Translesion Synthesis And Mutations: On The Mutagenic Properties Of The Two Dna Lesions, 8-Oxo-G And Pt-Gg, And The Functions Of Y-Family Dna Polymerases And Rev3l On The Bypass Of Each Of The Dna Lesions In Mammalian Cells, Lizhen Guo Apr 2015

Translesion Synthesis And Mutations: On The Mutagenic Properties Of The Two Dna Lesions, 8-Oxo-G And Pt-Gg, And The Functions Of Y-Family Dna Polymerases And Rev3l On The Bypass Of Each Of The Dna Lesions In Mammalian Cells, Lizhen Guo

Electronic Thesis and Dissertation Repository

I studied the capabilities of the two DNA lesions 8-oxo-guanine and cisplatin intrastrand crosslinked 1,2-d(GpG) or Pt-GG to cause mutations in mammalian cells. Using isogenic cell lines generated from mice with selective gene knockouts of distinct DNA polymerases as models, I deduced the biological functions of the translesion DNA polymerases Pol eta, Pol kappa, Pol iota, Rev1 and Rev3L on bypassing each of the lesions 8-oxo-G and Pt-GG. My study takes advantage of the Next Generation Sequencing (NGS) technology to determine mutagenic effects of the DNA lesions in vivo and effects of translesion DNA polymerases on bypassing the ...
