With total dependence on the host cell, several viruses have adopted strategies to modulate the host cellular environment, including the modulation of microRNA (miRNA) pathway through virus-encoded miRNAs. Several avian viruses, mostly herpesviruses, have been shown to encode a number of novel miRNAs. These include the highly oncogenic Marek's disease virus-1 (26 miRNAs), avirulent Marek's dise...

BACKGROUND MicroRNAs (miRNAs) are short, noncoding RNAs that inhibit the expression of target genes that play roles in tumorigenesis. MiR-21, miR-31, and miR-184 are oncogenic miRNAs for head and neck squamous cell carcinoma (HNSCC). Factor-inhibiting hypoxia (FIH)-inducible factor is known to inactivate hypoxia-induced downstream effectors and is involved in HNSCC suppression. This study inves...
MicroRNAs (miRNAs) translationally repressing their target messenger RNAs due to their gene-regulatory functions play an important but not unexpected role in a tumour development. More surprising are the findings that levels of various miRNAs are well correlated with presence of specific tumours and formation of metastases. Moreover, these small regulatory molecules play a role in the resistanc...
MicroRNAs (miRNAs) are potent post-transcriptional regulators of gene expression. In mammalian cells, miRNAs typically suppress mRNA stability and/or translation through partial complementarity with target mRNAs. Each miRNA can regulate a wide range of mRNAs, and a single mRNA can be regulated by multiple miRNAs. Through these complex regulatory interactions, miRNAs participate in many cellular...
The last decade was taken by storm when the existence of a class of small (˜22nt long) non - coding RNA species, known as microRNAs (miRNAs) came into light. MicroRNAs are one of the most abundant groups of regulatory genes in multicellular organisms and play fundamental roles in many cellular processes. Among these, miRNAs have been shown to prevent cell division and drive terminal differentia...
Tumor suppressor genes (TSGs) are often concomitantly lost or mutated in human cancers and have been shown to act synergistically to promote tumorigenesis. In addition to genomic alterations, posttranscriptional regulation by microRNAs (miRNAs) represents another mechanism by which TSG expression is dysregulated in cancers. Although miRNAs that target critical TSGs such as PTEN or p53 have been...
