B-cell-specific Moloney murine leukemia virusintegration site 1(ami—11 is a member ofpolycomb group,which participates in axial patteming,hematopoiesis, cell cycle regulation, and senescence.Recently,overexpression of Bmi-1 has been reported in various human cancers and proved to be associated with poor survival.The aim of this study was to investigate the expression of Bmi-1 protein in (UCC)and explore its associations with clinicopathological factors and prognosis.
