Project description:Spermatogenesis is a recurring differentiation process that results in the production of male gametes within the testes. During this process, spermatogonial stem cells differentiate to form spermatocytes, which undergo two rounds of meiotic division to form haploid spermatids. Throughout spermiogenesis, round spermatids elongate to form mature sperm. To profile changes in chromatin marks between spermatocytes and spermatids, we generated CUT&RUN data of H3K4me3, H3K27ac and H3K9me3 marks in sorted spermatocytes and spermatids.

Project description:Microarray analysis of purified pachytene spermatocytes and round spermatids. Each stage was examined in wild type and RNF8 knockout mice in two biological replicates. We performed microarray analysis using Affymetrix Gene 1.0 ST Arrays with purified pachytene spermatocytes and round spermatids. Pachytene spermatocytes and round spermatids were enriched from 3 to 4 males from the WT or Rnf8-KO via BSA gravity sedimentation according to the previous publication [PMID 8231890] and >95% (PS, RS) enrichments were verified after DAPI staining under a fluorescent microscope. For microarray analysis, total RNAs from purified pachytene spermatocytes or round spermatids were examined.

Project description:Introgressed variants from other species can be an important source of genetic variation because they may arise rapidly, can include multiple mutations on a single haplotype, and have often been pretested by selection in the species of origin. Although introgressed alleles are generally deleterious, several studies have reported introgression as the source of adaptive alleles-including the rodenticide-resistant variant of Vkorc1 that introgressed from Mus spretus into European populations of Mus musculus domesticus. Here, we conducted bidirectional genome scans to characterize introgressed regions into one wild population of M. spretus from Spain and three wild populations of M. m. domesticus from France, Germany, and Iran. Despite the fact that these species show considerable intrinsic postzygotic reproductive isolation, introgression was observed in all individuals, including in the M. musculus reference genome (GRCm38). Mus spretus individuals had a greater proportion of introgression compared with M. m. domesticus, and within M. m. domesticus, the proportion of introgression decreased with geographic distance from the area of sympatry. Introgression was observed on all autosomes for both species, but not on the X-chromosome in M. m. domesticus, consistent with known X-linked hybrid sterility and inviability genes that have been mapped to the M. spretus X-chromosome. Tract lengths were generally short with a few outliers of up to 2.7 Mb. Interestingly, the longest introgressed tracts were in olfactory receptor regions, and introgressed tracts were significantly enriched for olfactory receptor genes in both species, suggesting that introgression may be a source of functional novelty even between species with high barriers to gene flow.

Project description:Expression profiling of isolated populations of prepachytene spermatocytes (LP), pachytene spermatocytes (RP) and spermatids (ST) from PWD and B6 was performed to study the genome wide variation in gene expression between two mouse subspecies. To evaluate the transcriptional difference between B6 and PWD in during meiosis, we compared their transcriptomes in sorted populations of pre-pachytene primary spermatocytes (Leptonema, Zygotene and Pachytene), pachytene spermatocytes (Mid-late pachytene and diplotene) and spermatids.

Project description:Comparison of gene expression differences between Dnmt3L heterozygous and wildtype pachytene spermatocytes, and similarly between Dnmt3L heterozygous and wildtype round spermatids which were isolated from the Dnmt3L knockout mouse line. This array was conducted to address the hypothesis that Dnmt3L heterozygosity results in deregulated gene expression within spermatocytes and spermatids. Results show that Dnmt3L heterozygosity causes numerous genes to be differentially regulated on a genome-wide level, showing that DNMT3L has an important role in regulating gene expression within these male germ cells. Three preparations each of Dnmt3L purified wildtype spermatocytes, wildtype spermatids, heterozygous spermatids, and two preparations of heterozygous spermatocytes were isolated for a total of 11 samples. Each preparation was made up of cells isolated from 10 mice.
