Breast cancer affects women at relatively high frequency (1). We mined published microarray datasets (2, 3) to determine in an unbiased fashion and at the systems level genes most differentially expressed in the primary tumors of patients with breast cancer. We report here significant differential expression of the gene encoding T-box 15, TBX15, when comparing primary tumors of the breast to the tissue of origin, the normal breast. TBX15 was also differentially expressed in the brain metastases of patients with metastatic breast cancer. TBX15 mRNA was present at significantly lower quantities in tumors of the breast as compared to normal breast tissue. Analysis of human survival data revealed that expression of TBX15 in primary tumors of the breast was correlated with recurrence-free survival in patients with basal-like and normal-like subtype cancer, demonstrating a relationship between primary tumor expression of a differentially expressed gene and patient survival outcomes influenced by PAM50 molecular subtype. TBX15 may be of relevance to initiation, maintenance or progression of cancers of the female breast.

Breast cancer affects women at relatively high frequency (1). We mined published microarray datasets (2, 3) to determine in an unbiased fashion and at the systems level genes most differentially expressed in the primary tumors of patients with breast cancer. We report here significant differential expression of the gene encoding transmembrane protein 132C, TMEM132C, when comparing primary tumors of the breast to the tissue of origin, the normal breast. TMEM132C was also differentially expressed in the brain metastases of patients with metastatic breast cancer. TMEM132C mRNA was present at lower quantities in tumors of the breast as compared to normal breast tissue. Analysis of human survival data revealed that expression of TMEM132C in primary tumors of the breast was correlated with distant metastasis-free survival in patients with luminal B subtype cancer, demonstrating a relationship between primary tumor expression of a differentially expressed gene and patient survival outcomes influenced by PAM50 molecular subtype. TMEM132C may be of relevance to initiation, maintenance or progression of cancers of the female breast.

Breast cancer affects women at relatively high frequency (1). We mined published microarray datasets (2, 3) to determine in an unbiased fashion and at the systems level genes most differentially expressed in the primary tumors of patients with breast cancer. We report here significant differential expression of the gene encoding placenta-specific 9, PLAC9, when comparing primary tumors of the breast to the tissue of origin, the normal breast. PLAC9 was also differentially expressed in the brain metastases of patients with metastatic breast cancer. PLAC9 mRNA was present at significantly lower quantities in tumors of the breast as compared to normal breast tissue. Analysis of human survival data revealed that expression of PLAC9 in primary tumors of the breast was correlated with distant metastasis-free survival in patients with luminal A subtype cancer, demonstrating a relationship between primary tumor expression of a differentially expressed gene and patient survival outcomes influenced by PAM50 molecular subtype. PLAC9 may be of relevance to initiation, maintenance or progression of cancers of the female breast.

Breast cancer affects women at relatively high frequency (1). We mined published microarray datasets (2, 3) to determine in an unbiased fashion and at the systems level genes most differentially expressed in the primary tumors of patients with breast cancer. We report here significant differential expression of the gene encoding PQ loop repeat-containing 2-like, PQLC2L, when comparing primary tumors of the breast to the tissue of origin, the normal breast. PQLC2L was also differentially expressed in the brain metastases of patients with metastatic breast cancer. PQLC2L mRNA was present at significantly lower quantities in tumors of the breast as compared to normal breast tissue. Analysis of human survival data revealed that expression of PQLC2L in primary tumors of the breast was correlated with recurrence-free survival in patients with luminal A subtype cancer, demonstrating a relationship between primary tumor expression of a differentially expressed gene and patient survival outcomes influenced by PAM50 molecular subtype. PQLC2L may be of relevance to initiation, maintenance or progression of cancers of the female breast.

Breast cancer affects women at relatively high frequency (1). We mined published microarray datasets (2, 3) to determine in an unbiased fashion and at the systems level genes most differentially expressed in the primary tumors of patients with breast cancer. We report here significant differential expression of the gene encoding tetraspanin 3, TSPAN3, when comparing primary tumors of the breast to the tissue of origin, the normal breast. TSPAN3 was also differentially expressed in the brain metastases of patients with metastatic breast cancer. TSPAN3 mRNA was present at significantly lower quantities in tumors of the breast as compared to normal breast tissue. Analysis of human survival data revealed that expression of TSPAN3 in primary tumors of the breast was correlated with distant metastasis-free survival in patients with basal-like subtype cancer, demonstrating a relationship between primary tumor expression of a differentially expressed gene and patient survival outcomes influenced by PAM50 molecular subtype. TSPAN3 may be of relevance to initiation, maintenance or progression of cancers of the female breast.

Breast cancer affects women at relatively high frequency (1). We mined published microarray datasets (2, 3) to determine in an unbiased fashion and at the systems level genes most differentially expressed in the primary tumors of patients with breast cancer. We report here significant differential expression of the gene encoding ELMO domain-containing 3, ELMOD3, when comparing primary tumors of the breast to the tissue of origin, the normal breast. ELMOD3 was also differentially expressed in the brain metastases of patients with metastatic breast cancer. ELMOD3 mRNA was present at significantly lower quantities in tumors of the breast as compared to normal breast tissue. Analysis of human survival data revealed that expression of ELMOD3 in primary tumors of the breast was correlated with recurrence-free survival in patients with basal, luminal A, and luminal B subtype cancer, demonstrating a relationship between primary tumor expression of a differentially expressed gene and patient survival outcomes influenced by PAM50 molecular subtype. ELMOD3 may be of relevance to initiation, maintenance or progression of cancers of the female breast.

Breast cancer affects women at relatively high frequency (1). We mined published microarray datasets (2, 3) to determine in an unbiased fashion and at the systems level genes most differentially expressed in the primary tumors of patients with breast cancer. We report here significant differential expression of the gene encoding Rhox homeobox family member 1, RHOXF1, when comparing primary tumors of the breast to the tissue of origin, the normal breast. RHOXF1 was also differentially expressed in the brain metastases of patients with metastatic breast cancer. RHOXF1 mRNA was present at significantly lower quantities in tumors of the breast as compared to normal breast tissue. Analysis of human survival data revealed that expression of RHOXF1 in primary tumors of the breast was correlated with overall survival in patients with luminal B subtype cancer, demonstrating a relationship between primary tumor expression of a differentially expressed gene and patient survival outcomes influenced by PAM50 molecular subtype. RHOXF1 may be of relevance to initiation, maintenance or progression of cancers of the female breast.
