FEBS Lett. 2007;581:673-80 pubmed..eNOS and Tie2 were upregulated. No effects on Ang-1 expression were detected. In conclusion, Foxo-1 and Ang-2/Tie2 are part of the molecular response to shear stress, which may regulate angiogenesis. ..

J Virol. 2010;84:11661-9 pubmed publisher..Since the sequence element has no counterpart at the other end of U(L), we concluded that our results can provide an explanation for the almost exclusive orientation of the U(L) seen in packaged VZV DNA...

J Neurochem. 2003;84:35-42 pubmed..Variations in the availability of cholesterol may promote or impair synaptic efficiency by interfering with this complex. ..
- Lenk U, Sommer T. Ubiquitin-mediated proteolysis of a short-lived regulatory protein depends on its cellular localization. J Biol Chem. 2000;275:39403-10 pubmed..These observations imply that both the cellular targeting of a substrate and the compartment-specific activity of components of the ubiquitin-proteasome system define the half-life of naturally short-lived proteins. ..
