摘要 目的探讨蛋白激酶C(proteinkinaseC,PKC)亚型与KBV200肿瘤细胞多药耐药(multidrugresistance,MDR)的关系。方法(1)用Westernblotting法检测PKC亚型在耐药株KBV200及敏感株KB的表达及亚细胞分布;(2)流式细胞仪检测PKC亚型的荧光强度并对数据进行统计分析。结果(1)PKCα亚型的表达在KBV200中选择性升高,而PKCβ、ε无显著变化,PKCγ、ζ则未测出表达;(2)流式细胞仪检测发现KBV200细胞的PKCα的荧光强度较KB细胞显著升高,PKCβ、ε则无显著差别。结论PKC与KBV200MDR细胞株的MDR表型关系密切。在PKC亚型中,PKCα可能在KBV200细胞的MDR表型中起重要作用。 Objective To investigatetheassociationof proteinkinaseC(PKC)isoformsandmultidrugresistance(MDR)mechanisminKBV200cells.Methods Westernblottingwas utilizedto examinetheexpressionandsubcellulardistribution of PKCisoformsweremeasuredin KBV200cellswithMDRanddrug-sensitiveKB cells,andthefluorescence intensityof PKCisoformswasdetectedby flowcytometry(FCM).Results KBV200cellspossessedhigherPKCactivities,withincreased percentageof membranefraction.As comparedwithparentalKB cells,theexpressionof PKCαwassignificantlyincreasedin KBV200cells,whilePKCβandεexpressionsremainedunchanged,andPKCγandζfailedto be detected.Fluorescence intensityof PKCαinKBV200cellswasincreased.Conclusion PKCmightcontributeto MDRphenotypeinKBV200cells,andof theisoformsso fardetected,PKCαmightplayan importantroleinMDRphenotype.
