Abstract :
Recent researches revealed that phosphoinositide 3-kinase/protein kinase B (PI3K/Akt) plays an important role in the development of drug resistance, reducing the anti-tumour activity of cytotoxic drugs, such as docetaxel (DTX). The aim of this reported work has been to evaluate DTX and the PI3K/Akt inhibitor perifosine co-loaded Fol/R7 (folate/R7) nanoparticles (NPs) for enhancing anti-cancer activity. The NPs were evaluated by size, zeta potential and morphology. Then cell viability, cellular uptake and apoptosis were performed in MCF-7 and MCF-7/Adr cells. The PI3K/Akt inhibition effect was assessed by western blotting. Compared with other experimental groups, DTX and perifosine loaded Fol/R7 NPs displayed the highest cytotoxicity, cell uptake and early apoptosis in MCF-7/Adr cells. Furthermore, the PI3K/Akt inhibition effect was enhanced by the Fol/R7 NPs compared with the free drug group. The DTX and perifosine co-loaded Fol/R7 NPs could be a potential, safe and efficient option for enhancing anti-cancer activity.
