To study the functional interaction between CFTR and gap junction channels, we coexpressed in Xenopus oocytes CFTR and either Cx45, Cx40, Cx32 or Cx50 and monitored junctional conductance (G (j)) and its sensitivity to transjunctional voltage (V (j)) by the dual voltage-clamp method. Application of forskolin induced a Cl(-) current; increased G (j) approximately 750%, 560%, 64% and 8% in Cx45, Cx40, Cx32 and Cx50, respectively; and decreased sensitivity to V (j ) gating, monitored by a change in the ratio between G (j) steady state and G (j) peak (G (j)SS/G (j)PK) at the pulse. In oocyte pairs expressing just Cx45 in one oocyte (#1) and both Cx45 and CFTR in the other (#2), with negative pulses applied to oocyte #1 forskolin application still increased G (j) and decreased the sensitivity to V (j) gating, indicating that CFTR activation is effective even when it affects only one of the two hemichannels and that the G (j) and V (j) changes are not artifacts of decreased membrane resistance in the pulsed oocyte. COOH-terminus truncation reduced the forskolin effect on Cx40 (Cx40TR) but not on Cx32 (Cx32TR) channels. The data suggest a cross-talk between CFTR and a variety of gap junction channels. Cytoskeletal scaffolding proteins and/or other intermediate cytoplasmic proteins are likely to play a role in CFTR-Cx interaction."xsd:string |
