AMP-ACTIVATED PROTEIN KINASE FORTIFIES EPITHELIAL TIGHT JUNCTIONS DURING ENERGETIC STRESS VIA ITS EFFECTOR GIV/GIRDIN

AMP-activated protein kinase fortifies epithelial tight junctions during energetic stress via its effector GIV/Girdin

Loss of epithelial polarity impacts organ development and function; it is also oncogenic.AMPK, a key sensor of metabolic stress stabilizes cell-cell junctions and maintains epithelial polarity; its activation by Metformin protects the epithelial barrier against stress and suppresses tumorigenesis.How AMPK protects the epithelium remains unknown.Her

Phenotypic and genetic consequences of protein damage.

Although the genome contains all the information necessary for maintenance and perpetuation of life, it is the proteome that repairs, duplicates and expresses the genome and actually performs most cellular functions.Here we reveal strong phenotypes of physiological oxidative proteome damage at the functional and genomic levels.Genome-wide mutations
