Effects of CML or pentosidine at 0 (control), 1, 2, 4, 8 or 16 μmol/L upon protein expression of RAGE, p47^phox and gp91^phox in human A549 and Calu-6 cells. Cells were exposed to CML or pentosidine for 18 h at 37 °C. Data are mean ± SD (n = 10) and shown in the following table. ^a–d Means within a column without a common letter differ, p < 0.05.
