Optogenetic experiments show that bridging microtubules buffer chromosome movements and promote their alignment through forces transferred to the associated kinetochore fibers, which rely on precise regulation of the overlap region.
Mutations that affect a metabolic network generically exhibit epistasis, which propagates to higher level phenotypes, such as fitness, carrying some information about the network’s topology.
Computational, theoretical, and in vivo studies reveal that in epithelia the self-organization of apical microtubules is robustly determined by cell geometry and minus-end distribution, not organism environment or genetics.
Serial-Block-Face Scanning Electron Microscopy (SBF-SEM) associated with biomolecular analysis show that chloroplast differentiation proceeds by distinct ‘structure establishment’ and ‘chloroplast proliferation’ phases, each with differential protein and lipid regulation.
In parallel to protein-driven processes, characteristic physicochemical properties of the endoplasmic reticulum membrane modulate intracellular fat accumulation and lipid droplet formation.
Mechanochemical defects of a β-cardiac myosin mutation that results in severe hypertrophic cardiomyopathy are reported and the heart failure drug omecamtiv mecarbil rescues these defects.
Definition of leukemia gene expression mechanisms reveals general principles of cancer gene control and offers a pharmacologic strategy for its therapeutic reprogramming.
