Smad and mtor
Webb24 maj 2024 · mTOR is a serine-threonine kinase that controls several important aspects of mammalian cell function. Changes in mTOR activity have a dramatic impact on rates of translation, transcription, protein degradation, cytoskeleton dynamics, cell metabolism, and autophagy [ 21 ]. Webb23 jan. 2024 · SMAD2/3 are the major TGF-β signaling modulators ( 28 ). We knocked down SMAD2 or SMAD3 via siRNA and monitored SIRT7 expression induced by TGF-β1.
