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.

text: Although budding yeast has been extensively used as a model organism for studying
organelle functions and intracellular vesicle trafficking, whether it possesses
an independent endocytic early/sorting compartment that sorts endocytic cargos
to the endo-lysosomal pathway or the recycling pathway has long been unclear.
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.

text: Solute carriers are increasingly recognized as participating in a plethora
of pathologies, including cancer. 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.

text: Ribosomal defects perturb stem cell differentiation, causing diseases called
ribosomopathies. 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.

text: Cells migrate through crowded microenvironments within tissues during normal
development, immune response, and cancer metastasis. 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. This work
demonstrates that tissue dynamics can regulate cellular infiltration.

text: Cellular metabolism must adapt to changing demands to enable homeostasis.
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.

text: 'Endocytosis is a multistep process involving the sequential recruitment and
action of numerous proteins. 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.'

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. '

text: "The infiltration of immune cells into tissues underlies the establishment
of tissue-resident\r\nmacrophages and responses to infections and tumors. 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."

text: Optogenetics has been harnessed to shed new mechanistic light on current and
future therapeutic strategies. 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.
