Figure 5. Effects of dipeptidyl peptidase-like protein-6 (DPP6) overexpression on Purkinje fiber cells (PC) and ventricular muscle (VM) Ito.

Figure 5

A and B, Ito recordings obtained with 100-millisecond depolarizations from −50 mV at 0.1 Hz in VMs and PCs infected with Adv-GFP-CTL (CTL) or Adv-GFP-DPP6 (DPP6). C and E, Mean±SEM Ito density-voltage relations in CTL or DPP6 from VMs (C) and PCs (E). D and F, Percentage inhibition by 10 mmol/L tetraethylammonium (TEA) of VM (D) or PC (F) Ito at 50 mV. *P<0.05, CTL vs DPP6. GFP indicates green fluorescent protein; and T P, test potential.
