The Arking Lab
The Arking Lab studies the genomics of complex human disease, with the primary goal of identifying and characterizing genetics variants that modify risk for human disease. The group has pioneered the use of genome-wide association studies (GWAS), which allow for an unbiased screen of virtually all common genetic variants in the genome. The lab is currently developing improved GWAS methodology, as well as exploring the integration of additional genome level data (RNA expression, DNA methylation, protein expression) to improve the power to identify specific genetic influences of disease.
The Arking Lab is actively involved in researching:
• autism, a childhood neuropsychiatric disorder
• cardiovascular genomics, with a focus on electrophysiology and sudden cardiac death (SCD)
• electrophysiology is the study of the flow of ions in biological tissues

Our research laboratory studies the roles mobile DNAs play in human disease. Our group was one of the first to develop a targeted method for amplifying mobile DNA insertion sites in the human genome, and we showed that these are a significant source of structural variation (Huang et al., 2010). Since that time, our group has continued to develop high throughput tools to characterize these understudied sequences in genomes and to describe the expression and genetic stability of interspersed repeats in normal and malignant tissues. We have developed a monoclonal antibody to one of the proteins encoded for by Long INterspersed Element-1 (LINE-1) and showed its aberrant expression in a wide breadth of human cancers (Rodi? et al., 2014). We have demonstrated acquired LINE-1 insertion events during the evolution of metastatic pancreatic ductal adenocarcinoma and other gastrointestinal tract tumors (Rodi? et al., 2015). We have major projects focused on studying functional consequences of inh...erited sequence variants, and exciting evidence that these predispose to cancer risk and other disease phenotypes. Our laboratory is using a combination of genome wide association study (GWAS) analyses, custom RNA-seq analyses, semi-high throughput gene expression reporter assays, and murine models to pursue this hypothesis. view more
The Halushka laboratory is interested in the overarching question of expression localization in tissues. To address this, the laboratory has set out upon several avenues of discovery in the areas of microRNA expression, proteomics and tissue gene expression. Many of these queries relate to the cardiovascular field as Dr. Halushka is a cardiovascular pathologist. Come learn about the science being done in the laboratory.
