Mechanically stimulating mitochondria causes them to divide via the recruitment of the mitochondrial fission machinery to the mechanically strained site, showing that intracellular organelles can be mechanoresponsive.
A genetic program controlling brain genes across the lifespan specifies a calendar of changes in cells, synapses and behavioural genes thereby timing the onset of mental illnesses which arise in young adults.
Efficient targeting of membrane proteins from the endoplasmic reticulum (ER) to the inner nuclear membrane depends on GTP hydrolysis by Atlastin GTPases and their function in maintaining an interconnected topology of the ER network.
Despite billions of years of divergence, a majority of prokaryotic genes can functionally replace their essential eukaryotic counterparts, revealing broad preservation of ancestral functions and identifying heme biosynthesis as a near-universally swappable pathway.
Atomic force microscopy based single-molecule force spectroscopy of smooth muscle myosin light chain kinase strongly indicates the existence of a mechanically triggerable activation pathway analogous to its well-established biochemical regulation pathway via calcium-loaded calmodulin.
A genetic analysis has identified the cholinergic SIA sublateral motor neurons, which innervate all four body wall muscles separately, as crucial regulators of turning around during sleep in Caenorhabditis elegans.
