Abstract
BACKGROUND
Most of the bioactive peptides exhibit antioxidant effect and do elicit inhibitory effect on proliferation of cancer cells. This study investigates the in-vitro antioxidant and anti-cancer properties of NV14 peptide, derived from serine O-acetyltransferase (SAT) of spirulina, Arthrospira platensis.
METHODS
The anti-cancer effect of the peptide was evaluated using human adenocarcinoma epithelial cells (MCF-7), while the anti-oxidant potential, as in reduction in ROS concentration, has been established using the H2O2-exposed, Madin-Darby canine kidney (MDCK) cells. The outcome of the in vitro analyses has been evaluated by in silico molecular docking analyses.
RESULTS
The peptide, dose-dependently, reduced oxidative stress as well as cell proliferation. Besides, based on the binding scores between NV14 peptide and the important proteins associated with apoptosis and antioxidant defense, it is evident that the peptide has antioxidant and anti-cancer effect, in vitro.
CONCLUSIONS
Together, this study demonstrates that NV14 has a potent antioxidant and anti-cancer capability; however, further direction needs to be focused on clinical or pharmacodynamics aspects.
