ANGPT2 and neoplasm: The analysis of a correlation between protein and gene expression of both angiopoietins showed no correlation between ANG-1 protein expression in the aqueous humor and ANG-1 mRNA expression in tumor material (rS = 0.02, p = 0.89) (Figure 3A), but it did show a positive correlation between ANG-2 protein expression and mRNA expression (rS = 0.31, p = 0.03) (Figure 3B).
