SIRT1 regulates glucose homeostasis and insulin secretion by repressing UCP-2 in pancreatic beta-cells, thereby promoting efficient ATP production in response to glucose.
SIRT1 helps beta-cells secrete insulin efficiently by ensuring mitochondria produce ATP effectively. This mechanism is crucial for maintaining blood sugar levels, especially after meals.
GoodSupportsHIGH confidence
SIRT1 positively regulates glucose-stimulated insulin secretion in pancreatic beta-cells... SIRT1 represses transcription of the mitochondrial uncoupling protein UCP-2 gene... by blocking UCP-2 function, SIRT1 promotes more efficient energy generation.
Why this rating
Supported by multiple studies in mice (BESTO and KO models).

- Calorie restriction extends lifespan in model organisms and mammals, and this extension requires the NAD-dependent deacetylase activity of sirtuins (specifically Sir2/SIRT1).Good
- SIRT4 regulates amino acid-stimulated insulin secretion (AASIS) by ADP-ribosylating and inhibiting glutamate dehydrogenase (GDH), linking energy limitation to insulin release.Good
