Exogenous WNK2 expression inhibits colony formation by malignant meningioma cell lines. IOMM-Lee and KT21-MG1 cells were each transfected with equimolar amounts of WNK2 expression vector or vector only. Cells were selected with G 418 (an antibiotic called Geneticin, used to select cells positive for WNK2 constructs) for 10–14 days before staining with crystal violet. Colonies of >50 cells were counted. Quantitation of total colony numbers from each cell line is shown; error bars, standard deviation (SD).
