A time-resolved interaction analysis of Bem1 reconstructs the flow of Cdc42 during polar growthA temporal dissection correlates changes in composition and architecture of the interaction network of Bem1 with changes in cellular morphology and the activities of its binding partners.
BH4 activates CaMKK2 and rescues the cardiomyopathic phenotype in rodent models of diabetesThis study reports that BH4 activates CaMKK2/PGC-1α; signaling pathway and has a therapeutic effect on diabetic cardiomyopathy.
A paralog-specific role of COPI vesicles in the neuronal differentiation of mouse pluripotent cellsThe paralogous COPI coat subunit γ1-COP plays a unique role in promoting neurite outgrowth during the neuronal differentiation of mouse pluripotent cells.
Attenuation of cGAS/STING activity during mitosisTo limit deleterious interferon responses with each cell division and open mitosis, cGAS/STING activities are shown to be dampened-with Golgi vesiculation preventing activation of STING.
USP30 sets a trigger threshold for PINK1–PARKIN amplification of mitochondrial ubiquitylationA new inhibitor of the deubiquitylase USP30, an actionable target relevant to Parkinson’s Disease, is introduced and characterised for parameters related to mitophagy.
Small molecule inhibitors and a kinase-dead expressing mouse model demonstrate that the kinase activity of Chk1 is essential for mouse embryos and cancer cellsThe study use small molecule inhibitors and a kinase-dead expressing mouse model to demonstrate that the kinase activity of Chk1 is essential for mouse embryos and cancer cells.
Quantification of cristae architecture reveals time-dependent characteristics of individual mitochondriaA novel, machine-learning approach to quantify cristae density and architecture in live-cell super-resolution imaging characterizes the ultrastructural parameters of individual mitochondria over time.
Unbiased yeast screens identify cellular pathways affected in Niemann–Pick disease type CThree independent yeast genetic screens were performed identifying proteins and pathways contributing to the pathogenesis of NPC disease and suggesting new therapeutic avenues.
Genetic targeting of neurogenic precursors in the adult forebrain ventricular epitheliumIn vivo evidence for precursors that produce neurons independent of neurosphere-forming neural stem cells suggests the adult forebrain, like the developing brain, has two distinct neurogenic pathways.
STAG1 vulnerabilities for exploiting cohesin synthetic lethality in STAG2-deficient cancersThis work highlights the degradation of STAG1 and inhibition of its interaction with cohesin as promising therapeutic strategies for exploiting synthetic lethality to treat STAG2-mutated tumors and lays the groundwork for the discovery of STAG1-directed small molecules.
