Insights

This study identified 78 nonsynonymous single nucleotide polymorphisms (nsSNPs) in human caspases. A subset of these nsSNPs may significantly impact protein function and potentially increase cancer risk.

Area of Science:

  • Genetics
  • Molecular Biology
  • Bioinformatics

Background:

  • Cancer genetics and mutations are key research areas.
  • Caspases are crucial for apoptosis; their malfunction contributes to cancer.
  • Single nucleotide polymorphisms (SNPs), especially nonsynonymous SNPs (nsSNPs), are linked to genetic diseases.

Purpose of the Study:

  • To detect nsSNPs in human caspase data.
  • To evaluate potentially damaging nsSNPs within human caspases.
  • To analyze the functional and structural impact of these nsSNPs.

Main Methods:

  • Computational approaches were employed.
  • Identification of nsSNPs in human caspase sequences.
  • Utilized multiple SNP prediction tools for validation.

Main Results:

  • Identified seventy-eight nsSNPs in human caspases.
  • Several nsSNPs were predicted to have serious functional and structural consequences.
  • Cross-verification from various SNP prediction tools confirmed potentially damaging nsSNPs.

Conclusions:

  • The identified nsSNPs in human caspases may be associated with cancer risk.
  • Computational analysis provides insights into nsSNP impact on caspase function.
  • Further investigation is warranted to confirm the role of these nsSNPs in tumorigenesis.

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...
NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.
