Apoptosis suppression
did not affect the expression regulation
of SSD on autophagy-related proteins. SGC-7901 (A) and SGC-7901/DDP
(E) cells were treated by Z-VAD-FMK at the indicated concentrations
in the presence or absence of SSD, and several apoptosis- and autophagy-related
proteins were detected by Western blot. Levels of LC3 B, p62, and
IKK β were normalized to β-actin levels in SGC-7901 (B)
and SGC-7901/DDP (F), respectively. Expression of p-IκB α
was normalized to the expression of total IκB α in SGC-7901
(C) and SGC-7901/DDP (G), respectively. Level of cleaved caspase 3
was normalized to the level of pro-caspase 3 in SGC-7901 (D) and SGC-7901/DDP
(H), respectively. *p < 0.05, **p < 0.01, compared with control.
