A comprehensive molecular description of the cellular transition into replicative senescence provides evidence of metabolic, epigenetic, and regulatory rewiring that links senescence with wound healing and fibrosis.

The sphingosine 1-phosphate receptor-1 (S1PR1) signals in heterogenous populations of mouse adventitial lymphatic (LEC) and arterial endothelial cells (aEC1, aEC2) to regulate chromatin and the transcriptome, thus affecting their phenotypes.
A detailed analysis of protein abundance and phosphorylation changes across mitotic subphases and interphase in asynchronously growing human cells has been enabled by combining FACS with quantitative MS-based proteomics.
GRAMD1 proteins sense a transient expansion of the accessible pool of plasma membrane cholesterol and facilitate its transport to the endoplasmic reticulum at ER-PM contact sites.
Enteroendocrine cells sense nutrients in the gut and regulate digestive physiology but are rendered insensitive following fat ingestion due to alteration of gut microbiota.
TGN46 is a cargo receptor, with its luminal domain being necessary and sufficient to load soluble secretory proteins into transport carriers for export out of the trans-Golgi network.
