Effect of phlorizin on the Ca2+ concentration and GIP expression in STC-1 cells at 24 h. (A) Cell viability after 24 h treatment of phlorizin determined by MTT assay. (B) The intracellular Ca2+ concentration determined by BBcellProbe F03 assay. (C) The mRNA expression of GIP determined by RT-PCR. Different letters indicate significant difference among groups (p < 0.05). * p < 0.05, ** p < 0.01, compared with normal group.
