Ribosomal protein L11 (RPL11) promotes non-small cell lung cancer (NSCLC) cell proliferation through endoplasmic reticulum stress (ERS) activation. (a,b) The effect of RPL11 on ERS-related protein expression levels in NSCLC cells were examined by western blotting. (c) The effect of ERS inhibitor (TUDCA) on ERS and atuophagy-related protein expression in RPL11-overexpressing NSCLC cells was detected by western blotting. The blots (a-c) were cut before hybridization with antibodies during blotting. The data are presented as mean ± SD from three independent trials (n = 3). Statistical data of a was analyzed using Student’s t-test, statistical data of b and c was analyzed using one-way ANOVA. *P < 0.05, **P < 0.01, ***P < 0.001
