FGB and urinary bladder carcinoma: Analyzing the proteome of urine samples from 231 humans, which consisted of healthy individuals and individuals with benign pulmonary disease, lung cancer, cervical cancer, colorectal cancer, or bladder cancer, Zhang et al. [45] could identify a panel of five biomarkers: FTL (ferritin light chain), MAPK1P1L (mitogen-activated protein kinase 1 interacting protein like), FGB (fibrinogen beta chain), RAB33B (RAB33B, member RAS oncogene family), and RAB15 (RAB15, member RAS oncogene family).
