Insights

Chromatin, a complex of DNA and proteins, plays a key role in gene expression and cancer. This review explores epigenetic modifications in cancer and promising therapeutic inhibitors.

Area of Science:

  • Epigenetics and Molecular Biology
  • Cancer Research

Background:

  • DNA is packaged into chromatin, a complex of DNA and proteins.
  • Chromatin structure and its alterations are crucial for gene expression control.
  • Epigenetic mechanisms like DNA methylation and histone modifications are implicated in various cancers.

Purpose of the Study:

  • To review alterations in gene expression and epigenetic modification patterns in cancer cells.
  • To identify key modulators and inhibitors of epigenetic mechanisms in cancer.
  • To analyze the molecular evolution of representative epigenetic inhibitors.

Main Methods:

  • Literature review of epigenetic alterations in cancer.
  • Analysis of gene expression changes and epigenetic modification patterns.
  • Examination of modulators, inhibitors, and molecular evolution of epigenetic drugs.

Main Results:

  • Significant alterations in gene expression and epigenetic patterns are observed in cancer cells.
  • Several epigenetic mechanisms, including DNA methylation and histone modifications, are critical in cancer development.
  • Specific inhibitors targeting histone acetyltransferases (HAT), histone deacetylases (HDAC), DNA methyltransferases (DNMT), and chromatin remodelers show therapeutic potential.

Conclusions:

  • Epigenetic modifications are central to cancer pathogenesis.
  • Targeting epigenetic mechanisms offers a promising therapeutic strategy for cancer treatment.
  • The development of HAT, HDAC, DNMT, and domain inhibitors represents a significant advancement in cancer therapy.

Epigenetic Regulation01:37

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.

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...

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
