Figure 1. Diabetes induces upregulation of miR-139-5p expression in endothelial cells. (A) MiR-139-5p expression in endothelial colony-forming cells (ECFCs) isolated and cultured from peripheral blood (PB) of diabetic patients and healthy adults was detected by real-time PCR. (N=4) *P < .05 (B) MiR-139-5p expression in human umbilical vein endothelial cells (HUVECs) after 7 days of high glucose or high osmotic culture was detected by real-time PCR. (N=3) *P < .05 versus day 1 (C) MiR-139-5p expression in ECFCs from health PB after 7 days of high glucose or high osmotic culture was detected by real-time PCR. (N=3) *P < .05 versus day 1 (D) MiR-139-5p expression in endothelial cells derived from the thoracic aorta of normal and diabetic rats was detected by real-time PCR. (N=6) *P < .05 versus normal rats. (E) MiR-139-5p expression in endothelial cells derived from the thoracic aorta of normal and diabetic nude mouse was detected by real-time PCR. (N=6) *P < .05 versus normal nude mouse. (F) The expression of miR-139-5p in different clone cells. (N=3) *P < .05 versus high proliferation potential ECFCs.
