| abstractText | Fabry disease is caused by deficient activity of lysosomal enzyme alpha-galactosidase A. The enzyme deficiency results in intracellular accumulation of glycosphingolipids, leading to a variety of clinical manifestations including hypertrophic cardiomyopathy and renal insufficiency. The mechanism through which glycosphingolipid accumulation causes these manifestations remains unclear. Current treatment, especially when initiated at later stage of the disease, does not produce completely satisfactory results. Elucidation of the pathogenesis of Fabry disease is therefore crucial to developing new treatments. We found increased activity of androgen receptor (AR) signaling in Fabry disease. We subsequently also found that blockade of AR signaling either through castration or AR-antagonist prevented and reversed cardiac and kidney hypertrophic phenotype in a mouse model of Fabry disease. Our findings implicate abnormal AR pathway in the pathogenesis of Fabry disease and suggest blocking AR signaling as a novel therapeutic approach. |
