<i>Ccn3</i> is a transcriptional target of FoxO1 in β-cells.

<p>A) <i>Ccn3</i> expression by quantitative real-time qPCR in INS832/13 cells transduced with either Ad-β-Gal or Ad-CN-FoxO1 and cultured for 24 h. Results are means +/– SEM of 4 separate experiments. B) <i>Ccn3 </i>mRNA levels in INS832/13 cells treated with or without 10% serum and LY294002 (50 µM) for 4 h. Results represent means +/– SEM of 3 separate experiments. C) <i>Ccn3</i> expression in isolated islets from WT and transgenic mice with CAFoxO1 overexpression in their β-cells (called “305 mice”) (n = 5 for each). *, p<0.05.
