“…Previous studies have demonstrated that increasing mRNA levels of GK, GLUT-1 and GLUT-4, while decreasing mRNA levels of G6P, can ameliorate diabetes and that regular administration of FGF-21 might increase the expression of GLUT-1 and GK while decreasing G6P gene expression in the liver [42][43][44][45][46]. The present study's real-time PCR results show that PEGylated FGF-21 can significantly increase gene expression of GLUT-1 and GK and decrease G6P expression in the liver compared with insulin glargine, which brought about glucose homoeostasis through upregulation of GLUT-4 in WAT.…”
