Short-term (4-h) effects of cyclosporine A on with-no-lysine [K] kinase (WNK) 1, WNK3, SPAK, OSR1, NKCC2, NCC, and cyclooxygenase (COX)-2 mRNA expression in kidney lysates from rats treated with vehicle or cyclosporine A for 4 h. Quantitative PCR; all results were normalized to GAPDH expression. Data are means ± SE; *P < 0.05.
