Insights

Cancer involves genetic mutations and reversible epigenetic changes. Targeting epigenetic mechanisms like DNA methylation and histone modifications offers potential for new cancer therapies.

Area of Science:

  • Oncology
  • Molecular Biology
  • Epigenetics

Background:

  • Tumorigenesis and metastasis arise from genetic alterations, including mutations in tumor suppressor genes and oncogenes.
  • Epigenetic changes, which modify gene function without altering DNA sequence, also play a crucial role in cancer development.
  • These epigenetic modifications can be reversible, presenting unique therapeutic opportunities.

Purpose of the Study:

  • To review the role of epigenetic alterations in cancer.
  • To explore the potential of targeting reversible epigenetic processes for cancer therapy.

Main Methods:

  • Review of scientific literature on epigenetics and cancer.
  • Analysis of epigenetic mechanisms such as DNA methylation and histone modifications (acetylation, methylation, phosphorylation).

Main Results:

  • Cancer cells exhibit altered epigenetic mechanisms, including aberrant DNA methylation and histone modifications.
  • Mutations in genes influencing epigenetic processes can disrupt normal gene expression programs.
  • Epigenetic modifications are implicated in the progression of tumorigenesis and metastasis.

Conclusions:

  • Reversible epigenetic processes are critical in cancer development.
  • Targeting epigenetic mechanisms represents a promising strategy for novel cancer therapies.

Histone Variants at the Centromere02:30

Histone Variants at the Centromere

Histone variants are the histone proteins with structural and sequence variations. These variants may be regarded as “mutant” forms that replace their canonical histone counterparts in the nucleosomes. Specific post-translational modifications on the histone variants enable further chromatin complexity and regulate tissue-specific gene expression. The most common histone variants are from histone H2A, H2B, and linker histone H1 families. However, several variants of histone H3 variants are also...
Histone Modification02:32

Histone Modification

The histone proteins have a flexible N-terminal tail extending out from the nucleosome. These histone tails are often subjected to post-translational modifications such as acetylation, methylation, phosphorylation, and ubiquitination. Particular combinations of these modifications form “histone codes” that influence the chromatin folding and tissue-specific gene expression.
Acetylation
The enzyme histone acetyltransferase adds acetyl group to the histones. Another enzyme, histone deacetylase,...

Spreading of Chromatin Modifications02:25

Spreading of Chromatin Modifications

The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...
