Formulation of quinoa oil-alginate loaded nanoemulsion and its anticancer efficacy as a therapy for chemically induced breast cancer.

Abstract

Quinoa seeds (Chenopodium quinoa Willd.) have gained interest due to their naturally occurring phytochemicals and antioxidants. They possess potent anticancer properties against human colorectal cancer. Fatty acids in quinoa oil were studied using gas chromatography-mass spectrometry. Rats were used to test the acute oral toxicity of the nanoemulsion loaded with sodium alginate. The DPPH radical scavenging method was employed to assess the nanoemulsion's ability to scavenge free radicals. It was examined the in vivo anticancer potential of quinoa oil nanoemulsion on rats with breast cancer induced by 7, 12-dimethylbenz (a) anthracene (DMBA). DMBA-breast cancer models received daily quinoa oil nanoemulsions for 30 days. The anticancer effect of the nanoemulsion was assessed by measuring ROS, protein carbonyl, gene expression of anti-oncogenes, and histopathological analysis. Supplying quinoa oil nanoemulsion significantly reduced the increase in serum ROS and PC levels induced in breast cancer tissue. The expression levels of antioncogenes in breast cancer tissue were decreased by the quinoa oil nanoemulsion. Nanoemulsions also improved the cellular morphology of breast tumors. The study results indicate that quinoa oil nanoemulsion has anticancer activity against breast cancer, effectively modulating oxidative stress markers, anti-oncogene expressions, and tissue architecture. It can be inferred from the results that quinoa oil nanoemulsion is a chemoprotective medication that may hinder breast cancer progression in rats.
