This study identifies the promising potential of a novel and safer nanocombination of bovine milk lactoperoxidase (LPO) and lactoferrin (LF) in targeting breast cancer in vitro and in a rat model, showing improved apoptosis pathway, immune response, inflammation reduction, and restoration of oxidative stress.
This study identifies promising potential of a novel and safer nanocombination of bovine milk lactoperoxidase (LPO) and lactoferrin (LF) to target breast cancer in vitro and in adult female albino rat model. Favorable selective anticancer effects of the prepared nanocombination were observed, in a dose-dependent manner, against both MCF-7 and MDA cell lines, sparing normal HFB-4 cells. The administration of LPO + LFNPs markedly improved the induced-breast cancer disorders, prolonged survival and reduced the values of serum TNF-alpha, IL1 beta, CD4(+), ALAT, ASAT, urea, creatinine, cholesterol and triglycerides with remarkable elevation in mammary SOD and GPx activity and GSH level. Moreover, the histopathological findings showed that LPO + LFNPs succeeded in prevention of mammary gland tumorigenesis. Superior efficacy of LPO + LFNPs was observed against pro-inflammatory cytokines through their anti-inflammatory and immunomodulatory properties. The treatment of LPO + LFNPs more significantly modulated the apoptosis and enhanced the expression of cell cycle regulator genes, which demonstrates a successful tumor therapy in vitro and in vivo. Therefore, this study provided evidence that the chemo-preventive feature of LPO + LFNPs may offer a novel alternative therapy for the treatment of breast cancer through enhances apoptosis pathway, improvement of immune response, reduction of inflammation and restoration of the impaired oxidative stress.
