The role of SRT1720 and p53 in the downregulation of β-catenin induced by LPS in HUVECs. (a) Time-dependent changes in expression of β-catenin induced by 500 ng/mL LPS. (b) Pretreatment of SRT1720 prevented LPS-induced β-catenin downregulation. (c) Pretreatment of ex527 aggravated LPS-induced β-catenin downregulation. (d) SRT1720 attenuated LPS-evoked p53 319 acetylation. (e) p53 inhibition with PFT-α prevented LPS-induced EC hyperpermeability. (f) p53 inhibition with PFT-α prevented the LPS-induced decrease in β-catenin expression. versus control, # versus LPS.
