Leydig cells express the myelin proteolipid protein gene and incorporate a new alternatively spliced exon.

ABSTRACT: Although the myelin proteolipid protein gene (Plp1) is highly expressed in the central nervous system encoding the most abundant myelin protein in oligodendrocytes, it is also expressed in other tissues, including testis. Transgenic studies with mice that harbor Plp1-lacZ fusion genes suggest that Leydig cells are the source of Plp1 gene expression in testis. However, virtually nothing is known about Plp1 gene regulation in Leydig cells, which is the focus of this study. The first intron contains both positive and negative regulatory elements that are important in regulating Plp1 gene expression in oligodendrocytes. To test whether these elements are functional in Leydig cells, a battery of Plp1-lacZ fusion genes with partial deletion of Plp1 intron 1 sequence was transfected into the mous
