摘要 目的 :研究RTN4C裸基因直接注射抗肝癌生长及转移复发作用。方法 :将RTN4C装入逆转录病毒载体 ,扩增提取RTN4C裸基因 ,以LacZ为对照组。将不同裸基因和生理盐水与LCI D2 0裸鼠人肝癌同时皮下接种或待LCI D2 0肝癌成瘤后注射 ,观察对肿瘤成瘤和生长影响。LCI D2 0肿瘤裸鼠皮下接种后 10天 ,分别瘤内注射不同裸基因 ,观察其对肿瘤生长转移影响。LCI D2 0肿瘤肝内接种 ,接种后 2 2天行肝癌切除术 ,术中经切缘或脾内注射不同裸基因 ,观察其对术后转移复发的影响。结果 :不同裸基因与LCI D2 0肝癌同时皮下接种对照组、LacZ组、RTN 4C组 ,肿瘤直径分别为 (1 81± 0 12 )cm ,(1 6 1± 0 2 7)cm、 (0 4 3± 0 0 4 )cm。裸基因肿瘤内注射对照组、LacZ组、RTN4C组 ,瘤径 (cm)分别为 0 91± 0 0 9,0 90± 0 0 6 ,0 2 5± 0 0 4 ;肝癌切除术应用裸基因转移灶累及部位数、切缘复发瘤直径、肝内转移灶数目 ,转移灶累及肝叶数在对照组、LacZ组与RTN4C组间存在显著差异。脾内注射效果优于肝切缘组注射。结论 :RTN4C裸基因注射具有抑制LCI D2
