摘要:

【目的】 珊瑚状猴头菌(Hericium coralloides(Scop.)Pers.)是一种食药用菌,重点优化其多糖(HCP)的超声提取方案,并对HCP的体外抗结直肠癌活性及机制进行探索。【方法】 利用单因素实验结合响应面法(response surface methodology,RSM)对HCP超声提取条件进行优化。通过MTT实验与Western blot分析对HCP的抗结直肠癌活性与机制进行研究。【结果】 珊瑚状猴头菌多糖超声提取的最优提取方案如下:提取功率417 W,液料比62 mL/g,提取时间52.5 min,多糖的提取率预测值为19.61%,实际提取率为(19.58± 0.05)%。HCP通过降低SW480细胞中IKK、IκBα和NF-κB的磷酸化水平,减少了促炎因子IL-6的分泌,抑制SW480细胞生长,半数抑制浓度(half maximal inhibitory concentration,IC50)为1.246 mg/mL。【结论】 珊瑚状猴头菌多糖的最佳超声辅助提取率为19.58%,HCP通过抑制NF-κB信号通路减少促炎细胞因子的分泌,进而抑制SW480细胞生长,对于结直肠癌具有潜在的治疗作用。

Abstract:

【Objective】 Hericium coralloides(Scop.)Pers. is a medicinal and edible fungus. This study focused on optimizing the ultrasonic extraction process of its polysaccharides(HCP)and exploring the in vitro anti-colorectal cancer activity and underlying mechanisms of HCP. 【Method】 Single-factor experiments combined with response surface methodology(RSM)S was used to optimize the ultrasonic extraction conditions of HCP. MTT assays and Western blot analyses were applied to investigate the anti-colorectal cancer activity and mechanisms of HCP. 【Result】 The optimal ultrasonic extraction conditions for H. coralloides polysaccharides were as follows: extraction power of 417 W, liquid-to-material ratio of 62 mL/g, and extraction time of 52.5 min. The predicted extraction yield of polysaccharides was 19.61%, with an actual yield of(19.58±0.05)%. HCP inhibited the growth of SW480 cells by reducing the phosphorylation levels of IKK, IκBα, and NF-κB, thereby decreasing the secretion of the pro-inflammatory factor IL-6. The half-maximal inhibitory concentration(IC50)was 1.246 mg/mL. 【Conclusion】 The optimal ultrasonic-assisted extraction rate of H. coralloides polysaccharides was 19.58%. HCP suppressed the secretion of pro-inflammatory cytokines by inhibiting the NF-κB signaling pathway, thus inhibiting the growth of SW480 cells. These findings suggest that HCP has potential therapeutic effects on colorectal cancer.
