Transcellular Ca²⁺ transport in monolayers of CNT/CCD cells expressing cGK II. Cultured monolayers were either infected (solid bars) or not infected (open bars) with adenovirus for expressing cGK II. Two days after infection, transcellular Ca²⁺ transport was measured in the absence (control) and presence of either 100 nM ANP (basolateral), 100 μM SNP (both sides), 100 μM 8-Br-cGMP (both sides), 100 μM 8-Br-cAMP (both sides), or 10 nM d-Arg-8-vasopressin (basolateral). Values are means ± SEM (n = 6). ∗, P < 0.05, significantly different from the control values.
