Insights

Atherosclerosis, a key factor in cardiovascular diseases (CVD), involves gene regulation by transcription factors and epigenetics. Understanding their crosstalk offers novel therapeutic strategies for CVD.

Area of Science:

  • Cardiovascular Science
  • Molecular Biology
  • Genetics

Background:

  • Cardiovascular diseases (CVD) are the leading global cause of mortality.
  • Atherosclerosis, a vascular inflammatory disease, is a major contributor to CVD.
  • Gene expression regulation by transcription factors and epigenetic mechanisms is crucial in atherosclerosis development.

Purpose of the Study:

  • To review the underappreciated crosstalk between transcription factors and epigenetic mechanisms in atherosclerosis.
  • To highlight novel therapeutic strategies targeting these mechanisms for CVD treatment.

Main Methods:

  • Literature review of studies on gene regulation in atherosclerosis.
  • Analysis of the interaction between transcription factors and epigenetic modifiers.
  • Exploration of potential therapeutic targets in atherosclerotic CVD.

Main Results:

  • Transcription factors and epigenetic mechanisms play fundamental roles in atherosclerosis.
  • Crosstalk between these factors is critical but understudied in CVD.
  • Chromatin remodeling offers potential therapeutic avenues for CVD.

Conclusions:

  • Understanding the interplay between transcription factors and epigenetics is key to developing novel CVD therapeutics.
  • Targeting epigenetic modifiers and transcription factors holds promise for combating atherosclerotic CVD.

Epigenetic Regulation

Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

General Transcription Factors01:30

General Transcription Factors

Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...

RNA Polymerase II Accessory Proteins

Proteins that regulate transcription can do so either via direct contact with RNA Polymerase or through indirect interactions facilitated by adaptors, mediators, histone-modifying proteins, and nucleosome remodelers. Direct interactions to activate transcription is seen in bacteria as well as in some eukaryotic genes. In these cases, upstream activation sequences are adjacent to the promoters, and the activator proteins interact directly with the transcriptional machinery. For example, in...

Master Transcription Regulators02:23

Master Transcription Regulators

Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a  complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

Co-activators and Co-repressors02:04

Co-activators and Co-repressors

Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...
