Apoptosis induction and beta-spectrin expression in Huh7 and 1MEA cells.
a. Expression of survivin, LC3-I, LC3-II, cleaved caspase 7,
cleaved caspase 9 and cleaved PARP in Huh7 cells treated with or without AIP-1
and AIP-2. b Expression of survivin, LC3-I, LC3-II, cleaved caspase
3, cleaved caspase 7 and cleaved PARP in 1MEA cells treated with or without
AIP-1 and AIP-2. c Expression of beta-spectrin in Huh7 cells
treated with or without AIP-1, AIP-2 and sorafenib. d After
overnight culture, SNJ-1945, BT-1103 and EDTA were added to cells at different
doses for 30 min, after which 10 µM AIP-1 was added. Cell lysates were
resolved by SDS-PAGE and immunoblotted with a β II spectrin specific
antibody. β-actin was used as a loading control. Representative Western
blots are shown of β II spectrin breakdown products corresponding to 110
kD and 85 kD bands in 1MEA cells (upper panel) and Huh7 cells
(lower panel)
