The expression of apoptotic proteins enhanced by NK-exosIL−15/21 in HCC cells. (A) Western blotting of the expression levels of specific pro-apoptotic proteins (Bax, caspase 3, PARP, perforin, and granzyme B) and an anti-apoptotic protein (Bcl-2). β-actin was used as a loading control. Uncropped western blots were indicated in Supplementary Fig. S4. (B–I) Quantification of protein expression normalized to that of β-actin. All data are presented as the mean ± SD (n = 3). *p < 0.05, **p < 0.01, and ***p < 0.001 vs. untreated Hep3B cells.
