Expression of VEGF, COX-2 mRNA in esophageal cancer / 肿瘤研究与临床

ABSTRACT

Objective To study the expression of VEGF isoforms, COX-2 in esophageal cancer Methods VEGF, COX-2 mRNA expression in 40 paired samples (tumor and adjacent normal tissue) were determined by using real time RT-PCR. Results VEGF165 was overexpressed in 25 of 40(62.5 %) tumor tissues compared with in 6 of 40 (15 %) adjacent normal tissue; COX-2 was overexpressed in 28 of 40(70 %) tumor tissues compared with in 5 of 40(12.5 %) adjacent normal tissue. Conclusion This result suggests that VEGF165 and COX-2 overexpression in esophageal cancer.
