Fig. 1. Effect of serum stimulation on ERK proteins in serum-starved RTHDF cells. (A) Top: western blot analysis of phosphorylation of p44ERK and p38ERK during serum stimulation of serum starved cells. The antibody recognises amino acids Thr202 and Tyr204. Bottom: western blot analysis of total ERK protein. (B) Quantification of the phospho-specific immunoreactions representing active p44ERK in RTHDF cells. (C) Quantification of the phospho-specific immunoreactions representing active p38ERK in RTHDF cells (N=4, *P<0.05).
