FoxO3 silencing decreases high glucose-induced apoptosis in CMECs.

<p>A: Confocal imaging of TUNEL (green fluorescent) and DAPI (blue fluorescent) staining in CMECs incubated with FoxO3a siRNA or control siRNA (Crt siRNA) for 24 h. (Scale bars: 50 µm). B: Quantification of the apoptotic CMECs was presented as the percentage of apoptotic cells. (n = 5, *p<0.05 vs. Crt siRNA plus normal condition, ^#p<0.05 vs. Crt siRNA plus high glucose).
