Description
| - In this study we analyzed the effects of 2,2´,4,4´,5,5´-hexachlorobiphenyl (PCB 153) on proteins involved in the formation of adherens junctions in WB-F344 cells. PCB 153 induced a gradual degradation of E-adherin, beta-catenin or plakoglobin proteins. PCB 153 had no effect on mRNA levels of the above mentioned proteins. PCB 153 also decreased levels of the active beta-catenin form, which is the key co-activator of Wnt-induced TCF/LEF-dependent gene expression and reduced Axin2 mRNA, a known Wnt signaling transcriptional target. Nevertheless, PCB 153 had no effect on phosphorylation of glycogen synthase kinase-3beta, which is supposed to target beta-catenin for its proteasomal degradation. Taken together, the present data suggest that PCB 153 may interfere with functions of adherens junction proteins involved in both cell-to-cell communication and intracellular signaling. Such mechanisms might be involved in the effects of non-dioxin-like PCBs contributing to liver tumor promotion.
