Androgen Receptors in Skeletal Muscle Cytosol From Sheep Treated With Trenbolone Acetate

Horm Metab Res. 1987 Mar;19(3):110-4. doi: 10.1055/s-2007-1011754.

Abstract

Female sheep were implanted with the anabolic agent trenbolone acetate and the effects of the treatment on the skeletal muscle androgen receptor studied. In two separate trials the binding capacity/mg skeletal muscle protein was reduced. In trial 1 the animals were implanted (80 mg trenbolone acetate) at the start and after 5 weeks of the trial and samples taken one week later while in the second trial samples were taken 15 days after a single implant (80 mg trenbolone acetate). The ability of a variety of steroids and steroid-like compounds to displace [3H] testosterone and [3H] methyltrienolone was also studied. The androgen receptor was also partially purified using heparin-sepharose chromatography The involvement of the anddrogen receptor in the mode of action of trenbolone is discussed.
