text: Glycoinositolphosphoceramides (GIPCs) are complex sphingolipids present at
the plasma membrane of various eukaryotes with the important exception of mammals.
In fungi, these glycosphingolipids commonly contain an alpha-mannose residue (Man)
linked at position 2 of the inositol. However, several pathogenic fungi additionally
synthesize zwitterionic GIPCs carrying an alpha-glucosamine residue (GlcN) at
this position. In the human pathogen Aspergillus fumigatus, the GlcNalpha1,2IPC
core (where IPC is inositolphosphoceramide) is elongated to Manalpha1,3Manalpha1,6GlcNalpha1,2IPC,
which is the most abundant GIPC synthesized by this fungus. In this study, we
identified an A. fumigatus N-acetylglucosaminyltransferase, named GntA, and demonstrate
its involvement in the initiation of zwitterionic GIPC biosynthesis. Targeted
deletion of the gene encoding GntA in A. fumigatus resulted in complete absence
of zwitterionic GIPC; a phenotype that could be reverted by episomal expression
of GntA in the mutant. The N-acetylhexosaminyltransferase activity of GntA was
substantiated by production of N-acetylhexosamine-IPC in the yeast Saccharomyces
cerevisiae upon GntA expression. Using an in vitro assay, GntA was furthermore
shown to use UDP-N-acetylglucosamine as donor substrate to generate a glycolipid
product resistant to saponification and to digestion by phosphatidylinositol-phospholipase
C as expected for GlcNAcalpha1,2IPC. Finally, as the enzymes involved in mannosylation
of IPC, GntA was localized to the Golgi apparatus, the site of IPC synthesis.

text: Deposits of misfolded proteins in the human brain are associated with the
development of many neurodegenerative diseases. Recent studies show that these
proteins have common traits even at the monomer level. Among them, a polyglutamine
region that is present in huntingtin is known to exhibit a correlation between
the length of the chain and the severity as well as the earliness of the onset
of Huntington disease. Here, we apply bias exchange molecular dynamics to generate
structures of polyglutamine expansions of several lengths and characterize the
resulting independent conformations. We compare the properties of these conformations
to those of the standard proteins, as well as to other homopolymeric tracts. We
find that, similar to the previously studied polyvaline chains, the set of possible
transient folds is much broader than the set of known-to-date folds, although
the conformations have different structures. We show that the mechanical stability
is not related to any simple geometrical characteristics of the structures. We
demonstrate that long polyglutamine expansions result in higher mechanical stability
than the shorter ones. They also have a longer life span and are substantially
more prone to form knotted structures. The knotted region has an average length
of 35 residues, similar to the typical threshold for most polyglutamine-related
diseases. Similarly, changes in shape and mechanical stability appear once the
total length of the peptide exceeds this threshold of 35 glutamine residues. We
suggest that knotted conformers may also harm the cellular machinery and thus
lead to disease.

text: 3D amoeboid cell migration is central to many developmental and disease-related
processes such as cancer metastasis. Here, we identify a unique prototypic amoeboid
cell migration mode in early zebrafish embryos, termed stable-bleb migration.
Stable-bleb cells display an invariant polarized balloon-like shape with exceptional
migration speed and persistence. Progenitor cells can be reversibly transformed
into stable-bleb cells irrespective of their primary fate and motile characteristics
by increasing myosin II activity through biochemical or mechanical stimuli. Using
a combination of theory and experiments, we show that, in stable-bleb cells, cortical
contractility fluctuations trigger a stochastic switch into amoeboid motility,
and a positive feedback between cortical flows and gradients in contractility
maintains stable-bleb cell polarization. We further show that rearward cortical
flows drive stable-bleb cell migration in various adhesive and non-adhesive environments,
unraveling a highly versatile amoeboid migration phenotype.

text: In the last several decades, developmental biology has clarified the molecular
mechanisms of embryogenesis and organogenesis. In particular, it has demonstrated
that the “tool-kit genes” essential for regulating developmental processes are
not only highly conserved among species, but are also used as systems at various
times and places in an organism to control distinct developmental events. Therefore,
mutations in many of these tool-kit genes may cause congenital diseases involving
morphological abnormalities. This link between genes and abnormal morphological
phenotypes underscores the importance of understanding how cells behave and contribute
to morphogenesis as a result of gene function. Recent improvements in live imaging
and in quantitative analyses of cellular dynamics will advance our understanding
of the cellular pathogenesis of congenital diseases associated with aberrant morphologies.
In these studies, it is critical to select an appropriate model organism for the
particular phenomenon of interest.

text: We provide theoretical tests of a novel experimental technique to determine
mechanostability of proteins based on stretching a mechanically protected protein
by single-molecule force spectroscopy. This technique involves stretching a homogeneous
or heterogeneous chain of reference proteins (single-molecule markers) in which
one of them acts as host to the guest protein under study. The guest protein is
grafted into the host through genetic engineering. It is expected that unraveling
of the host precedes the unraveling of the guest removing ambiguities in the reading
of the force-extension patterns of the guest protein. We study examples of such
systems within a coarse-grained structure-based model. We consider systems with
various ratios of mechanostability for the host and guest molecules and compare
them to experimental results involving cohesin I as the guest molecule. For a
comparison, we also study the force-displacement patterns in proteins that are
linked in a serial fashion. We find that the mechanostability of the guest is
similar to that of the isolated or serially linked protein. We also demonstrate
that the ideal configuration of this strategy would be one in which the host is
much more mechanostable than the single-molecule markers. We finally show that
it is troublesome to use the highly stable cystine knot proteins as a host to
graft a guest in stretching studies because this would involve a cleaving procedure.

text: Epithelial cell layers need to be tightly regulated to maintain their integrity
and correct function. Cell integration into epithelial sheets is now shown to
depend on the N-WASP-regulated stabilization of cortical F-actin, which generates
distinct patterns of apical-lateral contractility at E-cadherin-based cell-cell
junctions.

text: In the past decade carbon nanotubes (CNTs) have been widely studied as a potential
drug-delivery system, especially with functionality for cellular targeting. Yet,
little is known about the actual process of docking to cell receptors and transport
dynamics after internalization. Here we performed single-particle studies of folic
acid (FA) mediated CNT binding to human carcinoma cells and their transport inside
the cytosol. In particular, we employed molecular recognition force spectroscopy,
an atomic force microscopy based method, to visualize and quantify docking of
FA functionalized CNTs to FA binding receptors in terms of binding probability
and binding force. We then traced individual fluorescently labeled, FA functionalized
CNTs after specific uptake, and created a dynamic 'roadmap' that clearly showed
trajectories of directed diffusion and areas of nanotube confinement in the cytosol.
Our results demonstrate the potential of a single-molecule approach for investigation
of drug-delivery vehicles and their targeting capacity.

text: We derive the equations for a thin, axisymmetric elastic shell subjected to
an internal active stress giving rise to active tension and moments within the
shell. We discuss the stability of a cylindrical elastic shell and its response
to a localized change in internal active stress. This description is relevant
to describe the cellular actomyosin cortex, a thin shell at the cell surface behaving
elastically at a short timescale and subjected to active internal forces arising
from myosin molecular motor activity. We show that the recent observations of
cell deformation following detachment of adherent cells (Maître J-L et al 2012
Science 338 253-6) are well accounted for by this mechanical description. The
actin cortex elastic and bending moduli can be obtained from a quantitative analysis
of cell shapes observed in these experiments. Our approach thus provides a non-invasive,
imaging-based method for the extraction of cellular physical parameters.

text: 'Avian forelimb digit homology remains one of the standard themes in comparative
biology and EvoDevo research. In order to resolve the apparent contradictions
between embryological and paleontological evidence a variety of hypotheses have
been presented in recent years. The proposals range from excluding birds from
the dinosaur clade, to assignments of homology by different criteria, or even
assuming a hexadactyl tetrapod limb ground state. At present two approaches prevail:
the frame shift hypothesis and the pyramid reduction hypothesis. While the former
postulates a homeotic shift of digit identities, the latter argues for a gradual
bilateral reduction of phalanges and digits. Here we present a new model that
integrates elements from both hypotheses with the existing experimental and fossil
evidence. We start from the main feature common to both earlier concepts, the
initiating ontogenetic event: reduction and loss of the anterior-most digit. It
is proposed that a concerted mechanism of molecular regulation and developmental
mechanics is capable of shifting the boundaries of hoxD expression in embryonic
forelimb buds as well as changing the digit phenotypes. Based on a distinction
between positional (topological) and compositional (phenotypic) homology criteria,
we argue that the identity of the avian digits is II, III, IV, despite a partially
altered phenotype. Finally, we introduce an alternative digit reduction scheme
that reconciles the current fossil evidence with the presented molecular-morphogenetic
model. Our approach identifies specific experiments that allow to test whether
gene expression can be shifted and digit phenotypes can be altered by induced
digit loss or digit gain.'

text: Mechanically coupled cells can generate forces driving cell and tissue morphogenesis
during development. Visualization and measuring of these forces is of major importance
to better understand the complexity of the biomechanic processes that shape cells
and tissues. Here, we describe how UV laser ablation can be utilized to quantitatively
assess mechanical tension in different tissues of the developing zebrafish and
in cultures of primary germ layer progenitor cells ex vivo.

text: Kupffer's vesicle (KV) is the zebrafish organ of laterality, patterning the
embryo along its left-right (LR) axis. Regional differences in cell shape within
the lumen-lining KV epithelium are essential for its LR patterning function. However,
the processes by which KV cells acquire their characteristic shapes are largely
unknown. Here, we show that the notochord induces regional differences in cell
shape within KV by triggering extracellular matrix (ECM) accumulation adjacent
to anterior-dorsal (AD) regions of KV. This localized ECM deposition restricts
apical expansion of lumen-lining epithelial cells in AD regions of KV during lumen
growth. Our study provides mechanistic insight into the processes by which KV
translates global embryonic patterning into regional cell shape differences required
for its LR symmetry-breaking function.

text: A variety of developmental and disease related processes depend on epithelial
cell sheet spreading. In order to gain insight into the biophysical mechanism(s)
underlying the tissue morphogenesis we studied the spreading of an epithelium
during the early development of the zebrafish embryo. In zebrafish epiboly the
enveloping cell layer (EVL), a simple squamous epithelium, spreads over the yolk
cell to completely engulf it at the end of gastrulation. Previous studies have
proposed that an actomyosin ring forming within the yolk syncytial layer (YSL)
acts as purse string that through constriction along its circumference pulls on
the margin of the EVL. Direct biophysical evidence for this hypothesis has however
been missing. The aim of the thesis was to understand how the actomyosin ring
may generate pulling forces onto the EVL and what cellular mechanism(s) may facilitate
the spreading of the epithelium. Using laser ablation to measure cortical tension
within the actomyosin ring we found an anisotropic tension distribution, which
was highest along the circumference of the ring. However the low degree of anisotropy
was incompatible with the actomyosin ring functioning as a purse string only.
Additionally, we observed retrograde cortical flow from vegetal parts of the ring
into the EVL margin. Interpreting the experimental data using a theoretical distribution
that models the tissues as active viscous gels led us to proposen that the actomyosin
ring has a twofold contribution to EVL epiboly. It not only acts as a purse string
through constriction along its circumference, but in addition constriction along
the width of the ring generates pulling forces through friction-resisted cortical
flow. Moreover, when rendering the purse string mechanism unproductive EVL epiboly
proceeded normally indicating that the flow-friction mechanism is sufficient to
drive the process. Aiming to understand what cellular mechanism(s) may facilitate
the spreading of the epithelium we found that tension-oriented EVL cell divisions
limit tissue anisotropy by releasing tension along the division axis and promote
epithelial spreading. Notably, EVL cells undergo ectopic cell fusion in conditions
in which oriented-cell division is impaired or the epithelium is mechanically
challenged. Taken together our study of EVL epiboly suggests a novel mechanism
of force generation for actomyosin rings through friction-resisted cortical flow
and highlights the importance of tension-oriented cell divisions in epithelial
morphogenesis.

text: It is firmly established that interactions between neurons and glia are fundamental
across species for the correct establishment of a functional brain. Here, we found
that the glia of the Drosophila larval brain display an essential non-autonomous
role during the development of the optic lobe. The optic lobe develops from neuroepithelial
cells that proliferate by dividing symmetrically until they switch to asymmetric/differentiative
divisions that generate neuroblasts. The proneural gene lethal of scute (l9sc)
is transiently activated by the epidermal growth factor receptor (EGFR)-Ras signal
transduction pathway at the leading edge of a proneural wave that sweeps from
medial to lateral neuroepithelium, promoting this switch. This process is tightly
regulated by the tissue-autonomous function within the neuroepithelium of multiple
signaling pathways, including EGFR-Ras and Notch. This study shows that the Notch
ligand Serrate (Ser) is expressed in the glia and it forms a complex in vivo with
Notch and Canoe, which colocalize at the adherens junctions of neuroepithelial
cells. This complex is crucial for interactions between glia and neuroepithelial
cells during optic lobe development. Ser is tissue-autonomously required in the
glia where it activates Notch to regulate its proliferation, and non-autonomously
in the neuroepithelium where Ser induces Notch signaling to avoid the premature
activation of the EGFR-Ras pathway and hence of L9sc. Interestingly, different
Notch activity reporters showed very different expression patterns in the glia
and in the neuroepithelium, suggesting the existence of tissue-specific factors
that promote the expression of particular Notch target genes or/and a reporter
response dependent on different thresholds of Notch signaling.

text: Epithelial spreading is a common and fundamental aspect of various developmental
and disease-related processes such as epithelial closure and wound healing. A
key challenge for epithelial tissues undergoing spreading is to increase their
surface area without disrupting epithelial integrity. Here we show that orienting
cell divisions by tension constitutes an efficient mechanism by which the enveloping
cell layer (EVL) releases anisotropic tension while undergoing spreading during
zebrafish epiboly. The control of EVL cell-division orientation by tension involves
cell elongation and requires myosin II activity to align the mitotic spindle with
the main tension axis. We also found that in the absence of tension-oriented cell
divisions and in the presence of increased tissue tension, EVL cells undergo ectopic
fusions, suggesting that the reduction of tension anisotropy by oriented cell
divisions is required to prevent EVL cells from fusing. We conclude that cell-division
orientation by tension constitutes a key mechanism for limiting tension anisotropy
and thus promoting tissue spreading during EVL epiboly.

text: The spatiotemporal control of cell divisions is a key factor in epithelial
morphogenesis and patterning. Mao et al (2013) now describe how differential rates
of proliferation within the Drosophila wing disc epithelium give rise to anisotropic
tissue tension in peripheral/proximal regions of the disc. Such global tissue
tension anisotropy in turn determines the orientation of cell divisions by controlling
epithelial cell elongation.

text: Cadherins are transmembrane proteins that mediate cell–cell adhesion in animals.
By regulating contact formation and stability, cadherins play a crucial role in
tissue morphogenesis and homeostasis. Here, we review the three major unctions
of cadherins in cell–cell contact formation and stability. Two of those functions
lead to a decrease in interfacial ension at the forming cell–cell contact, thereby
promoting contact expansion — first, by providing adhesion tension that lowers
interfacial tension at the cell–cell contact, and second, by signaling to the
actomyosin cytoskeleton in order to reduce cortex tension and thus interfacial
tension at the contact. The third function of cadherins in cell–cell contact formation
is to stabilize the contact by resisting mechanical forces that pull on the contact.

abstract:
- lang: eng
text: During development, mechanical forces cause changes in size, shape, number,
position, and gene expression of cells. They are therefore integral to any morphogenetic
processes. Force generation by actin-myosin networks and force transmission through
adhesive complexes are two self-organizing phenomena driving tissue morphogenesis.
Coordination and integration of forces by long-range force transmission and mechanosensing
of cells within tissues produce large-scale tissue shape changes. Extrinsic mechanical
forces also control tissue patterning by modulating cell fate specification and
differentiation. Thus, the interplay between tissue mechanics and biochemical
signaling orchestrates tissue morphogenesis and patterning in development.

text: Motile cilia perform crucial functions during embryonic development and throughout
adult life. Development of organs containing motile cilia involves regulation
of cilia formation (ciliogenesis) and formation of a luminal space (lumenogenesis)
in which cilia generate fluid flows. Control of ciliogenesis and lumenogenesis
is not yet fully understood, and it remains unclear whether these processes are
coupled. In the zebrafish embryo, lethal giant larvae 2 (lgl2) is expressed prominently
in ciliated organs. Lgl proteins are involved in establishing cell polarity and
have been implicated in vesicle trafficking. Here, we identified a role for Lgl2
in development of ciliated epithelia in Kupffer's vesicle, which directs left-right
asymmetry of the embryo; the otic vesicles, which give rise to the inner ear;
and the pronephric ducts of the kidney. Using Kupffer's vesicle as a model ciliated
organ, we found that depletion of Lgl2 disrupted lumen formation and reduced cilia
number and length. Immunofluorescence and time-lapse imaging of Kupffer's vesicle
morphogenesis in Lgl2-deficient embryos suggested cell adhesion defects and revealed
loss of the adherens junction component E-cadherin at lateral membranes. Genetic
interaction experiments indicate that Lgl2 interacts with Rab11a to regulate E-cadherin
and mediate lumen formation that is uncoupled from cilia formation. These results
uncover new roles and interactions for Lgl2 that are crucial for both lumenogenesis
and ciliogenesis and indicate that these processes are genetically separable in
zebrafish.
