The aims of the present study were to determine potencies of a series of environmentally relevant PCB congeners to inhibit GJIC invitro, and to screen for intrcellular signaling pathways potentially involved in GJIC downregulation by PCBs. It was found that a number of nonplanar PCB congeners are efficient inhibitors of GJIC in vitro, and that a model compound, PCB153, does not act via activation of PKC or ERK1/2, which is contrast with the effects of protoypical inhibitors of GJIC, such as TPA or EGF.
