Medulloblastoma is an aggressive childhood brain tumor with poor prognosis. Recent studies indicate that dys-regulation of microRNA expression plays important roles in tumorigenesis. By comparing microRNA levels between mouse medulloblastoma and normal cerebellar tissues, we identified a set of down-regulated microRNAs including miR-31. Here, we show that(More)
Wwox is a tumor suppressor that is frequently deleted or altered in several cancer types, including breast cancer. Previous studies have shown that ectopic expression of Wwox inhibits proliferation of breast cancer cells. However, the underlying mechanism remains unclear. To better understand the molecular mechanisms of Wwox function, we investigated novel(More)
