Topoisomerase II-beta binding protein 1 (TopBP1) is a critical regulatory protein that integrates diverse signals in the DNA damage response. In response to DNA replication stress, TopBP1 participates in a series of protein interactions to collectively activate the key Ser/Thr kinase, Ataxia...
Breast cancer is the most common cancer among women in the developed world. The disease results from the combined effects of genetic, environmental, reproductive and lifestyle risk factors. Germline DNA variations identified thus far by linkage and genome-wide association studies (GWASs) account...
Identification of small molecule inhibitors of the human DNA repair enzyme polynucleotide kinase/phosphataseDownload
Human polynucleotide kinase/phosphatase (hPNKP) is a bifunctional DNA repair enzyme that phosphorylates DNA 5’-termini and dephosphorylates DNA 3’-termini. hPNKP has been shown to be involved in both single- and double-strand break repair, and cancer cells depleted of hPNKP show significant...
Developing a new drug is a complex, highly structured, and expensive task. The further a potential drug progresses in the development process, the more costly its failure becomes. Virtual screening (VS) is the initial stage of a drug discovery process. Its job is to screen large compound...
DNA is continuously under stress from the insults inflicted by both endogenous and exogenous agents. These agents include endogenous reactive oxygen species (ROS), ionizing radiation (IR) and many common chemotherapeutic drugs, which can inflict a plethora of DNA lesions including abasic sites,...
Radiation therapy targets cancer cell death by overwhelming cells with harmful DNA damage. Understanding how cells repair radiation damage and in particular how they become resistant to radiation therapy is important for effective cancer treatment. Our lab made the novel discovery that Bcl10, a...
Besides being the most popular drug in the world, caffeine is an attractive tool used in research to help us answer fascinating scientific questions, because caffeine impinges on a number of molecular pathways. In my research, I used caffeine to study DNA repair pathways and insect xenobiotic...
