DNA-binding regulates site-specific ubiquitination of IRF-1.

Understanding the determinants for site-specific ubiquitination by E3 ligase components of the ubiquitin machinery is proving to be a challenge. In the present study we investigate the role of an E3 ligase docking site (Mf2 domain) in an intrinsically disordered domain of IRF-1 [IFN (interferon) regulatory factor-1], a short-lived IFNγ-regulated transcription factor, in ubiquitination of the pr...

Traceless and Site-Specific Ubiquitination of Recombinant Proteins

Protein ubiquitination is a post-translational modification that regulates almost all aspects of eukaryotic biology. Here we discover the first routes for the efficient site-specific incorporation of δ-thiol-L-lysine (7) and δ-hydroxy-L-lysine (8) into recombinant proteins, via evolution of a pyrrolysyl-tRNA synthetase/tRNA(CUA) pair. We combine the genetically directed incorporation of 7 with ...

Site – specific PEGylation of rHuEPO and evaluation of its biological activity and stability

Despite the critical role of erythropoietin (EPO) as therapeutic agent in treatment of anemia, its consumption is limited due to several disadvantages including the product short half-life, immunogenicity and susceptibility to proteolytic degradation. To overcome these drawbacks efficient methods such as site-specific PEGylation have been developed among witch N-terminal PEGylation has found mo...

N-acetylcycsteine attenuates the deleterious effects of radiation therapy on inci-sional wound healing in rats.

BACKGROUND During preoperative radiotherapy, effective doses of ionizing radiation occasionally cause wound complications after subsequent surgery. This study was designed to determine the effects of intraperitoneally or orally administered N-acetylcysteine (NAC) on anastomotic healing of irradiated rats. MATERIAL & METHODS Forty Wistar albino rats were randomized into four groups containing ...

Tanshinol Attenuates the Deleterious Effects of Oxidative Stress on Osteoblastic Differentiation via Wnt/FoxO3a Signaling

There is now increasing evidence which suggests a pivotal role for oxidative stress in the development and progression of osteoporosis. We confirm herein the protective effects of natural antioxidant Tanshinol against oxidative stress in osteoblastic differentiation and the underlying mechanism. Our results show that hydrogen peroxide (H2O2) leads to accumulation of reactive oxygen species (ROS...
