  • Molecular Biology

Background:

  • Cancer is characterized by uncontrolled malignant cell growth and significant molecular diversity, complicating treatment selection.
  • Cancer development involves a complex series of molecular events, prompting research into underlying processes.
  • Epigenetic mechanisms, specifically DNA methylation and histone modification, are increasingly recognized as critical contributors to oncogenesis.

Purpose of the Study:

  • To provide an overview of epigenetics in cancer, focusing on DNA methylation and histone modification.
  • To explore the potential of targeting epigenetic regulators as a therapeutic strategy for cancer treatment.
  • To summarize FDA-approved drugs targeting epigenetic enzymes and discuss challenges in developing epigenetic-based cancer therapeutics.

Main Methods:

  • Literature review focusing on epigenetic mechanisms in cancer.
  • Analysis of DNA methylation and histone modification pathways involved in tumorigenesis.
  • Summary of current FDA-approved drugs targeting epigenetic regulators in clinical use.

Main Results:

  • Epigenetic alterations, including aberrant DNA methylation and histone modifications, are hallmarks of cancer.
  • Targeting enzymes involved in DNA methylation and histone modification has shown efficacy in preclinical and clinical settings for various cancers.
  • Several FDA-approved drugs targeting epigenetic regulators are available, demonstrating the clinical relevance of this approach.

Conclusions:

  • Epigenetics plays a crucial role in cancer initiation and progression, making epigenetic regulators attractive therapeutic targets.

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...

Targets for Drug Action: Overview01:26

Targets for Drug Action: Overview

Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

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...

Cancer02:18

Cancer

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

Drug Discovery: Overview01:26

Drug Discovery: Overview

Drug discovery is a multifaceted process involving extensive screening, testing, and optimization of lead compounds to identify potential new drugs for therapeutic use. It combines several approaches, including screening large numbers of natural products, chemical modification of known active molecules, identification of new drug targets, and rational design based on biological mechanisms and drug-receptor structure. These approaches are carried out in both academic research laboratories and...
