Effect of 5-FU on the TRPM2-modulated TE-1 cell proliferation and apoptosis. (A)
Summary data showing that 5-fluorouracil (5-FU, 5 μM; 24-h incubation) suppresses TE-1
cell proliferation and showing the effect of a TRPM2 channel inhibitor (ACA, 20 μM)
and TRPM2 siRNA (siTRPM2). Cell proliferation is detected by a CCK-8 assay and
expressed as OD. Data are shown as the mean ± SEM; n = 5.
*P < .05 versus control (Ctl);
#P < .05 versus 0 μM ACA;
&P < .05 versus siRNA control (siNC);
P > .05 versus Ctl. (B) Summary data showing the effect of 5-FU
(5 μM, incubation for 24 h) on the protein expression level of cleaved caspase-3 and
the effect of ACA and siTRPM2. β-tubulin is used as a loading control. Data are shown
as the mean ± SEM; n = 6. *P < .05 versus Ctl;
#P < .05 versus 5-FU;
&P < .05 versus siNC + 5-FU.
