Inhibition of hypoxia-induced VEGF proteins in T47D cells. (A) VEGF protein levels in the cell lysates were determined by ELISA and normalized to the amount of cellular protein. Data shown are from one representative experiment performed in triplicate and the bars represent standard errors. An asterisk (*) indicates a significance of p < 0.05 when compared to the untreated control “C.” The compounds were tested at the following concentrations: 1 (1 µM); 2 (3 µM); 4 (0.3 µM); and 5 (10 µM). All compounds exhibited statistically significant (p < 0.05) inhibition of VEGF protein induction by hypoxia. (B) Secreted VEGF protein levels in the conditioned media were determined by ELISA. Compound treatments and data presentation are as described for (A).
