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 for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that neurocan, encoded by NCAN, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. NCAN mRNA was present at increased quantities in brain metastatic tissues as compared to primary tumors of the breast. Importantly, expression of NCAN in primary tumors was significantly correlated with patient recurrence-free survival. Modulation of NCAN expression may be relevant to the biology by which tumor cells metastasize 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 for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that ATPase phospholipid transporting 8A2, encoded by ATP8A2, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. ATP8A2 mRNA was present at increased quantities in brain metastatic tissues as compared to primary tumors of the breast.

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 for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that Bernardinelli-Seip congenital lipodystrophy 2, also known as seipin, encoded by BSCL2, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. BSCL2 mRNA was present at increased quantities in brain metastatic tissues as compared to primary tumors of the breast. Expression of BSCL2 in primary tumors was significantly correlated with patient distant metastasis-free survival. Modulation of BSCL2 expression may be relevant to the biology by which tumor cells metastasize 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 for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that genetic suppressor element 1, encoded by GSE1, also known as KIAA0182, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. GSE1 mRNA was present at increased quantities in brain metastatic tissues as compared to primary tumors of the breast.
