摘要: The two genes coding for thyroid hormone receptors (TR) alpha 1 and beta have opposite effects on female sex behaviors. Deletion of TRalpha reduced them, whereas deletion TRbeta actually increased them. These results could not be attributed to altered levels hormones in the blood, general alterations estrogen responsiveness or activity. Instead, they indicate a previously unknown molecular mechanism upon which TR exert influences.
