The present study aimed to elucidate the potential roles and regulatory mechanism of microRNA (miR)-574-3p in the development of chronic myeloid leukemia (CML). The expression of miR-574-3p in peripheral blood obtained from patients with CML was examined. Subsequently, miR-574-3p was overexpressed and suppressed in CML K562 cells to further investigate the effects of miR-574-3p on cell proliferation, and apoptosis. Furthermore, a luciferase reporter assay was performed to investigate whether interleukin-6 (IL-6) was a target of miR-574-3p...

INTRODUCTION: Amyloidosis is caused by dysregulation of protein folding resulting in systemic or organ specific amyloid aggregation. When affecting the heart, amyloidosis can cause severe heart failure, which is associated with a high morbidity and mortality. Different subtypes of cardiac amyloidosis exist e.g. transthyretin cardiac amyloidosis and senile cardiac amyloidosis. Today, diagnostics is primarily based on cardiac biopsies and no clinically used circulating blood-based biomarkers existing...

Intestinal-type gastric carcinoma exhibits a multistep carcinogenic sequence from adenoma to carcinoma with a gradual increase in genomic alterations. But the roles of microRNAs (miRNA) in this multistage cascade are not fully explored. To identify differentially expressed miRNA (DEM) during early gastric carcinogenesis, we performed miRNA microarray profiling with 24 gastric cancers and precursor lesions (7 early gastric cancer [EGC], 3 adenomas with high-grade dysplasia, 4 adenomas with low-grade dysplasia, and 10 adjacent normal tissues)...

Recent studies have demonstrated that exosomal microRNAs (miRNAs) have the potential of facilitating molecular diagnosis. Currently, little is known about the underlying mechanism behind late-onset acute graft-versus-host disease (LA GVHD). Identifying differentially expressed miRNAs in exosomes should be useful for understanding the role of miRNAs in this disease. This study was established to investigate the relevance of miRNAs in exosomes derived from patients developing LA GVHD after allogeneic hematopoietic stem cell transplantation (HSCT)...

Studying the profile of micro RNAs (miRs) elucidated the highest expressed miRs in hepatic differentiation. In this study, we investigated to clarify the role of three embryonic overexpressed miRs (miR-106a, miR-574-3p and miR-451) during hepatic differentiation of human umbilical cord derived mesenchymal stem cells (UC-MSCs). We furthermore, aimed to explore whether overexpression of any of these miRs alone is sufficient to induce the differentiation of the UC-MSCs into hepatocyte-like cells. UC-MSCs were transfected either alone or together with miR-106a, miR-574-3p and miR-451 and their potential hepatic differentiation and alteration in gene expression profile, morphological changes and albumin secretion ability were investigated...

Butyrate inhibits growth of lung cancer. However, the molecular mechanism is still unclear. Here we profiled miRNAs that responded to sodium butyrate(NaB) stimulation in A549 cells, a non-small cell lung cancer cell line, using microarray. We found 33 up-regulated microRNAs and 22 down-regulated microRNAs (log2 ≥1.5 folds, P-value <0.05). The expression of miR-3935, miR-574-3p, and miR-494-3p was confirmed by realtime qPCR. Then,we explored their potential targets of miR-3935 and miR-494-3p using long noncoding RNA(LncRNA) microarray...

OBJECTIVES: Phenotypic heterogeneity in familial Mediterranean fever (FMF) disease indicated that FMF is not a simple monogenic disease. Therefore it has been suggested that epigenetic factors can be one of the reason for the variations. We undertook this study to test potential involvement of miRNAs in the pathogenesis of FMF. METHODS: miRNA array was performed on whole blood RNA samples from 6 healthy controls (-/-), 6 FMF patients (M694V/M694V), 6 carriers who displayed the disease phenotype (M694V/-) and 6 healthy carriers (M694V/-)...

Currently, little is known about the interactions between microRNAs (miRNAs) and the PD-1/PD-L1 signaling pathway in chordoma, and data discussing the role of the immune milieu in chordoma prognosis are limited. We aimed to analyze the relationship between PD-L1, miR-574-3p, microenvironmental tumor-infiltrating lymphocytes (TILs) and clinicopathological features of spinal chordoma patients. PD-L1 expression and TILs (including Foxp3+ , CD8+ , PD-1+ and PD-L1+ ) were assessed by immunohistochemistry in tumor specimens of 54 spinal chordoma patients...

Senescence recapitulates the ageing process at the cell level. A senescent cell stops dividing and exits the cell cycle. MicroRNAs (miRNAs) acting as master regulators of transcription, have been implicated in senescence. In the current study we investigated and compared the expression of miRNAs in young versus senescent human fibroblasts (HDFs), and analysed the role of mRNAs expressed in replicative senescent HFL-1 HDFs. Cell cycle analysis confirmed that HDFs accumulated in G1 /S cell cycle phase. Nanostring analysis of isolated miRNAs from young and senescent HFL-1 showed that a distinct set of 15 miRNAs were significantly up-regulated in senescent cells including hsa-let-7d-5p, hsa-let-7e-5p, hsa-miR-23a-3p, hsa-miR-34a-5p, hsa-miR-122-5p, hsa-miR-125a-3p, hsa-miR-125a-5p, hsa-miR-125b-5p, hsa-miR-181a-5p, hsa-miR-221-3p, hsa-miR-222-3p, hsa-miR-503-5p, hsa-miR-574-3p, hsa-miR-574-5p and hsa-miR-4454...

MicroRNAs (miRNAs) and heterogeneous nuclear ribonucleoproteins (hnRNPs) are families of sequence-specific, posttranscriptional modulators of gene expression. Despite extensive mechanistic and functional studies on both regulatory classes, the interactions and crosstalk between them are largely unexplored. We have reported that competition between miR-297 and hnRNP L to bind a 3΄UTR-localized CA-rich element (CARE) of VEGFA mRNA regulates its translation. Here, we show that translation of VEGFA mRNA in human myeloid cells is dictated by a bi-directional interaction between miR-574-3p, a CA-rich microRNA, and hnRNP L...

Small cell lung cancer (SCLC) constitutes approximately 15% of all diagnosed lung cancers. SCLC is a particularly lethal malignancy, as the 2-year survival rate after appropriate treatment is less than 5%. The patients with SCLC have not been received a benefit of the recently developed molecular targeted treatment. Therefore, a new treatment strategy is necessary for the patients. The molecular mechanisms underlying the aggressiveness of SCLC cells and their development of treatment-resistance are still ambiguous...

Human osteosarcoma is the most common primary bone malignancy sarcoma that affects primarily children and people <20 years old. In the present study, it was demonstrated that miR-574-3p was downregulated in human osteosarcoma U2OS, SAOS and MG63 cells lines as well as in osteosarcoma tissue compared with the normal tissues. Downregulation of miR-574-3p by antisense miR-574-3p, inhibited cell growth and induced cell apoptosis. Overexpression of miR-574-3p by transfection with miR-574-3p mimics promoted the growth of U2OS cells...

The mechanisms that regulate miR-574-3p expression in cells remain elusive. In the present study, we used real-time PCR assay to demonstrate TGF-β1-induced miR-574-3p upregulation in AGS cells, which was inhibited by TGF-β receptor I inhibitor SB431542. We used a computer search to identify Smad binding sites upstream of the miR-574-3p precursor sequence. We demonstrated that silencing Smad4, but not Smad2 or Smad3, significantly inhibited the TGF-β1-induced miR-574-3p upregulation in AGS cells. Furthermore, TGF-β1 significantly increased the activity of a dual-luciferase reporter that contains the Smad binding sites upstream of the miR-574 precursor sequence...

Follicular variants of papillary thyroid carcinoma include encapsulated (with or without capsular/vascular invasion) and infiltrative forms, which have different clinical behaviors. The encapsulated forms that lack capsular invasion have an indolent clinical behavior that is similar to benign lesions; therefore, they were recently reclassified as 'noninvasive follicular thyroid neoplasms with papillary-like nuclear features' (NIFTPs). Because NIFTPs have nuclear features of papillary carcinomas, distinguishing between NIFTPs and infiltrative follicular variant of papillary thyroid carcinoma is almost impossible with cytological examination...

Acquisition of resistance to docetaxel (Doc) is one of the most important problems in treatment of breast cancer patients, but the underlying mechanisms are still not fully understood. In present study, Doc-resistant MDA-MB-231 and MCF-7 breast cancer cell lines (MDA-MB-231/Doc and MCF-7/Doc) were successfully established in vitro by gradually increasing Doc concentration on the basis of parental MDA-MB-231 and MCF-7 cell lines (MDA-MB-231/S and MCF-7/S). The potential miRNAs relevant to the Doc resistance were screened by miRNA microarray...

MicroRNAs were first discovered as small endogenous RNA molecules and some viruses have been reported to interact with host miRNAs. By investigating miRNA expression in serum derived from HBV-infected patients, we have clarified the relationship between miRNA expression and chronic HBV infection. Additionally, we demonstrate the use of miRNAs as both novel biomarkers and new therapies against HBV. We included the sera of 20 patients with chronic HBV infection, sera of 20 patients with HCV infection and sera of 10 healthy controls in this study...

BACKGROUND: Recently, we reported signs of inflammation (raised IL-8, reduced miR-146a) and signs of vascular repair (raised HGF) in the serum of Ecuadorian patients with type 2 diabetes (T2D). In contrast, we found that the circulating monocytes lacked up-regulation of classical inflammatory genes (IL-1B, IL-6, and TNF) and there was even significant down-regulation of PTGS2. Notably, genes and a microRNA involved in adhesion, cell differentiation and morphology (CD9, DHRS3, PTPN7 and miR-34c-5p) were up-regulated in the T2D monocytes, suggesting a role of the anti-inflammatory cells in adhesion, vascular repair and invasion...
