Genome-scale overview of the microarray data revealed that expression changes in the three tumor models of K19-C2mE, K19-Wnt1/C2mE and K19-Nog/C2mE were quite similar, whereas overexpression of Wnt1 only or Nog only led to the expression changes in a small portion of genes (Figure 1). The gene discussed is WNT1; the disease is neoplasm.
