Background: Semaphorin-3A (Sema3A), as a secreted semaphorin, is an immune modulator molecule participating in the pathogenesis of autoimmune diseases. MicroRNAs (miRNAs) modulate the target-gene expression at the post-transcriptional level. It has been proposed that miRNAs may be crucial to the modulation of the function of semaphorins. Previous findings have proven that miR-497-5p is upregula...

Breast cancer is a complex genetic disease that has an average annual incidence of two million people and the second leading cause of death among women all over the world. Micro-RNAs are consistently reported to regulate gene expression in all cancers. The present study, the correlation between the expression of hsa-miR-490-5p and nuclear factor of activated T-cells 5 (NFAT5) in breast cancer w...

The aim of the study was to demonstrate that preterm birth (PTB) is associated with altered C19MC microRNA expression profile in placental tissues. Gene expression of 15 placental specific microRNAs (miR‑512‑5p, miR‑515‑5p, miR‑516‑5p, miR‑517‑5p, miR‑518b, miR‑518f‑5p, miR‑519a, miR‑519d, miR‑519e‑5p, miR‑520a‑5p, miR‑520h, miR‑524‑5p, miR‑525‑5p, miR‑526a and miR‑526b‑5p) was compared between...

BACKGROUND Immunochemical fecal occult blood test (iFOBT) is widely used for colorectal cancer screening; however, its sensitivity is insufficient. We recently reported a fecal microRNA (miRNA) test (FmiRT) to detect colorectal cancer. In this study, we investigated a new colorectal cancer screening method combining iFOBT and FmiRT to improve the sensitivity compared with iFOBT alone. METHODS...

The aim of the present study was to examine the hypothesis that miR-33-5p attenuates morphine state-dependent (StD) memory via the µ opioid receptor by regulating cyclic AMP response element-binding protein (CREB). The effects of post-training morphine and morphine StD memory and their interaction with pre-test naloxone were evaluated using a single-trial inhibitory avoidance paradigm. Then, th...

MicroRNA (miRNA) expression profiling of colorectal cancer (CRC) are often inconsistent among different studies. To determine candidate miRNA biomarkers for CRC, we performed an integrative analysis of miRNA expression profiling compared CRC tissues and paired neighboring noncancerous colorectal tissues. Using robust rank aggregation method, we identified a miRNA set of 10 integrated-signature ...

Mice lacking the p27(Kip1) Cdk inhibitor (Cdkn1b) exhibit increased susceptibility to lymphomas from the Maloney murine leukemia virus (M-MuLV), and exhibit a high frequency of viral integrations at Xpcl1 (Kis2), a locus on the X-chromosome. Xpcl1 encodes miR-106a~363, a cluster of microRNAs that are expressed in response to adjacent retroviral integrations. We report the first large-scale prof...

MicroRNA are short and non-coding RNA, 18-25 nucleotides in length. They produced at the early stage of viral infection. The roles played by cellular miRNAs miRNA-mediated gene-silencing COVID-19 epidemic period is critical order to develop novel therapeutics. We analyzed SARS-CoV-2 Surface Glycoprotein (S) nucleotide sequence originating from India as well Iran, Australia, Germany, Italy, Russ...
