The role of FBXW7, a cell-cycle regulator, as a predictive marker of recurrence of gastrointestinal stromal tumors

Background Few reliable prognostic markers have been established despite elucidation of the molecular mechanisms of gastrointestinal stromal tumor (GIST) development. We evaluated F-box and WD repeat domain-containing 7 (FBXW7), a cell-cycle-regulating and tumor suppressor, in GISTs. We aimed to determine the clinical relevance of FBXW7 in GISTs and characterize the molecular mechanism of FBXW7 in a GIST cell line.
