Plant non-coding RNAs and epigenetics

Non-coding RNAs as regulators of gene expression and epigenetics.

Genome-wide studies have revealed that mammalian genomes are pervasively transcribed. This has led to the identification and isolation of novel classes of non-coding RNAs (ncRNAs) that influence gene expression by a variety of mechanisms. Here we review the characteristics and functions of regulatory ncRNAs in chromatin remodelling and at multiple levels of transcriptional and post-transcriptio...

Long non-coding RNAs and their implications in cancer epigenetics

LncRNAs (long non-coding RNAs) have emerged as key molecular players in the regulation of gene expression in different biological processes. Their involvement in epigenetic processes includes the recruitment of histone-modifying enzymes and DNA methyltransferases, leading to the establishment of chromatin conformation patterns that ultimately result in the fine control of genes. Some of these g...

The Role of Long Non-Coding RNAs in Ovarian Cancer

Background: Ovarian cancer is the most fatal tumor of female's reproductive system, and several genetics and environmental factors are involved in its development. Various studies have already identified suitable biomarkers to facilitate the early detection, prognosis evaluation, and the assessment of treatment response. However, the aim of this review was to investigate the role of long non-co...

Small Non-Coding RNAs in Plant Immunity

Long non-coding RNAs and their significance in human diseases

Protein-coding genes account for only a small fraction of the human genome and most of the genomic sequences are transcriptionally silent, but recent observations indicate significant functional elements, including non-coding protein transcripts in the human genome. Long non-coding RNAs (lncRNAs) have been defined as transcripts of >200 nucleotides without protein-coding capacity that perform t...
