摘    要:目的观察三七总皂苷(PNS)对B16黑色素瘤生长及转移的作用,及其对B16黑色素瘤表达缝隙连接蛋白Connexin32的影响。方法实验采用B16黑色素瘤自发性肺转移模型,来观察PNS对B16黑色素瘤生长及转移的影响。免疫组织化学检测Connexin32在黑色素瘤原发灶的表达情况。结果(1)PNS对黑色素瘤生长有较好的抑制作用,其中PNS高剂量组抑瘤率可达50.85%。(2)与模型组相比PNS中、高剂量组能有效抑制黑色素瘤的肺转移,转移灶数量与对照组相比有明显减少。(3)免疫组织化学检测,发现PNS各用药组均能增强黑色素瘤原发灶细胞膜上Connexin32的表达。结论PNS能够抑制B16黑色素瘤的生长和转移,并能有效增强肿瘤细胞膜上Connexin32的表达。

关 键 词:三七总皂苷  黑色素瘤  缝隙连接蛋白

Abstract:Objective To investigate the effect of PNS on malignant melanoma and the expression of connexin32 in melanoma. Methods The spontaneous and experimental lung metastasis models of B16 melanoma were used to investigate the inhibitory effect of PNS on tumor growth and metastasis. The expression of connexin in melanoma were detected by immunohistoehemistry. Results (1) PNS can obviously inhibit the growth of B16 melanoma. The inhibition rate of the 480mg/kg PNS group was 50. 85%. (2) PNS can obviously inhibit the lung metastasis of B16 melanoma. The number of tumor colonies in lung of the 240 mg/kg PNS group and 480 mg/kg PNS group were lower than that in the negative control group. ( 3 ) The expression of connexin32 in melanoma was detected by immunohistochemistry:PNS could up-regulate the expression of connexin32 in membrane of melanoma. Conclusion PNS can inhibit malignant melanoma growth and metastasis and could also up-regulate the expression of connexin32 in membrane of melanoma.
Keywords:Panax notoginseng saponins  Malignant melanoma  Connexin
