Abstract

Experiments were conducted by using scrape-loading and dye transfer (SLDT) method to study the gap junction intercellular communication (GJIC) of Chinese hamster lung cells (V79), mouse fibrous cells (Balb/c-3T3), rat liver cells (WB) and human embryonal lung cells (2BS). We also observed the inhibition of the GJIC by TPA and the antagonistic effect of Curcumin derivatives on TPA. The results indicated that V79, WB, 3T3 and 2BS normal cells showed medium level of GJIC, and TPA could inhibit the GJIC to some extents. Curcumin derivatives (91022, 91022-S) could counteract the inhibition of TPA-induced GJIC. It was also found that human lung adenocarcinoma cell (A549) and GLC lacked GJIC, and 91022 could improve the GJIC of A549 cell. It may be related to its anticancer activity.
