Does differential regulation by SV40 T-antigen binding at site I define two distinct classes of nucleosome-free promoter?
The results indicate that there are two distinct classes of nucleosome-free promoter region in SV40 chromatin and that T-antigen binding to site I is specifically involved in the regulation of only the class that contains a large nucleosome-free region.
CPB affects the cellular immune system; however, this effect seems to be a physiological reaction, independent of the applied CPB circuit system.
