Metastasis to the brain is a clinical problem in patients with breast cancer (1-3). We mined published microarray data (4, 5) to compare primary and metastatic tumor transcriptomes to discover genes associated with brain metastasis in patients with metastatic breast cancer. We report here the differential expression of the protein kinase AKT1 in the primary tumors and brain metastases of humans with breast cancer. AKT1 mRNA was present at significantly increased quantities in brain metastatic tissues as compared to primary tumors of the breast. These data combined suggest that up-regulation of AKT1 is a conserved event, both during transformation of breast tissues and progression to central nervous system metastasis and further point to potential importance of AKT1 modulation during progression of human breast cancer.

The polyamine biosynthetic enzymes ODC and SAMDC show higher activity in carcinomatous human breast tissue than in uninvolved tissue of the same breast; the interconversion enzyme PAO shows significantly lower activity in carcinomatous than uninvolved tissue. The polyamine metabolism in carcinomatous human breast tissue thus appears to differ from that in uninvolved tissue. Intracellular polyamine concentrations, particularly spermine, are high in carcinomatous tissue. This increase and that of the biosynthetic enzymes suggest that a higher polyamine concentration is needed for carcinomatous cell growth. If this is the case, the lower PAO activity in carcinomatous tissue may be explained as a mechanism that conserves the high intracellular polyamine concentration.
