简介：Objective:RecentevidenceindicatesthatdysregulationofmicroRNA(miRNA)biogenesisisimplicatedincancerdevelopmentandprogression.BasedontheimportantroleofmiRNAbiogenesisgenesincarcinogenesis,wehypothesizedthatgeneticvariationsofthemiRNAbiogenesisgenesmaymodulatesusceptibilitytocervicalcancer.Methods:Weidentifiedthreesinglenucleotidepolymorphisms(SNPs)locatedinthe3’-untranslatedregions(3’-UTR)ofofmiRNAbiogenesiskeygenes(rs1057035inDICER,rs3803012inRANandrs10773771inHIWI)andgenotypedtheseSNPsinacase-controlstudyof1,486cervicalcancercasesand1,549cancer-freecontrolsinChinesewomen.Results:LogisticregressionanalysesshowedthatnosignificantassociationswereobservedbetweenthethreeSNPsandcervicalcancerrisk[rs3803012inRANAG/GGvs.AAadjustedOR=1.104,95%confidenceinterval(CI):0.859-1.419;rs1057035inDICERCT/CCvs.TTadjustedOR=0.962,95%CI:0.805-1.149;rs10773771inHIWICT/CCvs.TTadjustedOR=0.963,95%CI:0.826-1.122].Conclusions:Thefindingsdidnotsuggestthatgeneticvariantsinthe3’-UTRofRAN,DICERandHIWIofmiRNAbiogenesisgeneswereassociatedwiththeriskofcervicalcancerinthisChinesepopulation.
