Abstract
- PURPOSE
To investigate the effect of bevacizumab, a monoclonal antibody against vascular endothelial growth factor (VEGF), on the survival and production of nitric oxide (NO) in human trabecular meshwork cells (HTMC). METHODS: Primarily cultured HTMC were exposed to 0, 0.25, 1.0, and 2.5 mg/ml bevacizumab for 24 hours. Cellular survival and production of NO were assessed by MTT assay and Griess assay, respectively. RESULTS: Bevacizumab did not affect the cellular survival at low concentrations but decreased cellular survival significantly at high concentrations (>1.0 mg/ml) accompanied with increased NO production. CONCLUSIONS: High concentrations of bevacizumab may be toxic to HTMC.
