Fig. 4: SET8 interacted with FOXO1.

a Several proteins that interact with SET8 are shown in Fig. 3a (https://string-db.org). b Interactions between SET8 and FOXO1 in HUVECs were verified by Co-IP. c Colocalization of SET8 and FOXO1 in HUVECs was determined by confocal microscopy. d Results of the western blot analysis of FOXO1 in HUVECs cultured under normal or high-glucose conditions. e Results from the qPCR analysis of FOXO1 in HUVECs cultured under normal or high-glucose conditions. *P < 0.05, compared with the control group, n = 5/group.
