Correlation between COX-2 mRNA and protein level with mRNA level of various angiogenic factors.

Pearson r (r) and p-value (p) are presented in tumor and adjacent cirrhotic and noncirrhotic liver separately. Statistically significant correlations are shown in bold. Abbreviations: Ang-1/2: angiopoietin-1/2; Tie-2: tyrosine kinase with immunoglobulin-like and EGF-like domains-2; COX-2: Cycloxygenase-2; mRNA: messenger ribonucleic acid; VEGFA: vascular endothelial growth factor A, VEGFR1/R2: vascular endothelial growth factor receptor ½; Tu: tumor; Adj: adjacent.
