WebMar 13, 2012 · Arbitrary fold change (FC) cut-offs of >2 and significance p-values of <0.02 lead data collection to look only at genes which vary wildly amongst other genes. Therefore, questions arise as to whether the biology or the statistical cutoff are more important within the interpretation. In this paper, we reanalyzed a zebrafish (D. rerio) microarray ...

You can't calculate a p-value on the fold-change values, you need to use the concentrations in triplicate thus giving a measure of the variance for the t-test to use. t-test assumes your data are normally distributed, if they aren't you're going to get spurious p-values. If you aren't sure a non-parametric test like Wilcoxon is better. rich and reserve
