O le faʻaleagaina o faʻamaʻi i faʻavae DNA e masani ona iʻu ai i le faʻavaeina o purines faʻamaʻi, aemaise lava 7,8-dihydro-8-oxoguanine (8-oxoG) ma le 7,8-dihydro-8-oxoadenine (8-oxoA), o le muamua o se lelei- iloa mutagenic manu'a.Talu ai ona o le 8-oxoG e faigofie lava ona faʻamaʻi faʻamaʻi faʻamaʻi faʻatusatusa i faʻavae masani, o le faʻaofiina o se faʻavae i le taimi o le DNA synthesis faʻafeagai ma se oxidized fomu o le 8-oxoG na suʻesuʻeina i vitro.O se faʻataʻitaʻiga faʻapipiʻi o loʻo i ai se faʻamaʻi 8-oxoG e tasi na togafitia muamua i vailaʻau faʻamaʻi e tasi-eletonika poʻo lalo ifo o tulaga okesene singlet ona faʻapipiʻiina lea i le faʻaopoopoga muamua na faʻapipiʻiina e Klenow fragment exo- (Kf exo-), calf thymus DNA polymerase alpha (pol alpha). ) po'o le tagata DNA polymerase beta (pol beta).E ogatasi ma lipoti talu ai, dAMP ma dCMP o loʻo faʻapipiʻiina faʻafeagai ma le 8-oxoG faʻatasi ai ma polymerases DNA uma e tolu.O le mea e malie ai, o le fa'ama'iina o le 8-oxoG na maua e fa'aosoina ai le dAMP ma le dGMP fa'aofi fa'afeagai ma le manu'a e Kf exo- fa'atasi ai ma le fa'alavelave le tumau o le fa'aopoopoga muamua o lo'o tupu i le nofoaga o le fa'avae ua suia.E le gata i lea, o le manu'a e fausia ai se poloka i le taimi o le fa'asologa o DNA e ala i le pol alpha ma le pol beta.O fa'ata'ita'iga i le 8-oxoA-modified template oligonucleotide e fa'aalia ai o le 8-oxoA ma le oxidized fomu o le 8-oxoA fa'aofi sa'o o le dTMP e Kf exo-.Ole su'esu'ega ole tele ole spectrometric ole 8-oxoG o lo'o iai oligonucleotides a'o le'i mae'a fa'ama'iina ma le IrCl62-e tutusa ma le fa'ama'iina o le nofoaga 8-oxoG, ma fa'atupuina ai se vaega o le guanidinohydantoin e avea ma oloa tele.Leai se fa'amaoniga mo le fa'atūina o nofoaga fa'apa'u na maua.O nei fa'ai'uga ua fa'aalia ai o se fa'ama'i fa'ama'iina o le 8-oxoG, masalo o le guanidinohydantoin, e ono fa'atonuina le fa'aseseina ma le tu'u sese o dNTP i le taimi o le fa'asologa o DNA.Afai o sea faiga na tupu i totonu o le vivo, o le a fai ma sui o se mea mutagenic lesion e tau atu i le G-->T ma le G-->C transversions.Ae ui i lea, o le foliga faʻamaʻi faʻamaʻi tutusa o le 8-oxoA o loʻo faʻaalia muamua le faʻaofiina saʻo o le T i le taimi o le DNA faʻatasi ma Kf exo-.
