Fig 6. Effect of LPS on dexamethasone induction of MKP-1 and GILZ protein expression.
Quantification of MKP-1 (A) and GILZ (B) proteins in NM fibroblasts (n = 4–5) pre-incubated with 10% FBS (A) or 10% csFBS-supplemented medium (B) with/without LPS (10 μg/ml, 24 hours) prior to dexamethasone (DEX, 10–7 M) addition for the indicated times. *P<.05 and **P<.01 versus untreated cells (0 hours).
