Abstract

Understanding the mechanisms regulating development requires a quantitative characterization of cell processes including cell divisions, rearrangements, cell size and shape changes, and apoptoses. We developed a multiscale formalism that unifies and relates the characterizations of each individual cell process and of epithelial tissue growth and morphogenesis during development. We applied this formalism to two Drosophila proliferative tissues and by analyzing more than 9 million cell contours, we obtained comprehensive statistical maps of morphogenetic events linking cell and tissue scale dynamics. By quantifying each cell process separately in both wild-type and mutant conditions, we analyzed the roles of cell proliferation and its interplay with cell rearrangements and cell shape changes. Furthermore, by combining the formalism with mechanical stress measurement, we uncovered unexpected interplays between the patterns of tissue elongation, cell division orientation and stress orientations. Collectively, our formalism provides a novel and rigorous approach to uncover mechanisms governing tissue development.

    Exceptional stability of a perilipin on lipid droplets depends on its polar residues, suggesting multimeric assembly

    Manuel Giménez-Andrés et al.
    Research Article

    Numerous proteins target lipid droplets (LDs) through amphipathic helices (AHs). It is generally assumed that AHs insert bulky hydrophobic residues in packing defects at the LD surface. However, this model does not explain the targeting of perilipins, the most abundant and specific amphipathic proteins of LDs, which are weakly hydrophobic. A striking example is Plin4, whose gigantic and repetitive AH lacks bulky hydrophobic residues. Using a range of complementary approaches, we show that Plin4 forms a remarkably immobile and stable protein layer at the surface of cellular or in vitro generated oil droplets, and decreases LD size. Plin4 AH stability on LDs is exquisitely sensitive to the nature and distribution of its polar residues. These results suggest that Plin4 forms stable arrangements of adjacent AHs via polar/electrostatic interactions, reminiscent of the organization of apolipoproteins in lipoprotein particles, thus pointing to a general mechanism of AH stabilization via lateral interactions.

    Ligand sensing enhances bacterial flagellar motor output via stator recruitment

    Farha Naaz et al.
    Research Article

    It is well known that flagellated bacteria, such as Escherichia coli, sense chemicals in their environment by a chemoreceptor and relay signals via a well-characterised signalling pathway to the flagellar motor. It is widely accepted that the signals change the rotation bias of the motor without influencing the motor speed. Here, we present results to the contrary and show that the bacteria is also capable of modulating motor speed on merely sensing a ligand. Step changes in concentration of non-metabolisable ligand cause temporary recruitment of stator units leading to a momentary increase in motor speeds. For metabolisable ligand, the combined effect of sensing and metabolism leads to higher motor speeds for longer durations. Experiments performed with mutant strains delineate the role of metabolism and sensing in the modulation of motor speed and show how speed changes along with changes in bias can significantly enhance response to changes in its environment.

    Topological signatures in regulatory network enable phenotypic heterogeneity in small cell lung cancer

    Lakshya Chauhan et al.
    Research Article Updated

    Phenotypic (non-genetic) heterogeneity has significant implications for the development and evolution of organs, organisms, and populations. Recent observations in multiple cancers have unraveled the role of phenotypic heterogeneity in driving metastasis and therapy recalcitrance. However, the origins of such phenotypic heterogeneity are poorly understood in most cancers. Here, we investigate a regulatory network underlying phenotypic heterogeneity in small cell lung cancer, a devastating disease with no molecular targeted therapy. Discrete and continuous dynamical simulations of this network reveal its multistable behavior that can explain co-existence of four experimentally observed phenotypes. Analysis of the network topology uncovers that multistability emerges from two teams of players that mutually inhibit each other, but members of a team activate one another, forming a ‘toggle switch’ between the two teams. Deciphering these topological signatures in cancer-related regulatory networks can unravel their ‘latent’ design principles and offer a rational approach to characterize phenotypic heterogeneity in a tumor.
