 Research Summary
Precise epigenetic gene and genome regulation is critical for normal development and epigenetic dysregulation is now recognized as an underlying factor in many human disorders. Our laboratory investigates two diseases whose etiologies are based in disrupted epigenetic regulation, facioscapulohumeral muscular dystrophy (FSHD) and Rett Syndrome (RTT). We combine biochemistry, molecular, cellular, and developmental biology approaches with unique animal models generated in Xenopus, Drosophila, and C. elegans to first understand the normal function of the proteins involved in these diseases and later how their disrupted regulation leads to disease pathophysiology. Along the way we are identifying new biological pathways involved in RTT progression and new biomarkers disrupted in FSHD patient skeletal muscle.
