Insights

Inhibitors of apoptosis proteins (IAPs) are key regulators of cell processes implicated in cancer. Targeting IAPs shows promise for new anticancer therapies, with several drug candidates in clinical trials.

Area of Science:

  • Molecular Biology
  • Oncology
  • Biochemistry

Background:

  • Inhibitors of apoptosis proteins (IAPs) regulate critical cellular functions, including cell death, proliferation, and migration.
  • IAP overexpression is observed in various human tumors, correlating with tumor progression and poor treatment response.
  • IAPs can be rapidly induced by chemotherapy/radiotherapy via IRES-dependent translation, potentially causing therapeutic resistance.

Purpose of the Study:

  • To review the multifaceted role of IAPs in tumor development and progression.
  • To discuss the development of IAP-targeting molecules as a therapeutic strategy against cancer.
  • To highlight the current status of IAP antagonists in clinical trials.

Main Methods:

  • Literature review of studies on IAPs in cancer.
  • Analysis of IAP expression patterns in human tumor samples.
  • Examination of mechanisms underlying IAP-mediated chemoresistance.
  • Overview of preclinical and clinical development of IAP antagonists.

Main Results:

  • IAPs play a significant role in promoting tumor growth, survival, and metastasis.
  • IAP overexpression is a validated biomarker for poor prognosis in several cancers.
  • IAP antagonists have demonstrated potential in preclinical models and are advancing in clinical trials.

Conclusions:

  • IAPs represent a promising therapeutic target for novel anticancer strategies.
  • Targeting IAPs may overcome resistance mechanisms and improve treatment outcomes.
  • The ongoing clinical evaluation of IAP antagonists is crucial for their future application in oncology.

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 specific...

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:
Protein Networks02:26

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...
PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a rapamycin-insensitive companion...

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...
