Combined intracellular and transepithelial potential and resistance measurements were performed to localize the ion conductances activated by hypo-osmotic shock of cultured human colonic carcinoma cells (HT-29Cl.19A). Furthermore, the effect of cell

Cell-attached patch-clamp studies with the human colon carcinoma HT-29cl.19A cells revealed a small chloride channel with a unitary conductance of 6.5 pS at 70 mV and 4.6 pS at −70 mV clamp potential after cAMP was increased by activation of adenyl

The differentiated clone 19A of the HT-29 human colon carcinoma cell line was used as a model to study the intracellular electrophysiological effects of interaction of the cAMP, the protein kinase C (PKC) and the Ca2+ pathways. (a) A synergistic effe
