苏木对肺癌干细胞荷瘤小鼠原发肿瘤CD44v6表达的影响

目的研究苏木对肺癌干细胞样细胞PG-BE1荷瘤小鼠原发瘤中CD44v6蛋白表达的影响。方法利用无血清培养法分选PG-BE1细胞中的干细胞样细胞,将干细胞样细胞亚群接种于小鼠下肢脚垫。采用药物对小鼠进行干预,第21天剥取小鼠原发瘤组织,采用Western Blot法、免疫组化法检测原发瘤组织CD44v6的表达。结果原发瘤重方面,苏木联合顺铂组较空白组、苏木组和顺铂组减少(P<0.05)。苏木加顺铂组较顺铂组、苏木组、空白组CD44V6表达较少(P<0.05)。免疫组化法检测苏木在原发瘤组织中CD44v6均有表达。结论苏木可以协同顺铂减少CD44v6蛋白的表达从而增加肺癌干细胞样细胞荷瘤小鼠模型原发肿瘤的抑瘤率。

Inhibitory effect of Sumu(Lignum Sappan) plus Fuzi(Radix Aconiti Lateralis Praeparata) on a lung carcinoma model

OBJECTIVE: To investigate the inhibitory effect of Sumu(Lignum Sappan) plus Fuzi(Radix Aconiti Lateralis Praeparata)(SF) on the growth and metastasis of Lewis lung carcinoma.METHODS: A lung carcinoma model was established by subcutaneously inoculating Lewis lung carcinoma cells into C57 BL/6 mice. The mice were randomly divided into four groups of 13 mice(control, low-dose, moderate-dose, and high-dose), and gavaged once-daily for 21 consecutive days. The rates of tumor inhibition, metastasis, and metastasis inhibition were observed. The differential expressions of s P-selectin and vascular endothelial growth factor C(VEGFC) were compared between the treatment groups and the control group.RESULTS: The tumor weights differed significantly between the treatment groups and the control group(P < 0.05). Administration of SF in the moderate-dosage and low-dose groups significantly inhibited the expression of s P-selectin and VEGFC(both P < 0.05), suggesting anti-tumor activity.CONCLUSION: SF can inhibit the growth and metastasis of Lewis lung carcinoma.
