| Outline of Final Research Achievements |
We have looked to see if in vivo gene transfer into the testis could be used to study the pattern of localization of sperm protein phospholipase C zeta (PLCζ). We employed a vector designed to produce a fusion of full length clone of mouse PLCζand the enhanced yellow fluorescent protein (EYFP).Male mice (4-6 weeks of age) were used for in vivo experiments. For each animal, the right testis was exposed and the PLCζ-EYFP injected into the rete testis via the efferent duct. An electrical current was subsequently applied to the right testis whilst the left testis was left completely untouched throughout the procedure to act as a control.
We detected EYFP fluorescence in the epididymal sperm at 40 days after the procedure. The expression of EYFP was evident predominantly in the sperm head in their mid-pieces. Our results suggest that this approach could have great relevance for the study of sperm function and male infertility.
