Insights

This review details how non-coding RNAs, like microRNAs and long non-coding RNAs, impact congenital heart diseases. Understanding these genetic and environmental factors is crucial for developing new treatments for cardiac defects.

Area of Science:

  • Developmental Biology
  • Genetics
  • Molecular Biology

Background:

  • Cardiovascular development involves intricate stages from heart tube formation to a four-chambered organ.
  • Congenital heart diseases arise from disruptions in these complex developmental processes.
  • Advances in molecular biology have significantly enhanced our understanding of cardiac morphogenesis and its genetic underpinnings.

Purpose of the Study:

  • To review the current knowledge on the role of non-coding RNAs in congenital heart diseases.
  • To highlight the specific functions of microRNAs and long non-coding RNAs in cardiac development and disease.

Main Methods:

  • Literature review of studies on non-coding RNAs and congenital heart diseases.
  • Analysis of genetic and molecular mechanisms underlying cardiac morphogenesis.
  • Synthesis of findings on the impact of environmental factors and post-transcriptional regulation.

Main Results:

  • Non-coding RNAs, including microRNAs and long non-coding RNAs, play critical roles in cardiovascular development.
  • These molecules are implicated in the pathogenesis of various congenital heart diseases.
  • Dysregulation of non-coding RNAs can arise from genetic and environmental influences.

Conclusions:

  • Non-coding RNAs represent a significant area of research in congenital heart disease.
  • Further investigation into microRNAs and long non-coding RNAs may reveal novel therapeutic targets.

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Ischemic Heart Disease: Overview01:17

Ischemic Heart Disease: Overview

Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Transfer RNA Synthesis02:36

Transfer RNA Synthesis

One of the unique features of tRNA is the presence of modified bases. In some tRNAs, modified bases account for nearly 20% of the total bases in the molecule. Altogether, these unusual bases protect the tRNA from enzymatic degradation by RNases.
Each of these chemical modifications is carried by a specific enzyme, post-transcription. All of these enzymes have unique base and site-specificity. Methylation, the most common chemical modification, is carried by at least nine different enzymes, with...

RNA Splicing01:32

RNA Splicing

Splicing is the process by which eukaryotic RNA is edited before its translation into protein. The RNA strand transcribed from eukaryotic DNA is called the primary transcript. The primary transcripts that become mRNAs are called precursor messenger RNAs (pre-mRNAs). Eukaryotic pre-mRNA contains alternating sequences of exons and introns. Exons are nucleotide sequences that code for proteins, whereas introns are the non-coding regions. In RNA splicing, introns are removed and exons are bonded...

RNA Stability01:53

RNA Stability

Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...
