Transcription profiling of human Soas-2 cells infected with adenoviruses expressing p53 proteins with charge-neutralizing or charge-inverting mutations in the H1 helix to investigate the role of the dimerization interface in p53 function

ABSTRACT: To investigate the role of the dimerization interface for p53 function, we introduced modest charge-neutralizing (R181→L "EL") and more severe charge-inverting (R181→E "EE" and E180→R, R181→E "RE") mutations into the H1 helix of the full-length p53 molecule. To characterize the nuclear transcriptional function of p53 mutants in an unbiased manner we employed gene expression profiling using cDNA microarrays. Saos-2 cells were infected with adenoviruses expressing the p53 proteins EE, EL, WT and RE which span the entire spectrum of apoptotic activity. Total cellular RNA was isolated 18 hours after infection when apoptosis had not yet occurred.
