TYP inhibits melatonin-enhanced SIRT3 activity but does not affect SIRT3 protein expression. 3-TYP pretreatment reverses the protective effects of melatonin on cadmium (Cd)-induced mitochondrial-derived O2•− production and autophagic cell death. 3-TYP significantly attenuates melatonin-induced increases in deacetylated-SOD2 expression and SOD2 activity in HepG2 cells exposed to Cd.
TYP (50 mg/kg, i.p.) does not significantly influence the LVEF, LVFS, infarct size, serum LDH levels, apoptosis, and oxidative stress compared with those of the Sham group. Moreover, 3-TYP has little effect on gp91phox, Nrf2, NQO 1, Bax, Bcl-2, Caspase-3, and cleaved Caspase-3 expression levels, compared with the Sham group. 3-TYP significantly decreases SIRT3 activity and increases the acetylation of SOD2 compared with that in the control group, without influencing SIRT3 expression. 3-TYP attenuates the cardioprotective effects of melatonin by decreasing the LVEF and LVFS after 24 hour of reperfusion. 3-TYP also increases the infarct size, serum LDH levels, and apoptotic ratio compared with those in the IR+Mel group.
