摘要：

目的研究携带BABL/c小鼠VEGFR-3(1-3Ig)基因的重组腺病毒转染淋巴管内皮祖细胞(LEPCs)后,对可溶性VEGFR-3蛋白分泌及其生物学特性的作用。方法采用巢式RT-PCR技术从BABL/c小鼠胎盘组织中扩增VEGFR-3(1-3Ig)的编码基因,并通过重组PCR技术在基因的N端加上人CD33的信号肽。将该基因片段亚克隆入腺病毒表达载体(pDC316-IRES-EGFP),重组质粒经酶切及测序验证后,与包装质粒共转染293细胞以产生重组腺病毒。将构建好的携带有小鼠VEGFR-3(1-3Ig)基因的重组腺病毒转染淋巴管内皮祖细胞,通过ELISA检测转染细胞上清液中可溶性VEGFR-3蛋白的分泌及其对VEGF-C的中和作用。结果成功构建了带有信号肽的BABL/c小鼠VEGFR-3(1-3Ig)基因的腺病毒表达质粒,并获得高滴度的携带有小鼠VEGFR-3(1-3Ig)基因的重组腺病毒,重组腺病毒转染淋巴管内皮祖细胞后,可使转染细胞分泌可溶性VEGFR-3蛋白,该蛋白具有中和VEGF-C的作用。结论成功地制备了携带BABL/c小鼠VEGFR-3(1-3Ig)基因的重组腺病毒,用该病毒转染淋巴管内皮祖细胞可使其分泌可溶性VEGFR-3,该蛋白在体外具有中和VEGF-C的作用,这为临床抑制肿瘤淋巴管新生奠定了基础。
