Abstract:
Apoptosis is a physiological process vital for embryologic development and the maintenance of homeostasis in multicellular organisms, but it is also involved in a wide range of pathological processes, including cancer. In mammalian cells, apoptosis has been divided into two major pathways: the extrinsic pathway, activated by proapoptotic receptor signals at the cellular surface, and the intrinsic pathway, which involves the disruption of mitochondrial membrane integrity. Although many of the proteins vital for apoptosis have been identified, the molecular pathways of cellular death still remain to be elucidated. This review provides references concerning the apoptotic molecules, their interactions, the mechanisms involved in apoptosis resistance, and also the modulation of apoptosis for the treatment of cancer.
Insights
Apoptosis, a programmed cell death process, is crucial for development and homeostasis but also implicated in cancer. Understanding its pathways and resistance mechanisms is key for cancer treatment strategies.
Area of Science:
- Cell Biology
- Molecular Biology
- Biochemistry
Background:
- Apoptosis is a fundamental physiological process essential for multicellular organism development and homeostasis.
- Dysregulation of apoptosis is implicated in various pathological conditions, notably cancer.
- Two primary mammalian apoptosis pathways exist: the extrinsic (receptor-mediated) and intrinsic (mitochondrial) pathways.
Purpose of the Study:
- To review the molecular mechanisms and protein interactions governing apoptosis.
- To explore the pathways contributing to apoptosis resistance.
- To discuss the therapeutic modulation of apoptosis for cancer treatment.
Main Methods:
- Literature review of scientific references on apoptosis.
- Analysis of molecular pathways and protein interactions.
- Examination of apoptosis resistance mechanisms.
Main Results:
- Identification of key apoptotic molecules and their interactions.
- Elucidation of mechanisms underlying resistance to programmed cell death.
- Overview of strategies for modulating apoptosis in cancer therapy.
Conclusions:
- While many apoptotic proteins are known, the complete molecular pathways of cellular death require further investigation.
- Understanding apoptosis and its resistance is critical for developing effective cancer therapies.
- Targeting apoptosis pathways offers a promising avenue for novel cancer treatments.

Interactions Between Signaling Pathways
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...
