“…Furthermore, it was indicated that hsa-miR-4508 was a significant highly expressed miRNA in exosomes. It has been reported that circulating hsa-miR-4508 was significantly upregulated in acute myocardial infarction [ 37 ] and patients receiving dexmedetomidine [ 38 ]. However, its functions remain elusive.…”

The present study is aimed at profiling circulating exosome-derived microRNAs (miRNAs/miRs) from patients with dermatomyositis (DM), in particular those complicated with interstitial lung disease (ILD) with anti-melanoma differentiation-associated protein 5 (MDA5) antibody-positive. Fifteen participants were enrolled, including five patients with DM complicated with ILDs prior to treatment with circulating anti-MDA5 antibody-positive status [DM-ILD-MDA5 Ab(+)], five DM patients without ILDs who were negative for 16 detectable myositis-specific antibodies [DM-nonILD-MSA16(-)], and five age- and gender-matched healthy donor controls (HCs). The characteristics of the exosomes extracted by Ribo™ Exosome Isolation Reagent were identified using transmission electron microscopy (TEM), nanoparticle tracking analysis (NTA), and flow cytometry. Differentially expressed miRNAs, determined by next-generation deep sequencing, were identified through the criteria of ∣ log 2 fold change ∣ ≥ 1 and P < 0.01 . A total of 38 miRNAs were significantly upregulated in exosomes from patients with DM-ILD-MDA5 Ab(+) compared to those from HC, while 21 miRNAs were significantly downregulated. Compared to exosomes derived from patients with DM-nonILD-MSA16(-), 51 miRNAs were significantly upregulated and 33 miRNAs were significantly downregulated from patients with DM-ILD-MDA5 Ab(+). A total of 73 exosomal miRNAs were significantly differentially expressed between DM-nonILD-MSA16(-) and HC. In particular, two miRNAs, Homo sapiens- (hsa-) miR-4488 and hsa-miR-1228-5p, were common differentially expressed miRNAs among three comparisons. GO and KEGG analyses suggested that several pathways may contribute the pathogenesis of DM-ILD-MDA5 Ab(+) and DM-nonILD-MSA16(-), while PPI network analysis of hsa-miR-4488 and hsa-miR-1228-5p indicated that their predicted target genes, DExD-box helicase 39B and MDM2, may be involved in the mechanisms of DM-ILD-MDA5 Ab(+).

“…MicroRNAs (miRNAs) are one family of small non‐coding RNAs that regulate gene expression post‐transcriptionally, generally by binding to specific motifs in the 3’‑untranslated regions (3’UTRs) of target genes Bartel, (2009). MicroRNAs coordinate diverse biological events, including differentiation, apoptosis, proliferation, reproduction, stress response, metabolism, immune response and stem cell maintenance (Beitzinger et al., 2007; Gangaraju & Lin, 2009; Huang et al., 2011; Zhang et al., 2013; Junhua et al., 2017; Yang, Chen, et al., 2018). MicroRNAs have been shown to play an important role in the acquisition and maintenance of male fertility.…”

The epididymis is the site of post‐testicular sperm maturation, which constitutes the acquisition of sperm motility and the ability to recognize and fertilize oocytes. The role of miRNA in male reproductive system, including the control of different steps leading to proper fertilization such as gametogenesis, sperm maturation and maintenance of male fertility where the deletion of Dicer in mouse germ cells led to infertility, has been demonstrated. The identification of miRNA expression in a region‐specific manner will therefore provide valuable insight into the functional differences between the regions of the epididymis. In this study, we employed RNA‐seq technology to explore the expression pattern of miRNAs and establish some miRNAs of significant interest with regard to epididymal sperm maturation in the CY epididymis. We identified a total of 431 DE known miRNAs; 119, 185 and 127 DE miRNAs were detected for caput versus corpus, corpus versus cauda and caput versus cauda region pairs, respectively. Our results demonstrate region‐specific miRNA expression in the CY epididymis. The GO and KEGG enrichment for the predicted target genes indicated the functional values of miRNAs. Furthermore, we observed that the expression of miR‐200a was downregulated in the caput, compared with cauda. Since the family of miR‐200 has previously been suggested to contribute to the distinct physiological function of sperm maturation in epididymis of adult rat, we speculate that the downregulation of miR‐200a in CY caput epididymis may play an important role of sperm maturation in the epididymis of CY. Therefore, our findings may not only increase our understanding of the molecular mechanisms regulated by the miRNA functions in region‐specific miRNA expression in the CY epididymis, it could provide a valuable information to understand the mechanism of male infertility of CY.

“…Recently, microRNAs (miRNAs) have been revealed to play vital roles in modulating pain transmission in animal experiments and clinical studies (Dai et al., 2019). For instance, hsa‐miR‐101‐3p has been identified as one of the seven miRNAs that were reduced after delivery of Dex to the subjects (Yang et al., 2018). The neuroprotective role of miR‐101 has been underscored in Alzheimer's disease (Vilardo, Barbato, Ciotti, Cogoni, & Ruberti, 2010).…”

New Findings What is the central question of this study?Dexmedetomidine has a capacity for sedation, anti‐anxiety and analgesia with minimal suppression of respiratory function; what is its role in neuropathic pain and what is the involvement of miRNAs? What is the main finding and its importance?Dexmedetomidine attenuates inflammation and apoptosis and the stimulation of TLR4–NF‐κB signalling in rat spinal cord via miR‐101 overexpression and E2F2 downregulation. Abstract The significant analgesic effect of dexmedetomidine (Dex) has been underscored in neuropathic pain (NPP), but the underlying mechanism remains unclear. This study explored the functional effect of Dex on microRNA (miR)‐101‐regulated E2 promoter binding factor 2 (E2F2) with the engagement of Toll‐like receptor 4 (TLR4)–nuclear factor‐κB (NF‐κB) signalling. Chronic constriction injury (CCI) was performed to generate an NPP rat model. The expression of miR‐101, E2F2 and TLR4–NF‐κB signalling‐relevant proteins was assessed by RT–quantitative PCR, immunoblotting and immunohistochemistry. Inflammatory factors were detected by enzyme‐linked immunosorbent assay. The results showed that Dex increased mechanical withdrawal threshold and thermal latency to withdraw. The expression of interleukin (IL)‐6, IL‐8 and tumour necrosis factor‐α was increased in CCI rats, but these trends were reversed by Dex. In addition, Dex repressed caspase‐9 expression and apoptotic cell numbers in spinal cord tissues in CCI rats. Moreover, the expression of E2F2 was significantly increased, while miR‐101 was diminished in CCI rats, which was reversed by Dex. Furthermore, miR‐101 inhibitor, E2F2 restoration or administration of a TLR4‐specific agonist weakened the effect of Dex. Together, these results suggest that Dex has the capacity to ameliorate NPP by regulating the miR‐101–E2F2–TLR4–NF‐κB axis in rats subjected to CCI.
