Correlation of the expression of the RNA (FFPE) and the RNA (FF) of 11 matched FF-FFPE samples. The four genes (EMP3, SLC2A10, SUSD5, CSMD3) chosen are the most discriminating genes between two very distinct molecular subtypes. (A) The correlation between the ΔCt of the qPCR results (FFPE material) and the expression data of the HU133plus 2.0 arrays (FF tissue). A high ΔCt value is indicative for a low expression value. The correlation plot shows a good correlation between the FF expression and the FFPE expression. (B) This correlation view shows the correlation of the expression of the FF tissue (HU133 plus 2.0 array) and the expression of the FFPE tissue (qPCR). The green color represents low expression, red represents high expression. The molecular clusters can be identified using the RNA isolated from FFPE.
