... late steps of the process. For example, early in the NER process, RPA assists TFIIH in the opening of the DNA helix around the damage site [36]. Further- more, in the presence of the XPA minimal ... sites. Taken together, these findings suggest that the struc- tural properties of DNA-damaged substrates, whether intrinsic or the result of protein binding, function in the recruitment of the XPC–hHR23B ... Binding of XPG induces the release of XPC–hHR23B, whereas XPF–ERCC1 triggers exci- sion of the damaged DNA and the release of XPA and TFIIH. Subsequently, the newly formed gap in the DNA is filled by...

... increases the rate of transcription initiation of the PS1 gene in SK-N-SH cells To determine whether the increase in the level of PS1 mRNA results from the activation of the transcription of the gene ... in the presence of TPA. Thus the increase in the level of PS1 mRNA observed by Northern blotting of total cellular RNA results from an increase in the rate of initiation of transcription of PS1. PS1 ... Hence the identification of the mecha- nisms controlling the expression of the PS1 gene should relate directly to understanding further the development and differentiation pathways and the pathogenesis...

The total number of basal and suprabasal epithelial ... Negative controls consisted of omission of the primary or the secondary antibody or primary incubation in the presence of non-immunized rabbit serum instead of the primary antibody. Cell quantification ... OLP would require an increased immunolocalization of hMSH2. Therefore, the reduced expression of hMSH2 protein could make the epithelium of OLP more susceptible to DNA mutation, making it prone...

They are the best decisions ... decisions in which the magni- tude of the risk of being wrong is understood. The quality of decisions can therefore be judged by the degree to which uncertainties (risks) are considered in the decision ... then related to the four steps of the decision making process and finally to the three types of error (risk) that occur in each of the four steps. The paper concludes with an example of how methodical...
