EGCG decreases the expression of inflammatory and pro-angiogenic factors in PDT-treated BA tumors. Tumor lysates were collected 24 hours after PDT and levels of PGE2 and VEGF (A, B) were determined using EIA kits. MMP enzymatic activity was visualized via gel zymography. Levels of MMP-2 and MMP-9 were determined by densitometry from gelatinolytic bands (C, D). Columns, mean; bars, ± SE; of two separate experiments *, p< 0.05 (PDT versus PDT + EGCG).
