Effect of IH on Ca²⁺ current in CaV3.2-HEK cells. A: representative Ca²⁺ currents from CaV3.2-HEK cells treated with either normoxia or 60 cycles of IH (IH₆₀). Currents were recorded from a holding potential of −90 to +40 mV in 10 mV steps every 10 s. B: normalized current-voltage relation of CaV3.2 currents in cells treated with normoxia and IH₆₀. C: normalized peak current density obtained with a step to −30 mV for normoxia- and IH₆₀-treated CaV3.2-HEK cells. Normoxia, n = 32 cells; IH₆₀, n = 28 cells (B and C). Data presented are means ± SE. **P < 0.01.
