Measuring Ca2+ influxes of TRPC1-dependent Ca2+ channels in HL-7702 cells with Non-invasive Micro-test Technique

Figure 3 Nifedipine and La³⁺ influence Ca²⁺ influxes of TRPC1-transfected HL-7702 cells. A: Net Ca²⁺ fluxes of a TRPC1 + nifedipine-treated cell. The maximum values were 44.0 ± 5.7 pmol/cm² per second (n = 6); B: Net Ca²⁺ fluxes of a TRPC1 + La³⁺-treated cell. The maximum values were 7.6 ± 1.9 pmol/cm² per second (n = 6); C: Bar graph of the maximum net Ca²⁺ fluxes in the TRPC1-transfected group, TRPC1 + nifedipine-treated group, and TRPC1 + La³⁺-treated group. A significant statistical difference only existed between the TRPC1-transfected group and the TRPC1 + La³⁺-treated group (^bP < 0.01).
