Thyroid hormones (THs) are important for brain development, and polychlorinated biphenyl (PCB) accumulation in humans is a serious problem because PCBs may affect TH functions. To determine the effects of hydroxylated metabolites of PCBs (OH-PCBs) on brain development, we performed mouse cerebellar culture assays. 4-OH-2',3,3,4,5-pentachlorobiphenyl and 4-OH-2,3,3',4',5,5'-hexachlorobiphenyl significantly inhibited the TH-dependent extension of Purkinje cell dendrites even at 5 x 10(-11) M and 5 x 10(-12) M, respectively. OH-PCBs may disturb TH-dependent brain development. (C) 2004 Elsevier B.V. All rights reserved.
