Transcriptional regulation by steroid hormones - PubMed

網頁Tools. Steroid hormone receptors are found in the nucleus, cytosol, and also on the plasma membrane of target cells. They are generally intracellular receptors (typically cytoplasmic or nuclear) and initiate signal transduction for steroid hormones which lead to changes in gene expression over a time period of hours to days. 網頁Steroid Hormones and Their Receptors. Steroid hormones and their receptors include estrogens, progesterone, and androgens. They are manufactured from one common parent molecule, cholesterol, via a reaction catalyzed by several enzymes (Weinberg et al., 2005 ). Estrogen is produced by two different organ systems. 48新台币網頁2005年6月1日 · Similar to estrogen, other steroid hormones (progestins, androgens, and glucocorticoids) also autoregulate the expression of their receptor genes by altering mRNA stabilities ().
