Cryo-EM and chemical cross-linking studies yield an atomic resolution structure of a conserved remodeling machinery in messenger ribonucleoprotein maturation/nuclear export and insights into its coordinated function with a serine–arginine protein.
Proximity labeling-based proteomic strategies applied in zebrafish identify new insights into protein network changes in heart muscle cells during regeneration and implicate Rho A as a target of ErbB2 signaling during zebrafish heart regeneration.
ATF4 is a metabolic effector of mTORC1 signaling, co-opted to induce gene targets involved in amino acid synthesis, uptake, and tRNA charging, contributing to mTORC1-driven protein and glutathione synthesis.
Inducing neuronal mitochondrial activity during central nervous system inflammation counteracts inflammation-induced neuronal electron transport chain deficiency and calcium toxicity, thereby protecting against neuronal loss in a multiple sclerosis mouse model.
Stratification of COVID19 patients using quantitative metrics of seroconversion reveals distinct pathophysiological stages after SARS-CoV-2 infection, including key differences in immune cell types, inflammatory makers, and markers of organ function.
