UFM1 and gastric cancer: Concurrently, we also detected the expression level of UFM1 in several gastric cancer cell lines and found that the expression level of UFM1 was negatively correlated with the differentiation degree of gastric cancer cell lines (N87 is a highly differentiated gastric cancer cell, AGS and MGC-803 are moderately differentiated, HGC-27 is poorly differentiated) (Fig. 1g), suggesting that UFM1 may be closely related to the progression of gastric cancer.
