  1. A Relational Database for the Caenorhabditis elegans Nematode By Andrea Adams Advisors: Dr. Ed Harcourt and Dr. Lorraine Olendzenski Bioinformatics is a field in which computer systems are used to process experimental data from biological experiments. Working with members of the Biology Department, I have constructed a relational database system to aid in processing the data from gene expression experiments done using a microarray or DNA chip. The Anoxia Gene Expression Group is specifically interested in genes expressed in neurons and mitochondria in the nematode C. elegans when it is raised in an environment devoid of oxygen. To identify these genes easily from among over 22,500 candidates, I mined data from the existing SAGE and Mitores databases to construct two relational databases: one detailing all of the genes expressed in neurons, and the other detailing the genes expressed in mitochondria. Once experimental data has been loaded into the database, the biologists use a web interface to access and query the databases. These queries involve selecting experimental data for genes expressed in neurons, mitochondria, or both that are either up-regulated or down-regulated around a cutoff value specified by the user.
