Fibroblast-like synoviocytes from patients with rheumatoid arthritis express messenger RNA of multiple KCa1.1 β subunits. a expression fold measurements were conducted by quantitative reverse transcription polymerase chain reaction, compared with GAPDH expression (n = 6 donors with 3 independent repeats). Each bar shows expression of a different KCa1.1 subunit, the letters a–-e represent different transcript variants. b α/β ratio showing the amount of KCa1.1 α subunits expressed for each single β subunit. Note the different scales of the y-axis. ΔcT comparative cycle threshold, GAPDH glyceraldehyde 3-phosphate dehydrogenase
