For example, the HnRNPR-CCNB1/CENPF axis may contribute to gastric cancer proliferation and metastasis (Chen E. B. et al., 2019), CNN1 may be a potential prognostic marker of bladder cancer according to a bioinformatics analysis (Liu Y. et al., 2019), and the combined detection of CEA with FABP4 and FABP6 may improve the diagnostic efficacy of CRC (Zhang et al., 2019). This evidence concerns the gene FABP4 and gastric cancer.
