Abstract
The estrogen receptor-alpha knockout (ERalphaKO, ERalpha-/-) mice were generated via the Cre-loxP system by mating floxed ERalpha mice with beta-actin (ACTB)-Cre mice. The impact of ERalpha gene deletion in the male reproductive system was investigated. The ACTB-Cre/ERalpha(-/-) male mice are infertile and have lost 90% of epididymal sperm when compared with wild-type mice. Serum testosterone levels in ACTB-Cre/ERalpha(-/-) male mice are 2-fold elevated. The ACTB-Cre/ERalpha(-/-) testes consist of atrophic and degenerating seminiferous tubules with less cellularity in the disorganized seminiferous epithelia. Furthermore, the ventral and dorsal-lateral prostates of ACTB-Cre/ERalpha(-/-) mice display reduced branching morphogenesis. Loss of ERalpha could also be responsible for the decreased fibroblast proliferation and changes in the stromal content. In addition, we found bone morphogenetic protein, a mesenchymal inhibitor of prostatic branching morphogenesis, is significantly up-regulated in the ACTB-Cre/ERalpha(-/-) prostates. Collectively, these results suggest that ERalpha is required for male fertility, acts through a paracrine mechanism to regulate prostatic branching morphogenesis, and is involved in the proliferation and differentiation of prostatic stromal compartment.

Our laboratory is interested in understanding the molecular and genetic events underlying cancer progression and metastasis. The focus of our work is a series of genetically engineered mouse models that faithfully recapitulate human disease. Using a combination of mouse genetics, omics technologies, cross-species analyses and in vitro approaches, we aim to identify cancer cell–intrinsic and –extrinsic mechanisms driving metastatic cancer progression, with a long
