A model for understanding gene regulation during spermatogenesis: the mouse testis Pdha-2 promoter

Abstract

Spermatogenesis is a complex process requiring the coordinate expression of a number of testis-specific genes. How these genes are regulated during spermatogenesis is poorly understood. However, the elucidation of these mechanisms has significant implications for both medicine and the primary livestock industry. The delineation of this process is of particular interest and, in this study, Pdha-2, a gene which codes for the murine testis-specific isoform of the E1 alpha subunit of the pyruvate dehydrogenase complex, has been used as a model. This review focuses on current knowledge about its expression and regulation during spermatogenesis.
