FIU Electronic Theses and Dissertations
The human genome is constantly attacked by endogenous and exogenous sources of DNA damage that generates DNA base lesions and strand breaks leading to genome instability, cell death, and diseases. To combat these adverse effects, cells have evolved a robust DNA repair mechanism called “the DNA base excision repair (BER),” which efficiently removes DNA lesions maintaining genome stability. However, its underlying molecular mechanisms remain to be elucidated. In my dissertation research, I explored the molecular mechanism by which BER modulates trinucleotide repeats (TNR) by processing non-B form structures such as hairpins and R-loops through the coordination among BER enzymes and …
