BACKGROUND Aim to determine the clinicopathological and prognostic role of miR-301a-3p in pancreatic ductal adenocarcinoma(PDAC), to investigate the biological mechanism of miR-301a-3p in vitro and in vivo. METHODS By tissue microarray analysis, we studied miR-301a-3p expression in PDAC patients and its clinicopathological correlations as well as prognostic significance. qRT-PCR was used to t...

BACKGROUND Increasing evidence suggests that microRNAs (miRNAs) play critical roles in malignant transformation, tumor progression and metastasis. Aberrant miR-655-3p expression has been associated with several cancers. However, the role and underlying mechanism of miR-655-3p in the development of hepatocellular carcinoma (HCC) remains unclear. METHODS MiR-655-3p expression was detected by qu...

It has been demonstrated that the deregulation of microRNAs (miRNAs) affects the development of rheumatoid arthritis (RA). The primary objective of the current study was to determine the role of miR-143-3p in the progression of RA. The expression of miR-143-3p in synovium taken from patients with RA was assessed by reverse transcription-quantitative polymerase chain reaction. The expression of ...

microRNA-338-3p (miR-338-3p) has been implicated in tumor development and progression in many types of cancers. However, the function and mechanism underlying the action of miR-383-3p in thyroid cancer remain unclear and were therefore investigated in this study by in vitro and in vivo experiments. We found that miR-338-3p was downregulated in thyroid cancer tissues and cell lines. miR-338-3p e...

The fucosyltransferase (FUT) family produces glycans, a fundamental event in several cancers, including colorectal cancer (CRC). miR-125a-3p is a non-coding RNA that can reduce cell proliferation and migration in cancer. In this study, we explored the levels of miR-125a-3p and FUT expression in human CRC tissues and two human CRC cell lines by qPCR. The results showed that miR-125a-3p, FUT5 and...

BACKGROUND Clinically, prostate cancer (PCa) exhibits a high avidity to metastasize to bone. miR-141-3p is an extensively studied miRNA in cancers and downregulation of miR-141-3p has been widely reported to be involved in the progression and metastasis of several human cancer types. However, the clinical significance and biological roles of miR-141-3p in bone metastasis of PCa are still unclea...

This study aimed to elucidate how microRNA27a-3p (miR-27a-3p) modulates the Wnt/β-catenin signaling pathway to promote the epithelial-mesenchymal transition (EMT) in oral squamous carcinoma stem cells (OSCSCs) by targeting secreted frizzled-related protein 1 (SFRP1). Flow cytometry was used to sort OSCSCs from the SCC-9 and Tca8113 cell lines. The OSCSCs were randomly assigned into the miR-27a-...

The aims of the present study are to determine whether hydrogen sulfide (H2S) is involved in the expression of endothelial nitric oxide synthase (eNOS) and nitric oxide (NO) production, and to identify the role of microRNA-455-3p (miR-455-3p) during those processes. In cultured human umbilical vein endothelial cells (HUVECs), the expression of miR-455-3p, eNOS protein and the NO production was ...

Bladder cancer (BCa) is the one of the most common cancers with high incidence, occurrence and low 5-year survival rate. Emerging evidence indicates that DLK1-DIO3 genomic region especially the miRNA cluster in this region is involved in several pathologic processes and various cancers, and miR-323a-3p is a member of this miRNA cluster. In this study, we investigate the function and regulatory ...

The present study aimed to investigate the expression status of miRNA‑199a‑3p in patients with diabetic neuropathy (DN) and the mechanism by which this miRNA is involved in the genesis of DN. The expression of miRNA‑199a‑3p in plasma of peripheral blood was compared between patients with diabetes and a family history of diabetes and control volunteers by reverse transcription‑quantitative polym...
