Generic approach to validation of small-molecule LC-MS/MS biomarker assays.

Richard Houghton et al.

Bioanalysis, 1(8), 1365-1374 (2010-11-19)

While the regulatory guidelines that describe the validation requirements for small molecules are very comprehensive, they are written primarily for xenobiotic drug molecules. However, the presence of endogenous analyte in control matrix presents an added analytical challenge that must be

Glucuronidation of the steroid enantiomers ent-17β-estradiol, ent-androsterone and ent-etiocholanolone by the human UDP-glucuronosyltransferases.

Nina Sneitz et al.

The Journal of steroid biochemistry and molecular biology, 127(3-5), 282-288 (2011-09-09)

Steroids enantiomers are interesting compounds for detailed exploration of drug metabolizing enzymes, such as the UDP-glucuronosyltransferases (UGTs). We have now studied the glucuronidation of the enantiomers of estradiol, androsterone and etiocholanolone by the 19 human UGTs of subfamilies 1A, 2A

The effect of elevated steroids released by reproductive male round gobies, Neogobius melanostomus, on olfactory responses in females.

Alyson J Laframboise et al.

Journal of chemical ecology, 37(3), 260-262 (2011-03-03)

The round goby, Neogobius melanostomus, is a highly successful invasive species in the Laurentian Great Lakes. Previous behavioral studies implied that females are attracted by pheromones to the nests of reproductive males, and that males release putative steroidal pheromones--unconjugated as

The 5α-androstanedione pathway to dihydrotestosterone in castration-resistant prostate cancer.

Nima Sharifi

Journal of investigative medicine : the official publication of the American Federation for Clinical Research, 60(2), 504-507 (2011-11-09)

The survival and progression of prostate cancer are generally dependent on expression of the androgen receptor (AR), as well as the availability of endogenous AR agonists. Originating from the gonads, testosterone is released into circulation and is converted by steroid-5α-reductase

Clinical and metabolic findings in a 6-year-old boy with a Leydig cell tumour.

S Lignitz et al.

Acta paediatrica (Oslo, Norway : 1992), 100(12), e280-e282 (2011-05-04)

To analyse the urinary steroid metabolome in a boy who had true precocious puberty after a Leydig cell tumour. Case report and detailed description of clinical and metabolic findings in a 7-year-old-boy with a Leydig cell tumour. Before surgery, the
