Changes in gap junctional connexin isoforms during prostate cancer progression

Abstract excerpt

BACKGROUND: Connexins have their traditional function as part of gap junction (GJ) structures, but have recently been shown to have GJ-independent roles. Although GJs and their connexin subunits are thought to be down-regulated in cancer, depending on the connexin examined, many times the expression level is preserved or even increased. This is further apparent by the importance of GJs in "bystander effects" of...
