In this study, integrin-mediated targeting and near-infrared fluorescence (NIRF) traceable polyethylene glycol-b-poly(lactic-co-glycolic acid) (PEG-PLGA)-based polymeric nanoparticles (NPs) were prepared to investigate the effects of paclitaxel (PTX) and curcumin (CUR) combination therapy on breast cancer. Cyclic (arginine-glycine-aspartic acid-phenylalanine-lysine) (cRGDfK) was selected as a ligand for breast cancer and conjugated to the end of NPs (cRGDfK-NPs). For fluorescence imaging, sulfo-cyanine 5.5 (Cy5.5) was incorporated into NPs (Cy5.5-NPs). A series of hybrid NPs consisting of NPs, cRGDfK-NPs, and Cy5.5-NPs with drugs encapsulated inside the core (Cy5.5-cRGDfK-NPs/PTX + CUR) were prepared by self-assembly. The efficacy of PTX and CUR combination and the ability of the integrin-mediated targeting of NPs were systemically investigated using a 4T1 mouse breast cancer cell line and a nude mouse xenograft model. We suggested that Cy5.5-cRGDfK-NPs/PTX + CUR has superior theranostic potential against breast carcinoma.
在这项研究中，制备了整合素介导靶向的近红外荧光（NIRF）可追踪的聚乙二醇-聚（乳酸-共-乙醇酸）（PEG-PLGA）基聚合物纳米颗粒（NPs），以研究紫杉醇（PTX）和姜黄素（CUR）联合治疗对乳腺癌的影响。环（精氨酸-甘氨酸-天冬氨酸-苯丙氨酸-赖氨酸）（cRGDfK）被选为乳腺癌的配体，并连接到 NPs 的末端（cRGDfK-NPs）。为了荧光成像，磺基花菁 5.5（Cy5.5）被掺入 NPs 中（Cy5.5-NPs）。通过自组装制备了一系列包含 NPs、cRGDfK-NPs 和内部封装药物的核（Cy5.5-cRGDfK-NPs/PTX + CUR）的杂化 NPs。使用 4T1 小鼠乳腺癌细胞系和裸鼠异种移植模型系统地研究了 PTX 和 CUR 联合的疗效以及 NPs 整合素介导靶向的能力。我们认为 Cy5.5-cRGDfK-NPs/PTX + CUR 对乳腺癌具有优越的治疗潜力。
