ABSTRACT: 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. Populations of pre-pachytene spermatocytes, pachytene spermatocytes and spermatids were isolated from PWD and B6 mice. All populations were isolated in duplicates from two animals. Hence, RNA was prepared from 12 samples (= 2 strains x 3 tissues x 2 replicas) and was then subject to labeling and hybridization on microarray chips.

Project description:MiRNA 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 miRNA expression between two mouse subspecies. Populations of pre-pachytene spermatocytes, pachytene spermatocytes and spermatids were isolated from PWD and B6 mice. All populations were isolated in triplicates from two bilogical replicas Hence, RNA was prepared from 18 samples and was then subject to labeling and hybridization on microarray chips.

Project description:The Mfn2 gene was conditionally knock-out from male mice germ cells using Stra8-Cre mice. The spermatocytes were collected from PD 24 and PD 52 male mice, and were further isolated as pachytene cells (P) and leptotene/zygotene cells (L/Z). The transcriptome between MFN2 WT and MFN2 cKO spermatocytes were analyzed via RNA-seq in P and L/Z populations at different ages, PD 24 amd PD 52, respectively.

Project description:Expression profiling of isolated populations of prepachytene spermatocytes, pachytene spermatocytes and spermatids of males carrying a translocation T(16;17)43H was performed to study the influence of this translocation on gene expression from individual chromosomes. To evaluate the transcriptional behavior of individual chromosomes in the sterile B10-T43/+ males and their fertile congenic B10-T43/T43 and B10 counterparts, we compared their transcriptomes in sorted populations of pre-pachytene primary spermatocytes, pachytene primary spermatocytes 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.
