Fig. 6. SIRT1 promotes the nuclear export and degradation of YAP under UF.

Fig. 6

a HUVECs were infected with lentivirus overexpressing SIRT1 for 72 h and the total abundance and nuclear enrichment of YAP protein in the presence of SIRT1 overexpression was detected using western blot. N-YAP represented nuclear YAP. Numbers under the blots were mean ± SD of three biologically independent experiments, and the first lane was served as relative control. b Luciferase assay showed the activity of 8 × GTIIC reporter in SIRT1-overexpressing HUVECs exposed to DF. Upper panel, western blot to confirm the SIRT1 level after overexpression. c Real-time PCR showed the expression levels of YAP downstream genes CTGF and CYR61 in SIRT1-overexpressing HUVECs. d HUVECs were treated with 10 μM sirtinol and exposed to UF. Then, western blot showed the total abundance of YAP protein under UF. e Real-time PCR showed the expression levels of YAP downstream genes CTGF and CYR61 under the treatment of 10 μM sirtinol together with UF.
