Hormones in Recombinant Proteins

Applications 4-Hydroxy Estrone 1-N3-Adenine is an estrogen metabolite formed with DNA which can lead to the mutations that initiate breast, prostate, and other types of cancer. The N3Ade depurinating adducts could serve as biomarkers to predict the risk of breast cancer. References Chakravarti, D., et al.: Mutat. Res., 456, 17 (2000), Liehr, J., et al.: Endocr.

Applications Testosterone and epitestosterone are endogenous steroids that differ in the configuration of the hydroxyl-bearing carbon at C-17. Testosterone is the predominant male sex hormone, whereas the role of epitestosterone is largely unclear. In humans, both androgens are excreted mainly as glucuronide conjugates.

Applications 2-Hydroxy-estrone-6-N3-adenine is a depurinating adduct that is created by the interaction of specific metabolites of estrogens in the body with DNA. Unfortunately, these adducts are endogenous initiators of various human cancers, such as breast & prostate. References Yang, L., et al.: Prostate, 69, 41 (2009); Zahid, M., et al.: Chem. Res. Toxicol., 19, 164 (2006); Zhang, Y., et al.: Metabol. Clin. Exp., 56, 887 (2007)

Applications Labelled (3β,5α)-4,4-Dimethylcholesta-8,14,24-trien-3-ol, a follicular fluid meiosis-activating sterol (FF-MAS); a factor present in the pre-ovulatory follicle during the time of oocyte maturation. (3β,5α)-4,4-Dimethylcholesta-8,14,24-trien-3-ol has been shown to protect young oocytes from precocious chromatid separation as well as protecting aged oocytes from predivision during maturation.
