The miRNA profiling of goat CD49f-positive and negative testicular cells

ABSTRACT: Purpose: miRNAs, a member of the small RNA, play critical roles in the mammalian spermatogenesis. Spermatogonia was the foundation of spermatogenesis and valuable for the study of spermatogenesis. However, it is still not clear that the expression profiling of the miRNAs in spermatogonia of dairy goat. Methods: The CD49f was one of the surface markers for spermatogonia enrichment by MACS. Therefore, we used CD49f microbeads antibody to purify CD49f-positive and negative cells of dairy goat testicular cells by MACS (Magnetic Activated Cell Sorting), and then in-depth analyzed the miRNA expression in these cells using Illumina sequencing technology. Results: The results of miRNAs expression profiling in purified CD49f-positive and negative testicular cells showed that 933 were miRNAs upregulated in CD49f-positive cells and 916 were miRNAs upregulated in CD49f-negative cells with a 2-fold increase, respectively; some spermatogonial stem cells(SSCs) specific miRNAs and marker genes in testis had a higher level expression in CD49f-positive testicular cells, such as miR-221, miR-23a, miR-29b, miR-24, miR-29a, miR-199b, miR-199a, miR-27a, miR-21. Conclusions: our comparative miRNAome data provided some useful miRNAs profiling data of dairy goat spermatogonia cells and suggested CD49f could be used to enrich dairy goat spermatogonia-like cells, including SSCs. miRNA profiles of goat CD49f-positive and negative testicular cells were generated by deep sequencing, in triplicate, using Illumina GAIIx

Identification of type A spermatogonia specific transcriptome in rainbow trout immature testis

Project description:To identify the transcripts preferentially expressed in type A spermatogonia in rainbow trout immature testis, we compared the transcriptome between type A spermatogonia and testicular somatic cells by microarry analysis. We used fluorescence-activated cell sorting (FACS) to isolate type A spermatogonia or testicular somatic cells from the fishes carrying the transgene, pvasa-GFP, which expresses GFP in spermatogonia. RNA from type A spermatogonia and from testicular somatic cells were hybridized to a microarray after Cy3 labeling.

Discovery and Comparative Transcriptome Profiling of Dairy Goat MicroRNAs from Dry Period and Peak Lactation Mammary Gland Tissues

Project description:In this study, two small RNA libraries were constructed using dry period and peak lactation dairy goat mammary gland tissues and sequenced by the Illumina Solexa high-throughput sequencing system. A total of 346 conserved and 95 novel miRNAs were identified in the dairy goat. The expression of miRNAs was confirmed by qRT-PCR in nine tissues and the mammary gland during development cycles. In addition, several candidate miRNAs that may be involved in mammary gland development and lactation were found by the comparison of miRNA expression profiles among different tissue and developmental stages of the mammary gland. This study provides the identification and profile of miRNAs related to the biology of the mammary gland in the dairy goat. The identification of these miRNAs could contribute to understanding the molecular mechanisms of lactation physiology and the development of the mammary gland in the dairy goat.

Biomarkers in semen/urine from non-obstructive azoospermia patients to predict the presence of testicular spermatozoa and spermatogonia

Project description:About half of testicular sperm extraction (TESE) procedures in men with non-obstructive azoospermia (NOA), including men with Klinefelter syndrome (KS), are unsuccessful. To avoid unnecessary invasive surgery, biomarkers for spermatozoa have been studied and identified. In addition, markers for spermatogonia in testis tissue have been researched. This study aimed to find biomarkers in semen and/or urine of NOA patients to predict the presence of spermatogonia in the testis. This would especially be interesting for young boys. Differentially expressed miRNAs were identified (1) between samples from patients with and those of patients without a positive TESE procedure as well as (2) between TESE negative patients with and those without spermatogonia. A total of ten up-regulated miRNAs (seven in seminal plasma and three in urine) were found in the TESE-negative/spermatogonia-positive group compared to the TESE-negative/spermatogonia-negative group. These miRNAs could become biomarkers for spermatogonia, however, more research is necessary.

Transcriptional profiling of testicular biopsies with Sertoli-cell-only and spermatogonial presence

Project description:The aim of the study was to identify in vivo spermatogonial gene expression within the context of their biological niche. Identification of spermatogonial genes was done by t-testing on the replicates of Score 3 (Spermatogonia) and Score 2 (SCO) testicular biopsies. 3 biological replicates with spermatogonial presence in the tubuli seminiferi, 5 biological replicates with Sertoli-cell-only syndrome.
