Summary
Genetic instability fuels cancer development and drug resistance. Targeting cancer cells with cytotoxic therapies that exploit altered apoptotic pathways offers a promising therapeutic strategy.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Genetic instability is a key driver in cancer initiation and the development of therapeutic resistance.
- Cancer cells often exhibit altered apoptotic signaling due to oncogene and tumor suppressor activity.
- Understanding these alterations is crucial for developing effective cancer treatments.
Purpose of the Study:
- To explore the role of genetic instability in cancer progression and therapy resistance.
- To investigate the potential of targeting apoptotic pathways in cancer treatment.
- To identify therapeutic windows based on altered apoptotic signaling in cancer cells.
Main Methods:
- Review of existing literature on genetic instability, cancer biology, and apoptosis.
- Analysis of oncogene and tumor suppressor roles in apoptotic pathway regulation.
- Conceptualization of therapeutic strategies targeting apoptotic differences between cancer and normal cells.
Main Results:
- Genetic instability significantly contributes to both cancer origin and acquired resistance to therapies.
- Apoptotic pathways are frequently dysregulated in cancer cells compared to normal cells.
- These dysregulations represent a potential therapeutic vulnerability.
Conclusions:
- Cytotoxic therapies may be more effective than cytostatic ones against cancers characterized by genetic instability.
- Exploiting the altered apoptotic signaling in cancer cells can lead to novel drug development.
- Targeting apoptotic pathways offers a promising strategy for overcoming cancer drug resistance.

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.
01:17The 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...
01:31The 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...
01:19Interactions Between Signaling Pathways
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

01:22Amplifying Signals via Enzymatic Cascade
When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze the...
01:07MAPK Signaling Cascades
Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...
