Overexpression of NKAP restored the proliferation ability of curcumin‐treated HUVECs. (a) Cell viability of HUVECs was increased by overexpression of NKAP. (b) Representative images of the expression levels of NF‐κB, Cyclin D1, VEGFB, MMP‐9 and NKAP in HUVECs as detected by Western blotting. Overexpression of induced the expression of all the molecules. (c) Representative images of cell cycle distribution as detected by flow cytometry. Overexpression of NKAP increased the number of cell distributed in S phase. “a,” Significantly different from NC group, P<.05. “b,” Significantly different from 1275 mimics group, P<.05. “c,” Significantly different from 1246 mimics group, P<.05
