Mitogen-activated protein kinase (MAPK) cascades have emerged as a universal signal transduction mechanism that connects diverse receptors/sensors to cellular and nuclear responses in eukaryotes. Recent studies in plants indicate that MAPK cascades are vital to fundamental physiological functions involved in hormonal responses, cell cycle regulation, abiotic stress signaling, and defense mechan...

A large number of G protein-coupled receptors are palmitoylated on cysteine residues located in their carboxyl tail, but the general role of this post-translational modification remains poorly understood. Here we show that preventing palmitoylation of the V2 vasopressin receptor, by site-directed mutagenesis of cysteines 341 and 342, significantly delayed and decreased both agonist-promoted rec...

The families ofMAP kinases cascades (mitogen activated protein kinases) form major signalling systems by which cells transduce extracellular signals into cellular responses. Studying the regulation of these MAP kinase signalling pathways is of utmost importance in the understanding of the triggering of cell proliferation versus cell differentiation and the responses of the cell to stress or osm...

An improved understanding of pathogenic pathways may identify novel acute kidney injury (AKI) therapeutic approaches. Unbiased LC-MS/MS protein expression profiling combined with focused data mining identified MAP3K14 and non-canonical NFκB activation at the crossroads of the enriched pathways MAPK, ubiquitin-mediated proteolysis, chemokines, NFκB and apoptosis in the kidney cortex of experimen...

Abstract Background Caffeine, an alkaloid agent, has been globally used regularly in drinks, for the reduction skin cancers and wrinkle formation. As a result of previous, attempts have carried out to use caffeine cosmetology due its antioxidant UV ray protection effects. Our aim was evaluate effect on collagen resynthesis via proline prolidase biosynthesis mice, orally topically as mesoporous ...
