Promising, but ultimately disappointing. The curve fitting to the mRNA data was not convincing (the shape of the data did not match the fit). Measurements (mRNA and ChIP-chip in particular) should probably have large error bars, bringing fine distinctions in timing or affinity into question. Time resolution was also questionable - the first measurement was taken at 15 minutes, but differences in activation time of 3 minutes vs. 4 minutes were treated as significant. No data was presented to support the claim on correlation between binding affinity motifs and transcriptional activation motifs, and the conclusions were presented in a confusing fashion (why claim that 20/48 data sets showed correlation, rather than breaking things out by individual motifs?).
