Fig. 4. Cellular kinases activated by ZIP7 overexpression or zinc treatment. MCF-7 cells were transfected with or without wild-type ZIP7 and treated with or without zinc for 10 minutes. Tyrosine phosphorylation of selected RTKs and site-specific phosphorylation of selected kinases were determined using the phospho-RTK (A), phospho-kinase (B), and phospho-MAPK (C) arrays (R&D systems). Average densitometric values are presented as a spectrum of colour where blue and red colours represent the lowest and the highest values in the row according to the indicated scale.
