Emerging evidence indicates that microRNA control and modulate immunity. MicroRNA have not been investigated in acquired aplastic anemia, a T-cell-mediated immune disease. Analysis of 84 microRNA expression levels in CD4(+) and CD8(+) T cells of patients with aplastic anemia revealed concurrent down-regulation of miR-126-3p, miR-145-5p, miR-223-3p, and miR-199a-5p (>3-fold change, P<0.05) in bo...

BACKGROUND The objective of this study was to investigate the molecular mechanism of atrial fibrillation (AF), as well as the negative regulatory relationship between miR-29a-3p and CACNA1C. MATERIAL AND METHODS We searched the online miRNA database (www.mirdb.org) and identified the miR-29a-3p binding sequence within the 3'-UTR of the target gene, and then conducted luciferase assay to verify ...

AIMS To explore the expression of miR-24-3p in human arteries with arteriosclerosis obliterans (ASO) as well as the role of miR-24-3p in the pathogenesis of ASO. METHODS We used quantitative real-time PCR (qRT-PCR) and in situ hybridization to monitor miR-24-3p expression in human arteries. To investigate the effect of miR-24-3p on human arterial smooth muscle cells (HASMCs), we applied cell ...

MicroRNAs (miRNAs) regulate cell proliferation, apoptosis and carcinogenesis by targeting related mRNAs in different types of cancer. miR-331-3p has been found to regulate the development and progression of various types of cancer cells. However, little research has been conducted on the role of miR-331-3p in colorectal cancer (CRC). The present study aimed to explore the function of miR-331-3p...

MicroRNAs (miRNAs) play an essential role in the regulation of almost all the biological processes, including melanogenesis. MiR-27a-3p is nearly six times higher in white alpaca skin compared to brown skin, which indicates that miR-27a-3p may be a candidate regulator for melanogenesis. Wnt3a plays an important role in promoting melanoblasts to differentiate into melanocytes and melanogenesis. ...

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 he...

BACKGROUND/AIMS Wnt/β-catenin pathway is involved in liver fibrosis and microRNAs (miRNAs) are considered as key regulators of the activation of hepatic stellate cells (HSCs). A recent study showed the protective role of miR-378a-3p against cardiac fibrosis. However, whether miR-378a-3p suppresses Wnt/β-catenin pathway in liver fibrosis is largely unknown. METHODS miR-378a-3p expression was d...

MicroRNAs (miRNAs) play a critical role in controlling tumor invasion and metastasis via regulating the expression of a variety of targets, which act as oncogenes or tumor suppressor genes. Abnormally expressed miR-625-3p has been observed in several types of human cancers. However, the molecular mechanisms of miR-625-3p-mediated tumorigenesis are largely elusive. Therefore, the aim of this stu...

Limited microRNAs (miRNAs, miRs) have been reported to be necessary for exercise-induced cardiac growth and essential for protection against pathological cardiac remodeling. Here we determined members of the miR-17-92 cluster and their passenger miRNAs expressions in two distinct murine exercise models and found that miR-17-3p was increased in both. miR-17-3p promoted cardiomyocyte hypertrophy,...

OBJECTIVE The aim of the current study was to elucidate the role of miR-455-3p in the pathogenesis of esophageal squamous cell carcinoma (ESCC) and its prognostic value in patients with ESCC. PATIENTS AND METHODS Expression levels of miR-455-3p and FAM83F mRNA in ESCC tissues and adjacent normal tissues were detected by quantitative RT-PCR. The X2-test was used to assess miR-455-3p expression...
