Insights

Epigenetic alterations drive cancer development and resistance. Targeting these reversible changes with novel epigenetic drugs (epidrugs) offers a promising therapeutic strategy in oncology.

Area of Science:

  • Oncology
  • Epigenetics
  • Molecular Biology

Background:

  • Epigenetic dysregulation is a hallmark of cancer, influencing carcinogenesis from initiation to treatment resistance.
  • Epigenetic alterations are frequent, relevant, and reversible, making them attractive therapeutic targets.

Purpose of the Study:

  • To review the primary epigenetic mechanisms regulating gene expression.
  • To summarize current knowledge on available epigenetic drugs (epidrugs).
  • To focus on epidrug mechanisms of action and clinical trial status.

Main Methods:

  • Scoping review methodology.
  • Literature search for epigenetic mechanisms and epidrugs.
  • Analysis of drug mechanisms and clinical trial data.

Main Results:

  • Overview of key epigenetic regulatory mechanisms.
  • Identification of currently available epidrugs.
  • Summary of ongoing clinical trials investigating epidrugs.

Conclusions:

  • Epigenetic therapies are advancing with improved specificity and reduced toxicity.
  • Targeting epigenetic alterations represents a significant therapeutic avenue in cancer treatment.
  • Further research and clinical trials are crucial for optimizing epidrug efficacy.

Epigenetic Regulation

Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Toxicological Assays for Testing Effects of an Epigenetic Drug on Development, Fecundity and Survivorship of Malaria Mosquitoes

A protocol is developed to examine the effects of an epigenetic drug DZNep on the development, fecundity and survivorship of mosquitoes. Here we describe procedures for the aqueous exposure of DZNep to immature mosquitoes and a blood-based exposure of DZNep to adult mosquitoes in addition to measuring SAH hydrolase inhibition.

An Overview of Epigenetics

Since the early days of genetics research, scientists have noted certain heritable phenotypic differences that are not due to differences in the nucleotide sequence of DNA. Current evidence suggests that these “epigenetic” phenomena might be controlled by a number of mechanisms, including the modification of DNA cytosine bases with methyl groups, the addition of various chemical groups to histone proteins, and the recruitment of protein factors to specific DNA sites via interactions...
