Decreased Interfacial Dynamics Caused by the N501Y Mutation in the SARS-CoV-2 S1 Spike:ACE2 Complex
منشور في 2022"…Here, we dissect the mechanism underlying the increased binding affinity of the N501Y mutant for ACE2 using molecular dynamics (MD) simulations of the available ACE2-S1-RBD complex structure (6M0J) and show a prolonged and stable interfacial interaction of the N501Y mutant S1-RBD with ACE2 compared to the wild type S1-RBD. …"

Impaired histone deacetylases 5 and 6 expression mimics the effects of obesity and hypoxia on adipocyte function
منشور في 2016"…Similarly, hypoxia hampered total Hdac activity and reduced the expression of <i>Hdac5</i> and <i>Hdac6</i> in 3T3-L1 adipocytes. The decrease of both <i>Hdac5</i> and <i>Hdac6</i> by hypoxia was associated with altered expression of adipokines and of the inducible cAMP early repressor (Icer), a key repressor that is defective in human and mice obesity. …"
