Inhibition of CYFIP2 promotes gastric cancer cell proliferation and chemoresistance to 5-fluorouracil through activation of the Akt signaling pathway.

Gastric cancer is a common gastrointestinal malignancy that accounts for a notable proportion of cancer-associated mortalities worldwide. Cytoplasmic fragile X mental retardation 1-interacting protein 2 (CYFIP2) is a novel p53-mediated pro-apoptotic protein whose expression is decreased in gastric cancer. However, whether decreased expression of CYFIP2 contributes to gastric carcinogenesis remains unclear. In order to mimic
