The membrane currents of chicken embryo fibroblasts (CEFs) transformed by Rous sarcoma virus (RSV) were compared with the currents of their nontransformed counterparts by using the whole-cell patch-clamp technique. In nontransformed CEFs, the main membrane current is a delayed outward K+ current
Ion channels in normal and Rous sarcoma virus (RSV)-transformed chicken embryo fibroblasts (CEFs) were examined by using the patch-clamp technique. Three different types of ion channels were observed with single-channel conductances in symmetrical 140 mM KCl (with frequencies of occurrence in
To study the role of the inositol 1,3,4,5-trisphosphate-binding protein GAP1(IP4BP) in store-operated Ca2+ entry, we established a human erythroleukemia (HEL) cell line in which the expression of GAP1(IP4BP) was substantially reduced by transfection with a vector containing antisense DNA under
