miR-598 in senescence

miR-598 has been shown to directly target and inhibit the Sir2 homolog, silent information regulator one (SRT1) enzyme, in the senescence of human adipose-tissue-derived mesenchymal stem cells. Increased miR-598 expression during the senescent state is accompanied by a decreased expression of SRT1, meaning an absence of the inhibited p53 acetylation usually observed with increased STR1 levels.[1] miR-598 acts to modulate cellular senescence. More specifically, its overexpression induces senescence in early-passage cells whilst inhibition conversely sees a partial recovery of the ageing phenotype through increased cellular differentiation.

gollark: Oh, okay then.
gollark: However, consider the following.
gollark: Interesting.
gollark: If your brain loses oxygen input for something like 10 seconds, you become unconscious, and it fully shuts down given a few minutes or something like that.
gollark: Oxygen is needed to run aerobic respiration. Aerobic respiration is needed by lots of body stuff - muscles can run on anaerobic respiration for a bit, but not things like the brain.
