Insights

Targeted cancer therapies show promise but drug resistance limits effectiveness. Understanding genetic and non-genetic resistance mechanisms is key to developing new strategies for advanced cancer treatment.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Targeted cancer therapies exploiting genomic vulnerabilities are clinically validated.
  • Acquired drug resistance significantly limits the utility of these treatments, posing a clinical challenge.

Purpose of the Study:

  • To discuss genetic and non-genetic mechanisms of acquired drug resistance.
  • To explore emerging strategies for overcoming or preventing resistance to targeted therapies.

Main Methods:

  • Literature review of molecular mechanisms of drug resistance.
  • Analysis of genetic and non-genetic resistance pathways in targeted cancer therapy.

Main Results:

  • Drug resistance in cancer is acquired through both mutational (genetic) and non-mutational (potentially epigenetic) mechanisms.
  • Elucidation of resistance mechanisms is crucial for developing effective therapeutic strategies.

Conclusions:

  • Understanding diverse resistance mechanisms is essential for improving targeted cancer therapy outcomes.
  • Developing strategies to overcome acquired resistance is critical for managing advanced cancers.

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...
Adaptive Mechanisms in Cancer Cells02:53

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,...

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...

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...
