| Abstract |
Spermatogenesis is regulated by many meiotic stage-specific genes, but how they coordinate the many individual processes is not fully understood. The Prss/Tessp gene cluster is located on mouse chromosome 9F2-F3, and the three genes at this site (Prss42/Tessp-2, Prss43/Tessp-3, and Prss44/Tessp-4) are specifically activated during meiosis in pachytene spermatocytes. We searched for DNase I hypersensitive sites (HSs) and long noncoding RNAs (lncRNAs) at the Prss/Tessp locus to elucidate how they are activated. We found eight DNase I HSs, three of which were testis germ cell-specific at or close to the Prss42/Tessp-2 promoter, and a testis-specific lncRNA, lncRNA-HSVIII, that was transcribed from a region adjacent to the Prss42/Tessp-2 gene. lncRNA-HSVIII transcripts localized to nuclei of most pachytene spermatocytes and the cytosol of stage-X pachytene spermatocytes and spermatids. Chromosome conformation capture revealed that the lncRNA-HSVIII locus specifically interacted with the Prss42/Tessp-2 promoter in primary and secondary spermatocytes. A 5.8-kb genome sequence, encompassing the entire lncRNA-HSVIII sequence and its flanking regions, significantly increased Prss42/Tessp-2 promoter activity using a reporter-gene assay, yet this construct did not change lncRNA-HSVIII expression, indicating that the elevated promoter activity was likely through enhancer activity. Indeed, both upstream and downstream regions of the lncRNA-HSVIII sequence significantly increased Prss42/Tessp-2 promoter activity. Our data therefore identified the direct interaction of a genomic region in the lncRNA-HSVIII locus with the Prss42/Tessp-2 promoter in spermatocytes, and suggested that sequences adjacent to the lncRNA function as enhancers for the Prss42/Tessp-2 gene.
