Summary
This study reviews apoptosis pathways and their role in cancer cell survival. It highlights novel anticancer drugs that reactivate apoptosis and methods for visualizing therapy-induced cell death.
Area of Science:
- Molecular Biology
- Cell Biology
- Cancer Biology
Context:
- Apoptosis, or programmed cell death, is crucial for development and tissue homeostasis.
- Dysregulation of apoptosis contributes to cancer cell survival and resistance to therapy.
- Understanding apoptosis mechanisms is key to developing effective cancer treatments.
Purpose:
- To present current knowledge on the molecular mechanisms of apoptosis, including extrinsic and intrinsic pathways.
- To discuss the role of apoptotic pathway dysregulation in cancer chemoresistance and radioresistance.
- To survey novel therapeutic strategies targeting apoptosis and methods for visualizing therapy-induced cell death.
Summary:
- The extrinsic death receptor and intrinsic mitochondrial pathways of apoptosis are detailed.
- Cancer cells evade apoptosis, leading to treatment resistance.
- New anticancer drugs aim to selectively induce apoptosis in malignant cells, with some in clinical trials.
- Non-invasive in vivo imaging techniques for monitoring therapy-induced apoptosis are reviewed.
Impact:
- Provides a comprehensive overview of apoptosis in cancer biology.
- Identifies promising therapeutic targets and strategies for cancer treatment.
- Highlights advancements in visualizing treatment response in vivo.
- Informs future research on apoptosis-modulating cancer therapies.

02:57Targeted 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.

01:31The 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...
01:17The 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...
01:30Apoptosis
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.
01:22Cellular Injury V: Apoptosis and Autophagy
Cells respond to damage and stress through highly coordinated processes that decide whether they survive or undergo controlled self-destruction. Two major pathways involved in this regulation are apoptosis, a type of programmed cell death, and autophagy, a survival mechanism that helps cells adapt to adverse conditions.ApoptosisApoptosis removes aged or injured cells to maintain tissue balance. During this process, the cell shrinks, chromatin condenses and fragments, and membrane-bound...
