CaM/CaMKII and Nrf2/HO‐1/NQO1 signaling pathways were attenuated after YWHAE knockdown. (a) Changes in 14‐3‐3ε, t‐Nrf2, n‐Nrf2, HO‐1, NQO1, CaM, p‐CaMKII, CaMKII, p16INK4a, and p21 expression in hAMSCs upon different treatments. (b–i) Relative expression levels of 14‐3‐3ε, n‐Nrf2, t‐Nrf2, CaM, CaMKII, p‐CaMKII, HO‐1, NQO1, p16INK4a, and p21. N = 3. N‐Nrf2, nuclear Nrf2; t‐Nrf2, total Nrf2; p‐CaMKII, phosphorylated CaMKII; control, control group; H2O2, senescent group; GA‐D, GA‐D treatment group; mock‐vehicle, GA‐D treatment group plus empty carrier; h‐14‐3‐3ε, GA‐D treatment group plus YWHAE overexpression; sh‐14‐3‐3ε, GA‐D treatment group plus YWHAE knockdown; , mean ± standard deviation. *p < 0.05, **p < 0.01. CaM, calmodulin; CaMKII, CaM‐dependent protein kinase II; GA‐D, ganoderic acid D; H2O2, hydrogen peroxide; hAMSC, human amniotic mesenchymal stem cell; Nrf2, nuclear erythroid 2‐related factor 2.
