The apoptosis assay and western blot analysis of poly‑ADP‑ribose polymerase, pro‑caspase 3 and pro‑caspase 8 demonstrated that silibinin synergized with paclitaxel in promoting SGC‑7901 GC cell apoptosis.
The results showed that, in the presence of dasatinib, proliferation of GC cells decreased and apoptosis increased, and that Fas-associated death domain protein and caspase-8 are essential to dasatinib-induced cell apoptosis in GC.
The occurrence of CASPASE-8 mutation and the inactivation of cell death activity by the mutants suggest that CASPASE-8 gene mutation may affect the pathogenesis of gastric cancers, especially at the late stage of gastric carcinogenesis.
Expression of FLICE-like inhibitory protein (FLIP), one of the inhibitory proteins of Fas-mediated apoptosis, has been reported in several cancer types, but not in stomach cancer.
We have analysed the genetic alteration of the entire coding region and all splice sites of caspase-8 and -10 genes in 99 gastric cancers by polymerase chain reaction (PCR)-single strand conformation polymorphism (SSCP) and sequencing.
