Summary
Snake venom proteins from Naja kaouthia were analyzed for anticancer properties. Peptides identified showed potent activity against breast cancer cells, highlighting venom as a source for new anticancer drugs.
Area of Science:
- Biochemistry
- Pharmacology
- Toxicology
Background:
- Anticancer peptides are crucial in developing novel anticancer drugs.
- Bioactive peptides can be obtained from free peptides or protein hydrolysis.
- Naja kaouthia venom, rich in proteins, is a potential source for anticancer peptides due to its toxicity.
Purpose of the Study:
- To characterize Naja kaouthia venom proteins.
- To identify anticancer peptides from Naja kaouthia snake venom.
Main Methods:
- Proteome analysis using trypsin hydrolysis and high-resolution mass spectrometry (HRMS).
- Preparative tryptic hydrolysis, reverse-phased fractionation, and anti-breast cancer activity testing.
- Molecular docking analysis to assess peptide interactions and binding affinity.
Main Results:
- Proteomic analysis identified 20 enzymatic and non-enzymatic proteins in N. kaouthia venom.
- A 25% methanol peptide fraction exhibited significant anticancer activity against MCF-7 breast cancer cells with a selectivity index of 12.87.
- Eight peptides were identified as potential anticancer compounds, with WWSDHR and IWDTIEK showing strong binding affinities (-9.3 kcal/mol and -8.4 kcal/mol, respectively).
Conclusions:
- Naja kaouthia snake venom is a potent source of novel anticancer agents.
- Identified peptides demonstrate significant potential for development into new anticancer drugs.

A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...

4.0K
Rab proteins constitute the largest family of monomeric GTPases, of which 70 members are present in humans. Rab proteins and their effectors regulate consecutive stages of vesicle transport such as vesicle transport, docking, and fusion to the correct recipient membrane.
Rab proteins switch between a cytosolic, GDP-bound inactive state and a membrane-anchored, GTP-bound active state. By themselves, Rabs show slow rates of GDP/GTP exchange and GTP hydrolysis. Thus, Rab proteins are considered...

7.5K
In organisms, proteins are the most abundant macromolecules. They act as the building blocks of life and play various crucial roles in the body. Proteins can be broadly classified into two distinct subtypes based on their shape and solubilities: globular proteins and fibrous proteins.
Globular proteins serve many important physiological functions, such as acting as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be soluble in the aqueous...

01:21Matrix Proteoglycans and Glycoproteins
4.0K
Proteoglycans are extensively glycosylated proteins, commonly found in the extracellular matrix, interwoven with collagen fibers. Hyaline cartilage, the most common type of cartilage in the body, consists of short and dispersed collagen fibers associated with large amounts of proteoglycans. These proteoglycans have long negative charges that attract cations, which in turn attract water molecules. This influx of ions and water molecules swells up the proteoglycan like a water-soaked gel that can...

01:05Proteoglycans
4.0K
Glycans, a class of complex heterogeneous molecules, can be covalently attached to proteins to form glycosylated proteins that regulate various physiological and pathological processes. Glycosylated proteins or glycoproteins comprise N-linked and O-linked oligosaccharides. O-glycosylation is the most common type of protein glycosylation. Here, glycans attach to the oxygen atom of the hydroxyl groups of Serine or Threonine residues. O-linked glycosylation occurs later in protein processing,...
