Figure 8

Time-dependent effects of lipopolysaccharide (LPS) on the expressions of surfactant protein-A (SP-A) mRNA and protein. HK-2 cells were exposed to 5 μg/mL of LPS for 0, 2, 4, 8, 16, and 24 h. (A) Gel electrophoresis of SP-A1 and SP-A2 mRNA. (B) Comparison of SP-A1 and SP-A2 mRNA after exposure to 5 μg/mL of LPS at different time points. (C) Comparison of SP-A protein after exposure to 5 μg/mL of LPS at different time points. Each value represents the mean ± SEM for n = 3. The symbol “a” indicates that the value significantly (P < 0.05) differed from the control group. M, 100 bp DNA marker.
