Comparison and correlation between results obtained through qPCR and microarrray, in terms of fold change and p-value (or adjusted p-value).

Correlation coefficients of logarithm-scaled fold change derived from qPCR and microarray were calculated in order to determine result repeatability by the two different quantification approaches. Statistically significant results at p<0.05 are marked with asterisk. As no differentially expressed gene was detected by microarray in contrast 1, nor did qPCR yield any statistically significant results existed between the fold change results derived from both methods. In contast 2, a high level of correlation (R2 = 0.9) was found in the fold change values derived from qPCR and microarray, and 6 of the 7 genes (marked with asterisk) were regarded as statistically significant by both quantification methods.
