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 taspase 1, encoded by TASP1, was among the genes whose expression was most quantitatively different in the brain metastases of patients with metastatic breast cancer. TASP1 mRNA was present at decreased quantities in brain metastatic tissues as compared to primary tumors of the breast. Importantly, expression of TASP1 in primary tumors was significantly correlated with patient overall survival in patients with breast cancer. Modulation of TASP1 expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain.

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 palladin, encoded by PALLD, was among the genes whose expression was most quantitatively different in the brain metastases of patients with metastatic breast cancer. PALLD mRNA was present at decreased quantities in brain metastatic tissues as compared to primary tumors of the breast. Importantly, expression of PALLD in primary tumors was significantly correlated with patient overall survival in patients with breast cancer. Modulation of PALLD expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain.

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 tropomyosin 4, encoded by TPM4, was among the genes whose expression was most quantitatively different in the brain metastases of patients with metastatic breast cancer. TPM4 mRNA was present at decreased quantities in brain metastatic tissues as compared to primary tumors of the breast. Importantly, expression of TPM4 in primary tumors was significantly correlated with patient overall survival in patients with 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 asparagine synthetase domain containing 1, encoded by ASNSD1, 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. ASNSD1 mRNA was present at decreased quantities in brain metastatic tissues as compared to primary tumors of the breast. Importantly, expression of ASNSD1 in primary tumors was significantly correlated with patient post-progression survival. Modulation of ASNSD1 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 grainyhead-like transcription factor 3, encoded by GRHL3, 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. GRHL3 mRNA was present at increased quantities in brain metastatic tissues as compared to primary tumors of the breast. Importantly, expression of GRHL3 in primary tumors was significantly correlated with patient overall survival. Modulation of GRHL3 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 sprouty homolog 2, encoded by SPRY2, was among the genes whose expression was most quantitatively different in the brain metastases of patients with metastatic breast cancer. SPRY2 mRNA was present at decreased quantities in brain metastatic tissues as compared to primary tumors of the breast. Importantly, expression of SPRY2 in primary tumors was significantly correlated with patient recurrence-free survival in patients with breast cancer. Modulation of SPRY2 expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain.
