Insights

Alternative splicing of apoptotic genes is crucial in heart disease development and progression. Aberrant splicing offers potential diagnostic markers and therapeutic targets for cardiovascular disorders.

Area of Science:

  • Molecular Biology
  • Cardiovascular Science
  • Genetics

Background:

  • Apoptosis is vital for heart development and implicated in heart disease.
  • Alternative splicing of apoptotic genes is an emerging area for cardiac disease research.

Purpose of the Study:

  • To review the role of aberrant alternative splicing of apoptotic genes in cardiac disorders.
  • To highlight the diagnostic and therapeutic potential of alternative splicing in heart disease.

Main Methods:

  • Literature review focusing on alternative splicing in apoptosis and cardiovascular diseases.
  • Analysis of Bcl-2 family alternative splicing and its functional implications.
  • Examination of altered transcript levels in diseased versus healthy hearts.

Main Results:

  • Alternative splicing of apoptotic genes, particularly Bcl-2 family members, is increased in cardiovascular diseases.
  • Alternatively spliced isoforms can inhibit pro-apoptotic functions, contributing to disease pathology.
  • Elevated alternate transcripts serve as potential diagnostic and prognostic indicators.

Conclusions:

  • Abnormal alternative splicing of apoptotic genes is implicated in cardiomyopathy, ischemia, and heart failure.
  • These splicing events can be causative or adaptive responses to cardiac pathology.
  • Targeting disease-related splicing events presents a promising therapeutic strategy for heart disease.

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...

Alternative RNA Splicing

Alternative RNA splicing is the regulated splicing of exons and introns to produce different mature mRNAs from a single pre-mRNA. Unlike in constitutive splicing where a single gene produces a single type of mRNA, alternative splicing allows an organism to produce multiple proteins from a single gene and plays an important role in protein diversity.
There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...

What is Gene Expression?

A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is comprised  of nucleotides and proteins are comprised of amino acids, a mediator is required to convert the information encoded in DNA into proteins. This mediator is the messenger RNA (mRNA). mRNA copies the blueprint from DNA by a process called transcription. In eukaryotes, transcription occurs in the nucleus by complementary base-pairing with the DNA template. The mRNA is then...

Chromatin Structure Regulates pre-mRNA Processing

In eukaryotic cells, nascent mRNA transcripts need to undergo many post-transcriptional modifications to reach the cell cytoplasm and translate into functional proteins. For a long time, transcription and pre-mRNA processing were considered two independent events that occur sequentially in the cell. However, it has now been well established that transcription and pre-mRNA processing are two simultaneous processes that are precisely regulated inside the cell.
The chromatin structure, especially...
