Abstract

Background: Pro-inflammatory cytokines play critical roles in cancer pathobiology and have been considered potential targets for cancer management and therapy. Understanding the impact of cancer therapeutics such as 5-fluorouracil (5-FU) on their expression might shed light on development of novel combinational therapies. This study aimed to encapsulate 5-FU into PLGA and evaluate their effects on the expression of pro-inflammatory genes IL-9, IL-17-A, IL-23, and IFN-y; in the HT-29 cells.

Methods: PLGA-5-FU NPs were constructed and characterized by Dynamic Light Scattering (DLS) and Atomic Force Microscopy (AFM). The cytotoxicity was evaluated by MTT test and, the IC50 was identified. HT-29 cells were treated with different concentrations of the PLGA-5-FU NPs for 48 hours and, gene expression levels were analyzed by qRT-PCR.

Results: DLS and AFM analysis revealed that the prepared PLGA-5-FU NPs were negatively charged spherical-shaped particles with a mean size of 215.9 ± 43.3 nm. PLGA-5-FU NPs impacted the viability of HT-29 cells in a dose- and time-dependent manner. The qRT-PCR results revealed a dose-dependent decrease in the expression of IL-9, IL-17A, IL-23 and IFN-y; genes, and their expressions were significantly different in both 10 and 20 µg/mL treated groups compared to the control. However, although the treatment of HT-29 cells with 20 µg/mL free 5-FU resulted in decreased expression of the studied genes, the differences were not statistically significant compared to the control group.

Conclusion: PLGA-5-FU NPs significantly suppressed expression of the IL-9, IL-17A, IL-23 and IFN-y; genes, and the encapsulation of 5-FU into PLGA improved considerably impact of the 5-FU on the HT-29 cells.

5-Fluorouracil-Loaded PLGA 可降低 HT-29 结肠癌细胞系中促炎基因 IL-9、IL-17A、IL-23 和 IFN- y 的表达。
背景:促炎细胞因子在癌症病理生物学中起着至关重要的作用,被认为是癌症管理和治疗的潜在靶点。了解癌症治疗药物(如 5-氟尿嘧啶(5-FU))对其表达的影响可能有助于开发新型组合疗法。本研究旨在将 5-FU 封装到 PLGA 中,并评估其对 HT-29 细胞中促炎基因 IL-9、IL-17-A、IL-23 和 IFN-y 表达的影响:方法:构建了 PLGA-5-FU NPs,并通过动态光散射(DLS)和原子力显微镜(AFM)对其进行了表征。细胞毒性通过 MTT 试验进行评估,并确定了 IC50。用不同浓度的 PLGA-5-FU NPs 处理 HT-29 细胞 48 小时,并通过 qRT-PCR 分析基因表达水平:DLS和AFM分析表明,制备的PLGA-5-FU NPs为带负电荷的球形颗粒,平均大小为215.9 ± 43.3 nm。PLGA-5-FU NPs对HT-29细胞活力的影响呈剂量和时间依赖性。qRT-PCR结果显示,IL-9、IL-17A、IL-23和IFN-y基因的表达量呈剂量依赖性下降,与对照组相比,10和20 µg/mL处理组的表达量均有显著差异。然而,虽然用 20 µg/mL 游离 5-FU 处理 HT-29 细胞会导致所研究基因的表达量减少,但与对照组相比,差异无统计学意义:结论:PLGA-5-FU NPs能显著抑制IL-9、IL-17A、IL-23和IFN-y基因的表达。
