Herein, the authors synthesised chitosan nanoparticles (Cs NPs) as a resveratrol (RSV) carrier and evaluated their efficacy in stimulating apoptosis in MDA-MB 231 cells. Blank (Cs NPs) and RSV- Cs NPs (RSV-Cs NPs) were synthesised via ionic gelation and characterised by using fourier-transform infrared spectroscopy (FTIR), Scanning electron microscope, dynamic light scattering/Zeta potential and RSV release. MDA-MB 231 cells were treated with RSV, Cs NPs and RSV-Cs NPs (24, 48, and 72 h), followed by the 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide assay. Cell toxicity was evaluated using lactate dehydrogenase assay, and real-time polymerase chain reaction was performed to explore apoptosis induction. FTIR spectra confirmed the NPs via the formation of cross-linking bonds. Cs and RSV-Cs NPs sizes were about 75 and 198 nm with 14 and 24 mV zeta potentials. The RSV entrapment efficiency was 52.34 ± 0.16%, with an early rapid release followed by a sustained manner. Cs and RSV-Cs NPs inhibited cell proliferation at lower concentrations and IC50 values. RSV-Cs NPs had the most cytotoxic effect and stimulated intrinsic apoptotic pathway, indicated by increased Bcl-2-associated x (BAX), BAX/Bcl-2 ratio, P53 expressions, reduced Bcl-2 and upregulated caspases 3, 8 and 9. RSV-Cs NPs have a great potential to suppress invasive breast cancer cell proliferation by targeting mitochondrial metabolism and inducing the intrinsic apoptotic pathway.

壳聚糖/白藜芦醇聚合物纳米复合物对三阴性乳腺癌的抗癌作用;体外评估。

在此,作者合成了壳聚糖纳米颗粒 (Cs NPs) 作为白藜芦醇 (RSV) 载体,并评估了它们在刺激 MDA-MB 231 细胞凋亡方面的功效。空白 (Cs NPs) 和 RSV-Cs NPs (RSV-Cs NPs) 通过离子凝胶合成,并使用傅里叶变换红外光谱 (FTIR)、扫描电子显微镜、动态光散射/Zeta 电位和 RSV 释放进行表征。MDA-MB 231 细胞用 RSV、Cs NPs 和 RSV-Cs NPs(24、48 和 72 小时)处理,然后用 3-[4,5-二甲基噻唑-2-基]-2,5-二苯基四唑溴化物处理化验。使用乳酸脱氢酶测定法评估细胞毒性,并进行实时聚合酶链反应以探索细胞凋亡诱导。FTIR 光谱通过交联键的形成证实了 NP。Cs 和 RSV-Cs NP 尺寸约为 75 和 198 nm,zeta 电位分别为 14 和 24 mV。RSV 包封效率为 52.34 ± 0.16%,早期快速释放,随后持续释放。Cs 和 RSV-Cs NPs 在较低浓度和 IC50 值下抑制细胞增殖。RSV-Cs NPs 具有最大的细胞毒性作用并刺激内在凋亡途径,表现为 Bcl-2 相关 x (BAX)、BAX/Bcl-2 比率、P53 表达增加、Bcl-2 减少和半胱天冬酶 3、8 和 9 上调. RSV-Cs NPs 通过靶向线粒体代谢和诱导内在凋亡途径,具有抑制浸润性乳腺癌细胞增殖的巨大潜力。Cs 和 RSV-Cs NPs 在较低浓度和 IC50 值下抑制细胞增殖。RSV-Cs NPs 具有最大的细胞毒性作用并刺激内在凋亡途径,表现为 Bcl-2 相关 x (BAX)、BAX/Bcl-2 比率、P53 表达增加、Bcl-2 减少和半胱天冬酶 3、8 和 9 上调.
