Fig. 3.From: Reactive Oxygen-induced Carcinogenesis Causes Hypermethylation of p16Ink4a and Activation of MAP KinaseWestern blot analysis of cell lines derived from nickel sulfide induced malignant fibrous histiocytomas showing expression of phosphorylated MAP kinase with β-actin as a loading control. Levels of phosphorylation are compared with MS1 (lane 1). P53Nis1 cell lysates are in lane 2, and C57Nis1,2,3 are in lanes 3,4, and 5 respectively.Back to article page
