Mechanisms of actionRegulation of substrates and pathwaysRoles in diseasesResearch objectsReferences
SIRT1↑NAD+/NADH
↓UCP2
RSV, increasing NAD/NADH ratio and further regulating the SIRT1/UCP2 axis, protects β-cells against ethanol-induced dysfunction.Protects β-cell function under ethanol exposure.Rat insulinoma INS-1 cells[55]
SIRT1↓FOXO1
↓NF-κB
SIRT1 via deacetylating FOXO1 and the NF-κB subunit p65 represses oxidative stress-induced hyperglycemia.Overexpression of SIRT1 prevents cytokine toxicity and maintains normal insulin-secreting responses to glucose.RINm5F cells and rat islets[59]
SIRT1↑AMPK
↑PGC-1α
↑SOD1
↑SOD2
RSV treatment increased the AMPK and SIRT1 and decreased PI3K-Akt signaling to improve diabetes-induced renal damage.Reduce renal cell death and oxidative stress induced by type 2 diabetes mellitus.C57BLKS/J db/m and db/db mice[57]
SIRT3↑SIRT3
↑TFAM
↑ATP
↓TGF-β/Smad
RSV activates SIRT3, SIRT3 indirectly affects glucose metabolism by decreasing the acetylation status of TFAM, maintaining the stability of mitochondrial function.Regulates the acetylation status of TFAM and preserves the mitochondrial function along with cellular size in the diabetic rat heart.Rat-cardiomyoblast cells (H9C2)[58]
