Figure 7. NOX5-S expression and thymidine incorporation in FLO OA cells with TGR5 overexpression.
(A) Western blot analysis and (B) summarized data showed that TGR5 protein was successfully overexpressed in FLO cells after transfection with pCDNA3.1-TGR5 (pCDNA-TGR5). (C) Western blot analysis and (D) summarized data showed that overexpression of TGR5 receptor significantly increased TDCA-induced NOX5-S expression, (E) H2O2 production and (F) thymidine incorporation. The data suggest that TDCA-induced increase in NOX5-S expression, H2O2 production and cell proliferation may depend on activation of TGR5 receptor. N=3, ANOVA, * P<0.01, ** P<0.05, compared with control plasmid pCDNA3.1 (pCDNA); *** P<0.001, #P<0.05, compared with pCDNA3.1 (pCDNA) + TDCA group.
