My long-term goal is to become an independent molecular epidemiologist with in-depth training in genetics and advanced statistical methods in order to be able to analyze high throughput gene variant data to explore gene-gene and gene-environment interactions in cancer susceptibility. My career development plan include didatic courses/seminars, meetings with mentors in the areas of human genetics, cancer biology and advanced statistical methods. My research proposal will focus on genetic susceptibility of bladder cancer (BC). I propose to capitalize on availability of epidemiologic and genetic marker data from an on-going case-control study, """"""""Markers of Genetic Susceptibility to Bladder Cancer""""""""(R01 CA74880,PI:Xifeng. Wu). The parent study currently include over 2,500,mostly Caucasian, BC cases and controls, matched on sex, age and ethnicity. My goal is to identify novel loci that confer bladder cancer susceptibility using state-of-the-art genotyping technology and novel statistical and bioinformatics tools.
The Specific Aims are: 1) To enhance my knowledge and skills in genetics and statistics to identify novel genetic loci as susceptibility markers of BC by extending the original45 potential functional SNPs to include additional 2112 tagging SNPs in genes in the DNA repair, cell cycle control and apoptotic pathways in 800 Caucasian cases and 800 Caucasian controls using the Illumina Golden Gate Assay;2) To assess haplotypes and diplotypes as markers of susceptibility;3) To use bioinformatics tools to assess functional significance of SNPs in the DNA repair, cell cycle control and apoptotic pathways and to correlate genotype data of DNA repair and cell cycle control with functional data derived from phenotypic assays. The secondary aim is to apply hierarchical models to refine risk assessment and to apply novel machine-learning tools to explore any gene-environment and gene-gene interactions influencing BC risk. My project complements the parent grant in that it: 1) adds tagging SNPs to potential functional SNPs addressed in the parent grant;2) adds haplotype analyses;3) proposes novel statistical and bioinformatics approaches.

Public Health Relevance

Bladder cancer is a tobacco-related cancer which is the fourth most common cancer in men in U.S. The fact that only a fraction of smokers develop bladder cancer indicating genetic susceptibility to the disease. This study will identify novel genetic markers may be useful as biomarkers to identify high-risk populations that could then be targeted for intervention programs.
