Abstract
Around 50% of all occurrences of infertility are attributable to the male factor, which is a significant global public health concern. There are numerous circumstances that might interfere with spermatogenesis and cause the body to produce abnormal sperm. While evaluating sperm, the count, the speed at which they migrate, and their appearance are the three primary characteristics that are analyzed. MicroRNAs, also known as miRNAs, are present in all physiological fluids and tissues. They participate in both physiological and pathological processes. Researches have demonstrated that the expression of microRNA genes differs in infertile men. These genes regulate spermatogenesis at various stages and in several male reproductive cells. Hence, microRNAs have the potential to act as useful indicators in the diagnosis and treatment of male infertility and other diseases affecting male reproduction. Despite this, additional research is necessary to determine the precise miRNA regulation mechanisms.

Abstract
Infertility affects approximately 10-15% of couples worldwide who are attempting to conceive, with male infertility accounting for 50% of infertility cases. Male infertility is related to various factors such as hormone imbalance, urogenital diseases, environmental factors, and genetic factors. Owing to its relationship with genetic factors, male infertility cannot be diagnosed through routine examination in most cases, and is clinically called 'idiopathic male infertility.' Recent studies have provided evidence that microRNAs (miRNAs) are expressed in a cell-or stage-specific manner during spermatogenesis. This review focuses on the role of miRNAs in male infertility and spermatogenesis. Data were collected from published studies that investigated the effects of miRNAs on spermatogenesis, sperm quality and quantity, fertilization, embryo development, and assisted reproductive technology (ART) outcomes. Based on the findings of these studies, we summarize the targets of miRNAs and the resulting functional effects that occur due to changes in miRNA expression at various stages of spermatogenesis, including undifferentiated and differentiating spermatogonia, spermatocytes, spermatids, and Sertoli cells (SCs). In addition, we discuss potential markers for diagnosing male infertility and predicting the varicocele grade, surgical outcomes, ART outcomes, and sperm retrieval rates in patients with non-obstructive azoospermia (NOA).

Abstract
Male germline stem cells (mGSCs), also known as spermatogonial stem cells (SSCs), are the fundamental seed cells of male animal reproductive physiology. However, environmental influences, drugs, and harmful substances often pose challenges to SSCs, such as population reduction and quality decline. With advancements in bioengineering technology and biomaterial technology, an increasing number of novel cell culture methods and techniques have been employed for studying the proliferation and differentiation of SSCs in vitro. This paper provides a review on recent progress in 3D culture techniques for SSCs in vitro; we summarize the microenvironment of SSCs and spermatocyte development, with a focus on scaffold-based culture methods and 3D printing cell culture techniques for SSCs. Additionally, decellularized testicular matrix (DTM) and other biological substrates are utilized through various combinations and approaches to construct an in vitro culture microenvironment suitable for SSC growth. Finally, we present some perspectives on current research trends and potential opportunities within three areas: the 3D printing niche environment, alternative options to DTM utilization, and advancement of the in vitro SSC culture technology system.

Abstract
MicroRNAs (miRNAs), as post-transcriptional gene mediators, regulate the biological characteristics of spermatogonial stem cells (SSCs), including proliferation, differentiation and apoptosis. However, the potential roles and mechanisms by which miR-101-5p affected the biological characters of goat SSCs have not been fully elucidated. Herein, we reported that miR-101-5p overexpression decreased cell viability (P < 0.01), arrested cell cycle in the G1 phase (P < 0.05), and aggravated apoptosis of goat SSCs (P < 0.01) compared with negative control (NC), as determined by CCK-8 assay and flow cytometry analysis. Additionally, PCNA protein expression was attenuated by miR-101-5p overexpression (P < 0.05). Notably, the expression of SSCs specific genes Oct4 (P < 0.05), PLZF (P < 0.01) and DAZL (P < 0.01) were decreased in miR-101-5p overexpressed SSCs. Furthermore, the dual luciferase reporter assay showed that, when co-transfected with miR-101-5p mimics, the relative luciferase activity of EZH2 wide-type (WT) was inhibited (P < 0.05) compared with the transfection of EZH2 mutant (MUT). EZH2 expression was negatively correlated with miR-101-5p expression in goat SSCs. Collectively, our data implicates that miR-101-5p overexpression aggravates cell apoptosis, and suppresses cell proliferation of goat SSCs via targeting EZH2, which may impair spermatogenesis.

Abstract
The aim of the study was to perform the first in-depth analysis of miRNAs in ovarian and testicular tissues of the domestic cat, a critical biomedical model. Specifically, potential miRNA involvement was explored in gonadal function, testis development, and cellular stress response to preservation protocols. We performed miRNA-sequencing on 20 ovarian and 20 testicular samples from 15 cats, including different ages and tissue treatments. Using fresh tissues (n = 15), we confirmed gonadal expression of 183 miRNA precursors and discovered additional 52 novel feline candidate precursors. We integrated the mRNA data from our previous study on the same age and treatment groups to create in-silico miRNA-mRNA networks and their functional enrichment, which allows comprehensive exploration into possible miRNA functions in cat gonads. Clusters of miRNAs united by shared differentially expressed mRNA targets are potentially involved in testicular development and spermatogenesis. MicroRNAs could play a significant role in ovarian tissue response to stress from microwave-assisted dehydration, with smaller roles in cellular response to vitrification in both ovary and testis. This new list of miRNAs with potential function in cat gonads is a major step towards understanding the gonadal biology, as well as optimizing fertility preservation protocols.

Abstract
Spermatogenesis directly determines the reproductive capacity of male animals. With the development of society, the increasing pressure on people’s lives and changes in the living environment, male fertility is declining. The leaf of Eucommia ulmoides Oliv. (Eucommiae Folium, EF) was recorded in the 2020 Chinese Pharmacopoeia and was used in traditional Chinese medicine as a tonic. In recent years, EF has been reported to improve spermatogenesis, but the mechanisms of EF remain was poorly characterized. In this study, the effect of EF ethanol extract (EFEE) on spermatogenesis was tested in mice. Chemical components related to spermatogenesis in EF were predicted by network pharmacology. The biological activity of the predicted chemical components was measured by the proliferation of C18-4 spermatogonial stem cells (SSCs) and the testosterone secretion of TM3 leydig cells. The biological activity of chlorogenic acid (CGA), the active compound in EF, was tested in vivo. The cell cycle was analysed by flow cytometry. Testosterone secretion was detected by ELISA. RNA interference (RNAi) was used to detect the effect of key genes on cell biological activity. Western blotting, qRT–PCR and immunofluorescence staining were used to analyse the molecular mechanism of related biological activities. The results showed that EFEE and CGA could improve spermatogenesis in mice. Furthermore, the main mechanism was that CGA promoted SSC proliferation, self-renewal and Leydig cell testosterone secretion by promoting the expression of SHP2 and activating the downstream signaling pathways involved in these biological processes. This study provided strong evidence for elucidating the mechanism by which EF promotes the spermatogenesis in mice and a new theoretical basis for dealing with the decrease in male reproductive capacity.

Abstract
The World Health Organization predicts that infertility will be the third major health threat after cancer and cardiovascular disease, and will become a hot topic in medical research. Studies have shown that epigenetic changes are an important component of gametogenesis and related reproductive diseases. Epigenetic regulation of noncoding RNA (ncRNA) is appropriate and is a research hotspot in the biomedical field; these include long noncoding RNA (lncRNA), microRNA (miRNA), and PIWI-interacting RNA (piRNA). As vital members of the intracellular gene regulatory network, they affect various life activities of cells. LncRNA functions as a molecular bait, molecular signal and molecular scaffold in the body through molecular guidance. miRNAs are critical regulators of gene expression; they mainly control the stability or translation of their target mRNA after transcription. piRNA functions mainly through silencing genomic transposable elements and the post-transcriptional regulation of mRNAs in animal germ cells. Current studies have shown that these ncRNAs also play significant roles in the reproductive system and are involved in the regulation of essential cellular events in spermatogenesis and follicular development. The abnormal expression of ncRNA is closely linked to testicular germ cell tumors, poly cystic ovary syndrome and other diseases. This paper briefly presents the research on the reproductive process and reproductive diseases involving ncRNAs.

Abstract
Submandibular glands (SMGs) are one of the primary components of salivary glands in goats. The proteins and biologically active substances secreted by the SMGs change with growth and development. Our previous studies showed that most of the differentially expressed genes in the SMGs of goats at different developmental stages are involved in immune-related signaling pathways, but the miRNA expression patterns in the same tissues are unknown. The aim of this study was to reveal the expression profile of miRNAs at three different developmental stages, detect differentially expressed miRNAs (DE miRNAs) and predict disease-related DE miRNAs. SMG tissue samples were collected from groups of 1-month-old kids, 12-month-old maiden goats and 24-month-old adult goats (three samples from each group), and high-throughout transcriptome sequencing was conducted. A total of 178, 241 and 7 DE miRNAs were discovered between 1-month-old kids and 12-month-old maiden goats, between 1-month-old kids and 24-month-old adult goats, and between 12-month-old maiden goats and 24-month-old adult goats, respectively. Among these DE miRNAs, 88 DE miRNAs with medium or high expression levels (TPM ≥50) were classified into five expression pattern clusters. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses indicated that some of the predicted target genes of the DE miRNAs in the five clusters were enriched in disease-related GO terms and pathways. MiRNA target genes in significant pathways were significantly enriched in Hepatitis B (FDR = 9.03E-10) and Pathways in cancer (FDR = 4.2E-10). Further analysis was performed with a PPI network, and 10 miRNAs were predicted to play an important role in the occurrence and prevention of diseases during the growth and development of goats.

Abstract
The non-coding genome has been extensively studied for its role in human development and diseases. MicroRNAs (miRNAs) are small non-coding RNAs, which can regulate the expression of hundreds of genes at the post-transcriptional level. Therefore, any defects in miRNA biogenesis or processing can affect the genes and have been linked to several diseases. Male infertility is a clinical disorder with a significant number of cases being idiopathic. Problems in spermatogenesis and epididymal maturation, testicular development, sperm maturation or migration contribute to male infertility, and many of these idiopathic cases are related to issues with the miRNAs which tightly regulate these processes. This review summarizes the recent research on various such miRNAs and puts together the candidate miRNAs that may be used as biomarkers for diagnosis. The development of strategies for male infertility treatment using anti-miRs or miRNA mimics is also discussed. Although promising, the development of miRNA diagnostics and therapeutics is challenging, and ways to overcome some of these challenges are also reviewed.

Evaluation of The Relationship among The Levels of SIRT1 and SIRT3 with Oxidative Stress and DNA Fragmentation in Asthenoteratozoospermic Men. INTERNATIONAL JOURNAL OF FERTILITY & STERILITY 2021; 15:135-140. [PMID: 33687167 PMCID: PMC8052804 DOI: 10.22074/ijfs.2020.134692] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/11/2020] [Accepted: 10/19/2020] [Indexed: 12/03/2022]
Abstract
Background Reactive oxygen species (ROS) play a crucial role in etiology of DNA fragmentation and lipid peroxi-
dation in sperm, leading to infertility in men. The silent information regulators SIRT1 and SIRT3 are members of the
sirtuins protein family known to be involved in cancer genetics, aging and oxidative stress responses. The aim ofthis
study is to determine the correlation between SIRT1 and SIRT3 with antioxidants, oxidative stress biomarkers, and
DNA fragmentation in the semen of asthenoteratozoospermic and normozoospermic men. Materials and Methods In this case-control study, after spermogram analysis the specimens were divided into
two groups, normozospermic (n=40) and asthenoteratozoospermic (n=40), according to World Health Organization
(WHO) standards. Sperm DNA fragmentation was evaluatedusing the sperm chromatin dispersion (SCD) test.Catalase
activity was measured using the Aebi spectrophotometeric method. Total antioxidant capacity (TAC) level and super-
oxide dismutase (SOD) activitywere measured by using commercially available colorimetric assays. Enzyme-linked
immune sorbent assay (ELISA) was used to measure SIRT1 and SIRT3 protein levels of seminal plasma. Malondial-
dehyde (MDA) level in seminal plasma was determined by high-performance liquid chromatography (HPLC). Results The asthenoteratozoospermic group had significantly lower catalase and SOD activities and TAC levels in
comparison with the normozoospermic group (P<0.001).The percentage of DNA fragmentation and MDA level in the
asthenoteratozoospermic group were remarkably higher than in the normozoospermic group. The SIRT1 and SIRT3
protein levels in seminal plasmawere remarkably lower in asthenoteratozoospermic group than the normozoospermic
group (P<0.001). Conclusion The results of this study suggest that SIRT1 and SIRT3 protein levels are negatively correlated with
oxidative stress and DNA fragmentation in semen. The low levels of SIRT1 and SIRT3 in asthenoteratozoospermic
men may lead to an increase in oxidative stress, DNA fragmentation, and lipid peroxidation that eventually result in
immotile and immature spermatozoa (asthenoteratozoospermia).

MiR-182-5p, MiR-192-5p, and MiR-493-5p Constitute a Regulatory Network with CRISP3 in Seminal Plasma Fluid of Teratozoospermia Patients. Reprod Sci 2021; 28:2060-2069. [PMID: 33620707 DOI: 10.1007/s43032-021-00485-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Accepted: 01/31/2021] [Indexed: 10/22/2022]
Abstract
Numerous evidences suggested that microRNAs (miRs) could play an active and significant role during spermatogenesis. Cysteine-rich secretory protein (CRISP3) has a role in inflammatory response and is extremely over-expressed in adolescents with varicocele seminal plasma and modified semen analysis. Nowadays, the miRs expression's association with their target genes is well recognized. The aim of this study was evaluating the association of CRISP3 and four candidate miRs among teratozoospermia (TZ) infertile men. First, we have selected four miRs, miR-182-5p, miR-192-5p, miR-204-5p, and miR-493-5p bioinformatically. After that, RNA was extracted from semen samples of 21 TZ patients and 20 normozoospermia (Norm). Then, their expression levels were assessed using real-time polymerase chain reaction method. In the next step, we quantified the expression of two CRISP3 protein isoforms, targeted by these miRs, using western blotting. According to our results, up-regulation of miR-182-5p, miR-192-5p, and miR-493-5p was observed. MiR-182-5p, miR-192-5p, and miR-493-5p showed good AUC values which can be introduced as possible biomarkers of TZ. In addition, the expression level of the CRISP3 glycosylated (31 kDa) isoform was significantly lower in TZ patients than Norm ones. Notably, in TZ patients, there was a possibly positive correlation of glycosylated CRISP3 expression with normal sperm morphology. According to our results, CRISP3 protein can play a significant role in male infertility especially in maturation formation of spermatozoa. Also, deregulation of the studied miRs, miR-182-5p, miR-92-5p, and miR-493-5p, can suggest a regulatory network between these miRs and CRISP3 isoforms and suggest their regulatory roles in male infertility.

MiR-204-5p promotes lipid synthesis in mammary epithelial cells by targeting SIRT1. Biochem Biophys Res Commun 2020; 533:1490-1496. [PMID: 33333715 DOI: 10.1016/j.bbrc.2020.10.056] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2020] [Accepted: 10/20/2020] [Indexed: 12/21/2022]
Abstract
OBJECTIVES Understanding the molecular mechanisms of lipid synthesis in the mammary gland is crucial for regulating the level and composition of lipids in milk. This study aimed to investigate the functional and molecular mechanisms of miR-204-5p in mammary epithelial cells to provide a theoretical basis for milk lipid synthesis. METHODS Real-time quantitative PCR was performed to detect the transcriptional levels of miR-204-5p and related mRNA abundance in mammary epithelial cells. Western blotting was conducted to determine protein expression. Cell proliferation was assessed by Cell Counting Kit-8. A dual-luciferase reporter assay was conducted to verify the targeting relationship between miR-204-5p and SIRT1. siRNA and overexpression plasmids were transfected into mouse HC11 mammary epithelial cells. RESULTS The abundance of miR-204-5p was much higher in lactating mouse mammary glands than in other tissues, which indicated that miR-204-5p may be involved in regulating milk production. MiR-204-5p affected the expression of β-casein and milk lipid synthesis in HC11 mouse mammary epithelial cells but did not influence the proliferation of HC11 cells. Overexpression of miR-204-5p significantly increased the number of Oil Red O+ cells, triglyceride accumulation and the expression of markers associated with lipid synthesis, including FASN and PPARγ, whereas inhibition of miR-204-5p had the opposite effect. miR-204-5p promotes lipid synthesis by negatively regulating SIRT1. Overexpression of SIRT1 can repress the promotion of miR-204-5p on lipid synthesis. CONCLUSION Our findings showed that miR-204-5p can promote the synthesis of milk lipids in mammary epithelial cells by targeting SIRT1.

Abstract
Spermatogenesis is a complex process that originates from and depends on the spermatogonial stem cells (SSCs). The number of SSCs is rare, which makes the separation and enrichment of SSCs difficult and inefficient. The transcription factor PAX7 maintains fertility in normal spermatogenesis in mice. However, for large animals, much less is known about the SSCs' self-renewal regulation, especially in dairy goats. We isolated and enriched the CD49f-positive and negative dairy goat testicular cells by magnetic-activated cell sorting strategies. The RNA- sequencing and experimental data revealed that cells with a high CD49f and PAX7 expression are undifferentiated spermatogonia in goat testis. Our findings indicated that ZBTB16 (PLZF), PAX7, LIN28A, BMPR1B, FGFR1, and FOXO1 were expressed higher in CD49f-positive cells as compared to negative cells and goat fibroblasts cells. The expression and distribution of PAX7 in dairy goat also have been detected, which gradually decreased in testis tissue along with the increasing age. When the PAX7 gene was overexpressed in dairy goat immortal mGSCs-I-SB germ cell lines, the expression of PLZF, GFRα1, ID4, and OCT4 was upregulated. Together, our data demonstrated that there is a subset of spermatogonial stem cells with a high expression of PAX7 among the CD49f+ spermatogonia, and PAX7 can maintain the self-renewal of CD49f-positive SSCs.

Hsa-miR-1908-3p Mediates the Self-Renewal and Apoptosis of Human Spermatogonial Stem Cells via Targeting KLF2. MOLECULAR THERAPY. NUCLEIC ACIDS 2020; 20:788-800. [PMID: 32438314 PMCID: PMC7240205 DOI: 10.1016/j.omtn.2020.04.016] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/07/2020] [Revised: 04/15/2020] [Accepted: 04/28/2020] [Indexed: 12/19/2022]
Abstract
Spermatogenesis depends on precise epigenetic and genetic regulation of spermatogonial stem cells (SSCs). However, it remains largely unknown about the roles and mechanisms of small noncoding RNA in regulating the self-renewal and apoptosis of human SSCs. Notably, we have found that Homo sapiens-microRNA (hsa-miR)-1908-3p is expressed at a higher level in human spermatogonia than pachytene spermatocytes. MiR-1908-3p stimulated cell proliferation and DNA synthesis of the human SSC line. Allophycocyanin (APC) Annexin V and propidium iodide staining, determined by flow cytometric analysis and TUNEL assays, showed that miR-1908-3p inhibited early and late apoptosis of the human SSC line. Furthermore, Kruppel-like factor 2 (KLF2) was predicted and verified as the target of miR-1908-3p, and, significantly, KLF2 silencing resulted in the increase of proliferation and DNA synthesis, as well as reduction of apoptosis of the human SSC line. Moreover, KLF2 silencing ameliorated the decrease in the proliferation and DNA synthesis and the enhancement in the apoptosis of the human SSC line caused by miR-1908-3p inhibition. Collectively, these results implicate that miR-1908-3p stimulates the self-renewal and suppresses the apoptosis of human SSCs by targeting KLF2. This study thus provides a novel epigenetic regulatory mechanism underlying the fate determinations of human SSCs, and it offers new endogenous targets for treating male infertility.

Paternal high-fat diet and exercise regulate sperm miRNA and histone methylation to modify placental inflammation, nutrient transporter mRNA expression and fetal weight in a sex-dependent manner. J Nutr Biochem 2020; 81:108373.

Abstract
We previously have shown that male offspring (F1) of fathers (F0) fed a high-fat (HF) diet and that exercised had greater skeletal muscle insulin signaling and reduced type 2 diabetes mellitus (T2DM) risk compared to fathers fed HF diet and that remained sedentary. The current study extends this work by hypothesizing that F0 HF diet and exercise regulate F1 T2DM risk by alterations in placental tissue growth via changes in sperm miRNA expression. To test these hypotheses, 3-week-old male C57BL/6 mice were fed a normal-fat diet (16% fat) or an HF diet (45% fat) and assigned to either voluntary wheel running exercise or cage activity for 3 months. Results showed that F0 sperm miRNA 193b expression was decreased while miRNA 204 was increased by paternal exercise. Protein expression of dimethylated histone 3 lysine 9 was decreased with F0 HF diet. Placental and fetal tissue weights were decreased by F0 HF diet in F1 males. Placental interleukin-1β and tumor necrosis factor (TNF)-α mRNA expression was reduced by paternal exercise, while nutrient transporter mRNA expression was decreased by paternal HF diet only in the placentae of F1 females. Treatment of primary placental cell with miRNA 193b inhibited TNF-α mRNA expression, and treatment of TNF-α decreased SLC38a2 mRNA expression. Moreover, paternal exercise increased body weight at weaning in a female offspring. These results demonstrate that placental tissue weight, placental nutrient transporter gene expression and fetal weights are altered by paternal exercise, while placental inflammatory gene expression is influenced by paternal exercise in offspring in a sex-specific manner.

Abstract
The miRNA gene in DNA is first transcribed to Pri-miRNA, and then processed to Pre-miRNA, a stem-loop RNA segment (precursor) and further to miRNA which binds to mRNA by Dicer protein complex. It was confirmed that goat miR-204 could regulate the expressions of Sirt1 and the SSCs' (Spermatogonial Stem Cells) important genes Oct4 and Plzf, and inhibit the proliferation of dairy goat SSCs in vitro in our previous work. So, the research in vivo was needed next. In this study, the recombinant lentivirus vector pCDH-CMV-mir204-EF1-GreenPuro containing a goat chi-pri-mir-204 gene DNA segment was structured, and transfected into 293 T cells for packaged lentivirus, which then were injected into mouse seminiferous tubules. After 7 days, the goat miR-204 and the related genes such as Sirt1 and Plzf were detected in the mouse testis. This work laid a good foundation for further study of miR-204 biological function in vivo.

Abstract
Myotubularin related protein 7 (MTMR7), a key member of the MTMR family, depicts phosphatase activity and is involved in myogenesis and tumor growth. We have previously identified MTMR7 in the proteomic profile of mouse spermatogonial stem cell (SSC) maturation and differentiation, implying that MTMR7 is associated with neonatal testicular development. In this study, to further explore the distribution and function of MTMR7 in mouse testis, we studied the effect of Mtmr7 knockdown on neonatal testicular development by testicular and SSC culture methods. Our results revealed that MTMR7 is exclusively located in early germ cells. Deficiency of MTMR7 by morpholino in neonatal testis caused excessive SSC proliferation, which was attributable to the aberrant PI3K/AKT signaling activation. Altogether, our study demonstrates that MTMR7 maintains SSC homeostasis by inhibiting PI3K/AKT signaling activation.

Abstract
Spermatogenesis is a complicated process including spermatogonial stem cells self-renewal and differentiates into mature spermatozoa. MicroRNAs (miRNAs) as a class of small non-coding RNAs play a crucial role during the process of spermatogenesis. However, the function of a plenty of miRNAs on spermatogenesis and the potential mechanisms remain largely unknown. Here, we show that genetically conditional overexpressed miR-10a in germ cells caused complete male sterility, characterized by meiotic arrested in germ cells. Analysis of miR-10a overexpression mouse testes reveals that failure of double strand break (DSB) repairs and aberrant spermatogonial differentiation. Furthermore, we identified Rad51 as a key target of miR-10a in germ cell by bioinformatics prediction and luciferase assay, which may be responsible for the infertility of the miR-10a overexpressed mice and germ cell arrested patients. Our data show that miR-10a dependent genetic regulation of meiotic process is crucial for male germ cell development and spermatogenesis in both mouse and human. These findings facilitate our understanding of the roles of miRNA-10a in spermatogenesis and male fertility.

Abstract
Several lines of evidence highlight the important application of human spermatogonial stem cells (SSCs) in translational medicine. The fate decisions of SSCs are mainly mediated by genetic and epigenetic factors. We have recently demonstrated that PAK1 regulates the proliferation, DNA synthesis, and early apoptosis of human SSCs through the PDK1/KDR/ZNF367 and ERK1/2 and AKT pathway. However, the underlying epigenetic mechanism of PAK1 in human SSCs remains unknown. In this study, we found that the level of miRNA-31-5p was elevated by PAK1 knockdown. CCK-8, PCNA, and 5-ethynyl-2′-deoxyuridine (EDU) assays revealed that miRNA-31-5p mimics inhibited cell proliferation and DNA synthesis of human SSCs. Annexin V/propidium iodide (PI) staining and flow cytometry showed that miRNA-31-5p increased the early and late apoptosis of human SSCs. Furthermore, JAZF1 was predicted and verified as a target of miRNA-31-5p, and the three-dimensional (3D) structure model of JAZF1 protein was illustrated. JAZF1 silencing led to a reduction of cell proliferation and DNA synthesis as well as an enhancement of the early and late apoptosis of human SSCs. Finally, miRNA-31-5p mimics decreased the level of cyclin A2 rather than cyclin D1 or cyclin E1, and JAZF1 knockdown led to the reduction of cyclin A2 in human SSCs. Collectively, miRNA-31-5p regulates the proliferation, DNA synthesis, and apoptosis of human SSCs by the PAK1-JAZF1-cyclin A2 pathway. This study thus offers a novel insight into the molecular mechanisms underlying the fate determinations of human SSCs and might provide novel targets for molecular therapy of male infertility.

Abstract
Spermatogonial stem cells (SSCs), a unique population of male germ cells with self-renewal ability, are the foundation for maintenance of spermatogenesis throughout the life of the male. Although many regulatory molecules essential for SSC self-renewal have been identified, the fundamental mechanism underlying how SSCs acquire and maintain their self-renewal activity remains largely to be elucidated. In recent years, many types of noncoding RNAs (ncRNAs) have been suggested to regulate the SSC self-renewal through multiple ways, indicating ncRNAs play crucial roles in SSC self-renewal. In this paper, we mainly focus on four types of ncRNAs including microRNA, long ncRNA, piwi-interacting RNA, as well as circular RNAs, and reviewed their potential roles in SSC self-renewal that discovered recently to help us gain a better understanding of molecular mechanisms by which ncRNAs perform their function in regulating SSC self-renewal.

Abstract
MicroRNAs (miRNAs) are a novel class of small noncoding RNAs (ncRNAs) that play critical roles in regulation of gene expression, especially at posttranscriptional level. Over the past decade, the degree to which miRNAs are involved in male infertility has become clear. They are expressed in a cell- or phase-specific manner during spermatogenesis and play crucial role in male reproductive health. Therefore, dysregulation of miRNAs in testicular cells can be considered as a molecular basis for reproductive failure and male infertility. The abnormal expression pattern of miRNAs can be transmitted to the offspring via assisted reproductive techniques (ART) and results in the birth of children with a higher risk of infertility, congenital abnormalities, and morbidity. This review expounds on the miRNAs reported to play essential roles in somatic cells development, germ cells differentiation, steroidogenesis, normal spermatogenesis, sperm maturation, and male infertility, as well as emphasizes their importance as minimally invasive biomarkers of male infertility.

Abstract
Mature differentiated macrophages can self-maintain by local proliferation in tissues and can be extensively expanded in culture under specific conditions, but the mechanisms of this phenomenon remain only partially defined. Here, we show that SIRT1, an evolutionary conserved regulator of life span, positively affects macrophage self-renewal ability in vitro and in vivo Overexpression of SIRT1 during bone marrow-derived macrophage differentiation increased their proliferative capacity. Conversely, decrease of SIRT1 expression by shRNA inactivation, CRISPR/Cas9 mediated deletion and pharmacological inhibition restricted macrophage self-renewal in culture. Furthermore, pharmacological SIRT1 inhibition in vivo reduced steady state and cytokine-induced proliferation of alveolar and peritoneal macrophages. Mechanistically, SIRT1 inhibition negatively regulated G1/S transition, cell cycle progression and a network of self-renewal genes. This included inhibition of E2F1 and Myc and concomitant activation of FoxO1, SIRT1 targets mediating cell cycle progression and stress response, respectively. Our findings indicate that SIRT1 is a key regulator of macrophage self-renewal that integrates cell cycle and longevity pathways. This suggests that macrophage self-renewal might be a relevant parameter of ageing.

Abstract
Mammalian spermatogenesis contains three continuous and organized processes, by which spermatogonia undergo mitosis and differentiate to spermatocytes, follow on meiosis to form haploid spermatids and ultimately transform into spermatozoa. These processes require an accurately, spatially and temporally regulated gene expression patterns. The microRNAs are a novel class of post-transcriptional regulators. Cumulating evidences have demonstrated that microRNAs are expressed in a cell-specific or stage-specific manner during spermatogenesis. In this review, we focus on the roles of microRNAs in spermatogenesis. We highlight that N6-methyladenosine (m6A) is involved in the biogenesis of microRNAs and miRNA regulates the m6A modification on mRNA, and that specific miRNAs have been exploited as potential biomarkers for the male factor infertility, which will provide insightful understanding of microRNA roles in spermatogenesis.

Abstract
Exosomes and microvesicles (i.e., extracellular vesicles: EVs) have been identified within ovarian follicular fluid and recent evidence suggests that EVs are able to elicit profound effects on ovarian cell function. While existence of miRNA within EVs has been reported, whether EV size and concentration as well as their cargos (i.e., proteins and RNA) change during antral follicle growth remains unknown. Extracellular vesicles isolated from follicular fluid of small, medium and large bovine follicles were similar in size, while concentration of EVs decreased progressively as follicle size increased. Electron microscopy indicated a highly purified population of the lipid bilayer enclosed vesicles that were enriched in exosome biomarkers including CD81 and Alix. Small RNA sequencing identified a large number of known and novel miRNAs that changed in the EVs of different size follicles. Ingenuity Pathway Analysis (IPA) indicated that miRNA abundant in small follicle EV preparations were associated with cell proliferation pathways, while those miRNA abundant in large follicle preparations were related to inflammatory response pathways. These studies are the first to demonstrate that EVs change in their levels and makeup during antral follicle development and point to the potential for a unique vesicle-mediated cell-to-cell communication network within the ovarian follicle.

Abstract
Throughout the globe, diabetes mellitus (DM) is increasing in incidence with limited therapies presently available to prevent or resolve the significant complications of this disorder. DM impacts multiple organs and affects all components of the central and peripheral nervous systems that can range from dementia to diabetic neuropathy. The mechanistic target of rapamycin (mTOR) is a promising agent for the development of novel regenerative strategies for the treatment of DM. mTOR and its related signaling pathways impact multiple metabolic parameters that include cellular metabolic homeostasis, insulin resistance, insulin secretion, stem cell proliferation and differentiation, pancreatic β-cell function, and programmed cell death with apoptosis and autophagy. mTOR is central element for the protein complexes mTOR Complex 1 (mTORC1) and mTOR Complex 2 (mTORC2) and is a critical component for a number of signaling pathways that involve phosphoinositide 3-kinase (PI 3-K), protein kinase B (Akt), AMP activated protein kinase (AMPK), silent mating type information regulation 2 homolog 1 (Saccharomyces cerevisiae) (SIRT1), Wnt1 inducible signaling pathway protein 1 (WISP1), and growth factors. As a result, mTOR represents an exciting target to offer new clinical avenues for the treatment of DM and the complications of this disease. Future studies directed to elucidate the delicate balance mTOR holds over cellular metabolism and the impact of its broad signaling pathways should foster the translation of these targets into effective clinical regimens for DM.

Abstract
Male germline stem cells (mGSCs) presented in male testis are responsible for spermatogenesis during their whole life. However, little information can be found on the culture of bovine mGSCs, and the current culture system needs to be improved. In this study, we compared the effects of several commercial serum-free media and different extra-cellular matrix on the enrichment and cultivation of mGSCs. To find out the best culture condition, the biological characteristics of the cultured cells were evaluated by morphological observation, RT-PCR and immunofluorescent staining. According to the cells' condition in different experiment groups, we found out an efficient cultivation system for bovine mGSCs derived from neonate testis. In this serum- and feeder-free medium, the cultured cells maintained the typical morphology, and expressed specific surface markers of both pluripotent ES cells and mGSCs, including SSEA-1, CD49f, C-MYC, PLZF, GFRα1, LIN28, NANOG, Oct4 and SOX2 in commercial human ESCs medium PeproGrow-hESC + BIO (6-bromoindirubin-3'-oxime). Embryoid bodies, derived from the bovine mGSCs, and were formed by ganging drop culture. The retinoic acid induced bovine mGSCs were positive for Stra8, SCP3, DZAL, EMA1 and VASA, and resembled spermatid cells morphologically. Thus, we found an efficient bovine mGSCs-cultivation system, which is lack in serum and feeder.
