摘要
目的探讨Kaposi肉瘤相关疱疹病毒(kaposi’s sarcoma associated herpesvirus,KSHV)感染对v-yes-1Yamaguchi肉瘤病毒相关同源癌基因(v-yes-1 Yamaguchi sarcoma viral related oncogene homolog,LYN)表达的影响,及其在卡波氏肉瘤(kaposi’s sarcoma,KS)发病机制中的作用。方法采用酶灌注法原代培养脐静脉内皮细胞(human umbilical vein endothelial cells,HUVECs),运用免疫细胞化学检测CD34和CD31以验证HUVECs。从BCBL-1中提取KSHV病毒感染HUVECs,显微镜下观察细胞形态并拍照,PCR扩增KS330233证实感染成功。采用Western blot检测LYN表达及p-PI3K和p-AKT水平。结果HUVECs中CD 31胞膜阳性和CD 34胞浆阳性,说明酶灌注法取得的细胞为HUVECs。KSHV感染HUVECs后细胞变为长梭形,LYN表达增高,同时p-PI3K和p-AKT水平也增高。结论 KSHV感染HUVECs促进LYN表达,且可能通过促进p-PI3K和p-AKT水平增高而活化PI3K/AKT信号通路。
