Figure 2From: Elevated levels of circulating IL-7 and IL-15 in patients with early stage prostate cancerExpression of IL genes in PCA cell lines Total RNA was extracted from three PCA cell lines: PC-3 DU-145 and LNCaP. Following DNase treatment, RNA were reverse transcribed and resulting cDNA were analysed by quantitative real-time PCR for IL-2, IL-7, IL-15, IL-6 and IL-21 specific gene expression. Data are expressed as ratio to GAPDH gene expression.Back to article page
