1 One is the demonstration that cellular 90K hsp (hsp-90) can complex with steroid receptors in vitro and inhibit their ability to interact with DNA, and second, the demonstration that in avian oviduct sex steroids can regulate the synthesis of hsp-108. Steroids heat shock protein 90 alpha family class A member 1 Homo sapiens
2 As yet, there is no report that sex steroids can regulate hsp-90 synthesis, especially in mammalian tissues. Steroids heat shock protein 90 alpha family class A member 1 Homo sapiens
3 We report that ovariectomy reduces the uterine concentration of hsp-90, and estradiol causes a time-dependent increase in uterine hsp-90 as early as 4 h after steroid administration, reaching a maximum increase of 4-fold between 18-24 h. The effect is specific to estrogens and not elicited by other steroid hormones. Steroids heat shock protein 90 alpha family class A member 1 Homo sapiens
