Insights

MYC oncogene inhibition is crucial for cancer treatment. New strategies target MYC indirectly by stabilizing its structure or inhibiting related proteins, offering promising clinical applications.

Area of Science:

  • Oncology
  • Molecular Biology
  • Medicinal Chemistry

Background:

  • The MYC oncogene is frequently activated in human cancers, making it a critical therapeutic target.
  • Direct inhibition of MYC is challenging due to its disordered structure and lack of a defined binding site.
  • Recent advances in structural biology and computational tools enable novel indirect targeting strategies.

Purpose of the Study:

  • To review small molecules developed for indirect MYC inhibition strategies.
  • To discuss emerging targets for MYC-directed cancer therapies.

Main Methods:

  • Review of literature on small molecules targeting MYC.
  • Analysis of strategies including MYC guanine quadruplex stabilization, BET factor inhibition, and MYC:MAX heterodimer disruption.
  • Discussion of novel protein-level targets for indirect MYC inhibition.

Main Results:

  • Several small molecules have been developed for clinical applications targeting MYC indirectly.
  • Strategies include stabilizing the MYC guanine quadruplex, inhibiting BRD4, and disrupting the MYC:MAX complex.
  • Novel protein targets for indirect MYC inhibition have been identified.

Conclusions:

  • Indirect targeting strategies offer viable clinical approaches for MYC-driven cancers.
  • The development of small molecules for these strategies is advancing cancer therapeutics.
  • Continued research into novel targets will further enhance MYC-directed cancer interventions.

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...

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

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...

Mouse Models of Cancer Study02:43

Mouse Models of Cancer Study

Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

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...
