Xenobiotic and steroid biotransformation activities in rainbow trout gill epithelial cells in culture.

Aquatic toxicology (Amsterdam, Netherlands)

Leguen I, Carlsson C, Perdu-Durand E, Prunet P, Pärt P, Cravedi JP.
PMID: 10686323
Aquat Toxicol. 2000 Mar 01;48(2):165-176. doi: 10.1016/s0166-445x(99)00043-0.

The biotransformation of xenobiotics and steroids was investigated in cultured respiratory epithelial cells from rainbow trout (Oncorhynchus mykiss) gills. As a first approach, ethoxyresorufin-O-deethylase (EROD), chosen as a marker of CYP1A activity, was measured in monolayers of adherent cells....

Inflammopharmacology

Kasasa SC, Soory M.
PMID: 17657621
Inflammopharmacology. 1998;6(3):223-34. doi: 10.1007/s10787-998-0021-5.

The combined effects of the growth factors, PDGF, TGF-beta and IGF, on the metabolism of two androgen substrates by human gingival tissue were investigated. Having established their wet weight, duplicate incubations were performed in Eagle's MEM using [(14)C]testosterone/[(14)C]4-androstenedione as...

Fetal fluid steroids and their relationship to gonadal steroid secretion in single and twin bovine fetuses.

Theriogenology

Domínguez MM, Liptrap RM, Basrur PK.
PMID: 16726816
Theriogenology. 1990 Jul;34(1):57-72. doi: 10.1016/0093-691x(90)90577-g.

Steroid concentrations in the fetal fluids of 153 single and 69 twin bovine pregnancies, ranging in age from 35 to 125 d of gestation, were studied to compare gonadal steroid secretions in vitro with the concentrations found in amniotic...

Evidence that Neural Aromatization of Androgen Regulates the Expression of Sexual Behaviour in Female Musk Shrews.

Journal of neuroendocrinology

Rissman EF.
PMID: 19215490
J Neuroendocrinol. 1991 Aug 01;3(4):441-8. doi: 10.1111/j.1365-2826.1991.tb00301.x.

Abstract The experiments reported on here were conducted to test the hypothesis that sexual behaviour in the female musk shrew (Suncus murinus) is regulated by the neural aromatization of testosterone to oestradiol. In the first experiment ovariectomized animals received...

The polycystic ovary syndrome (PCOS) is one of the most frequent endocrinopathies in women. Its incidence is assessed at 6-8% of the female population in the reproductive age. It is characterised by oligomenorrhea (Oligo), hyperandrogenism (HA), and the presence...

Effects of live weight and processing on the sensory traits, androstenedione concentration and 5-alpha-androst-16-en-3-one (androstenone) concentration in boar meat.

Meat science

Coker MD, West RL, Brendemuhl JH, Johnson DD, Stelzleni AM.
