Metastasis to the brain is a clinical problem in patients with breast cancer (1-3). Between the brain and the breast resides the secondary lymphoid organ, the lymph nodes. We mined published microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with metastasis to the lymph nodes in human breast cancer. We found that the defensin beta 123, encoded by DEFB123, was among the genes whose expression was most different in the lymph nodes metastases of patients with metastatic breast cancer as compared to primary tumors of the breast (4). DEFB123 was also differentially expressed in the primary tumors of the breast when compared to normal mammary epithelium (5). DEFB123 mRNA was present at increased quantities in lymph node metastatic tissues as compared to primary tumors of the breast. Importantly, expression of DEFB123 in primary tumors was significantly correlated with patient overall survival in patients with lymph node negative breast cancer. Modulation of DEFB123 expression may be relevant to the biology by which tumor cells metastasize from the breast to the lymph nodes in humans with metastatic breast cancer.

Metastasis to the brain is a clinical problem in patients with breast cancer (1-3). Between the brain and the breast resides the secondary lymphoid organ, the lymph nodes. We mined published microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with metastasis to the lymph nodes in human breast cancer. We found that the SP140 nuclear body protein like, encoded by SP140L, was among the genes whose expression was most different in the lymph nodes metastases of patients with metastatic breast cancer as compared to primary tumors of the breast (4). SP140L was also differentially expressed in the tumor cells of patients with triple negative breast cancer (5). SP140L mRNA was present at increased quantities in lymph node metastatic tissues as compared to primary tumors of the breast. Importantly, expression of SP140L in primary tumors was significantly correlated with patient overall survival, in lymph node positive patients but not in lymph node negative patients. Modulation of SP140L expression may be relevant to the biology by which tumor cells metastasize from the breast to the lymph node and to the brain in humans with metastatic breast cancer.

Metastasis to the brain is a clinical problem in patients with breast cancer (1-3). Between the brain and the breast resides the secondary lymphoid organ, the lymph nodes. We mined published microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with metastasis to the lymph nodes in human breast cancer. We found that the coiled-coil domain containing 155, encoded by CCDC155, was among the genes whose expression was most different in the lymph nodes metastases of patients with metastatic breast cancer as compared to primary tumors of the breast (4). CCDC155 was also differentially expressed in the tumor cells of patients with triple negative breast cancer (5). CCDC155 mRNA was present at increased quantities in lymph node metastatic tissues as compared to primary tumors of the breast. Importantly, expression of CCDC155 in primary tumors was significantly correlated with patient recurrence-free survival, in lymph node positive patients but in lymph node negative patients. Modulation of CCDC155 expression may be relevant to the biology by which tumor cells metastasize from the breast to the lymph node and to the brain in humans with metastatic breast cancer.

Metastasis to the brain is a clinical problem in patients with breast cancer (1-3). Between the brain and the breast resides the secondary lymphoid organ, the lymph nodes. We mined published microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with metastasis to the lymph nodes in human breast cancer. We found that the zinc finger protein 367, encoded by ZNF367, was among the genes whose expression was most different in the lymph nodes metastases of patients with metastatic breast cancer as compared to primary tumors of the breast4. ZNF367 was also differentially expressed in the tumor cells of patients with triple negative breast cancer5. ZNF367 mRNA was present at increased quantities in lymph node metastatic tissues as compared to primary tumors of the breast. Importantly, expression of ZNF367 in primary tumors was significantly correlated with patient distant metastasis-free survival, in lymph node negative but not in lymph node positive breast cancer. Modulation of ZNF367 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). Between the brain and the breast resides the secondary lymphoid organ, the lymph nodes. We mined published microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with metastasis to the lymph nodes in human breast cancer. We found that translin associated factor X interacting protein 1, encoded by TSNAXIP1, was among the genes whose expression was most different in the lymph nodes metastases of patients with metastatic breast cancer as compared to primary tumors of the breast4. TSNAXIP1 was also differentially expressed in the tumor cells of patients with triple negative breast cancer5. TSNAXIP1 mRNA was present at decreased quantities in lymph node metastatic tissues as compared to primary tumors of the breast. Importantly, expression of TSNAXIP1 in primary tumors was significantly correlated with patient overall survival, in lymph node positive patients but in lymph node negative patients. Modulation of TSNAXIP1 expression may be relevant to the biology by which tumor cells metastasize from the breast to the lymph node and to the brain in humans with metastatic breast cancer.

We mined published microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with metastasis to the lymph nodes in humans with metastatic breast cancer. We found that teashirt zinc finger homeobox 3, TSHZ3, was among the genes whose expression was most different in the lymph node metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. Analysis of a separate microarray dataset revealed that TSHZ3 was also differentially expressed in brain metastatic tissues. TSHZ3 mRNA was present at decreased quantities in lymph node metastases as compared to primary tumors of the breast. Importantly, expression of TSHZ3 in primary tumors of the breast was correlated with patient post-progression survival, in lymph node positive patients but not in lymph node negative patients. Modulation of TSHZ3 expression may be relevant to the biology by which tumor cells metastasize from the breast to the lymph nodes and the brain in humans with metastatic breast cancer.
