MicroRNAs (miRNAs) are important post-transcriptional regulators involved in animal adipogenesis, however, their roles in bovine fat deposition remain poorly understood. In the present study, we conducted a comparative RNA sequencing to identify the key miRNAs involved in beef lipid accumulation by comparing the backfat small RNA samples between Wagyu (high intramuscular fat) and Holstein (moderate intramuscular fat) cattle. Fifteen miRNAs such as bta-miR-142-3p, bta-miR-379, bta-miR-196a, bta-miR-196b, bta-miR-30f and bta-miR-2887 were identified to have a higher expression level in Wagyu cattle compared with Holstein, whereas bta-miR-320a, bta-miR-874 and bta-miR-1247-3p had a lower expression level in Wagyu...

Functional microRNA (miRNA) molecules are transported in extracellular vesicles among tumor cells and cells of the immune system. Macrophages as integral components of tumor microenvironment are known as potential contributors to tumor growth and progression. We searched for studies which could provide a direct link between the particular miRNAs transported between cancer cells and macrophages and experimental evidence of subsequent alterations in biological functions of target cells. The validated targets of such microRNAs were found using miRWalk database...

BACKGROUND: Colorectal cancer (CRC) is one of the most common causes of cancer-related mortality worldwide. Early diagnosis of this neoplasm is critical and may reduce patients' mortality. MicroRNAs are small non-coding RNA molecules whose expression pattern can be altered in various diseases such as CRC. METHODS: In this study, we evaluated the expression levels of miR-142-3p, miR-26a-5p (their reduced expression in plasma samples of CRC patients was previously confirmed), miR-4478 and miR-1295-3p (their reduced expression in stool samples of CRC patients was previously confirmed) in tissue samples of CRC patients in comparison to healthy subjects...

Packaging of small molecular factors, including miRNAs, into small extracellular vesicles (SEVs) may contribute to malignant phenotypes and facilitate communication between cancer cells and tumor stroma. The process by which some miRNAs are enclosed in SEVs is selective rather than indiscriminate, with selection in part governed by specific miRNA sequences. Herein, we describe the selective packaging and removal via SEVs of four miRNAs (miR-142-3p, miR-150-5p, miR-451a, and miR-223-3p) in a panel of oral dysplasia and oral squamous cell carcinoma cell lines...

BACKGROUND: Identifying non-invasive and reliable blood-derived biomarkers for early detection of acute cellular rejection in heart transplant recipients is of great importance in clinical practice. MicroRNAs are small molecules found to be stable in serum and their expression patterns reflect both physiological and underlying pathological conditions in human. METHODS: We compared a group of heart transplant recipients with histologically-verified acute cellular rejection (ACR, n = 26) with a control group of heart transplant recipients without allograft rejection (NR, n = 37) by assessing the levels of a select set of microRNAs in serum specimens...

Sporadic tumors of the pituitary, parathyroids and adrenal cortex are unique, as their benign forms are very common, but malignant forms are exceptionally rare. Hereditary forms of these tumors occur in multiple endocrine neoplasia syndrome type 1 (MEN1). We hypothesize that the pathogenic link among the sporadic tumors of these organs of different germ layers might be represented by common molecular pathways involving the MEN1 gene and microRNAs (miR). miR-24 might be a microRNA linking the three tumor entities, but other candidates such as miR-142-3p and microRNAs forming the DLK1-MEG3 miRNA cluster might also be of importance...

MicroRNAs (miRNA) play an important role in post-transcriptional gene regulation of several physiological and pathological processes. In multiple sclerosis (MS), a chronic inflammatory and degenerative disease of the CNS, and in its mouse model, the experimental autoimmune encephalomyelitis (EAE), miRNA dysregulation has been mainly related to immune system dysfunction and white matter (WM) pathology. However, little is known about their role in gray matter pathology. Here, we explored miRNA involvement in the inflammation-driven alterations of synaptic structure and function, collectively known as synaptopathy, a neuropathological process contributing to excitotoxic neurodegeneration in MS/EAE...

AIMS: Exosome-mediated microRNA transfer is a recently discovered mode of cell-to-cell communication, in which microRNAs act as paracrine molecules, exerting their regulatory effects in recipient cells. T cells and endothelial cells are two main players in the mechanism of acute cellular cardiac rejection. The aim of this study was to investigate the role of exosomal microRNAs in the crosstalk between T cells and endothelial cells and its implications for the molecular mechanisms that drive acute cellular rejection in heart transplantation...

BACKGROUND: Over the last years, our knowledge on pathogenesis of gastric MALT lymphoma has greatly improved, but its morphological diagnosis is still hampered by overlapping histological features with advanced chronic gastritis. MicroRNAs are deregulated in lymphomas, but their role and usefulness in gastric MALT lymphoma has not been extensively investigated. MATERIALS AND METHODS: We analyzed the expression of 384 miRNAs using TaqMan microRNA assay in a training series of 10 gastric MALT lymphomas, 3 chronic gastritis and 2 reactive lymph nodes...

Myocardial ischemia/reperfusion (I/R) injury may cause the apoptosis of cardiomyocytes as well as cardiac fibrosis, which is characterized as the transdifferentiation of fibroblasts to myofibroblasts and collagen deposition. MicroRNAs (miRNAs or miRs) have been demonstrated to be involved in myocardial I/R injury. However, the underlying molecular mechanism remains largely unclear. In the present study, mouse cardiomyocyte M6200 cells were treated with hypoxia/reoxygenation (H/R). Our data indicated that H/R treatment led to cell apoptosis, the increased expression of fibrosis‑related proteins, namely collagen I, II, III, and fibronectin, as well as the downregulation of miR-142-3p in M6200 cells...

Regulatory CD4+ T cells (Tregs) are pivotal for prevention of autoimmunity. The use of Tregs is therefore of increasing interest in in vitro drug screening assays as well as for a cytotherapy per se against autoimmune disorders. For both purposes, in vitro expansion of peripheral blood Tregs is necessary and there is an increasing need to identify novel markers that can discriminate natural thymic derived Tregs (tTregs) from other T cell subsets and ideally, such markers should be stably expressed during in vitro expansion procedures...

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 past 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 suggests 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...

Our objective was to identify suitable reference genes in serum miRNA for normalization and screen potential new biomarkers for osteoporosis diagnosis by a systematic study. Two types of osteoporosis models were used like as mechanical unloading and estrogen deficiency. Through a large-scale screening using microarray, qPCR validation and statistical algorithms, we first identified miR-25-3p as a suitable reference gene for both type of osteoporosis, which also showed stability during the differentiation processes of osteoblast and osteoclast...
