represents one of the principal hallmarks of several cells.
Antimicrobial peptides have been shown to exhibit selective
anticancer activities. In this study, the secreted
metabolome of HeLa cells under action of the antimicrobial
peptide Crotamine from the venom of the South American
rattlesnake Crotalus durissus terrificus was evaluated.
Crotamine has been shown to be selective for highly
proliferating cells and is able to extend the in vivo
lifespan. The present study using a cell line of cervical
cancer, HeLa cells, provide insights into how Crotamine acts
in cell metabolism. NMR spectroscopy was used to identify
and quantify relative metabolite levels, which are
associated with Crotamine uptake. Statistical analysis
reveals that Crotamine dramatically affects metabolites
related to glycolysis, metabolism and biosynthesis of amino
acids and pyruvate metabolism. The developed machine
learning model is found to be robust by ROC curve analysis,
suggesting that the metabolic state of HeLa cells treated
with Crotamine is different from the control samples. To
account for metabolite levels, it is suggested that
Crotamine would have to act on glycolysis, which, in turn,
affects several other metabolic pathways, such as,
glutathione metabolism, TCA cycle and pyruvate metabolism.
The observed metabolic changes shed light into the mode of
Crotamine function.},
