Metastasis to the brain is a complication of breast cancer (1, 2) with limited treatment options (3). We mined published microarray data (4, 5) to discover genes associated with brain metastases in patients with metastatic breast cancer. We identified significant differential expression of the eukaryotic translation initiation factor TNS1 in the brain metastases of patients with breast cancer as compared to primary tumors of the breast. TNS1 may be relevant to the underlying biology by which tumor cells of the breast spread to the brain.

In patients with breast cancer, brain metastasis provides limited treatment options (1-3). To discover genes associated with brain metastases in patients with metastatic breast cancer, we mined published microarray datasets, comparing global transcription in brain metastases and primary tumors of the breast (4, 5). Using this methodology, we identified significant differential expression of the G0/G1 switch gene 2, encoded by G0S2, in the brain metastases of patients with breast cancer as compared to primary tumors of the breast. The G0S2 gene product could be of relevance to any one of the numerous processes by which tumor cells in breast cancer metastasize, including exit of the breast, entry into the periphery, breach of the blood brain barrier or colonization of and survival in the brain.

Metastasis to the brain is a complication of breast cancer (1, 2) with limited treatment options (3). We mined published microarray data (4, 5) to discover genes associated with brain metastases in patients with metastatic breast cancer. We identified significant differential expression TAX1BP1 in the brain metastases of patients with breast cancer as compared to primary tumors of the breast. TAX1BP1, an HLTV-I Tax-interacting protein with the ability to bind the deubiquitinase A20 and inhibit cell death mediated by Fas and TNF-α pathways (6-10), may be relevant to the underlying biology by which tumor cells of the breast spread to the brain.

Metastasis to the brain is a complication of breast cancer (1, 2) with limited treatment options (3). We mined published microarray data (4, 5) to discover genes associated with brain metastases in patients with metastatic breast cancer. We identified significant differential expression of the gene encoding the vascular endothelial growth factor A, VEGFA, in both the brain metastases and lymph node metastases of patients with breast cancer as compared to primary tumors of the breast. VEGF-A, a molecule described to possess the ability to disrupt the blood-brain barrier (6), may be relevant to the underlying biology by which tumor cells of the breast spread to the lymph nodes and to the brain.

Breast cancer affects women at relatively high frequency (1). We mined published microarray datasets (2, 3) to determine in an unbiased fashion and at the systems level genes most differentially expressed in the primary tumors of patients with breast cancer. We report here significant differential expression of the gene encoding LINC02716, DKFZp779M0652, when comparing primary tumors of the breast to the tissue of origin, the normal breast. DKFZp779M0652 was also differentially expressed in the brain metastases of patients with metastatic breast cancer. DKFZp779M0652 mRNA was present at significantly lower quantities in tumors of the breast as compared to normal breast tissue. DKFZp779M0652 may be of relevance to initiation, maintenance or progression of cancers of the female breast.

Metastasis to the brain is a clinical problem in patients with breast cancer (1-3). We mined published microarray data (4, 5) to discover genes associated with brain metastasis in breast cancer. We identified significant differential expression of cornifelin, encoded by CNFN, in the brain metastases of patients with metastatic breast cancer. Increased expression of CNFN observed in brain metastatic tissues may be pertinent to understanding the biology underlying colonization of the brain with metastatic breast cancer clones.

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.

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 found that the fibroblast growth factor 12, encoded by FGF12, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to normal breast tissues. FGF12 mRNA expression was significantly higher in brain metastatic tissues as compared to primary tumors of the breast. Up-regulation of FGF12 expression may contribute to metastasis of tumor cells from the breast to the brain in humans with metastatic breast cancer.

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 found that the complement component 1, r subcomponent, encoded by C1R, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to normal breast tissues. C1R mRNA was present at significantly reduced quantities in brain metastatic tissues as compared to primary tumors of the breast. Down-regulation of C1R expression may contribute to metastasis of tumor cells from the breast to the brain in humans with metastatic breast cancer.
