VEGF mRNA expression in ulcerated (UL) and nonulcerated esophageal tissue from sham-operated (SO) rats detected by RT-PCR. Tissues were obtained 1, 3, and 7 days after ulcer induction or sham operation. Top: RT-PCR products obtained with use of specific primers that recognize all four isoforms of VEGF mRNA (196 bp) and primers that recognize rat β-actin. Bottom: Quantitative data for VEGF mRNA expression. Data were obtained by computerized analysis of amplified PCR products. Each signal was normalized against the corresponding β-actin signal and the results are expressed as a ratio of VEGF/β-actin. Values are means ± SD. For each column, n = 6.
