Correlation between the miRNA expression level and EAC tumor stage.

<p>The expression levels of the 4 miRNAs (miR-203, miR-194, miR-192, and miR-200a) were evaluated in EAC tissue samples of stages I, II and III by means of qRT-PCR. The data is expressed as the log10 FC relative to miR-191. Each data point represents a different patient tissue sample. ANOVA was used for statistical analysis of the difference in miRNA expression across the 3 stages. Student t-test was used for statistical analysis between stages I&II, stages II&III, and stages I&III. A p value ≤0.05 was considered statistically significant.
