| Outline of Final Research Achievements |
We investigated the cytotoxic effect of Cholix on HepG2 cells in the presence or absence of an inflammatory cytokine. Cytotoxicity of Cholix was dramatically enhanced with a cytokine in HepG2 cells. The mechanism of Cholix-induced cell death was involved in the signal transduction of MAPK, PKC or AMPK. In addition, we made a new peptide antibody for Cholix to identify the receptors on cell surface by immunoprecipitation. After biotin-labeled cell lysates were incubated with Cholix in the presence of anti-cholix peptide antibody, Cholix interaction proteins were detected by Western blotting using avidin-HRP. We observed two bands, which proteins were analyzed by TOF-Ms/Ms analysis.However, we could not identify these proteins. Now, we collect these bands to analyze again.
