Summary
This study reviews natural and synthetic compounds that induce apoptosis, or programmed cell death, to treat chronic lymphocytic leukemia (CLL). Targeting the Mcl-1/Noxa axis offers new therapeutic strategies for this incurable cancer.
Area of Science:
- Oncology
- Molecular Biology
- Pharmacology
Background:
- Chronic lymphocytic leukemia (CLL) exhibits defective apoptosis, contributing to its incurable nature.
- Apoptosis inducers, including natural products and synthetic compounds, show promise in treating CLL.
- These agents target key regulators of programmed cell death, particularly the Bcl-2 family proteins.
Purpose of the Study:
- To provide an overview of natural and synthetic apoptosis inducers for CLL.
- To elucidate the mechanisms of action of these inducers in CLL cells.
- To explore opportunities for developing novel apoptosis-based therapeutics for CLL.
Main Methods:
- Literature review of apoptosis inducers in CLL.
- Analysis of mechanisms targeting the mitochondrial apoptosis pathway.
- Focus on the Mcl-1/Noxa axis as a therapeutic target.
Main Results:
- Numerous apoptosis inducers exhibit antileukemic properties in vitro and in vivo.
- Most inducers modulate Bcl-2 family proteins, crucial for initiating apoptosis.
- The Mcl-1/Noxa axis is identified as a significant target for therapeutic intervention.
Conclusions:
- Apoptosis inducers represent a promising therapeutic avenue for CLL.
- Targeting specific apoptosis pathways, like the Mcl-1/Noxa axis, can overcome resistance.
- Further development of these agents could lead to novel treatments for chronic lymphocytic leukemia.

01:31The Intrinsic Apoptotic Pathway
6.2K
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
6.2K
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...

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...

01:17Phagocytosis of Apoptotic Cells
3.9K
Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or immature dendritic cells. Non-professional phagocytes such as epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes.

01:22Cellular Injury V: Apoptosis and Autophagy
99
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...

01:18Autophagic Cell Death
3.3K
Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.
