摘要：
The purpose of this study was to evaluate baseline RRM2 protein and gene expression in tumors of patients receiving 3-AP. Tumor blocks from patients enrolled in phase I and II clinical studies using 3-AP, were evaluated for RRM2 gene and protein expression by quantitative real time polymerase chain reaction (Q-RTPCR) and automated quantitative analysis (AQUA). Esophageal and gastric cancers overexpressed RRM2 protein when compared to prostate cancer (Z-score, 0.68 +/- A 0.94 SD, vs 0.41 +/- A 0.84 SD, respectively; p = 0.04). Esophageal and gastric cancers also overexpressed RRM2 mRNA when compared to prostate cancer (relative gene expression 2.56 +/- A 1.49 SD, vs 0.29 +/- A 0.20 SD, respectively; p = 0.02). Protein and gene expression were moderately associated (Spearman's rank correlation = 0.30; p = 0.12). RRM2 gene and protein expression varies by tumor type.
