Several in vitro tests, including transcriptome analysis of neural cells, were performed to assess the capacity 39 pesticides act as thyroid hormone disruptors (THD). Although some elicit a cellular response, which interferes with signaling, we found no evidence that they can receptor agonists or antagonists. We conclude nuclear receptors are not common targets THD, and pesticide neurodevelopme...

When cultured human lymphocytes of the IM-9 line were exposed to human growth hormone (hGH) at 37 degrees, washed for 2 hours, and incubated with 125I-hGH, the binding of 125I-hGH was reduced. The magnitude of the reduction in binding was dependent on the concentration of growth hormone present as well as the duration of the exposure. As little as 2 X 10(-11) M (0.5 ng/ml) growth hormone had a ...
