Single nucleotide polymorphisms (SNPs) in microRNAs (miRNAs) or their target sites (miR-SNPs) within the 3'-UTR of mRNAs are increasingly thought to play a major role in pathological dysregulation of gene expression. Here, we studied the functional role of miR-SNPs on miRNA-mediated post-transcriptional regulation of gene expression. First, analyses were performed on a SNP located in the miR-15...

MOTIVATION Circular RNAs (circRNAs) are an abundant class of highly stable RNAs that can affect gene regulation by binding and preventing microRNAs (miRNAs) from regulating their messenger RNA (mRNA) targets. Mammals have thousands of circRNAs with predicted miRNA binding sites, but only two circRNAs have been verified as being actual miRNA sponges. As it is unclear whether these thousands of p...

MicroRNAs (miRNAs) are involved in post-transcriptional regulation of gene expression through binding to messenger RNAs (mRNA) thereby promoting mRNA degradation or altered translation. A single-nucleotide polymorphism (SNP) located within a miRNA-binding site could thus alter mRNA translation and influence cancer risk and treatment response. The common SNPs located within the 3'-untranslated r...

Aims: MicroRNAs (miRNAs) binds to the 3’-untranslated regions (UTRs) of messenger RNAs and regulates cell differentiation, apoptosis and tumor genesis. Genetic polymorphisms at the 3’-UTRs alter the strength of miRNA binding and affect the behavior of miRNA. In this study, we analyzed a single-nucleotide polymorphism (SNP) of rs11337 within the miRNA seed region for the 3’-UTR of GOLGA7 gene to...

Second primary tumor (SPT) and/or recurrence negatively impact the prognosis of patients with curatively treated early-stage head and neck cancer. MicroRNAs (miRNAs) play important roles in cancer development. We explored whether the variations of miRNA-related pathway were associated with the risk of SPT/recurrence in patients with early-stage head and neck cancer. This study includes 150 earl...

MicroRNAs (miRNAs) are a class of noncoding small RNAs that regulate gene expression by base pairing with target mRNAs at the 3'-terminal untranslated regions (3'-UTRs), leading to mRNA cleavage or translational repression. Single-nucleotide polymorphisms (SNPs) located at miRNA-binding sites (miRNA-binding SNPs) are likely to affect the expression of the miRNA target and may contribute to the ...

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...

Alzheimer's disease (AD) is a multifactorial resulting from both genetic and environmental factors, which are pathologically defined by the accumulation of intracellular hyperphosphorylated tau protein, neurofibrils tangles, extracellular amyloid β protein in brain. The purpose this study to estimate potentially damaging effects missense single nucleotide polymorphisms (SNPs) BID, MAPK10 AGER g...
