DNA repair protein expression in tumors. A. Western blot determination of p53, XPC, XPA, ERCC1 and MSH2 in tumors. GAPDH is loading control. B. Densitometry analyses of (a) p53, (b) XPC, (c) XPA, (d) ERCC1 and (e) MSH2 normalized to GAPDH loading control and untreated tumors. Mice were perfused for 1 h with cisplatin (CP/37; CP/43) or cisplatin plus NaAsO2 (CPA/37; CPA/43) at 37 or 43°C respectively. Tumors from untreated (UT) mice and treated mice were harvested 0 and 24 h after treatment. Protein extracts were prepared from the tumors and 20 μg loaded per lane for SDS-PAGE. Data are presented as means ± SD of ≥5 tumors each from different mice. Statistical analysis was performed using wilcoxon rank sum test. P < 0.05, N ≥ 5. # = compared to 0 h partner, * = compared to UT.
