Insights

The MYC oncoprotein drives cancer growth and is implicated in about 70% of human cancers. Inhibiting MYC shows significant anti-cancer effects with reversible impact on healthy tissues, making it a key therapeutic target.

Area of Science:

  • Oncology
  • Molecular Biology
  • Drug Discovery

Background:

  • The MYC oncoprotein is a critical regulator of cell proliferation, differentiation, and apoptosis.
  • Dysregulation of MYC is observed in approximately 70% of human cancers, contributing to tumor initiation and progression.

Purpose of the Study:

  • To review the functional and structural characteristics of the MYC protein.
  • To provide an overview of MYC interactors that modulate its oncogenic activity.
  • To summarize therapeutic strategies targeting MYC, including direct and indirect inhibition approaches.

Main Methods:

  • Literature review of MYC's role in cancer.
  • Analysis of MYC protein structure and function.
  • Overview of identified MYC interactors.
  • Summary of current and emerging MYC-targeting therapeutic strategies.

Main Results:

  • MYC controls fundamental cellular processes and its aberrant expression is a hallmark of many cancers.
  • In vivo studies demonstrate that MYC inhibition leads to significant anti-proliferative effects and tumor regression.
  • Targeting MYC presents a promising therapeutic window due to reversible effects on healthy tissues.

Conclusions:

  • MYC is a highly attractive therapeutic target for cancer treatment due to its central role in oncogenesis and the potential for selective inhibition.
  • Understanding MYC's interactome is crucial for developing effective strategies to abrogate its oncogenic functions.
  • Various approaches are being developed to directly or indirectly target MYC, offering new avenues for cancer drug development.

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...

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...

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...

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...

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:
