Brain metastases are 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 patients with brain metastatic breast cancer. We found that the gene encoding the peptide apelin, APLN, was among those most differentially expressed in the brain metastases of patients with brain metastatic breast cancer. APLN may be of relevance to the biology underlying metastasis to the brain in humans with metastatic breast cancer.

Brain metastases are a clinical problem in patients with breast cancer (3-5). We mined published microarray data (6-8) to discover genes associated with brain metastasis in patients with brain metastatic breast cancer. We found that the gene encoding the methyl CpG-binding protein MeCP2, a molecule with critical epigenetic functions in the brain (9, 10), was among the genes most differentially expressed in the brain metastases of patients with brain 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 that an uncharacterized locus, CTC-338M12.4 (LOC101928649), 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. CTC-338M12.4 was also differentially expressed in primary tumors of the breast when compared to normal breast tissue. CTC-338M12.4 mRNA was present at significantly higher quantities in brain metastases as compared to primary tumors of the breast. Molecular functions and up-regulation of CTC-338M12.4 may be an important event for metastasis of primary tumor-derived cancer cells 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 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.
