摘要 Objective:Toclone,sequenceandexpresstheprimateβ-chemokineRANTESgenes,hRANTESfromH.sapiensandmRANTESfromM.Mulatta,inordertoexplorethepossibilityofAIDSgenetherapy.Methods:hRANTESandmRANTESwereamplifiedbyreversetranscription-polymerasechainreaction(RT-PCR)fromRNAsextractedfromphytoagglutinin(PHA)-activatedperipheralbloodlymphocytes,hRANTESwascloned,sequencedandexpressedinvitro,andmRANTESwasdirectlysequencedforhomologycomparison.Results:Anexpected276bpfragmentwasobtainedinbothamplifications,andsequencedatademonstratedarelativelyhighhomologyamongdifferentcopiesofhRANTES(97%),andhRANTESwasupto95.6%homologoustomRANTES.WhencomparedwithRANTESfromothermammals,hRANTESgaverisetoahomologyrangingfrom77%to86%.TheclonedhRANTESwasexpressedinvitroandapositivesignalofRANTESwasdetectedbydotblotting.Conclusion:Thefull-lengthofhRANTESsequencewassubmittedtoGenBankandhadbeenreleased.OurmRANTESsequenceisfirstreportedandnotyetappearedinGenBank.ThesuccessfulcloningandexpressionofhRANTESwillprovideabasisforAIDSgenetherapyinthefuture.
