Objective:TheresultsofapreviousstudyshowedthatacleardysregulationwasevidentintheglobalgeneexpressionoftheBCL11A-suppressedB-lymphomacells.Inthisstudy,thebonemorphogeneticproteinreceptor,typeII(BMPR2),E1Abindingproteinp300(EP300),transforminggrowthfactor-β2(TGFβ2),andtumornecrosisfactor,andalpha-inducedprotein3(TNFAIP3)geneexpressionpatternsinB-cellmalignancieswerestudied.Methods:TherelativeexpressionlevelsofBMPR2,EP300,TGFβ2,andTNFAIP3mRNAinB-lymphomacelllines,myeloidcelllines,aswellasincellsfromhealthyvolunteers,weredeterminedbyreal-timequantitativereversetranscriptpolymerasechainreaction(qRT-PCR)withSYBRGreenDye.Glyceraldehyde-3-phosphatedehydrogenase(GAPDH)wasusedasreference.Results:TheexpressionlevelofTGFβ2mRNAinB-lymphomacelllineswassignificantlyhigherthanthoseinthecellsfromthehealthycontrol(P<0.05).However,theexpressionlevelofTNFAIP3mRNAinB-malignantcellswassignificantlylowerthanthatofthehealthycontrol(P<0.05).TheexpressionlevelsofBMPR2andEP300mRNAshowednosignificantdifferencebetweenB-malignantcelllinesandthehealthygroup(P>0.05).InB-lymphomacelllines,correlationanalysesrevealedthattheexpressionofBMPR2andTNFAIP3(r=0.882,P=0.04)hadsignificantpositiverelation.TheexpressionlevelsofBMPR2,EP300,andTNFAIP3mRNAincelllinesfrommyeloidleukemiaweresignificantlylowerthanthoseinthecellsfromthehealthycontrol(P<0.05).TheexpressionlevelsofTGFβ2mRNAshowednosignificantdifferencebetweenmyeloidleukemiacelllinesandthehealthycontrolorB-malignantcelllines(P>0.05).TheexpressionlevelsofBMPR2,EP300,andTNFAIP3mRNAinB-lymphomacellsweresignificantlyhigherthanthoseofthemyeloidleukemiacells(P<0.05).Conclusion:DifferentexpressionpatternsofBMPR2,EP300,TGFβ2,andTNFAIP3genesinB-lymphomacellsexist.更多还原
