(Submitter supplied) Studies of mice with Y chromosome long arm deficiencies suggest that the male-specific region (MSYq) encodes information required for sperm differentiation and postmeiotic sex chromatin repression (PSCR). Several genes have been identified on MSYq, but because they are present in more than 40 copies each, their functions cannot be investigated using traditional gene targeting. Here, we generate transgenic mice producing small interfering RNAs that specifically target the transcripts of the MSYq-encoded multicopy gene Sly (Sycp3-like Y-linked). more...

(Submitter supplied) The Y-encoded multicopy gene Sly has been shown to repress X and Y genes in spermatids, among which are its X-linked homologs Slx and Slxl1, via modulation of post-meiotic sex chromain (PMSC). In this experiment, we compared expression in spermatids from mice that are deficient for Sly (shSLY), for Slx/Slxl1 (shSLX1) or both (shSLX1shSLY). We observed that Slx/Slxl1 has an opposite role to that of Sly, and stimulates expression of X and Y genes in spermatids when Sly is absent. more...

(Submitter supplied) The gene Sly is present in multiple copies on the mouse Y chromosome and encodes a protein that is required for the epigenetic regulation of postmeiotic sex chromosome expression. The X chromosome carries two multicopy genes related to Sly: Slx and Slxl1. Here we investigate the role of Slx/Slxl1 using transgenically-delivered small interfering RNAs to disrupt their function. We show that Slx and Slxl1 are important for normal sperm differentiation and male fertility. more...

(Submitter supplied) Mapping of in vivo targets for HSF2 by using mammalian tissue material in a global ChIP-chip promoter screen. Chromatin was isolated from three wild-type (WT) mouse testes, crosslinked and sonicated into fragments of 100-500 bp, and the quality of the DNA was controlled before the immunoprecipitation, showing no signs of degradation. The DNA amplified from the HSF2 immunoprecipitation samples was labeled and hybridized against the total input DNA samples, on a 1.5 kb promoter tiling array (NimbleGen Systems Inc.), covering ~26000 promoters of the mouse genome. more...

(Submitter supplied) Background: The ubiquitin-conjugating enzyme HR6B is required for spermatogenesis in mouse. Loss of HR6B results in aberrant histone modification patterns on the trancriptionally silenced X and Y chromosomes (XY body) and on centromeric chromatin in meiotic prophase. We studied the relationship between these chromatin modifications and their effects on global gene expression patterns, in spermatocytes and spermatids. more...

(Submitter supplied) In mammals, the X and Y chromosomes are subject to meiotic sex chromosome inactivation (MSCI) during prophase I in the male germline, but their status thereafter is currently unclear. An abundance of X-linked spermatogenesis genes has spawned the view that the X must be active [1-8]. On the other hand, the idea that the imprinted paternal X of the early embryo may be pre-inactivated by MSCI suggests that silencing may persist longer [9-12]. more...

Analysis of four spermatic subpopulations: type A and type B spermatogonia, pachytene spermatocytes, and round spermatids. The X and Y chromosomes are subject to meiotic sex chromosome inactivation in the mammalian male germline. Results provide insight into the extent of postmeiotic X silencing.

(Submitter supplied) Deletion of multicopy genes located in the male-specific region of the mouse Y chromosome long arm (MSYq) is associated with sperm head abnormalities and male infertility. Heat shock factor 2 (HSF2) regulates the transcription of multicopy genes in MSYq. Little is known how HSF2-dependent regulation of the MSYq genes occurs only in testis. Testis harbors the largest number of tissue-specific long noncoding RNAs (lncRNAs). more...

(Submitter supplied) Purpose: This study was carried out to determine the consequences of the Rfx2-/- genotype on spermatogenesis in the mouse Methods: RNA was extracted from decapsulated testes of 21 day old mixed background mice of either genotype. Deep sequencing was used to determine quantitative expression of the genomes from independent replicates of each genotype Results: RNA-Seq analysis identified some 105 genes that are down regulated at least 2-fold in Rfx2-/- testes, with ~50 being reduced at least 10-fold Conclusion: Spermatogenesis undergoes complete arrest just prior to the end of the round spermatid period of sperm development in mutant mice. more...
