Insights

Acquired resistance to tyrosine kinase inhibitors is a major challenge in cancer therapy. This review highlights recent molecular mechanisms driving this resistance, aiding in developing more effective anti-cancer treatments.

Area of Science:

  • Oncology
  • Molecular Biology
  • Pharmacology

Background:

  • Tyrosine kinases (TKs) are crucial regulators of cancer cell growth and survival.
  • Targeting TKs with therapies like monoclonal antibodies and small molecule inhibitors has shown success.
  • Acquired resistance to these TK-targeting drugs is a significant clinical problem.

Purpose of the Study:

  • To review the latest molecular mechanisms of acquired resistance to tyrosine kinase inhibitors.
  • To provide insights for developing novel anti-cancer therapies that overcome drug resistance.

Main Methods:

  • Review of recent preclinical studies.
  • Analysis of in vitro models of cancer.
  • Examination of patient samples to identify resistance mechanisms.

Main Results:

  • Identified several recently discovered molecular mechanisms underlying acquired resistance to TKIs.
  • Demonstrated that cancer cells develop diverse strategies to evade TKI activity.

Conclusions:

  • Understanding these resistance mechanisms is vital for improving cancer treatment outcomes.
  • Future therapies should aim to prevent or overcome acquired resistance to TKIs.

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 specific...
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 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...
Receptor Tyrosine Kinases01:26

Receptor Tyrosine Kinases

Receptor tyrosine kinases or RTKs are membrane-bound receptors that phosphorylate specific tyrosine on protein substrates. RTKs regulate cellular growth, differentiation, survival, and migration. They contain an extracellular ligand binding domain, a transmembrane domain, and a cytosolic tail with intrinsic kinase activity. Several extracellular signaling molecules activate RTKs in one or more ways and relay the signal downstream. Ligands such as platelet-derived growth factor (PDGF) or...

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...
