Abstract：
BACKGROUND:Protein kinase C (PKC) activity is increased and gap junctional intercellular communication (GJIC) is decreased frequently in Ras-transformed cells. We investigated the roles of Ras and PKC in the deficient gap junctional intercellular communication (GJIC) of K-ras-transformed E9 mouse lung carcinoma cells. METHODS:GJIC was measured by fluorescent dye microinjection. Ras activity was blocked with lovastatin or a K-ras antisense oligonucleotide. PKC activity was inhibited with GF 109203X or apigenin or was downregulated by overnight treatment with 12-O-tetradecanoylphorbol-13-acetate. The content and phosphorylation of the gap junction protein, connexin43 (Cx43), was assessed by Western blot. RESULTS:E9 cell GJIC was increased two-three fold by lovastatin, the K-ras antisense oligonucleotide, and PKC inhibition/downregulation. Cx43 content and phosphorylation were unchanged, however. CONCLUSIONS:Oncogenic Ras blocks GJIC in E9 cells through a PKC-dependent mechanism, but this does not directly involve Cx43 expression or phosphorylation.
