Non-small cell lung cancer (NSCLC), which accounts for 85% of lung cancer cases, calls for better therapy. Yi-Fei-San-Jie-pill (YFSJ), a well-applicated traditional Chinese medicine formula, was reported to be effective in the treatment of NSCLC. However, its anti-tumor mechanism still needs to be fully elucidated. Herein, a reliable preclinical orthotopic but not subcutaneous model of NSCLC in mice was established to evaluate the anti-cancer properties and further validate the mechanisms of YFSJ. A bioinformatic analysis was executed to identify the potential targets and key pathways of YFSJ on NSCLC. In detail, the anti-tumor effect of YFSJ and the autophagy inhibitor 3-MA was evaluated according to the tumor fluorescence value and comparison of different groups' survival times. As a result, YFSJ markedly decreased tumor size and prolonged survival time in contrast with those in the orthotopic model group ( < 0.05), and it also significantly regulated the protein expression levels of apoptosis- and autophagy-related proteins. In conclusion, this study provides convincing evidence that YFSJ could inhibit the growth of tumors and prolong the survival time of tumor-bearing mice based on the NSCLC orthotopic model, and its anti-tumor effect was closely associated with the promotion of apoptosis and interference of autophagy coupled with regulation of immune infiltration.
非小细胞肺癌(NSCLC)占肺癌病例的85%,需要更好的治疗方法。益肺散结丸(YFSJ)是一种应用广泛的中药方剂,据报道对NSCLC治疗有效。然而,其抗肿瘤机制仍需充分阐明。在此,建立了一种可靠的小鼠NSCLC原位而非皮下临床前模型,以评估YFSJ的抗癌特性并进一步验证其作用机制。进行了生物信息学分析,以确定YFSJ对NSCLC的潜在靶点和关键途径。具体而言,根据肿瘤荧光值和不同组生存时间的比较,评估了YFSJ和自噬抑制剂3-MA的抗肿瘤作用。结果,与原位模型组相比,YFSJ显著减小了肿瘤大小并延长了生存时间(<0.05),并且还显著调节了凋亡和自噬相关蛋白的表达水平。总之,本研究提供了令人信服的证据,表明基于NSCLC原位模型,YFSJ可以抑制肿瘤生长并延长荷瘤小鼠的生存时间,其抗肿瘤作用与促进凋亡、干扰自噬以及调节免疫浸润密切相关。
