Modulation of the StAR protein and P450scc expressions in previtellogenic salmon oocytes by PCB congener 77

Previtellogenic oocytes from Atlantic salmon were exposed to different concentrations of PCB77 using an in vitro agarose culture system for 3, 7 and 14 days. Overall, our results show time- and concentration-specific effects of PCB77 on key steroidogenic enzyme, P450scc and protein, StAr at the mrNA...

Description
Summary:Previtellogenic oocytes from Atlantic salmon were exposed to different concentrations of PCB77 using an in vitro agarose culture system for 3, 7 and 14 days. Overall, our results show time- and concentration-specific effects of PCB77 on key steroidogenic enzyme, P450scc and protein, StAr at the mrNA level, as well as protein level using immu-nohistochemical analysis.
