abstract        background and objective: various cellular factors affect the process of hiv activity. one of these cellular factors are structures known as microrn that are expected to be involved in controlling hiv replication and infectivity. the expression of one or a set of them may represent the patient's clinical conditions. in this study,  the expression of mir-29a and mir-29b invo...

MicroRNA controls cancer invasion by governing the expression of gene regulating migration and invasion. Here, we reported a novel regulatory pathway controlled by miR-744-3p, which enhanced expression of matrix metallopeptidase 9 (MMP-9) in laryngeal squamous cell carcinoma (LSCC). We profiled the differential micoRNA expression pattern in LSCC cell lines and normal epithelial cultures derived...

Emerging evidence has shown that aberrant microRNA expression has the potential to be used for predicting survival and treatment response of malignant neoplasms. In recent years, the role of miR-9 had been investigated in various types of cancers, and it was found that the results were inconsistent and inconclusive. Hence, in this study, a meta-analysis was conducted to assess the prognostic va...

Hepatocellular carcinoma (HCC) is one of the most prevalent and lethal human cancers chronic hepatitis B virus (HBV) infection accounts for up to 50% total HCC cases worldwide. Although resection surgery has been available as a curative therapy HCC, high rate recurrence remains big threat patient survival. Therefore, discovery valuable biomarkers selecting patients at higher risk key goal allow...

OBJECTIVES MicroRNAs (miRNAs) are a class of short RNAs that control the biological processes including cell proliferation, apoptosis and development. Aberrant expression of miRNAs was determined in the different stages of tumor development and metastasis. To study the effect of silibinin on miRNAs expression, we evaluated quantitative expression of miR-21 and miR-155 as two oncomiRs and severa...

BACKGROUND MicroRNAs (miRNAs) are endogenous small (19-24 nt long) noncoding RNAs that regulate gene expression in a sequence specific manner. An increasing association between miRNA and cancer has been recently reported. Hepatocellular carcinoma (HCC), as the fifth most common cancer and the most common cause of death in men, has become the third leading cause of cancer-related deaths globally...

Recent studies revealed that different microRNA-9 (miR-9) expressions were associated with prognoses of different cancers. We conducted this meta-analysis to evaluate the prognostic value of miR-9. PubMed, Embase, Web of Science, and Cochrane Library (last update by November 30, 2015) were searched for literatures. A total of 17 studies from 16 articles were finally qualified and enrolled in th...

We have developed an in situ hybridization procedure for the detection of microRNAs (miRNAs) in tissue sections from mouse embryos and adult organs. The method uses highly specific washing conditions for RNA oligonucleotide probes conjugated to a fluorescein hapten. We show that this method detects predominantly mature miRNAs rather than the miRNA precursors or primary transcripts. We have dete...

Directed reprogramming of human fibroblasts into fully differentiated neurons requires massive changes in epigenetic and transcriptional states. Induction of a chromatin environment permissive for acquiring neuronal subtype identity is therefore a major barrier to fate conversion. Here we show that the brain-enriched miRNAs miR-9/9∗ and miR-124 (miR-9/9∗-124) trigger reconfiguration of chromati...
