1、论著·中国医药导报2014年9月第11卷第25期PI一103对人黑色素瘤A375细胞迁移和侵袭能力的影响及其机制研究陆茂叶俊儒彭科宋黎成都医学院第一附属医院皮肤科,四川成都610500【摘要】目的观察PI一103在体外对人黑色素瘤A375细胞迁移和侵袭能力的影响,并探讨可能的作用机制。方法应用MTT法检测不同浓度PI一103对A375细胞增殖的影响,Transwell小室实验检测0.1、0.2Ixmol/LPI一103对A375细胞迁移能力和侵袭能力的影响,WesternBlot法测定细胞基质金属蛋白酶(MMP)一2、MMP一9的表达。
2、结果0.1、0.2Ixmol/LPI一103对A375细胞增殖的抑制作用不明显(P>0.05);在浓度高于0.4txmol/L时,PI一103能够明显抑制A375细胞的增殖(P3、<0.05)。0.1、0.2Ixmol/LPI一103作用后,A375细胞MMP一2、MMP一9蛋白表达明显低于对照组,差异有统计学意义(P<0.05)。结论PI一103可通过下调MMP一2、MMP一9的表达抑制A375细胞迁移和侵袭,为其应用于抗恶性黑素瘤转移治疗提供了实验依据。【关键词】PI-103;黑色素瘤;迁移;侵袭[中图分类号】R739.5【文献标识码]A【文章编号】1673-7210(2014)09(a)-0014-04EffectsofPI-103onmigratoryandinvasiveabilitiesofhuman4、melanomaA375cellsanditsmechanismLUMaoYEJunruPENGKeSONGLiDepartmentofDermatology,theFirstAfiliatedHospitalofChengduMedicalCollege,SichuanProvince,Chengdu610500,China【Abstract]ObjectiveToinvestigatetheeffectsofPI-103onthemigratoryandinvasiveabilitiesofhumanmelanomaA375cell5、sinvitroanditsmechanism.MethodsTheeffectsofPI-103withdifferentconcentrationontheproliferationofA375cellsweredetectedbyMTrassay.TheeffectsofPI一103at0.1.0.2Izmol/LconcentrationonthemigratoryandinvasiveabilitiesofA375cellsweredetectedbytranswellchamberassay.Theexpressionsof6、MMP-2andMMP-9inA375cellsweredeterminedbyWesternBlot.ResultsTheinhibitioneffectsontheproliferationofA375cellstreat—edwithPI-103at0.1,0.2~mol/Lconcentrationwerenotsignificant>0.05).TheproliferationofA375cellstreatedwithPI一103attheconcentrationhigherthan0.4txmol/Lwassignifi7、cantlyinhibitedfP<0.05).Thenumbersoftrans—membranecellsinthemigrationandinvasionexperimenttreatedwithPI-103at0.1Ixmol/Lconcentrationwere(91.73~13.80),(63.67~8.54)respectively,whichweresignificantlydecreasedcomparedwithcontrolgroup(尸<0.05).Thenumbersoftransmembranecellsin8、themigrationandinvasionexperimenttreatedwithPI-103at0.2txmol/Lcon—centrationwere(64.07~9.22),(34.80~7.8
