Insights

Cancer

Area of Science:

  • Oncology
  • Epigenetics
  • Molecular Biology

Background:

  • Cancer arises from aberrant epigenetic regulation of gene expression.
  • Epigenetics involves modifications to DNA or histones, altering phenotypes without changing the genome.
  • Reprogramming the cancer epigenome is crucial for effective cancer treatment and overcoming drug resistance.

Purpose of the Study:

  • To highlight epigenetic pathways implicated in cancer.
  • To discuss potential small molecule inhibitors and epidrugs targeting epigenetic modifications.
  • To explore novel therapeutic strategies including nanomaterials and imaging for enhanced cancer treatment.

Main Methods:

  • Review of current literature on epigenetic pathways in cancer.
  • Analysis of small molecule inhibitors targeting DNA methyltransferase and histone modification.
  • Discussion of emerging therapies utilizing nanomaterials and advanced imaging techniques.

Main Results:

  • Epigenetic drug development shows promise for cancer therapy.
  • Targeting cancer epigenetics faces challenges due to a lack of selective and effective small molecules.
  • Structural insights into novel drug discovery for epigenetic targets are crucial.

Conclusions:

  • Epigenetic reprogramming is a vital strategy in cancer therapy.
  • Development of targeted epidrugs, including small molecules, nanomaterials, and imaging agents, is essential.
  • Further research into structural aspects of novel epigenetic drugs will improve cancer treatment efficacy.

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...

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.

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...

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...
