Figure 3.

The effect of short-term glucose stimulation on PPI mRNA stability in HIT-T15 cells (A and B) and pancreatic islet cells (C and D). (A and C) Analysis of the stability of the total PPI mRNA pool. (B and D) Analysis of the stability of the preexisting PPI mRNA pool. Values of PPI mRNA were normalized to amounts of β-actin mRNA. Elevation of RNA levels in stimulated cells is shown as percentage of RNA levels of the nonstimulated control, the average value of which is given as 100%. Data are shown as mean values ± SD (n = 3).
