Fig. 4.

Phospho-kinase array analysis of phenol or m-cresol treated L929 cells. L929 cells were treated with 1 mg/ml phenol or m-cresol for 30 min. Cell lysates were prepared and incubated with a phospho-kinase array. Untreated cells served as controls. Left: images of the arrays (untreated, phenol- or m-cresol-treated cells). Right: densitometric analysis of the arrays. The mean intensity of two array spots is depicted to illustrate the relative induction of kinase phosphorylation in phenol or m-cresol treated cells versus untreated cells.
