PLoS ONE. 2013;8:e68341 pubmed publisher..DNA repair is a cellular defence mechanism responding to DNA damage caused in large part by oxidative stress. There is a controversy with regard to the effect of red blood cells on DNA damage and cellular response...
- Dubin Bar D, Bitan A, Bakhrat A, Kaiden Hasson R, Etzion S, Shaanan B, et al. The Drosophila IKK-related kinase (Ik2) and Spindle-F proteins are part of a complex that regulates cytoskeleton organization during oogenesis. BMC Cell Biol. 2008;9:51 pubmed publisher..Interestingly, Ik2 in this complex does not function as a typical IKK in that it does not direct SpnF for degradation following phosphorylation. ..

Perit Dial Int. 2008;28:648-54 pubmed..We found that rHuEPO provides ERK1/2-dependent protection to PMCs from PDF-induced apoptosis. The use of rHuEPO, or any of its new derivatives that do not stimulate erythropoiesis, should be considered for peritoneal preservation. ..
