Quantification of Kv11.1-HA-WT (red bars) or Kv11.1-HA-S890A (blue bars) surface expression in CHO cells in response to 200 pM PMA for 2 h or PMA + PKC 20–28 or in cells expressing shRNA PKCα and compared with untreated cells. Each value represents the mean ± S.E. of at least six determinants in eight independent experiments. *, significant difference from the control (untreated) (P < 0.001, t test).
