title: Significant suppression of rat liver aldolase B by a toxic coplanar polychlorinated biphenyl, 3,3',4,4',5-pentachlorobiphenyl.
abstract: A toxic coplanar polychlorinated biphenyl, 3,3',4,4',5-pentachlorobiphenyl (PenCB), significantly suppresses the expression of liver aldolase B in rats. Hepatic aldolase activity in PenCB-treated rats was significantly reduced to about 50% of that in free- and pair-fed control groups. The reduced aldolase activity following PenCB-treatment was due to the marked suppression of the expression of aldolase B shown by immunoblot analysis after SDS-polyacrylamide gel electrophoresis and two-dimensional gel electrophoresis. The suppression of rat liver aldolase B could be a key biochemical lesion caused by PenCB.
