abstract：:In target tissue extracts, heat shock protein hsp90 has been found associated to all unliganded steroid receptors. Modulation of important functions of these receptors, including prevention of DNA binding and optimization of transcriptional activity, has been attributed to hsp90. However no unequivocal in vivo demonst...
