“5′ AMP-activated protein kinase or AMPK or 5′ adenosine monophosphate-activated protein kinase is an enzyme (EC 2.7.11.31) that plays a role in cellular energy homeostasis, largely […]

SIRT1 stands for sirtuin (silent mating type information regulation 2 homolog) 1 (S. cerevisiae), referring to the fact that its sirtuinhomolog (biological equivalent across species) in […]

FOXO3 belongs to the O subclass of the forkhead family of transcription factorswhich are characterized by a distinct fork head DNA-binding domain. There are three other […]

Regulation of longevity by FGF21: Interaction between energy metabolism and stress responses. Fibroblast growth factor 21 (FGF21) is a hormone-like member of FGF family which controls […]

Klotho is a transmembrane protein that, in addition to other effects, provides some control over the sensitivity of the organism to insulin and appears to be […]

Crucial role of p53-dependent cellular senescence in suppression of Pten-deficient tumorigenesis Human SIR2 deacetylates p53 and antagonizes PML/p53‐induced cellular senescence Senescence and tumour clearance is triggered […]

Hsp90 (heat shock protein 90) is a chaperone protein that assists other proteins to fold properly, stabilizes proteins against heat stress, and aids in protein degradation. It also stabilizes a number of proteins […]
