Research Abstract |
In order to examine androgen-signaling pathway in the epididymis, we have attempted to establish a conditional knock out mice of the androgen receptor gene in the initial segment of the epididymis. We first generated a transgenic mouse carrying a tamoxifen-regulated Cre recombinase gene driven by the epididymis-specific lipocalin gene promoter. When the mice was crossbred with a ROSA26-EGFP mice to confirm the Cre expression in the epididymis, unexpectedly the EGFP expression was recognized in the cauda epididymis. Although the Cre mice was crossbred with a mice carrying a conditional androgen receptor allele to generate a conditional androgen receptor knock out mice in the epididymis, the mice demonstrated a normal sperm concentration and mobility.
