Using high-throughput light-sheet microscopy, Dent et al. study 3D cancer cell morphogenesis. Environmental cues modulate the opposing roles of non-muscle myosin II (myosin) and microtubules, with varied impacts on RhoGEFs FARP1 and TIAM2. The study underscores the critical interplay between cytoskeletal regulators and the microenvironment, enhancing our understanding of cell behavior in diverse settings.

Distributed X chromosome inactivation in brain circuitry is associated with X-linked disease penetrance of behavior
Szelenyi et al. demonstrate that adult brain XCI is systematically biased toward maternal X-active cells, which is sufficient for disease penetrance of the X-linked Fmr1-KO allele. Furthermore, local XCI mosaicism distinguishes phenotypic outcomes of individuals based on mutant X-active cells populating […]
Genomic deletions explain the generation of alternative BRAF isoforms conferring resistance to MAPK inhibitors in melanoma
Aya et al. show that the production of alternative BRAF mRNA isoforms (altBRAFs), associated with resistance to BRAF inhibitors in melanoma, is caused by genomic deletions rather than by alternative splicing, as previously thought. They also find that altBRAFs are present […]
A fitness landscape instability governs the morphological diversity of tip-growing cells
Ohairwe et al. demonstrate that an intrinsic mechanical instability in the convergent mechanism of “inflationary” cell growth shared by diverse tip-growing cells leads to a bifurcation (branching) of their fitness landscape. This bifurcation strictly constrains natural tip-growing cell shapes.
