SAE2 expression in SCLC tissues and cell lines. a Representative immunohistochemical results of the expression of SAE2 in tumor tissues from SCLC patient (n = 20) and normal lung tissues (n = 5). b The expression of SAE2 mRNA in SCLC cell lines (H446, H146, H526 H69, and BEAS-2B). c The expression of SAE2 protein in SCLC cell lines (H446, H146, H526, H69, and BEAS-2B). Data represent means ± SEM of three independent experiments (*P < 0.05, **P < 0.01)
