Figure S2. Further examples of the effect of the H2S donor, NaSH on CBS and MPST protein expression, and activation of extracellular signal–regulated kinase (ERK)–1/2 and p38 mitogen-activated protein kinase (MAPK) in human ASM cells from non-smokers, smokers and COPD patients. ASM cells were incubated with FCS (2.5%) for 1 h and NaSH (100 μM) was added for another 24 h. CBS, MPST (A), Total and phospho–ERK-1/2, total and phospho-p38 and β-actin (B) were detected by Western blotting. (JPG 212 kb)
