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.
A mutant impaired for ribosome recycling exhibits translational reprogramming wherein strong mRNAs outcompete weak mRNAs, also observed when preinitiation complexes are diminished by eIF2α phosphorylation or 40S ribosomal subunit depletion.
Replication origins are established throughout the genome with the exception of transcribed genes, and the local chromatin composition likely modulates the density of ORC and MCM as well as origin activation.
SWELL1 is required for basal, stretch, and flow-mediated endothelial AKT-eNOS signaling in vitro and protects against angiotensin-induced hypertension and diabetes-associated vascular dysfunction in vivo.
Knocking out Folliculin (FLCN) in human renal epithelial cells activates STAT1/2-mediated gene expression, independent of interferon, uncovering a tissue-specific process potentially relevant in the cancer syndrome Birt-Hogg-Dubé (BHD).
