Abstract
This study demonstrates that the trabecular meshwork cells of the human eye incorporate 3H-Proline into collagen during in vitro incubation. Addition of dexamethasone to the incubation mixture produced a marked decrease in this incorporation. Dexamethasone was active at 10(-8) M and higher concentrations. The specificity of the hormone effect was demonstrated by its inability to alter 3H-leucine incorporation in these cells. These results indicate that dexamethasone decreases the synthesis of collagen, a major component of the extracellular matrix, in the trabecular meshwork.
