Insights

Anticancer drugs induce cell death via two main pathways: death receptor signaling or mitochondrial cytochrome c release. Understanding these apoptosis pathways is crucial for improving chemotherapy effectiveness and overcoming drug resistance.

Area of Science:

  • Cellular biology
  • Molecular biology
  • Pharmacology

Background:

  • Apoptosis, or programmed cell death, is a critical process in multicellular organisms.
  • Two primary intrinsic cell-death pathways have been identified: the death receptor pathway and the mitochondrial pathway.
  • Anticancer drug efficacy is linked to their ability to induce apoptosis in cancer cells.

Purpose of the Study:

  • To review the two main pathways of apoptosis.
  • To discuss experimental methods for differentiating these pathways in response to chemotherapy.
  • To summarize the role of these pathways in chemotherapy-induced apoptosis and drug resistance.

Main Methods:

  • Literature review of studies on apoptosis pathways and chemotherapy.
  • Analysis of experimental approaches for pathway determination.
  • Synthesis of current understanding of chemotherapy-induced apoptosis.

Main Results:

  • Chemotherapeutic agents can trigger apoptosis through either the death receptor pathway (e.g., via Fas ligand) or the mitochondrial pathway (cytochrome c release).
  • Experimental methods exist to distinguish which pathway is activated by specific drugs.
  • The interplay between these pathways influences cancer cell survival and drug response.

Conclusions:

  • Distinguishing between the two major apoptosis pathways is essential for understanding chemotherapy mechanisms.
  • Knowledge of these pathways can inform strategies to enhance anticancer drug efficacy.
  • Understanding these pathways is key to addressing mechanisms of resistance to chemotherapeutic agents.

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...
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...
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...
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...

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy.  SP binds and activates these...

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.
