The Regulation Impact of Naringenin-loaded Chitosan Nanoparticles on Succinate Dehydrogenase Activity in Cancer Cells

Oxidative phosphorylation dysregulation (OXPHOS) has been demonstrated to be essential for the development of cancer. Therefore, it may be argued that chaperone and deacetylase activities modulate OXPHOS activity. For instance, a complicated network of interactions connects a cell’s bioenergetic features and neoplastic potential through the imbalance of sirtuin 3 (SIRT3) and succinate dehydrogenase (SDH) enzymatic activity in mitochondria. The studies outlined in this review indicate that targeting SDH regulators is a promising novel therapeutic strategy for this extremely resistant disease. Additionally, a viable therapeutic strategy may involve triggering the cell death mechanism in cancer cells by blocking mitochondrial metabolism with a natural substance. A naturally occurring flavonoid called naringenin (NAR) has been extensively investigated for its pharmacological properties, which include anti-tumor actions. However, due to its low bioavailability in this situation, nanoencapsulation is designed to improve NAR anticancer efficacy. NAR can be encapsulated by chitosan nanoparticles-TPP conjugates, thereby improving NAR cellular absorption and cytotoxicity against cancer cells. Consequently, we proposed naringenin nanoparticles as a novel therapeutic target for SDH regulators in cancer.
