: Daria E full_name: Siekhaus, Daria E id: 3D224B9E-F248-11E8-B48F-1D18A9856A87 last_name: Siekhaus orcid: 0000-0001-8323-8353 - first_name: Marc S. full_name: Dionne, Marc S. last_name: Dionne citation: ama: Kierdorf K, Hersperger F, Sharrock J, et al.

It tunes the metabolic programs of migrating cells to allow them to efficiently exert their crucial roles in development, inflammatory responses and tumor metastasis. Cell migration through physically challenging contexts requires energy. However, how the metabolic reprogramming that underlies in vivo cell invasion is controlled is still unanswered. In my PhD project, I identify a novel conserved metabolic shift in Drosophila melanogaster immune cells that by modulating their bioenergetic potential controls developmentally programmed tissue invasion. We show that this regulation requires a novel conserved nuclear protein, named Atossa. Atossa enhances the transcription of a set of proteins, including an RNA helicase Porthos and two metabolic enzymes, each of which increases the tissue invasion of leading Drosophila macrophages and can rescue the atossa mutant phenotype. Porthos selectively regulates the translational efficiency of a subset of mRNAs containing a 5’-UTR cis-regulatory TOP-like sequence. These 5’TOPL mRNA targets encode mitochondrial-related proteins, including subunits of mitochondrial oxidative phosphorylation (OXPHOS) components III and V and other metabolic-related proteins. Porthos powers up mitochondrial OXPHOS to engender a sufficient ATP supply, which is required for tissue invasion of leading macrophages. Atossa’s two vertebrate orthologs rescue the invasion defect. In my PhD project, I elucidate that Atossa displays a conserved developmental metabolic control to modulate metabolic capacities and the cellular energy state, through altered transcription and translation, to aid the tissue infiltration of leading cells into energy demanding barriers. acknowledged_ssus: - _id: Bio - _id: LifeSc - _id: E-Lib - _id: CampIT acknowledgement: Also, I would like to express my appreciation and thanks to the Bioimaging facility, LSF, GSO, library, and IT people at IST Austria. alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Shamsi full_name: Emtenani, Shamsi id: 49D32318-F248-11E8-B48F-1D18A9856A87 last_name: Emtenani orcid: 0000-0001-6981-6938 citation: ama: Emtenani S.

Yet the mechanisms immune cells utilize to negotiate tissue barriers in living organisms are not well understood, and a role for cortical actin has not been examined. Here we find that the tissue invasion of Drosophila macrophages, also known as plasmatocytes or hemocytes, utilizes enhanced cortical F-actin levels stimulated by the Drosophila member of the fos proto oncogene transcription factor family (Dfos, Kayak). RNA sequencing analysis and live imaging show that Dfos enhances F-actin levels around the entire macrophage surface by increasing mRNA levels of the membrane spanning molecular scaffold tetraspanin TM4SF, and the actin cross-linking filamin Cheerio which are themselves required for invasion. Cortical F-actin levels are critical as expressing a dominant active form of Diaphanous, a actin polymerizing Formin, can rescue the Dfos Dominant Negative macrophage invasion defect. In vivo imaging shows that Dfos is required to enhance the efficiency of the initial phases of macrophage tissue entry. Genetic evidence argues that this Dfos-induced program in macrophages counteracts the constraint produced by the tension of surrounding tissues and buffers the mechanical properties of the macrophage nucleus from affecting tissue entry. We thus identify tuning the cortical actin cytoskeleton through Dfos as a key process allowing efficient forward movement of an immune cell into surrounding tissues. acknowledged_ssus: - _id: LifeSc acknowledgement: 'We thank the following for their contributions: The Drosophila Genomics Resource Center supported by NIH grant 2P40OD010949-10A1 for plasmids, K.

Experimental evidence suggests that CCL2 correlates with inflammatory monocyte recruitment and induction of vascular activation, but the functionality remains open. Here, we show that endothelial Ccr2 facilitates pulmonary metastasis using an endothelial-specific Ccr2-deficient mouse model (Ccr2ecKO). Similar levels of circulating monocytes and equal leukocyte recruitment to metastatic lesions of Ccr2ecKO and Ccr2fl/fl littermates were observed. The absence of endothelial Ccr2 strongly reduced pulmonary metastasis, while the primary tumor growth was unaffected. Despite a comparable cytokine milieu in Ccr2ecKO and Ccr2fl/fl littermates the absence of vascular permeability induction was observed only in Ccr2ecKO mice. CCL2 stimulation of pulmonary endothelial cells resulted in increased phosphorylation of MLC2, endothelial cell retraction, and vascular leakiness that was blocked by an addition of a CCR2 inhibitor. These data demonstrate that endothelial CCR2 expression is required for tumor cell extravasation and pulmonary metastasis.\r\n\r\nImplications: The findings provide mechanistic insight into how CCL2–CCR2 signaling in endothelial cells promotes their activation through myosin light chain phosphorylation, resulting in endothelial retraction and enhanced tumor cell migration and metastasis." article_processing_charge: No article_type: original author: - first_name: Marko full_name: Roblek, Marko id: 3047D808-F248-11E8-B48F-1D18A9856A87 last_name: Roblek orcid: 0000-0001-9588-1389 - first_name: Darya full_name: Protsyuk, Darya last_name: Protsyuk - first_name: Paul F. full_name: Becker, Paul F. last_name: Becker - first_name: Cristina full_name: Stefanescu, Cristina last_name: Stefanescu - first_name: Christian full_name: Gorzelanny, Christian last_name: Gorzelanny - first_name: Jesus F. full_name: Glaus Garzon, Jesus F. last_name: Glaus Garzon - first_name: Lucia full_name: Knopfova, Lucia last_name: Knopfova - first_name: Mathias full_name: Heikenwalder, Mathias last_name: Heikenwalder - first_name: Bruno full_name: Luckow, Bruno last_name: Luckow - first_name: Stefan W. full_name: Schneider, Stefan W. last_name: Schneider - first_name: Lubor full_name: Borsig, Lubor last_name: Borsig citation: ama: Roblek M, Protsyuk D, Becker PF, et al.

Thus, early endosome existence isthought to be maintained by the continual fusion of transport vesicles from the plasmamembrane and thetrans-Golgi network (TGN). Here we show instead that endocytosis isdispensable and post-Golgi vesicle transport is crucial for the formation of endosomes andthe subsequent endolysosomal traffic regulated by yeast Rab5 Vps21p. Fittingly, all threeproteins required for endosomal nucleotide exchange on Vps21p arefirst recruited to theTGN before transport to the endosome, namely the GEF Vps9p and the epsin-relatedadaptors Ent3/5p. The TGN recruitment of these components is distinctly controlled, withVps9p appearing to require the Arf1p GTPase, and the Rab11s, Ypt31p/32p. These resultsprovide a different view of endosome formation and identify the TGN as a critical location forregulating progress through the endolysosomal trafficking pathway. article_number: '419' article_processing_charge: No article_type: original author: - first_name: Makoto full_name: Nagano, Makoto last_name: Nagano - first_name: Junko Y. full_name: Toshima, Junko Y. last_name: Toshima - first_name: Daria E full_name: Siekhaus, Daria E id: 3D224B9E-F248-11E8-B48F-1D18A9856A87 last_name: Siekhaus orcid: 0000-0001-8323-8353 - first_name: Jiro full_name: Toshima, Jiro last_name: Toshima citation: ama: Nagano M, Toshima JY, Siekhaus DE, Toshima J.

Variation in hormone transport, which depends on a delicate interplay between PIN2 sorting to and from polar plasma membrane domains, determines root growth. By employing a constitutively degraded version of PIN2, we identify brassinolides as antagonists of PIN2 endocytosis. This response does not require de novo protein synthesis, but involves early events in canonical brassinolide signaling. Brassinolide-controlled adjustments in PIN2 sorting and intracellular distribution governs formation of a lateral PIN2 gradient in gravistimulated roots, coinciding with adjustments in auxin signaling and directional root growth. Strikingly, simulations indicate that PIN2 gradient formation is no prerequisite for root bending but rather dampens asymmetric auxin flow and signaling. Crosstalk between brassinolide signaling and endocytic PIN2 sorting, thus, appears essential for determining the rate of gravity-induced root curvature via attenuation of differential cell elongation. article_number: '5516' article_processing_charge: No article_type: original author: - first_name: Katarzyna full_name: Retzer, Katarzyna last_name: Retzer - first_name: Maria full_name: Akhmanova, Maria id: 3425EC26-F248-11E8-B48F-1D18A9856A87 last_name: Akhmanova orcid: 0000-0003-1522-3162 - first_name: Nataliia full_name: Konstantinova, Nataliia last_name: Konstantinova - first_name: Kateřina full_name: Malínská, Kateřina last_name: Malínská - first_name: Johannes full_name: Leitner, Johannes last_name: Leitner - first_name: Jan full_name: Petrášek, Jan last_name: Petrášek - first_name: Christian full_name: Luschnig, Christian last_name: Luschnig citation: ama: Retzer K, Akhmanova M, Konstantinova N, et al.

Drosophila hemocytes patrol the body cavity and act as macrophages outside the nervous system whereas glia originate from the neuroepithelium and provide the scavenger population of the nervous system. Drosophila glia are hence the functional orthologs of vertebrate microglia, even though the latter are cells of immune origin that subsequently move into the brain during development. Interestingly, the Drosophila immune cells within (glia) and outside the nervous system (hemocytes) require the same transcription factor Glide/Gcm for their development. This raises the issue of how do glia specifically differentiate in the nervous system and hemocytes in the procephalic mesoderm. The Repo homeodomain transcription factor and pan-glial direct target of Glide/Gcm is known to ensure glial terminal differentiation. Here we show that Repo also takes center stage in the process that discriminates between glia and hemocytes. First, Repo expression is repressed in the hemocyte anlagen by mesoderm-specific factors. Second, Repo ectopic activation in the procephalic mesoderm is sufficient to repress the expression of hemocyte-specific genes. Third, the lack of Repo triggers the expression of hemocyte markers in glia. Thus, a complex network of tissue-specific cues biases the potential of Glide/Gcm. These data allow us to revise the concept of fate determinants and help us understand the bases of cell specification. Both sexes were analyzed.SIGNIFICANCE STATEMENTDistinct cell types often require the same pioneer transcription factor, raising the issue of how does one factor trigger different fates. In Drosophila, glia and hemocytes provide a scavenger activity within and outside the nervous system, respectively. While they both require the Glide/Gcm transcription factor, glia originate from the ectoderm, hemocytes from the mesoderm. Here we show that tissue-specific factors inhibit the gliogenic potential of Glide/Gcm in the mesoderm by repressing the expression of the homeodomain protein Repo, a major glial-specific target of Glide/Gcm. Repo expression in turn inhibits the expression of hemocyte-specific genes in the nervous system. These cell-specific networks secure the establishment of the glial fate only in the nervous system and allow cell diversification. acknowledgement: This work was supported by INSERM, CNRS, UDS, Ligue Régionale contre le Cancer, Hôpital de Strasbourg, Association pour la Recherche sur le Cancer (ARC) and Agence Nationale de la Recherche (ANR) grants.

Here we show that T-antigen in Drosophila melanogaster macrophages is involved in their developmentally programmed tissue invasion. Higher macrophage T-antigen levels require an atypical major facilitator superfamily (MFS) member that we named Minerva which enables macrophage dissemination and invasion. We characterize for the first time the T and Tn glycoform O-glycoproteome of the Drosophila melanogaster embryo, and determine that Minerva increases the presence of T-antigen on proteins in pathways previously linked to cancer, most strongly on the sulfhydryl oxidase Qsox1 which we show is required for macrophage tissue entry. Minerva’s vertebrate ortholog, MFSD1, rescues the minerva mutant’s migration and T-antigen glycosylation defects. We thus identify a key conserved regulator that orchestrates O-glycosylation on a protein subset to activate a program governing migration steps important for both development and cancer metastasis. acknowledged_ssus: - _id: LifeSc article_number: e41801 article_processing_charge: No author: - first_name: Katarina full_name: Valosková, Katarina id: 46F146FC-F248-11E8-B48F-1D18A9856A87 last_name: Valosková - first_name: Julia full_name: Biebl, Julia id: 3CCBB46E-F248-11E8-B48F-1D18A9856A87 last_name: Biebl - first_name: Marko full_name: Roblek, Marko id: 3047D808-F248-11E8-B48F-1D18A9856A87 last_name: Roblek orcid: 0000-0001-9588-1389 - first_name: Shamsi full_name: Emtenani, Shamsi id: 49D32318-F248-11E8-B48F-1D18A9856A87 last_name: Emtenani orcid: 0000-0001-6981-6938 - first_name: Attila full_name: György, Attila id: 3BCEDBE0-F248-11E8-B48F-1D18A9856A87 last_name: György orcid: 0000-0002-1819-198X - first_name: Michaela full_name: Misova, Michaela id: 495A3C32-F248-11E8-B48F-1D18A9856A87 last_name: Misova orcid: 0000-0003-2427-6856 - first_name: Aparna full_name: Ratheesh, Aparna id: 2F064CFE-F248-11E8-B48F-1D18A9856A87 last_name: Ratheesh orcid: 0000-0001-7190-0776 - first_name: Patricia full_name: Rodrigues, Patricia id: 2CE4065A-F248-11E8-B48F-1D18A9856A87 last_name: Rodrigues - first_name: Katerina full_name: Shkarina, Katerina last_name: Shkarina - first_name: Ida Signe Bohse full_name: Larsen, Ida Signe Bohse last_name: Larsen - first_name: Sergey Y full_name: Vakhrushev, Sergey Y last_name: Vakhrushev - first_name: Henrik full_name: Clausen, Henrik last_name: Clausen - first_name: Daria E full_name: Siekhaus, Daria E id: 3D224B9E-F248-11E8-B48F-1D18A9856A87 last_name: Siekhaus orcid: 0000-0001-8323-8353 citation: ama: Valosková K, Bicher J, Roblek M, et al.
