Figure Lengend Snippet: YAP was identified as the substrate for UFMylation (A and B) Immunoblotting and quantification of the level of the indicated protein in HUVECs of the proliferation of PDL at 10 and 30; immunoblotting and quantification of levels of the indicated protein in aortic endothelial cells from 2 (young) or 24 (aged) months old mice. n = 3. (C) HEK293T cells were co-transfected with UFMylation components (UBA5, UFC1, UFL1, and DDRGK1) or wild-type (UFM1WT) or active UFM1 (UFM1ΔC2) or defective UFM1 (UFM1ΔC3) and FLAG-tagged YAP for detection exogenous YAP UFMylation. (D) Isolation of aortic endothelial cells from 8-week-old C57BL/6J mice for detection endogenous YAP UFMylation. (E) Immunofluorescence staining of YAP (green), UFM1 (red), and DAPI (blue) in HUVECs of the proliferation of PDL at 10 and 30, and serum stimulation as control, scale bars: 20 μm. (F) Isolated the nucleus and cytoplasmic proteins from young and senescent HUVECs, immunoblotting and quantification of levels YAP. n = 4. (G) UFMylation detection of YAP was identified using a PLA with UFM1 and YAP antibodies. n = 6, p values correspond to unpaired two-tailed Student’s t test.
