Recent work has shown that estrogen receptor mRNA and protein co‐localize with neurotrophin receptor systems in the developing basal forebrain. In the present study we examined the potential for reciprocal regulation of estrogen and neurotrophin receptor systems by their ligands in a prototypical neurotrophin target, the PC12 cell. usingin situhybridization histochemistry, RT‐PCR and a modified nuclear exchange assay, we found both estrogen receptor mRNA and estrogen binding in PC12 cells. Moreover, while estrogen binding was relatively low in naive PC12 cells, long‐term exposure to NGF enhanced estrogen binding in these cells by sixfold. Furthermore, concurrent exposure to estrogen and NGF receptor mRNAs deifferentially regulated the expression of the two NGF receptor mRNAs. The expression oftrkAmRNA was up‐regulated, while p75NGFRmRNA was down‐regulated transiently. The present data indicate that NGF may increase neuronal sensitivity to estrogen, and that estrogen, by differentially regulating p75NGFRandtrkAmRNA, may alter the ratio fo the two NGF receptors, and, conseuqnetly, neurotrophin responsivity. In view of the widespread co‐localization of estrogen and neurotrophin receptor systems in the developing CNS, the reciprocal regulation of these receptor systems by NGF and estrogen may have important implications for processes governing neural maturation and the maintenance of neural funciton. 1994 John Wiley & Sons, Inc.
