Microarray analysis of purified germ cells in mouse

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.

Gene expression profiling in male rat germ cells after chronic cyclophosphamide treatment

Project description:To further understand the effects of chronic cyclophosphamide treatment on spermatogenesis, we used whole genome microarrays to identify differentially expressed genes in pachytene spermatocytes and round spermatids from treated and control male rats. Pachytene spermatocytes and round spermatids from rats treated chronically with cyclophosphamide were isolated and profiled for changes in gene expression.

MicroRNA profiling in male rat germ cells after chronic cyclophosphamide treatment

Project description:Although numerous miRNAs have been identified in the testis, their roles in regulating the highly specific events that occur in the different germ cell types throughout spermatogenesis remain largely unknown. Furthermore, whether male germ cell miRNA expression is altered in response to or as a consequence of exposure to a toxic agent is unknown. Here we examine miRNA expression profiles in pachytene spermatocytes and round spermatids obtained from control rats and from rats treated with a chronic low dose of cyclophosphamide, a male germ cell toxicant. We observed that pachytene spermatocytes and round spermatids display vastly different miRNA expression profiles, reflecting their different developmental stages and possibly influencing the cellular response to toxic insult. Chronic low dose cyclophosphamide treatment altered the miRNA profiles in both pachytene spermatocytes and round spermatids. Target prediction analyses revealed that miRNAs altered by cyclophosphamide treatment may be involved in the response to cellular stress and damage. However, many are also involved in processes that are crucial for proper germ cell development. This study suggests that pachytene spermatocytes and round spermatids display distinct miRNA profiles that can be altered by cyclophosphamide treatment. The observed changes may be part of a response and repair mechanism to cyclophosphamide-induced damage or a dysregulation that disrupts normal germ cell development.

miRNA expression profiling of enriched male germ cell populations

Project description:MicroRNA is essential for the process of spermatogonesis, however analysis of its change in expression within germ cells during this process has been limited. We set out to examine the change in the miRNA expression profile of highly enriched mouse germ cell populations in vairous developmental stages.These inlcuded postnatal gonocytes, day 7-9 spermatogonia as well as pachytene spermatocytes and round spermatids from adult mice Gonocytes (day1) and spermatogonia (day 7-9), pachytene spermatocytes and round spermadits (adult) were enrichged by 2-4% BSA gradient sedementation. Three biological replicates of each cell type were included.

H3K27 acetylation and gene expression during late spermatogenesis

Project description:ChIP-seq for H3K27 acetylation and RNA-seq were performed during spermatogenesis. We analyzed two representative stages of spermatogenesis: purified pachytene spermatocytes (PS) undergoing meiosis; and postmeiotic round spermatids (RS) from adult testes.
