Insights

This review details how caspases, key regulators of programmed cell death (PCD), interact with apoptotic mediators and autophagy genes in cancer. It highlights PCD-modulating agents targeting caspases for future cancer drug discovery.

Area of Science:

  • Molecular Biology
  • Cellular Biology
  • Oncology

Background:

  • Programmed cell death (PCD) is a vital, genetically controlled process implicated in numerous diseases, especially cancer.
  • The caspase family is central to regulating PCD pathways.

Purpose of the Study:

  • To review the complex interactions between caspases and apoptotic mediators in cancer initiation and progression.
  • To explore the cross-talk between caspases and autophagy-related genes (Atgs) in cancer.
  • To present agents targeting caspases for potential cancer drug discovery.

Main Methods:

  • Literature review focusing on caspase family roles in cancer.
  • Analysis of interactions with apoptotic mediators: tumor necrosis factor receptors, Bcl-2 family, cytochrome c, Apaf-1, and IAPs.
  • Investigation of caspase cross-talk with autophagy-related genes (Atgs).

Main Results:

  • Caspases are intricately linked with key apoptotic mediators in cancer development.
  • Emerging evidence shows cross-talk between caspases and Atgs in the context of cancer.
  • Several PCD-modulating agents targeting specific caspases (e.g., caspase-3, -8, -9) and their substrates (PARP-1, Beclin-1) have been identified.

Conclusions:

  • Understanding caspase-mediated PCD pathways is crucial for cancer research.
  • Targeting caspases and their associated pathways offers promising avenues for novel cancer therapeutics.
  • Further research into caspase-autophagy interactions may yield new drug targets.

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 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...

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...

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.
