The researchers measured serum FGF-1 levels in patients with T2DM by ELISA for the first time, and the results showed that body mass index and glycosylated hemoglobin were independent factors affecting serum FGF-1 levels, serum FGF-1 levels were significantly associated with T2DM, and FGF-1 blood concentrations were significantly increased in diabetic patients (72). This evidence concerns the gene FGF1 and type 2 diabetes mellitus.
