ABSTRACT
Transfection of keratinocytes with plasmid DNA leads to the loss of detectable DNA-binding activity of CCAAT displacement protein but not of Yin Yang 1, as monitored by electrophoretic mobility shift assay. This phenomenon was found to be attributable to the presence of plasmid DNA in the nuclear extracts prepared from transfected cells. Treatment of these nuclear extracts with DNase I restored the ability to monitor DNA-binding activity of CDP. This report documents a new pitfall associated with transfection.

    In response to stress, p53 binds and transactivates the internal TP53 promoter, thus regulating the expression of its own isoform, Δ133p53α. Here, we report that, in addition to p53, at least four p63/p73 isoforms regulate Δ133p53 expression at transcriptional level: p63β,...
