Description
Summary:The aim of this study was to synthesize chitosan nanoparticles (Cs NPs) for resveratrol (RSV) delivery and assess their effectiveness in inducing autophagy in MDA-MB 231 cells. In this experimental study, Pure and RSV-loaded Cs NPs (RSV. Cs NPs) were prepared via the ionic gelation method, and their physicochemical properties were characterized using standard techniques, and RSV release was measured . MDA-MB 231 cells were incubated with RSV, Cs NPs, and RSV. Cs NPs and Half-maximal inhibitory concentration (IC50) values were calculated following the MTT test. Cell viability was assessed by lactate dehydrogenase (LDH) assay, and autophagy was evaluated using the real-time polymerase chain reaction (PCR). NP formation was confirmed with the analysis of FTIR spectra. Pure and RSV. Cs NPs had 36.7 and 94.07 nm sizes with 18.3 and 27 mV zeta potentials, respectively. Above 60% of RSV entrapped within NPs was released in an initial burst manner followed by a gradual release till 72 hours. Cs and RSV. Cs NPs restrained cell proliferation at lower concentrations. RSV. Cs NPs showed the highest anticancer effect and stimulated autophagy, indicated by increased Beclin-1 ATG5, ATG7, LC3A, and P62 expression. RSV. Cs NPs show promising effects in inhibiting invasive breast cancer (BC) cells by inducing autophagy.
