Fig 3. Effects of TNFα, IL-1β and LPS on p-ERK1/2 and p-p38MAPK expression in hCMEC/D3 cells.

Fig 3

Cells were treated with or without TNFα (A, B, C), IL-1β (D) and LPS (E) for 15, 30 min and 1, 2, 4, 6 hours. Cell lysates were collected and phospho-ERK1/2 (P- ERK), total ERK1/2 (T-ERK), phospho-p38MAPK (P-P38), total p38MAPK (T-P38) and β-actin expression pattern were analyzed by immunoblotting assay. Quantification of phospho-proteins was determined through assay of PIphospho/PItotal/PIβ-actin and then normalized to control. Results of (B) and (C) are mean ± SD from 4 or more experiments and data are analyzed by one-way ANOVA followed by Bonferroni post-tests **P<0.01, ***P<0.001 compared with no treatment control). Results of (D) and (E) are representation of two repeated experiments.
