Abstract

BACKGROUND: Androgens function through DNA and non-DNA binding-dependant signalling of the androgen receptor (AR). How androgens promote erythropoiesis is not fully understood. DESIGN AND METHODS: To identify the androgen signalling pathway, we treated male mice lacking the second zinc finger of the DNA binding domain of the AR (AR∆ZF2 ) with non-aromatizable 5α-dihydrotestosterone (5α-DHT), or aromatizable testosterone. To distinguish direct hematopoietic and non-hematopoietic mechanisms we performed bone marrow reconstitution experiments. RESULTS: In wild-type mice, 5α-DHT had greater erythroid activity than testosterone, which can be aromatized to estradiol. The erythroid response in wild..
