Expanding roles of BCL-2 proteins in apoptosis execution and beyond

View Original View Raw

Summary

This article reviews current understanding of the molecular mechanism of mitochondrial outer membrane permeabilization (MOMP), which is a key regulator of apoptosis. It focuses on the roles of BCL-2 proteins in apoptosis and beyond, and discusses potential implications for healthy tissues and disease. The authors also discuss the development and clinical use of drugs targeting BCL-2 proteins, as well as potential strategies to enhance efficacy or develop novel drugs to treat cancer patients.

Q&As

What are the proteins of the BCL-2 family and how do they regulate apoptosis?
The proteins of the BCL-2 family are known as key regulators of apoptosis, with interactions between family members determining permeabilisation of the mitochondrial outer membrane (MOM) and subsequent cell death.

What is the exact mechanism of the apoptotic pore responsible for MOM permeabilisation (MOMP)?
The exact mechanism through which they form the apoptotic pore responsible for MOMP, the structure and specific components of this pore, and what roles BCL-2 proteins play outside of directly regulating MOMP are incompletely understood.

What are the implications of the newly discovered roles of BCL-2 proteins in apoptosis and beyond?
The implications of the newly discovered roles of BCL-2 proteins in apoptosis and beyond may have implications in both healthy tissues and disease.

What are the benefits of drug development targeting BCL-2 proteins?
The benefits of drug development targeting BCL-2 proteins include enhancing the efficacy of these drugs, or developing novel drugs targeting BCL-2 proteins to treat cancer patients who have developed resistance or who suffer other disease types.

What are the sources of grants and funding for this research?
The sources of grants and funding for this research include the CRC1218/Deutsche Forschungsgemeinschaft.

AI Discussion

Me: It discusses the expanding roles of BCL-2 proteins in apoptosis and other processes. It talks about how these proteins are important targets for drug development to treat cancer patients, and discusses the molecular mechanisms of MOMP and other roles of BCL-2 proteins in apoptosis and beyond.

Friend: That is really interesting. What implications does this have?

Me: Well, the implications are that understanding the roles of BCL-2 proteins in apoptosis and other processes can help us develop more effective drugs to treat cancer, and possibly other diseases as well. It could also help us better understand the molecular mechanisms of MOMP, which could lead to more effective treatments. Additionally, understanding the roles of BCL-2 proteins could help us better understand the role of apoptosis in healthy tissues, which could lead to better treatments for diseases related to cell death.

Technical terms

Apoptosis: A type of programmed cell death that occurs in multicellular organisms.
Apoptotic pore: A protein complex that forms in the mitochondrial outer membrane during apoptosis, allowing for the release of cytochrome c and other apoptotic factors.
BAX: A pro-apoptotic protein that is part of the BCL-2 family.
BCL-2: A family of proteins that regulate apoptosis.
MOMP: Mitochondrial outer membrane permeabilisation, a process in which the mitochondrial outer membrane is made permeable to allow for the release of cytochrome c and other apoptotic factors.
