Fig. 4From: Astragalus polysaccharide restores insulin secretion impaired by lipopolysaccharides through the protein kinase B /mammalian target of rapamycin/glucose transporter 2 pathwayAPS restored GLUT2, GCK, PDX-1, and INSdownregulated by LPS. INS-1 cells were treated as indicated for 24 h. The mRNA levels of GLUT2 (A), GCK (B), PDX-1 (C), and INS (D) were determined by qRT-PCR. n = 3, *P < 0.05, **, ##P < 0.01Back to article page
