摘要:

目的:探讨美洲大蠊提取物C-3对荷S180肉瘤小鼠抑瘤作用及机制。方法:将荷S180肉瘤小鼠随机分为模型组、阳性对照(CTX)组、C-3高、中、低剂量组,另设正常对照组,每组10只小鼠,观察给药后各组小鼠肿瘤组织的病理改变,计算抑瘤率;ELISA试剂盒检测血清中血管内皮生长因子(VEGF)和端粒酶(TE)水平;免疫组织化学法检测肿瘤组织中p53B细胞淋巴瘤-2Bcl-2)、含半胱氨酸的天冬氨酸蛋白水解酶-3Caspase-3)、微血管密度(MVD)和环氧合酶-2COX-2)蛋白的表达。结果:CTX组、C-3高、中、低剂量组小鼠抑瘤率分别为85.71%55.71%44.28%34.28%C-3高、中剂量组小鼠肿瘤组织坏死区域明显。与模型组相比,C-3高剂量组小鼠血清中TE活力降低(P<0.05),C-3高、中剂量组小鼠肿瘤组织中p53Bcl-2MVDCOX-2表达显著降低(P<0.01),Caspase-3表达显著增加(P<0.01)。结论:C-3能显著抑制S180肉瘤的生长,其机制可能与降低TE活力,减少肿瘤组织中p53Bcl-2MVDCOX-2表达,增加Caspase-3表达等途径相关。

Abstract:

ObjectiveTo investigate the anti-tumor effect and mechanism of C-3 extractive from Periplaneta americana on S180 sarcoma-bearing mice. MethodsS180 sarcoma-bearing mice were randomly divided into model grouppositive control CTXgrouphigh-dosemedium-dose and low-dose C-3 groupsand a normal control groupwith 10 mice in each group. The pathological changes of tumor tissue in each group were observed after administrationand the tumor inhibition rate was calculated. ELISA kits were used to test the levels of vascular endothelial growth factorVEGFand telomeraseTEin serum. The expression of p53B-cell lymphoma 2Bcl-2), cysteinyl asparate specific protease-3Caspase-3), microvessel density MVDand cyclooxygenase-2COX-2protein in tumor tissue were detected by immunohistochemistry. ResultsThe tumor inhibition rates of CTX grouphigh-dosemedium-doseand low-dose C-3 groups were 85.71%55.71%44.28%34.28%respectively. The necrotic area of tumor tissue was obvious in high-dose and medium-dose C-3 groups. Compared with the model groupthe TE activity was decreased in high-dose C-3 groupP<0.05), and the expression of p53Bcl-2MVD and COX-2 in tumor tissues of high-dose and medium-dose C-3 groups were significantly decreasedP<0.01), while the Caspase-3 expression was significantly increasedP<0.01. ConclusionC-3 can significantly inhibit the growth of S180 sarcomaand its mechanism may be related to the reduction of TE activitythe decrease of p53Bcl-2MVDCOX-2 expressionand the increase of Caspase-3 expression in tumor tissue.
