BackgroundInformation
DNAdemethylationhasbeendemonstratedtooccurthroughatleasttwodifferentpathways:(1)activedeaminationof5-mCtoTbyanAID/APOBECenzyme,givingaG/TmismatchthatisconvertedtoG/CbythymineDNAglycosylase(TDG)andthensubsequentlybaseexcisionrepair(BER);and(2)iterativeoxidationof5-mCbyTETenzymeto5-hmCandfurtherto5-formycytosine(5-fC)and5-carboxylcytosine(5-caC).Both5-fCand5-caCcanberapidlyexcisedbyTDGtoallowsubsequentBERprocessingwhichresultsin5-fCand5-caCconvertingbacktounmodifiedcytosine.

TDGbelongstotheTDG/mugDNAglycosylasefamily.BesidesplayingacriticalroleinactiveDNAmethylation,TDGalsoremovesthyminemoietiesfromG/Tmismatchesbyhydrolyzingthecarbon-nitrogenbondbetweenthesugar-phosphatebackboneofDNAandthemismatchedthymine.IthasbeenshownthatTDGparticipatesintheregulationofembryonicandgermcelldevelopment,mediatescellulardefenseagainstgeneticandepigeneticmutations,andmediatesDNA-directedcytotoxicity.Inaddition,TDGisaproposedtumorsuppressorcandidate.Thus,themeasurementofTDGactivitywouldbeimportantasTDGmaybeinvolvedinpreventingtumOrigenesisanddeterminingcellularresponsetochemotherapythroughDNAdemethylationandBER,therebybenefitingCancerdiagnosticsandnewtarget-basedcancertherapeutics. 

ThecurrentlyusedmethodsforTDGactivitydetectioninvolveDNAcleavagefollowedbyelectrophoresis,whichcanbetimeconsumingandinconvenient,withlowthroughputandhighcost.Toaddressthisissue,EpigentekdevelopedandofferstheEpigenase™ThymineDNAGlycosylase(TDG)Activity/InhibitionAssayKit(Colorimetric).
