The dot intensity analysis of the phospho tyrosine kinase receptor array suggested an increased level of phosphorylation of epithelial growth factor receptor (EGFR), receptor like tyrosine kinase (RYK), anaplastic lymphoma kinase receptor (ALK), fms tyrosine kinase 3 receptor (FLT-3), ephrin A10 receptor (EPHA10), and v-erb-b2 avian erythroblastic leukemia viral oncogene homolog 2 (ERBB2, HER2) (Fig. 2a and 2b), which are commonly activated in cancer cells [17,18,19,20,21]. The gene discussed is ERBB2; the disease is cancer.
