Histology and histopathology, 23(11), 1367-1377 (2008-09-12)
The growing and indiscriminate use of high doses of anabolic androgenic steroid (AAS) among youth and athletes has raised serious concerns about its hepatotoxic effects. Herein, the influence of AAS in the nuclear phenotype of hepatocytes was investigated in sedentary

Metabolism: clinical and experimental, 48(5), 590-596 (1999-05-25)
We investigated whether the androgen type or application mode or testosterone (T) serum levels influence serum lipids and lipoprotein levels differentially in 55 hypogonadal men randomly assigned to the following treatment groups: mesterolone 100 mg orally daily ([MES] n =

Natural product research, 22(15), 1289-1296 (2008-11-22)
Microbial transformation of two anabolic steroids, ethylestrenol (1) and nandrolone (2), were carried out. Ethylestrenol (1), when incubated with Rhizopus stolonifer (TSY 0471), yielded two oxidative metabolites named 17alpha-ethyl-3beta,17beta-dihydroxy-19-norndrost-4-ene (3) and 17alpha-ethyl-17beta-hydroxy-19-norandrost-4-en-3-one (4), while incubation of compound 2 with the

Molecular endocrinology (Baltimore, Md.), 14(8), 1187-1197 (2000-08-10)
The androgen receptor (AR) is a ligand-dependent X-linked nuclear transcription factor regulating male sexual development and spermatogenesis. The receptor is activated when androgen binds to the C-terminal ligand-binding domain (LBD), triggering a cascade of molecular events, including interactions between the
