Differential miroRNA expression in round spermatids of GRTH null mice compared to wild type.

Project description:miRNA expression profiles for round spermatids of wild type and GRTH knock-out mice were determined by Rodent TaqMan® Low Density miRNA Arrays A v2.0 (TLDA, Applied Biosystem). Purified round spermatids were prepared from the testis of wild type and GRTH null mice (C57BL/6 strain). Equal amount of total RNA from 20 mice (wild type or GRTH KO) was pooled prior to gene expression analysis.

The miRNA expression profiles of round spermatids during GRTH/DDX25 mediated spermiogenesis: mRNA-miRNA Network analysis [miRNAseq]

Project description:GRTH/DDX 25 is a member of the DEAD-box family of RNA helicases that play an essential role in spermatogenesis. Regulation of spermatogenesis occurs at the levels of transcription, post-transcriptional and translational levels which needs to be explored in detail. miRNAs regulate the expression of important genes involved in spermatid elongation process. Differential miRNA expression in round spermatids (RS) of GRTH KO and GRTH-KI mice in comparison with mRNAs remains unexplored. Our miRNAseq analysis of small RNAs obtained from RS reveal differential expression of important miRNAs that regulate spermatid differentiation, apoptosis, chromatin compaction and ubiquitination. mRNAseq analysis of RS isolated from GRTH-KI and GRTH-KO mice models were also carried-out to study the putative miRNA targets and mRNA-miRNA interaction. mRNAseq analysis revealed specific set of mRNAs that are critical for sperm chromatin compaction, ubiquitination and spermatid elongation etc. miRNA-mRNA interaction prediction highlighted differentially expressed/enriched miRNA transcripts whose predicted mRNA targets were differentially expressed. Based on the interaction information of the miRNAs-mRNAs differential analysis, the miRNA-mRNA network was constructed. These results demonstrate the importance of miRNA in the translational arrest and stability of germ cell specific mRNAs which are critical for later stages of spermiogenesis and fertility.

Expression data from purified control and BrdtΔBD1 round spermatids.

Project description:Brdt is a testis specific member of a family of chromatin interacting proteins. All of the family members have been shown to regulate transcription. Brdt is highly expressed in round spermatids, and may play a role in transcriptional regulation in these cells. We investigated transcriptional changes in mutant round spermatids that were homozygous for a mutation in which the first bromodomain of Brdt was removed. Round spermatids were purified from seven adult animals of each genotype for each Affymetrix microarray. Purity of round spermatids was assessed by propidium iodide staining.

Expression data from E12.5 male fatal PGCs, PGCLC in vitro, round spermatids and spermatids like cells produced in vitro

Project description:Generation of haploid gametes in vitro can potentially address gamete failure-based infertility.This study reports complete in vitro meiosis from murine ESC-derived PGCLCs resulting in the formation of male spermatid-like cells (SLCs) capable of producing viable fertile offspring via intracytoplasmic sperm injection (ICSI).Our findings provide the basis for generation of haploid spermatids in vitro in human, the generation of transgenic animals, and the use of this system to investigate mechanisms of meiosis. We used microarrays to compare gene expression profiles of in vivo and in vitro derived PGC cells and round spermatids. We collected E12.5 male fatal PGCs, PGCLC in vitro, round spermatids and spermatids like cells produced in vitro, each sample has 3 replications.
