Enhancement by interleukin-1 (IL-1) of plasminogen activator inhibitor (PA-I) activity in cultured human endothelial cells.

Abstract:

:Cultured human endothelial cells produce increased levels of PA-I when stimulated with IL-1. The stimulatory effect was elicited by both alpha (pI 5) and beta (pI 7) IL-1 molecules. The effect was both dose and time-dependent, plateau reached after 8 h. The PA-I measured in cell extracts was SDS-resistant with an apparent m.w. of 53 Kd and inhibited both tissue-type plasminogen activator (t-PA) and urokinase (UK). No change in t-PA antigen level was detected with any of the IL-1 preparations tested.

  • Mdm2 is required for HDAC3 monoubiquitination and stability.

    abstract::HDAC3, one of the class I histone deacetylase modulates epigenetic landscape through histone modification. HDAC3 also interacts with non-histone proteins including p53 for deacetylation. Moreover, HDAC3 serves as a transcriptional repressor, interacting with NCor1/SMRT complex. Although HDAC3 plays a critical role for...
