Anti-inflammatory and Antioxidant Properties of PLGA Nanoparticles Produced From Kombucha Extract on A2780 Human Ovarian Cancer Cell Line

Anti-cancer agents encapsulated in nanoparticles (NPs) can result in higher efficiency. Kombucha is a fermented tea beverage, and previous reports support its anti-cancer properties.

The present study aimed to evaluate the anti-cancer and anti-inflammatory properties of poly (lactic-co-glycolic acid) loaded Kombucha NPs (PLGA-K-NPs) against the A2780 human ovarian cancer cell line.

The antioxidant activity was analyzed using ferric reducing ability of plasma and 2,2’-azino- bis(3-ethylbenzothiazoline-6-sulfonic acid) assays, along with the measurement of catalase (CAT) gene expression. The gene expression of three interleukins (IL-1 β, IL-6, and IL-10) was also determined to demonstrate the anti-inflammatory properties of NPs.

The results revealed the antioxidant effects of PLGA-K-NPs on the studied cell lines by increasing Fe3+ reduction, inhibiting the free radical formation (P < 0.001), and increasing the expression of the CAT gene (P < 0.001). In addition, NPs could significantly elevate the gene expression of IL-10 (P < 0.01) as an anti-inflammatory cytokine at a 40 μg/mL concentration, while reducing the expression of IL-1β and IL-6, and inflammatory cytokines at all tested concentrations (P < 0.01).

According to the obtained results, PLGA-K-NPs have anti-inflammatory and anti-oxidant properties, therefore, they can be considered as a compound in the treatment of ovarian cancer. However, it needs to be further investigated in animal studies to clarify more d
