Foxp3 expression in pancreatic carcinoma cells as a novel mechanism of immune evasion in cancer.

abstract：:A molecular target associated with the progression of gastric cancer has not yet been uncovered. FBXW7 is a tumor suppressor gene transcriptionally controlled by p53 that plays a role in the regulation of cell cycle exit and reentry via c-Myc degradation. Few studies have addressed the clinical significance of FBXW7 e...
