This article has been retracted by the publisher. An investigation at the University of Maryland, Baltimore determined that contrast and brightness were enhanced to selectively conceal LDH and Lamin B bands in Fig. 4. This drastically reduced the apparent presence of Lamin B in the cytosol fraction and of LDH in the nuclear fraction, thereby artificially increasing the difference in the proteins compared to that in the other fraction examined.
