ABSTRACT: To reveal distinct transcriptomes associated with various spermatogenic cells, including spermatogonial stem cells and all of their subsequent progeny, single-cell transcriptomes from Adult human spermatogonia, StaPut-enriched spermatocytes and spermatids, or unselected steady-state spermatogenic cells were used for Drop-Seq analysis. We used the 10x Genomics Chromium (Drop-Seq) to perform single-cell RNA-seq

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.

Heat stress induced piRNA alterations in pachytene spermatocytes and round spermatids.

Project description:BackgroundSpermatogenesis is a temperature-sensitive process, and elevation in temperature hampers this process quickly and significantly. We studied the molecular effects of testicular heating on piRNAs and gene expression in rat testicular germ cells.MethodsWe generated a cryptorchid rat model by displacing the testis from the scrotal sac (34 °C) to the abdominal area (37 °C) and sacrificed animals after 1 day, 3 days, and 5 days. Pachytene spermatocytes and round spermatids were purified using elutriation centrifugation and percoll gradient methods. We performed transcriptome sequencing in pachytene spermatocytes and round spermatids to identify differentially expressed piRNAs and their probable targets, i.e., TE transcripts and mRNAs.ResultsAs a result of heat stress, we observed significant upregulation of piRNAs and TE transcripts in testicular germ cells. In addition to this, piRNA biogenesis machinery and heat shock proteins (Hsp70 and Hsp90 family members) were upregulated. mRNAs have also been proposed as targets for piRNAs; therefore, we shortlisted certain piRNA-mRNA pairs with an inverse relationship of expression. We observed that in testicular heat stress, the heat shock proteins go hand-in-hand with the upregulation of piRNA biogenesis machinery. The dysregulation of piRNAs in heat-stressed germ cells, increased ping-pong activity, and disturbed expression of piRNA target transcripts suggest a connection between piRNAs, mRNAs, and TE transcripts.ConclusionsIn heat stress, piRNAs, piRNA machinery, and heat shock proteins are activated to deal with low levels of stress, which is followed by a rescue approach in prolonged stressaccompained by high TE activity to allow genetic mutations, perhaps for survival and adaptability.

A new dataset of spermatogenic vs oogenic transcriptomes in the nematode C. elegans

Project description:The nematode Caenorhabditis elegans is an important model for studies of germ cell biology, including specification as sperm or oocyte, the meiotic cell cycle and gamete differentiation. Fundamental to those studies is a genome-level knowledge of the germline transcriptome. Here we use RNA-Seq to identify genes expressed in isolated XX gonads, which are roughly 95% germline and 5% somatic gonadal tissue. We generate data from mutants making either sperm [fem-3(q96)] or oocytes (fog-2), both grown at 22M-BM-0C. Our dataset identifies a total of 10,754 mRNAs in the polyadenylated transcriptome of XX gonads, with 1,723 enriched in spermatogenic gonads, 2,869 enriched in oogenic gonads and the remaining 6,274 not enriched in either. These spermatogenic, oogenic and gender-neutral gene datasets compare well with those of earlier studies, but double the number of genes identified. We also query our RNA-Seq data for differential exon usage and find 351 mRNAs with sex-specific isoforms. We suggest that this new dataset will prove useful for studies focusing on C. elegans germ cell biology. Comparison of spermatogenic vs oogenic transcriptomes

Changes in Expressions of Spermatogenic Marker Genes and Spermatogenic Cell Population Caused by Stress

Project description:Purpose: Many young adults are in a state of stress due to social and psychological pressures, which may result in male reproductive dysfunction. To provide new insight into this phenomenon, we investigated the relationship between pathological changes in rat spermatogenic cells and the expression of genes specific to spermatogenic cell types under different stress conditions. Methods: After establishing rat stress models of different time durations, we observed pathological changes in testicular tissues through haematoxylin and eosin staining, and analysed gene expression in spermatogenic cells by RNA-seq, bioinformatic analysis, and reverse transcription qPCR (RT-qPCR).Three testicular samples were taken from each group to construct 12 cDNA libraries. For each sample, 3 μg RNA was used as the starting material. Ribosomal RNA was removed using the Epicentre Ribo-Zero™ Gold kit (Rat) (Epicentre, an Illumina company, Madison, WI, USA). Results:Compared with the control group, there were 1,194 DEGs in the 3-day RS+IS group , including 455 upregulated genes and 739 downregulated genes , 1,774 DEGs in the 14-day RS+IS group including 1,124 upregulated genes and 650 downregulated genes, and 2,267 DEGs in the 21-day RS+IS group including 1,366 upregulated genes and 901 downregulated genes. Mean-while, some same expression patterns were observed in three phenotypes.After comparison with single-cell sequencing data, 349 DEGs of spermatogenic cells at different developmental stages were found. Conclusions: Our study suggest that chronic psychosomatic stress can affect the spermatogenic transcriptome of the testes, leading to a significant change in the expression of the spermatogenic genes. At the same time, histopathological and immunohistochemical results showed that chronic stress may lead to pathological changes in spermatogenic cells and to a significant decrease in key regulatory proteins
