Transcription profiling of human lens epithelial cells to examine glucocorticoid induced changes

ABSTRACT: Prolonged use of glucocorticoids can lead to the formation of a cataract, however the mechanism is not known. We recently reported the presence of the functional glucocorticoid receptor in immortalized cultured mammalian lens epithelial cells (Gupta & Wagner, Invest Ophthalmol Vis Sci 2003), but the short term biological effect of glucocorticoid action in lens epithelial cells is not known. This study seeks to examine glucocorticoid induced changes in global gene expression in LECs. RNA isolated from HLE B-3 cells, treated with Dex or Veh for 4 or 16 hours, was used to analyze global changes in gene expression by microarray hybridization. Microarray studies at 2 time periods demonstrate that glucocorticoids modulate gene expression in immortalized human LECs, reveal novel changes in gene
