Effect of inhibiting IP3 metabolism on cold shock-induced [Ca2+]cyt transients in WT and cbl9 mutants.
(a) Effect of LiCl pretreatment for 30 min on cold shock-induced [Ca2+]cyt changes in WT and cbl9 mutants. A representative trace is shown. (b) The averages of [Ca2+]cyt at the peaks (WT, n = 8; cbl9, n = 8) in (a) were shown. Asterisks indicate a significant difference (P < 0.05, t test) between WT and cbl9 mutants.
