Gene expression in pachytene spermatocytes and round spermatids depleted of HDAC3

Project description:This study aims to explore the transcriptomic changes in Stra8-cre/Hdac3fl/- mice at meiotic and postmeiotic stages. Pachytene spermatocytes and round spermatids were isolated from testes of Hdac3fl/+ and Stra8-cre/Hdac3fl/- mice at 7-8 week-old through STA-PUT method. Cells from 6 WT mice or 10 Stra8-cre/Hdac3fl/- mice were pooled for one biological replicate. RNA-seq libraries were prepared in biological triplicates.

Changes of H3K9ac and H3K27ac recruitment in pachytene spermatocytes and round spermatids from testes-specific HDAC3-depleted mice and genome-wide maps of HDAC3,NCOR and Sox30 in wild-type and Sox30 KO testes

Project description:We reported changes in the recruitment of H3K9ac and H3K27ac in HDAC3-depleted mouse testes in the late meiotic and early haploid stages. We also investigated genome-wide occupancy of HDAC3, NCOR and Sox30 to the mouse testes from wild-type and Sox30 KO mice.

Effects of Fatty Acids on Intracellular [Ca2+], Mitochondrial Uncoupling and Apoptosis in Rat Pachytene Spermatocytes and Round Spermatids.

Project description:The aim of this work was to explore the ability of free arachidonic acid, palmitic acid and the unsaturated fatty acids oleic acid and docosahexaenoic acid to modify calcium homeostasis and mitochondrial function in rat pachytene spermatocytes and round spermatids. In contrast to palmitic acid, unsaturated fatty acids produced significant increases in intracellular calcium concentrations ([Ca2+]i) in both cell types. Increases were fatty acid specific, dose-dependent and different for each cell type. The arachidonic acid effects on [Ca2+]i were higher in spermatids than in spermatocytes and persisted when residual extracellular Ca2+ was chelated by EGTA, indicating that the increase in [Ca2+]i originated from release of intracellular calcium stores. At the concentrations required for these increases, unsaturated fatty acids produced no significant changes in the plasma membrane potential of or non-specific permeability in spermatogenic cells. For the case of arachidonic acid, the [Ca2+]i increases were not caused by its metabolic conversion to eicosanoids or anandamide; thus we attribute this effect to the fatty acid itself. As estimated with fluorescent probes, unsaturated fatty acids did not affect the intracellular pH but were able to induce a progressive decrease in the mitochondrial membrane potential. The association of this decrease with reduced reactive oxygen species (ROS) production strongly suggests that unsaturated fatty acids induced mitochondrial uncoupling. This effect was stronger in spermatids than in spermatocytes. As a late event, arachidonic acid induced caspase 3 activation in a dose-dependent manner both in the absence and presence of external Ca2+. The concurrent but differential effects of unsaturated fatty acids on [Ca2+]i and mitochondrial functions are additional manifestations of the metabolic changes that germ cells undergo during their differentiation.

Distinct Expression Profiles and Novel Targets of MicroRNAs in Human Spermatogonia, Pachytene Spermatocytes, and Round Spermatids between OA Patients and NOA Patients.

Project description:Human spermatogenesis includes three main stages, namely, the mitosis of spermatogonia, meiosis of spermatocytes, and spermiogenesis of spermatids, which are precisely regulated by epigenetic and genetic factors. Abnormality of epigenetic and genetic factors can result in aberrant spermatogenesis and eventual male infertility. However, epigenetic regulators in controlling each stage of normal and abnormal human spermatogenesis remain unknown. Here, we have revealed for the first time the distinct microRNA profiles in human spermatogonia, pachytene spermatocytes, and round spermatids between obstructive azoospermia (OA) patients and non-obstructive azoospermia (NOA) patients. Human spermatogonia, pachytene spermatocytes, and round spermatids from OA patients and NOA patients were isolated using STA-PUT velocity sedimentation and identified by numerous hallmarks for these cells. RNA deep sequencing showed that 396 microRNAs were differentially expressed in human spermatogonia between OA patients and NOA patients and 395 differentially expressed microRNAs were found in human pachytene spermatocytes between OA patients and NOA patients. Moreover, 378 microRNAs were differentially expressed in human round spermatids between OA patients and NOA patients. The differential expression of numerous microRNAs identified by RNA deep sequencing was verified by real-time PCR. Moreover, a number of novel targeting genes for microRNAs were predicted using various kinds of software and further verified by real-time PCR. This study thus sheds novel insights into epigenetic regulation of human normal spermatogenesis and the etiology of azoospermia, and it could offer new targets for molecular therapy to treat male infertility.

Comprehensive analysis of the transcriptome-wide m6A methylation in mouse pachytene spermatocytes and round spermatids

Project description:Spermatogenesis, an efficient and complex system in male germline development, requires a series of elaborately regulated genetic events in which diploid spermatogonia differentiate into haploid spermatozoa. N6-methyladenosine (m6A) is important for spermatogenesis. ALKBH5 is an m6A eraser, and knockout of ALKBH5 increases the level of total m6A methylation and causes male infertility.

Expression data of pachytene spermatocytes and round spermatids from young and aged Brown Norway rats

Project description:Male fertility and testis function changes with age and so it was sought to determine if these changes are accompanied by changes in gene expression. A full genome microarray was used to determine if distinct pathways of genes were altered in expression in germ cells (pachytene spermatocytes or round spermatids) with age.
