摘要: 探讨IGF-2及IGF-1R蛋白质在子宫蓄脓的表达及与子宫蓄脓发病的相关性。采用免疫组织化学PV法与Western blotting检测5例正常子宫内膜(对照组)、19例子宫蓄脓(试验组)子宫内膜组织中IGF-2及IGF-1R的表达情况。结果表明,免疫组化与Western blotting检测结果一致,IGF-2和IGF-1R在蓄脓子宫组中的表达量极显著高于正常子宫(P<0.01)。对子宫蓄脓组中IGF-1R与IGF-2进行相关性分析,免疫组化结果表明IGF-1R与IGF-2之间低度相关(=0.423),Western blotting结果显示IGF-1R与IGF-2之间高度相关(=0.927)。结果提示,IGF-2阳性表达上调及IGF-1R的异常高表达,在子宫蓄脓的发生和发展过程中可能具有重要作用。

Abstract: To investigate the expression of IGF-2 and IGF-1R protein in endometria of canine pyometra and analyze the possible correlation with the incidence of canine pyometra.Immunohistochemistry PV method and Western blotting were used to measure the IGF-2 and IGF-1R expression characteristic of 5 normal endometria and 19 endometria of canine pyometra.The results showed that the IGF-2 level of endometria from pyometra group was extremely significant higher than that of control group by immunohistochemistry and Western blotting (P<0.01).The positive expression rate of IGF-1R in endometria of canine pyometra compared with that in the normal endometria was extremely significant higher by immunohistochemistry and Western blotting (P<0.01).The correlation analysis of IGF-2 and IGF-1R in canine pyometra showed that the result of immunohistochemistry was low correlation (=0.423), the result of Western blotting was high correlation (=0.927).The data suggested that increased expression of IGF-2 and IGF-1R played an important role in occurrence of canine pyometra.

Key words: IGF-2; IGF-1R; canine pyometra; immunohistochemistry; Western blotting
