Abstract

Insights

Gene editing to remove Caspase-1 protected retinal cells from photochemical damage. This suggests Caspase-1 is a potential therapeutic target for preventing vision loss in retinal photochemical damage.

Area of Science:

  • Ophthalmology
  • Molecular Biology
  • Genetics

Background:

  • Retinal photochemical damage (RPD) contributes to ocular diseases.
  • Caspase-1 is a key factor in RPD development.
  • Understanding Caspase-1's role is crucial for developing treatments.

Purpose of the Study:

  • To investigate the protective effects of Caspase-1 gene-mediated pyroptosis against RPD.
  • To assess the role of Caspase-1 in cellular response to light-induced damage.
  • To explore Caspase-1 as a therapeutic target for RPD.

Main Methods:

  • Identified RPD-associated genes from GEO database.
  • Generated Caspase-1 knockout 661W cells using CRISPR-Cas9.
  • Assessed cell viability, proliferation, ROS, and cytotoxicity post-light exposure.

Main Results:

  • Confirmed successful Caspase-1 knockout.
  • Caspase-1 knockout cells showed increased viability and proliferation after light exposure.
  • Downstream pyroptosis factors were significantly reduced in knockout cells.

Conclusions:

  • CRISPR/Cas9-mediated Caspase-1 knockout enhances cellular resistance to RPD.
  • Caspase-1 inhibition offers a potential therapeutic strategy for RPD-related conditions.
  • Targeting Caspase-1 may prevent vision loss in RPD patients.

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...

Overview of Cell Death01:30

Overview of Cell Death

Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

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...
