Insights

Selective inhibitors targeting effector caspases 3 and 7 can prevent apoptosis. This finding supports novel anti-apoptotic strategies for diseases involving programmed cell death, maintaining cell function.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Cell Biology

Background:

  • Caspases are critical proteases regulating apoptosis (programmed cell death).
  • Understanding the precise role of effector caspases in apoptosis is essential.
  • Investigating selective inhibition of caspases is key to controlling cell death.

Purpose of the Study:

  • To determine if selective inhibition of effector caspases prevents apoptosis.
  • To identify and characterize novel inhibitors of caspases 3 and 7.
  • To explore therapeutic potential of caspase inhibition in diseases.

Main Methods:

  • Development of potent, selective non-peptide inhibitors.
  • Assay development for caspase 3 and 7 activity.
  • Assessment of apoptosis inhibition and cell functionality.

Main Results:

  • Identification of potent and selective non-peptide inhibitors for caspases 3 and 7.
  • Demonstration that these inhibitors effectively block apoptosis.
  • Preservation of cellular functionality in the presence of inhibitors.

Conclusions:

  • Selective inhibition of effector caspases 3 and 7 effectively prevents apoptosis.
  • Caspase inhibitors offer a promising strategy for therapeutic intervention.
  • Novel anti-apoptotic approaches can be developed for diseases with dysregulated apoptosis.

Targeted Cancer Therapies02:57

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.
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...

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...
