MicroRNAs (miRNAs) are small noncoding RNAs that regulate protein translation by binding to complementary target mRNAs. We previously identified two mature members of the miR-142 family, miR-142-5p and miR-142-3p, as inflammation-related miRNAs with potential roles in wound healing. Here, we demonstrated that these two miRNAs are prominently expressed in wound-infiltrated neutrophils and macrophages and play central roles in wound healing. We generated miR-142(-/-) mice using the exchangeable gene-trap method and showed that healing of Staphylococcus aureus-infected skin wounds was significantly delayed in miR-142(-/-) mice compared with that in wild-type mice...

Over the last decade, microRNA-142 (miR-142) is emerging as a major regulator of cell fate decision in the hematopoietic system. However, miR-142 is expressed in many other tissues and recent evidence suggest that it may play a more pleiotropic role during embryonic development. In addition, miR-142 has been shown to play important functions in disease. miR-142 displays a functional role in cancer, virus infection, inflammation and immune tolerance. Both a guide strand (miR-142-3p) and passenger strand (miR-142-5p) are generated from the miR-142 hairpin...

Small non-coding RNAs (sncRNA; <200 nt) regulate various cellular processes and modify gene expression. Under nutritional, biological or physiochemical stress some mature sncRNAs (e.g. tRNAs) are cleaved into halves (30-50 nt) and smaller fragments (18-22 nt); the significance and functional role of these tRNA fragments is unknown, but their existence has been linked to carcinogenesis. We used small RNA sequencing to determine the expression of sncRNAs. Subsequently the findings were validated for miR-122-5p, miR-142-3p and 5'tRNA4-Val-AAC using qPCR...

BACKGROUND: Recent studies have shown that alterations in the function of dendritic cells (DCs) are involved in the pathogenesis of systemic lupus erythematosus (SLE). However, the mechanism of the alteration remains unclear. METHODS: We cultured monocyte-derived DCs (moDCs) in vitro and examined the cytokines and chemokines in the supernatants of moDCs in negative controls (NC) and SLE patients in active phase. We then profiled microRNAs (miRNAs) of LPS-stimulated moDCs in SLE patients and used real-time PCR to verify the differentially expressed miRNAs...

Cutaneous squamous cell carcinoma (cSCC) is the most common type of non-melanoma skin cancer that can metastasize. The major etiological factor associated with cSCC is Ultraviolet radiation (UVR) with a limited understanding of its molecular mechanism. It was hypothesized that there is a direct effect of UVR on modulation of microRNAs (miRNAs), a novel class of short noncoding RNAs which affects translation and stability of mRNAs. To test the hypothesis, the dorsal skin of the SKH1 mice (6-7 week old) was exposed to acute and chronic doses of UVR...

Macrophages are innate immune cells that are important contributors to age-related functional impairment of the immune system. During the cell aging process, microRNAs are differentially expressed and participate in the regulation of aging-related immune responses. However, the role of aging-associated changes in miRNA expression in macrophages remains unclear. Here, we found that miR-142-3p expression is downregulated 50% in peritoneal macrophages from aged mice compared with young mice and is not upregulated by cell treatment with lipopolysaccharide (LPS), CpG, or polyinosinic-polycytidylic acid...

AIM: Micro ribonucleic acids (miRNAs) play an important pathological role in endometriosis. Leuprolide acetate, an analog of gonadotropin-releasing hormone, is widely used to treat endometriosis; however, the molecular mechanisms involved in endometriotic tissue regression remain unclear. We performed miRNA expression profiling of clinical ovarian endometrioma to obtain insight into the effects of leuprolide acetate treatment. METHODS: We obtained clinical samples from nine normal eutopic endometrium, eight ovarian endometriotic, and 12 leuprolide acetate-treated endometriotic tissues...

BACKGROUND: Tuberous sclerosis (TSC) is a monogenic disease resulting from defects of the TSC1 or TSC2 genes, which encode the proteins forming hamartin-tuberin tumor suppressor complex, the mammalian target of rapamycin complex (mTOR). The mTOR pathway is constitutively activated in response to tuberin or hamartin defects. The mTOR pathway is also regulated by a multitude of epigenetic mechanisms, one of which is regulation by microRNA (miRNA) inhibition. This leads us to hypothesize that organ-level abnormalities of miRNA expression patterns are widespread in TSC...

Plasma microRNAs (miRNAs) have been proposed as potential biomarkers in Alzheimer's disease (AD). Here, we explored their use as early sensors of the preclinical phase of the disease, when brain pathology is being developed and no cognitive loss is detected. For this purpose, we analyzed a set of ten mature plasma miRNAs in symptomatic patients with AD from a cohort that also included healthy controls (HC) and patients with preclinical Alzheimer's disease (PAD) (cohort 1). Plasmas from subjects with Parkinson's disease (PD) were used to control for disease specificity...

Antigen uptake, processing and presentation by antigen presenting cells (APCs) are tightly coupled processes which consequently lead to the activation of innate and adaptive immune responses. However, the regulatory role of microRNA (miRNAs) in these critical pathways is poorly understood. In this study, we show that overexpression of miR-24, miR-30b and miR-142-3p attenuates uptake and processing of soluble antigen ovalbumin (Ova) in primary human macrophages and dendritic cells. MiRNA mimic transfected APCs exhibit defects in antigen presentation (Ova and CMV antigen) to CD4+ T-cells leading to reduced cell proliferation...

BACKGROUND: Immunoactivation is less evident in secondary progressive MS (SPMS) compared to relapsing-remitting disease. MicroRNA (miRNA) expression is integral to the regulation of gene expression; determining their impact on immune-related cell functions, especially CD4+ T cells, during disease progression will advance our understanding of MS pathophysiology. This study aimed to compare miRNA profiles of CD4+ T cells from SPMS patients to healthy controls (HC) using whole miRNA transcriptome next-generation sequencing (NGS)...

Radiation-induced genomic instability plays a vital role in carcinogenesis. Bod1 is required for proper chromosome biorientation, and Bod1 depletion increases premature chromatid separation. MiR-142-3p influences cell cycle progression and inhibits proliferation and invasion in cervical carcinoma cells. We found that radiation induced premature chromatid separation and altered miR-142-3p and Bod1 expression in 786-O and A549 cells. Overexpression of miR-142-3p increased premature chromatid separation and G2/M cell cycle arrest in 786-O cells by suppressing Bod1 expression...

Phagocytosis commences with particle internalization and culminates with the activation of innate and adaptive immune responses. However, the role of miRNAs in phagocytosis remains largely unknown. In this study, we examined the role of miR-24, miR-30b and miR-142-3p in Ab Fc receptor (FcR)-mediated phagocytosis by macrophages (MΦ) and dendritic cells (DC). The expression of these miRNAs was reduced following phagocytosis of both IgG-opsonized beads and Escherichia coli, indicating their regulatory role in the process...

Osteoarthritis (OA) is a degenerative joint disease characterized by articular cartilage degradation and joint inflammation in which microRNAs are significantly involved. Previous studies have reported that miR-142-3p is a novel mediator of inflammatory signaling pathways, but whether miR-142-3p regulates OA remains unknown. In this study, we aimed to investigate the potential role of miR-142-3p in OA and the underlying molecular mechanism. We showed that miR-142-3p was significantly reduced in the articular cartilage tissues from experimental OA mice...

The aim of this review is to discuss current findings regarding the roles of miRNAs in periodontal diseases and the potential use of saliva as a diagnostic medium for corresponding miRNA investigations. For periodontal disease, investigations have been restricted to tissue samples and five miRNAs, that is, miR-142-3p, miR-146a, miR-155, miR-203, and miR-223, were repeatedly validated in vivo and in vitro by different validation methods. Particularly noticeable are the small sample sizes, different internal controls, and different case definitions of periodontitis in in vivo studies...

Anti-apoptotic genes and apoptomiRs deregulated expression contribute to apoptosis resistance in chronic myeloid leukemia (CML) Bcr-Abl(+) cells. Here, the L-amino acid oxidase from Calloselasma rhodostoma (CR-LAAO) venom altered the apoptotic machinery regulation by modulating the expression of the miR-145, miR-26a, miR-142-3p, miR-21, miR-130a, and miR-146a, and of the apoptosis-related proteins Bid, Bim, Bcl-2, Ciap-2, c-Flip, and Mcl-1 in Bcr-Abl(+) cells. CR-LAAO is a potential tool to instigate apoptomiRs regulation that contributes to drive CML therapy...
