An Overview of the Epigenetic Modifications of Gene Expression in Tumorigenesis
The five leading causes of cancer-related deaths are lung (1,760,000 deaths), colorectal (862,000 deaths), stomach (783,000 deaths), liver (782,000 deaths), and breast (627,000 deaths) cancers. Epigenetic changes can alter chromatin compaction, leading to the regulation of geneexpression without changing the primary DNA sequence.Epigenetic mechanisms are normally involved incellular processes s...
متن کاملLong Non-coding RNA ZEB1-AS1 Promotes Tumorigenesis and Metastasis in Colorectal Cancer
Emerging evidence implicates that a large fraction of human genome was transcribed but the transcripts known as long non coding RNA are not translated into proteins. They are contributing in different cellular processes, including cellular proliferation and apoptosis. LncRNAs were found to play critical roles in many diseases and act as key regulators in malignancies. In this study, we investig...
متن کاملRNA modifications go viral
Viral life cycles are often coordinated by precise mechanisms that act on their RNA. For example, the microRNA miR-122 interacts with the viral RNA genome of hepatitis C virus (HCV) and is required for HCV replication [1]. In the past year, several groups have reported a new RNA regulatory control to viral infection—the posttranscriptional RNA modification N6methyladenosine (mA). This reversibl...
متن کاملQuantitative analysis of RNA modifications.
RNA modifications impact numerous cellular processes such as pre-mRNA splicing and protein synthesis. The elucidation of the mechanisms by which these modifications impact cellular processes necessitates the ability to both detect and quantify the presence of these modifications within RNA molecules. Here, we present a detailed procedure that allows the detection and quantification of RNA base ...
متن کاملSmall RNA-mediated epigenetic modifications in plants.
Epigenetic modifications in plants can be directed and mediated by small RNAs (sRNAs). This regulation is composed of a highly interactive network of sRNA-directed DNA methylation, histone, and chromatin modifications, all of which control transcription. Identification and functional characterization of components of the siRNA-directed DNA methylation pathway have provided insights into epigene...
