Abstract:BACKGROUND: Constitutive activation of STAT3 is one of the major oncogenic pathways involved in the development of various types of malignancies including结直肠癌(CRC);因此成为有前途的治疗靶标。 sp长期以来,ICA Prunellae一直被用作许多中药配方中的重要组成部分,可在临床上治疗CRC。以前,我们发现Spica Prunelae通过线粒体介导的凋亡抑制CRC细胞的生长。此外,我们在体内和体外证明了其抗血管生成活性。 To further elucidate the precise mechanism of the potential tumoricidal activity of Spica Prunellae, using a CRC mouse xenograft model, in this study we evaluated its therapeutic efficacy against CRC and investigated the underlying molecular mechanisms.
METHODS: CRC mouse xenograft model was generated by皮下注射人类结肠癌HT-29细胞中的裸鼠。每周5天,每天5天,每天5天,将动物内部用6 g/kg的Spica Prunellae(Eesp)乙醇提取物(EESP)给予动物。每两天测量体重和肿瘤生长。确定体内肿瘤生长通过测量肿瘤的体积和重量。通过MTT分析检查了HT-29细胞活力。通过免疫组织化学染色(IHS)评估了来自CRC异种移植小鼠肿瘤的细胞凋亡和增殖,用于TUNEL和PCNA,并通过使用IHS进行内皮细胞特异性标记CD31检查了肿瘤内微血管密度(MVD)。通过使用IHS确定其磷酸化水平来评估STAT3的激活。分别通过RT-PCR和IHS测量Bcl-2,Bax,Cyclin D1,VEGF-A和VEGFR2的mRNA和蛋白质表达。
CONCLUSIONS: Spica Prunellae possesses a broad range of anti-cancer activities due to its ability to affect STAT3 pathway, suggesting that Spica Prunellae could be a novel potent治疗CRC的治疗剂
