Research Overview

The major focus of our laboratory is to study the muscular dystrophies, a series of progressive disorders of striated muscle that lead to the breakdown of muscle integrity. More recently, our research efforts have expanded to other complex genetic diseases including autism and interstitial cystitis. Muscular Dystrophies Since our discovery of the Duchenne-Becker muscular dystrophy gene dystrophin, we have taken two approaches to studying these diseases. The first is to unravel the normal function of the dystrophin-associated protein complex and determine how alteration of genes encoding members of this complex causes the disease. The second is to develop different lines of therapy for patients with muscular dystrophy. These efforts include stem-cell-based therapy and drug-discovery strategies to develop pharmaceutical-based approaches. We are identifying potential drug targets by characterizing genes and microRNAs that are upregulated or downregulated in the disease, and through drug screening efforts in zebrafish deficient in the dystrophin gene. The muscles of dystrophin-deficient zebrafish embryos appear patchy under polarized light (d), characteristic of muscle tearing. Interstitial Cystitis Interstitial cystitis (IC) is a complex genetic disorder affecting nearly 1 in 2,000 people in the United States. We have identified six families in which IC is segregating, and have found five different genetic loci that are significantly or suggestively linked to the disease. We are now sequencing the genes in these regions to find the causative mutations in these families. Identification of these genes should highlight potential disease pathways and might reveal insights into therapy. For more information, click here. Autism Autism is a developmental disorder that most likely involves genes expressed in the brain and probably has both genetic and environmental causes. Because many genes expressed in the central nervous system are also expressed in whole blood, we reasoned that we might be able to find signatures of gene expression that would allow us to categorize patients with autism and possibly identify causative genes. We can now predict whether a gene expression profile is derived from a blood sample taken from an autistic child or from a control. We are expanding these studies to many more patients and controls, in the hopes of developing a diagnostic test for autism. For more information, click here.
