Insights

Cancer drug resistance prevents tumor cell death, leading to treatment failure. Targeting apoptosis, the programmed cell death pathway, offers novel strategies to sensitize cancer cells to therapies.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Research

Background:

  • Chemotherapy resistance is a significant challenge in cancer treatment, with ~90% of metastatic cancer patients succumbing to the disease.
  • Drug resistance, whether intrinsic or acquired, impedes tumor cell apoptosis, leading to treatment failure.
  • Targeting the apoptotic pathway shows promise in preclinical models for sensitizing cancer cells.

Purpose of the Study:

  • To review the role of apoptosis in cancer and its dysregulation.
  • To discuss novel therapeutic strategies targeting the apoptotic machinery.

Main Methods:

  • Literature review of apoptosis mechanisms in cancer.
  • Analysis of therapeutic agents targeting apoptotic pathways.

Main Results:

  • Dysregulation of apoptosis is a key mechanism in cancer drug resistance.
  • Therapeutic strategies targeting apoptosis include small molecule inhibitors, antisense strategies, recombinant proteins, and antibodies.

Conclusions:

  • Targeting apoptosis represents a promising approach to overcome chemotherapy resistance.
  • Novel therapies aimed at key apoptotic components could improve cancer treatment outcomes.

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...
The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
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...
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,...

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...
