摘　　要： 目的观察阿帕替尼对人唾液腺样囊性癌(salivary adenoid cystic carcinoma,SACC)细胞的体内外抑制作用,并初步探讨相关机制。方法(1)应用不同浓度的阿帕替尼作用于SACC83,在不同时间点检测细胞活力;(2)构建人裸小鼠SACC83细胞皮下移植瘤模型,每天瘤内注射400μg/mL阿帕替尼0.1 mL,连续注射14 d后,安乐死动物并测量肿瘤的大小、体积和质量;(3)实时荧光定量PCR方法检测400μmol/L阿帕替尼处理4 d后的SACC83细胞中血管生成相关基因VEGFR2、HGF、EGF和Angiogenin的mRNA表达水平。结果(1)400μmol/L阿帕替尼作用于SACC83细胞4 d,能显著抑制SACC83细胞的增殖,抑制率为61.3%(P<0.01);(2)阿帕替尼能显著抑制裸小鼠SACC细胞皮下移植瘤的生长。阿帕替尼组肿瘤质量(382.33±125.29)mg比对照组减少约4倍(P<0.01),阿帕替尼组肿瘤体积(189.75±98.94)mm 3比对照组减小8倍(P<0.01);(3)400μmol/L阿帕替尼可下调SACC83细胞中血管生成相关基因VEGFR2、HGF、EGF和Angiogenin的mRNA表达水平。结论阿帕替尼可抑制人涎腺腺样囊性癌SACC83细胞的增殖,下调SACC83细胞VEGFR2、HGF、EGF和Angiogenin的mRNA表达。 Objective To assess the inhibitory effect and mechanism of apatinib on salivary adenoid cystic carcinoma in vitro and in vivo.Methods(1)We detected cell viability of salivary adenoid cystic cancer cell line SACC83 after treatment with different concentrations of apatinib at different time points;(2)The nude mice tumor model of subcutaneous transplantation of SACC83 cells was established,apatinib(0.1 mL,400μg/mL)was injected into the tumor for 14 days and tumor volume and weight were measured;(3)Quantitative PCR was used to detect the mRNA expression of angiogenesis-related genes including VEGFR2,HGF,EGF and Angiogenin in SACC83 cells after treating with 400μmol/L apatinib for 4 days.Results(1)400μmol/L apatinib inhibited the proliferation of SACC83 cells,with an inhibition rate of 61.3%(P<0.01);(2)Apatinib administration in vitro inhibited the growth of subcutaneous transplantation tumor of SACC83 cells in nude mice.The tumor weight(382.33±125.29)mg of apatinib group was about 4 times less than that of the control group(P<0.01),and the tumor volume(189.75±98.94)mm 3 of apatinib group was about 8 times smaller than that of the control group(P<0.01);(3)400μmol/L apatinib lowered the mRNA levels of VEGFR2,HGF,EGF and Angiogenin in SACC83 cells after treatment with 400μmol/L apatinib for 4 days.Conclusion Apatinib may inhibit the proliferation of SACC83 cells by down-regulating the expression of VEGFR2,HGF,EGF and Angiogenin mRNA.
