There is a strong correlation between dysfunctional GJIC during the etiology of cancer. To identify alterations in GJIC, scrape loading dye assays, fluorescent recovery after photobleaching, and pre-loading dye assays were performed on MDV-infected CEFs. Each procedure relies on the passage of different dyes through gap junctions between cells if GJIC is functional. However, alterations in GJIC impedes the dye from spreading between adjacent cells. GJIC was inhibited in oncogenic MDV-infected CEFs but unaltered in attenuated and uninfected CEFs. This is the first demonstration of an oncogenic herpesvirus altering GJIC. |
