Abstract
Ras p21 protein activator 1 (RASA1) is a regulator of Ras GDP and GTP and is involved in numerous physiological processes such as angiogenesis, cell proliferation, and apoptosis. As a result, RASA1 also contributes to pathological processes in vascular diseases and tumour formation. This review focuses on the role of RASA1 in multiple tumours types in the lung, intestines, liver, and breast. Furthermore, we discuss the potential mechanisms of RASA1 and its downstream effects through Ras/RAF/MEK/ERK or Ras/PI3K/AKT signalling. Moreover, miRNAs are capable of regulating RASA1 and could be a novel targeted treatment strategy for tumours.

[PMID: 31044548 DOI: 10.1111/andr.12639] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2018] [Revised: 03/01/2019] [Accepted: 03/30/2019] [Indexed: 12/15/2022]
Abstract
BACKGROUND Small non-coding RNAs (sncRNAs) accomplish a huge variety of biological functions. Over the past decade, we have witnessed the substantial progress in the epididymal sncRNA studies. In the Epididymis 7, we had the true privilege of having a whole session to share our findings and exchange ideas on the epididymal sncRNA studies. OBJECTIVES This mini-review attempts to provide an overview of what is known about the sncRNAs in the mammalian epididymis and discuss the future directions in this field. METHODS We surveyed literature regarding the sncRNA studies in the mammalian epididymis, and integrated some of our unpublished findings as well. We focus on the progress in methodology and the advances in our understanding of the expression and functions of epididymal sncRNAs. RESULTS AND DISCUSSION The applications of high-throughput approaches have made great contributions in the discovery of new sncRNA species and profiling their dynamics in the epithelial cells, the passing spermatozoa, and the luminal environment. The diverse classes of epididymal sncRNAs exert important biological functions from the in situ regulation of epididymal gene expression to the epigenetic inheritance in the offspring. CONCLUSION Although still in its infancy, we believe that the research on epididymal sncRNAs will not only lead to a better understanding of their physiological and pathological functions, but also contribute to the whole landscape of the RNA field.

Abstract
BACKGROUND Puberty is the period during a female mammal's life when it enters estrus and ovulates for the first time; this indicates that a mammal is capable of reproduction. The onset of puberty is a complex and tightly coordinated biological event; it has been reported that microRNAs (miRNAs) are involved in regulating the initiation of puberty. METHODS We performed miRNA sequencing on pituitary tissue from prepubescent and pubescent goats to investigate differences in miRNA expression during the onset of puberty in female goats. The target genes of these miRNAs were evaluated by GO enrichment and KEGG pathway analysis to identify critical pathways regulated by these miRNAs during puberty in goats. Finally, we selected four known miRNA and one novel miRNAs to evaluate expression patterns in two samples via qRT-PCR to validate the RNA-seq data. RESULTS In this study, 476 miRNAs were detected in goat pituitary tissue; 13 of these were specifically expressed in the pituitary of prepubescent goats, and 17 were unique to the pituitary of pubescent goats. Additionally, 73 novel miRNAs were predicted in these two libraries. 20 differentially expressed miRNAs were identified in this study. KEGG pathway enrichment analysis revealed that the differentially expressed miRNA target genes were enriched in pathways related to ovary development during puberty, including the GABAergic synapse, oxytocin signaling pathway, the cAMP signaling pathway, progesterone-mediated oocyte maturation. In this study, differential miRNA expression in the pituitary tissue of prepubescent and pubescent goats were identified and characterized. CONCLUSION These results provide important information regarding the potential regulation of the onset of goat puberty by miRNAs, and contribute to the elucidation of miRNA regulated processes during maturation and reproduction.

Abstract
The epididymis is necessary for post-testicular sperm maturation. During their epididymal transit, spermatozoa gain ability for progressive movement and fertilization. The epididymis is composed of several segments that have distinct gene expression profiles that enable the establishment of the changing luminal environment required for sperm maturation. The epididymal gene expression is regulated by endocrine, lumicrine, and paracrine factors in a segment-specific manner. Thus, in addition to its importance for male fertility, the epididymis is a valuable model tissue for studying the regulation of gene expression. This review concentrates on recent advances in understanding the androgen, small RNA, and epigenetically mediated regulation of segment-specific gene expression in the epididymis.

Abstract
MicroRNA miR-335 has been reported to have both tumor suppressor and oncogenic activities. In order to determine possible tissue and cell type differences in response to miR-335, we examined the effect of miR-335 on cell expression of MT1-MMP, a proteinase commonly expressed in tumors and associated with cell proliferation and migration. miR-335 increased cell surface expression of MT1-MMP in fibrosarcoma HT-1080 and benign prostate BPH-1 cells, but not in prostate LNCaP or breast MCF-7 tumor cells. miR-335 stimulated proliferation and cell migration in a wound healing in vitro assay in HT-1080, BPH-1, and U87 glioblastoma cells, cells which demonstrated significant cell surface expression of MT1-MMP. In contrast, miR-335 did not affect proliferation or migration in cells without a prominent plasma membrane associated MT1-MMP activity. Our data suggest that differences in response to miR-335 by tumor cells may lie in part in the mechanism of regulation of MT1-MMP production.

Epididymal Region-Specific miRNA Expression and DNA Methylation and Their Roles in Controlling Gene Expression in Rats. PLoS One 2015; 10:e0124450.

Abstract
Region-specific gene expression is an intriguing feature of the mammalian epididymis. This unique property is essential for sperm maturation and storage, and it also implicates stringent and multi-level regulations of gene expression. Over the past decade, the androgen-driven activation of epididymal gene transcription has been extensively studied. However, it still remains largely unexplored whether and how other regulatory mechanisms, such as miRNAs and DNA methylation, are involved in controlling regional gene expression in the epididymis. Using microarray-based approaches, we studied the regional miRNA expression and DNA methylation profiles in 4 distinct epididymal regions (initial segment, caput, corpus and cauda) of rats. We found that the miR-200 family members were more expressed in caput, compared with cauda. By GSEA analysis, the differential expression of miR-200 family between caput and cauda was shown to be negatively correlated with their predicted target genes, among which 4 bona fide targets were verified by luciferase reporter assay. Predicted target genes of miR-200 family have enriched functions in anti-apoptosis, cell transportation and development, implying the regional diversity in epididymal functions. On the other hand, we revealed epididymal DNA methylation of 2002 CpG islands and 2771 gene promoters (-3.88-0.97 kb), among which 1350 (67.43%) CpG islands and 2095 (75.60%) promoters contained region-specific DNA methylation. We observed significant and distinct functional enrichment in genes with specifically methylated promoters in each epididymal regions, but these DNA methylations did not show significant correlation with repressed gene transcription in the mature epididymis. Conclusively, we investigated the regional miRNA expression and DNA methylation in the rat epididymis and revealed a potential role of miR-200 family in gene expression regulation between caput and cauda. This may contribute to the distinct physiological function in sperm maturation / storage of caput / cauda epididymis.

Abstract
MicroRNA is a short RNA molecule expressed in eukaryotic cells that is involved in multiple processes, including translational repression, target degradation and gene silencing. However, its specific role(s) in these processes remains largely unknown, especially in terms of germ cell development. The present study identified a microRNA, namely miR-335-5p, that is involved in mouse oocyte meiosis. MiR-335-5p was highly expressed in oocytes, but levels decreased markedly shortly after fertilisation. Microinjection of miR-335-5p or its inhibitor into oocytes resulted in a higher proportion of 2-cell-like MII oocytes and oocytes at the germinal vesicle breakdown and/or MI stage, indicating failure of asymmetric oocyte division. This may be due to regulation of actin because perturbation of miR-335-5p resulted in reduced expression of actin nucleator Daam1, a member of the Formin family. Moreover, injection of miR-335-5p or its inhibitor resulted in aberrant spindle morphology, namely an elongated spindle and multiple poles spindle. After injection of oocytes, levels of phosphorylated extracellular signal-regulated kinase 1/2 (ERK1/2) decreased, suggesting that miR-335-5p may regulate spindle formation via the mitogen-activated protein kinase pathway. Overexpression and inhibition of miR-335-5p had no effect on embryo development. Together, the results of the present study indicate that miR-335-5p is a novel regulator expressed in oocytes that is involved in cytoskeleton dynamics.

Abstract
MicroRNA-335 (miR-335) acts as a tumor suppressor or a tumor promoter in different human malignancies. However, the involvement of miR-335 in prostate cancer (PCa) is still unclear. The purpose of this study was to investigate the functional and clinical significance of miR-335 in PCa. miR-335 expression in 3 PCa cell lines (LNCaP/DU145/PC3) and in 20 clinical PCa tissues were detected by real-time quantitative reverse transcriptase-PCR compared with corresponding controls. The function of miR-335 was investigated for cell proliferation, invasion and migration in PCa cells transfected with agents containing EGFP-miR-335 expression vector. Additionally, miR-335 expression in 104 clinical PCa tissues was detected by in situ hybridization. Its assocaitions with clinicopathological features and prognosis in patients with PCa were also determined. miR-335 was significantly down-regulated in PCa cell lines than in the normal prostate cell line (P < 0.01). With the similar results in vitro, the reduced expression of miR-335 was also found in human PCa tissues comparing with paired adjacent benign prostate tissues (P < 0.05). Moreover, the increased expression of miR-335 suppressed cell proliferation, invasion and migration of PCa cell lines in vitro. Turning to its clinical significance, the low expression of miR-335 was significantly associated with high Gleason Score (P = 0.04), advanced clinical stage (P = 0.04), and positive metastasis (P = 0.02), but not with prognosis in PCa patients. Our data demonstrated for the first time the inhibitory effect of miR-335 on cell proliferation and invasion for PCa cells. The loss of this microRNA might be associated with clinical progression of PCa patients.

Abstract
Background The postnatal development of the epididymis is a complex process that results in a highly differentiated epithelium, divided into several segments. Recent studies indicate a role for RNA interference (RNAi) in the development of the epididymis, however, the actual requirement for RNAi has remained elusive. Here, we present the first evidence of a direct need for RNAi in the differentiation of the epididymal epithelium. Methodology/Principal Findings By utilizing the Cre-LoxP system we have generated a conditional knock-out of Dicer1 in the two most proximal segments of the mouse epididymis. Recombination of Dicer1, catalyzed by Defb41iCre/wt, took place before puberty, starting from 12 days postpartum. Shortly thereafter, downregulation of the expression of two genes specific for the most proximal epididymis (lipocalin 8 and cystatin 8) was observed. Following this, segment development continued until week 5 at which age the epithelium started to regress back to an undifferentiated state. The dedifferentiated epithelium also showed an increase in estrogen receptor 1 expression while the expression of androgen receptor and its target genes; glutathione peroxidase 5, lipocalin 5 and cysteine-rich secretory protein 1 was downregulated, indicating imbalanced sex steroid signaling. Conclusions/Significance At the time of the final epididymal development, Dicer1 acts as a regulator of signaling pathways essential for maintaining epithelial cell differentiation.

Abstract
Cell proliferation often decreases gradually during postnatal development of some organs. However, the underlying molecular mechanisms remain unclear. Epididymis, playing important roles in sperm maturation, is a typical organ of this type, which displays a decreased proliferation during postnatal development and even ceased at the adult stage. Here, epididymis was employed as a model to explore the underlying mechanisms. We profiled the microRNA and mRNA expression of newborn (1 day) and adult (90 day) rat epididymis by microarray analysis, and found that the level of miR-29a was dramatically up-regulated during postnatal development of rat epididymis. Subsequent investigations demonstrated that overexpression of miR-29a inhibited the proliferation of epididymal epithelial cells in vitro. The nuclear autoantigenic sperm protein (NASP), a novel target of miR-29a, was significantly down-regulated during postnatal development of rat epididymis. Further analysis showed that silence of NASP mimicked the anti-proliferation effect of miR-29a, whereas overexpression of this protein attenuated the effect of miR-29a. As in rat epididymis, miR-29a was up-regulated and Nasp was down-regulated during postnatal development of mouse epididymis, heart, liver, and lung. Moreover, miR-29a can also inhibit the proliferation of cancer cells by targeting Nasp. Thus, an increase of miR-29a, and hence decrease of Nasp, may contribute to inhibit cell proliferation during postnatal organ development.

Abstract
A long and ever-expanding roster of small (∼20–30 nucleotides) RNAs has emerged during the last decade, and most can be subsumed under the three main headings of microRNAs(miRNAs), Piwi-interacting RNAs(piRNAs), and short interferingRNAs(siRNAs). Among the three categories, miRNAs is the most quickly expanded group. The most recent number of identified miRNAs is 16,772 (Sanger miRbase, April 2011). However, there are insufficient publications on their primary forms, and no tissue-specific small RNAs precursors have been reported in the epididymis. Here, we report the identification in rats of an epididymis-specific, chimeric, noncoding RNA that is spliced from two different chromosomes (chromosomes 5 and 19), which we named HongrES2. HongrES2 is a 1.6 kb mRNA-like precursor that gives rise to a new microRNA-like small RNA (mil-HongrES2) in rat epididymis. The generation of mil-HongrES2 is stimulated during epididymitis. An epididymis-specific carboxylesterase named CES7 had 100% cDNA sequence homology at the 3′end with HongrES2 and its protein product could be downregulated by HongrES2 via mil-HongrES2. This was confirmed in vivo by initiating mil-HongrES2 over-expression in rats and observing an effect on sperm capacitation.
