Pancreatic cancer (PC) is the fourth leading cause of death in the US. Even though all the key players in PC development are known the treatment options for PC have remained the same for over 30 years. Hence, newer approaches are needed to identify other genes that may be involved in PC development. Cancer is known to be an evolutionary disease and hence we are proposing to apply the laws of phylogenetics to understand the early events in PC development at molecular level. The main focus of this project is to analyze the OMIC data using a completely new approach and identify new genes that are expressed at different stages during PC development. Using methodology described in Abu-Asab et al [2006], we built a Phylogenetic tree from the gene expression data. Using this method we identified new genes and pathways that may be involved in PC. Also we were able to divide these genes into various stages (Normal, Pan Lesions and PC) of pancreatic cancer development.
