Abstract
Colon cancer is one of the leading causes of mortality and morbidity worldwide. Nisin, a polycyclic antibacterial peptide and food preservative has shown potential to combat cancer. However, it is susceptible to proteolytic cleavage in the gut. The current study investigates the protective and cytotoxic effects of nisin loaded sodium alginate gum arabic nanoparticles (Nis/ALG-GA NPs) in Caco2 cells. The physicochemical properties, loading efficiency and release kinetics were studied. Cytotoxicity (MTT assay), apoptotic effect (Ethidium bromide and acridine orange staining) and internalisation (FITC tagging) were evaluated. Gene expression of apoptotic markers and IL-10 were analysed by qPCR. The Nis/ALG-GA NPs were spherical, small with a smooth outer surface and mean size of 193 ± 4 nm. The loading efficacy was 88 ± 2 % exhibiting slow sustained release of the peptide under different gut pH conditions. The IC50 value obtained was 500 μg for 48 h and 80 μg for 72 h of incubation. The Nis/ALG-GA NPs were internalised into Caco2 cells and induced apoptosis with an increased expression of bax gene and converse decrease of bcl-2 gene. Anti-inflammatory gene IL10 was upregulated upon treatment with NPs. Thus, the Nis/ALG-GA NPs may be promising oral drug delivery systems against colon cancers.
