Hepatocellular carcinoma (HCC) remains a major health problem for delayed diagnosis, inefficient surveillance and poor prognosis. Recent studies have indicated that non-coding RNAs contribute to the development of new strategies for diagnosis and treatment of HCC. In the present study, we employed 18 pairs of HCC and matched non-tumor tissues for the identification of differentially expressed microRNAs (miRNAs) in HCC, among which 7 paired specimens were selected randomly for microarray detection. Totally, twenty-three miRNAs were screened out to have statistically significant differences with the threshold of P < 0...

Steroid-induced osteonecrosis of the femoral head (ONFH) is a common orthopedic disease. The lack of specific manifestations and effective diagnostic methods make it difficult for this disease to be diagnosed at early stages. Recent studies have shown that microRNAs (miRNA) participate in the development of steroid-induced ONFH, but there is limited research into the diagnostic use of circulating miRNAs. Blood samples from 23 human subjects (7 systemic lupus erythematosus (SLE) patients with steroid-induced ONFH; 7 SLE controls without ONFH; and 9 healthy controls) and 71 rats (19 with steroid-induced ONFH; 28 receiving steroids without ONFH; and 24 untreated controls) were collected to verify the abundance of changes of 6 previously identified ONFH-associated plasma miRNAs (miR-423-5p, miR-99a-5p, miR-10a-5p, miR-21-5p, miR-130a-3p and miR-6787-5p) by quantitative RT-PCR (Reverse Transcription-Polymerase Chain Reaction)...

BACKGROUND: Aging is one of the key factors that regulate the function of human bone marrow mesenchymal stem cells (hBM-MSCs) and related changes in microRNA (miRNA) expression. However, data reported on aging-related miRNA changes in hBM-MSCs are limited. METHODS: We demonstrated previously that miR-10a is significantly decreased in aged hBM-MSCs and restoration of the miR-10a level attenuated cell senescence and increased the differentiation capacity of aged hBM-MSCs by repressing Krüpple-like factor 4 (KLF4)...

Background -Alternative macrophage activation, which relies on mitochondrial oxidative metabolism, plays a central role in resolution of inflammation and prevents atherosclerosis. Moreover, macrophages handle large amounts of cholesterol and triglycerides derived from the engulfed modified lipoproteins during atherosclerosis. Although several microRNAs regulate macrophage polarization, the role of microRNA-generating enzyme Dicer in macrophage activation during atherosclerosis is unknown. Methods -To evaluate the role of Dicer in atherosclerosis, Apoe-/- mice with or without macrophage-specific Dicer deletion were fed a high-fat diet for 12 weeks...

Frailty is a geriatric syndrome associated with progressive physical decline and significantly increases risk for falls, disability, hospitalizations, and death. However, much remains unknown regarding the biological mechanisms that contribute to aging and frailty, and to date, there are no clinically used prognostic or diagnostic molecular biomarkers. The present study profiled exosome-derived microRNAs isolated from the plasma of young, robust older, and frail older individuals and identified eight miRNAs that are uniquely enriched in frailty: miR-10a-3p, miR-92a-3p, miR-185-3p, miR-194-5p, miR-326, miR-532-5p, miR-576-5p, and miR-760...

Myelopoiesis involves differentiation of hematopoietic stem cells to cellular populations that are restricted in their self-renewal capacity, beginning with the common myeloid progenitor (CMP) and leading to mature cells including monocytes and granulocytes. This complex process is regulated by various extracellular and intracellular signals including microRNAs (miRNAs). We characterised the miRNA profile of human CD34+ CD38+ myeloid progenitor cells, and mature monocytes and granulocytes isolated from cord blood using TaqMan Low Density Arrays...

While immunosuppressive environments mediated by myeloid-derived suppressor cells (MDSCs) have been well documented in glioma patients, the mechanisms of MDSC development and activation have not been clearly defined. Here, we elucidated a role for glioma-derived exosomes (GDEs) in potentiating an MDSC pathway. We isolated normoxia-stimulated and hypoxia-stimulated GDEs and studied their MDSC induction abilities in vivo and in vitro. Analyses of spleen and bone marrow MDSC proportions (flow cytometry) and reactive oxygen species (ROS), arginase activity, nitric oxide (NO), T-cell proliferation and immunosuppressive cytokine (IL-10 and TGF-β, ELISA) levels were used to assess MDSC expansion and functional capacity...

BACKGROUND: Aneuploidy, or abnormal chromosome numbers, severely alters cell physiology and is widespread in cancers and other pathologies. Using model cell lines engineered to carry one or more extra chromosomes, it has been demonstrated that aneuploidy per se impairs proliferation, leads to proteotoxic as well as replication stress and triggers conserved transcriptome and proteome changes. RESULTS: In this study, we analysed for the first time miRNAs and demonstrate that their expression is altered in response to chromosome gain...

BACKGROUND: Anti-inflammatory drugs and DMARDs, especially methotrexate, have dramatically improved the outlook of RA patient. However, in some patients the treatment effect is still not satisfactory and needs to change therapeutic regimen in time. So, prediction of patient treatment effect timely is particularly important. METHODS: miRNAs are a large family of highly conserved noncoding genes and some of them become potential biomarker of disease diagnosis. In present study, we found circulating miR-10a was significantly decreased in RA patients compared to osteoarthritic patients and healthy people...

BACKGROUND: By regulating target genes, microRNAs play essential roles in carcinogenesis and drug resistance in human pancreatic ductal adenocarcinoma (PDAC). Previous studies have shown that microRNA-10a-5p (miR-10a-5p) is overexpressed in PDAC and acts as an oncogene to promote the metastatic behavior of PDAC cells. However, the role of miR-10a-5p in PDAC chemoresistance remains unclear. METHODS: The effects of miR-10a-5p on biological behaviors were analyzed...

MicroRNAs (miRs) have been demonstrated to perform important roles in normal hematopoiesis and leukemogenesis. Accumulating evidence suggests that miR-10a and miR-10b may behave as novel oncogenes or tumor suppressors in human cancer. The present study reported the function of the miR-10 family in myeloid differentiation and acute myeloid leukemia (AML). The levels of miR-10a/b expression were increased in AML cases compared with normal controls, particularly in M1, M2 and M3 subtypes. The levels of miR-10a/b expression were also upregulated in patients with nucleophosmin-mutated AML and AML patients with t(8;21) and t(9;11), compared with the normal control...

MicroRNAs (miRs) are expected to serve as prognostic tools for cancer. However, many miRs have been reported as prognostic markers of recurrence or metastasis in oral squamous cell carcinoma patients. We aimed to determine the prognostic markers in early-stage tongue squamous cell carcinoma (TSCC). Based on previous studies, we hypothesized that miR-10a, 10b, 196a-5p, 196a-3p, and 196b were prognostic markers and we retrospectively performed miR expression analyses using formalin-fixed paraffin-embedded sections of surgical specimens...
