Insights

Mitochondrial protein release triggers apoptosis, but the exact mechanisms remain debated. This review explores how cancer cells exploit these pathways and potential therapies targeting mitochondrial outer membrane integrity.

Area of Science:

  • Cell biology
  • Molecular biology
  • Cancer research

Background:

  • Mitochondrial outer membrane permeabilization (MOMP) is crucial for apoptosis.
  • The release of intermembrane space proteins initiates caspase activation and cell death.
  • Mechanisms of MOMP and apoptogenic protein release are under intense investigation.

Purpose of the Study:

  • To review proposed mechanisms of apoptogenic protein release from mitochondria.
  • To discuss how cancer cells evade or manipulate these apoptotic pathways.
  • To explore therapeutic strategies targeting mitochondrial integrity in cancer.

Main Methods:

  • Literature review and synthesis of current research on mitochondrial apoptosis.
  • Analysis of cancer cell adaptations to apoptotic signaling.
  • Discussion of emerging therapeutic approaches targeting MOMP.

Main Results:

  • Several models exist for mitochondrial protein release, including pore formation and direct membrane rupture.
  • Cancer cells frequently exhibit dysregulated apoptotic pathways, contributing to treatment resistance.
  • Targeting mitochondrial integrity presents a promising avenue for novel cancer therapies.

Conclusions:

  • Understanding the nuances of mitochondrial protein release is key to deciphering apoptosis.
  • Exploiting cancer's reliance on or evasion of mitochondrial apoptosis offers therapeutic opportunities.
  • Modulating outer mitochondrial membrane integrity holds potential for effective cancer treatment.

The Intrinsic Apoptotic Pathway01:31

The 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...
Apoptosis01:30

Apoptosis

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.
Cellular Injury V: Apoptosis and Autophagy01:22

Cellular 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...
Caspases01:24

Caspases

Caspase, a family of cysteine proteases, serve as effectors in apoptosis. The ced3 gene in C.elegans was first identified to be involved in apoptosis. This gene encodes the ced-3 caspase that is similar to the interleukin-1-beta converting enzyme or ICE in mammals. In addition to apoptosis, caspases also function in the inflammatory response. Inflammatory caspases are essential in activating pro-inflammatory cytokines that recruit immune cells and block the replication of pathogens inside cells.
The Extrinsic Apoptotic Pathway01:17

The 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...
Mitochondrial Membranes01:45

Mitochondrial Membranes

A single mitochondrion is a bean-shaped organelle enclosed by a double-membrane system. The outer membrane of mitochondria is smooth and contains many porins - the integral membrane transporters. Porins enable free diffusion of ions and small uncharged molecules through the outer mitochondrial membrane but limit the transport of molecules larger than 5000 Daltons. Further, the outer mitochondrial membrane forms a unique structure called membrane contact sites with other subcellular organelles,...
