Breast cancer patients diagnosed with metastasis to the brain (1-3) are presented limited treatment options (4, 5). We mined published microarray data (6, 7) to discover genes associated with brain metastasis in human breast cancer at the transcriptome-level and in an unbiased fashion. We describe here the differential expression of the long intergenic non-coding RNA LINC00968 in the brain metastatic tissues and primary tumors of women with breast cancer. LINC00968 transcript was present at significantly reduced quantities at in brain metastases and in primary tumors of the breast as compared to untransformed breast tissues. Molecular functions and down-regulation of LINC00968, a non-coding RNA that has not previously been described in relation to central nervous system metastasis in human breast cancer represents a feature of the transcriptional fingerprint of brain metastatic breast cancer in humans and may be relevant to pathways underlying invasion and colonization of the brain.

Breast cancer patients diagnosed with metastasis to the brain (1-3) are presented limited treatment options (4, 5). We mined published microarray data (6, 7) to discover genes associated with brain metastasis in human breast cancer, and identified differential expression of RNF186 when comparing brain metastatic tissues to primary tumors of the breast. RNF186 was expressed at significantly lower levels in metastasis to the brain as compared to primary tumors. Molecular functions and down-regulation of RNF186, a ring finger E3 ligase that can modulate endoplasmic reticulum-stress pathway signaling (8) may be relevant to pathways underlying metastasis to the brain in human breast cancer.

Breast cancer patients diagnosed with metastasis to the brain (1-3) are presented limited treatment options (4, 5). We mined published microarray data (6, 7) to discover genes associated with brain metastasis in human breast cancer, and identified differential expression of the gene encoding asporin, ASPN, when comparing brain metastatic tissues to primary tumors of the breast. ASPN was expressed at significantly lower levels in metastasis to the brain as compared to primary tumors, and primary tumor expression of ASPN was significantly correlated with overall survival (8). Asporin (9) , its ability to interact with TGF-β (10) and type I collagen (11), and inhibition of these interactions through down-regulation of asporin expression may be relevant to pathways underlying metastasis to the brain in 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 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 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.

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.
