• Steroid hormones are important chemical carriers of information for the long-term and global control of cellular functions. They control the growth as well as the differentiation and function of many organs. On the other hand, they can also have negative effects and the formation and proliferation of diseases in the organism such. For example, mammalian and prostatic carcinomas (Deroo, BJ et al., J. Clin Invest, 116: 561-570 (2006); Fernandez, SV et al., Int J. Cancer, 118: 1862-1868 (2006) )). The biosynthesis of steroids takes place in the testes or in the ovaries, where sex hormones are formed. In the adrenal glands, the display of gluco- and mineralocorticoids also takes place.
• 17ß hydroxysteroid dehydrogenase type 1 (17ß-HSDl), which catalyzes the conversion of estrone to estradiol, is increasingly found in endomeric tissue and breast cancer cells, while at the same time there is a deficiency of 17ß-HSD type 2, which catalyzes the reverse reaction occurs (Bulun, S.

• a major class of steroid hormones is formed by the estrogens, the female sex hormones whose biosynthesis v. a. runs in the ovaries and reaches its maximum immediately before ovulation. Estrogens also occur in adipose tissue, muscles and some tumors. The main tasks include a genital effect, d. h the development and maintenance of female sexual characteristics as well as an extragenital lipid-anabolic effect leading to the development of subcutaneous adipose tissue. In addition, they are involved in the development and proliferation of estrogen-dependent diseases such.
