Insights

Cancer cells survive by resisting apoptosis, or programmed cell death. Understanding and targeting apoptosis pathways is crucial for developing effective cancer treatments and overcoming drug resistance.

Area of Science:

  • Oncology
  • Cell Biology
  • Molecular Biology

Background:

  • Resistance to apoptosis is a hallmark of malignant cells, enabling uncontrolled proliferation and survival.
  • Defects in apoptosis signaling pathways contribute significantly to tumor cell drug resistance.
  • Targeting apoptosis is a key strategy in cancer therapy to eliminate malignant cells.

Purpose of the Study:

  • To review the role of apoptosis signaling in cancer development (tumorigenesis).
  • To examine the contribution of apoptosis defects to cancer drug resistance.
  • To discuss therapeutic strategies that modulate apoptosis pathways for cancer treatment.

Main Methods:

  • Literature review of scientific articles on apoptosis, tumorigenesis, and cancer therapy.
  • Analysis of the molecular mechanisms underlying apoptosis resistance in cancer.
  • Synthesis of current knowledge on therapeutic interventions targeting apoptosis.

Main Results:

  • Apoptosis resistance is essential for cancer cell survival and progression.
  • Dysregulation of apoptosis pathways is a common mechanism of chemoresistance.
  • Targeting apoptosis offers promising therapeutic avenues in oncology.

Conclusions:

  • Modulating apoptosis is a critical goal for overcoming cancer and drug resistance.
  • Translating knowledge of apoptosis pathways into clinical practice is a key challenge in oncology.
  • Further research into apoptosis-targeting therapies holds significant potential for improving cancer treatment outcomes.

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
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...
Apoptosis01:30

Apoptosis

Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size reduction of the tissue.
The Extrinsic Apoptotic Pathway01:17

The Extrinsic Apoptotic Pathway

The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...
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...
