Knocking down Nrf2 reversed the miR‐144‐3p inhibitor‐alleviated H/R‐induced apoptosis, oxidative stress, mitochondrial damage and endoplasmic reticulum stress in vitro. A–c, F–K, The protein expression level of Nrf2, HO‐1, cleaved‐caspase3, Bax, Bcl‐2, CHOP, GRP78 and Cytochrome C in H/R‐injured TCMK cells transfected with miR‐144‐3p inhibitor or si‐Nrf2. Representative bands are shown in A, and the quantitative analysis of protein expression is shown in B, C, F–K (n = 3). D, E, The SOD and MDA levels in cellular supernatants in H/R‐injured TCMK cells transfected with miR‐144‐3p inhibitor or si‐Nrf2 (n = 3). All data are expressed as the mean ± SD; data comparisons between multiple groups were performed using one‐way analysis of variance (ANOVA) with Tukey's post hoc test. *p < 0.05, **p < 0.01, NS, no significant difference
