Insights

Cardiac apoptosis, often overlooked, significantly impacts heart function. Inhibiting caspases, key enzymes in apoptosis, improves myocardial contractility, offering a potential therapeutic strategy for heart disease.

Area of Science:

  • Cardiovascular Biology
  • Cellular Biology
  • Molecular Medicine

Context:

  • Cardiac apoptosis was historically considered a minor event in heart disease.
  • Recent findings suggest a more significant role for apoptosis in myocardial dysfunction.
  • Understanding cardiomyocyte apoptosis signaling is crucial for developing new treatments.

Purpose:

  • To review the specific involvement of caspases in myocardial dysfunction.
  • To highlight the characteristic signaling pathways of cardiomyocyte apoptosis.
  • To explore the therapeutic potential of caspase inhibition in heart disease.

Summary:

  • Low levels of dead cells in cardiac pathologies led to the misconception of apoptosis as an epiphenomenon.
  • Apoptosis prevention, particularly caspase inhibition, has demonstrated significant improvements in myocardial contractile performance.
  • This review details caspase roles in heart dysfunction and cardiomyocyte apoptosis signaling.

Impact:

  • Caspase neutralization emerges as a promising therapeutic strategy for treating heart diseases.
  • Targeting apoptosis pathways could lead to novel interventions for cardiovascular conditions.
  • This research reframes the understanding of apoptosis in cardiac pathology, opening new avenues for treatment.

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...
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...
Autophagic Cell Death01:18

Autophagic Cell Death

Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.
