Insights

Apoptotic protease activating factor-1 (Apaf-1) is crucial for programmed cell death and tumor suppression. Understanding Apaf-1 pathways may lead to novel anti-cancer drug development for improved chemoresistance.

Area of Science:

  • Cell Biology
  • Molecular Biology
  • Biochemistry

Context:

  • Apoptotic protease activating factor-1 (Apaf-1) is a key regulator of the intrinsic mitochondrial apoptosis pathway.
  • Apaf-1 facilitates the formation of the apoptosome, which activates caspase-9, initiating programmed cell death.
  • The Apaf-1 gene plays a critical role in DNA damage-induced apoptosis, impacting tumor suppression and drug resistance.

Purpose:

  • To review the structure, function, and signaling mechanisms of Apaf-1.
  • To explore the role of Apaf-1 in apoptosis and its implications in cancer.
  • To discuss the therapeutic potential of targeting Apaf-1 in tumor treatment.

Summary:

  • Apaf-1 is essential for initiating apoptosis via the intrinsic mitochondrial pathway by forming the apoptosome and activating caspase-9.
  • Dysregulation or inactivation of Apaf-1 is linked to cancer progression and chemoresistance.
  • Research into Apaf-1's mechanisms offers potential for developing new anti-cancer therapies.

Impact:

  • Elucidating Apaf-1's role provides insights into cancer biology and therapeutic resistance.
  • Findings support the development of novel anti-cancer drugs targeting the apoptosis pathway.
  • This review highlights the clinical prospects of Apaf-1-based cancer treatment strategies.

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...
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...
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.
Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
Phagocytosis of Apoptotic Cells01:17

Phagocytosis of Apoptotic Cells

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. 
Normal cells contain receptors that prevent them from being recognized by phagocytes.
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.
