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 CD34 when comparing primary tumors of the breast to the tissue of origin, the normal breast. CD34 expression in primary tumors of the breast was significantly lower than in normal breast tissue, and relapse-free and overall survival in breast cancer patients was significantly worse CD34 patients with low tumor expression of CD34 than in patients with high tumor expression of CD34. CD34 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 fibronectin, encoded by FN1, when comparing primary tumors of the breast to the tissue of origin, the normal breast. FN1 expression in primary tumors of the breast was significantly higher than in normal breast tissue, and distant metastasis-free survival in breast cancer patients was significantly worse in patients with high tumor expression of FN1 than in patients with low tumor expression of FN1. FN1 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 the oxytocin receptor, OXTR, when comparing primary tumors of the breast to the tissue of origin, the normal breast. OXTR expression in primary tumors of the breast was significantly lower than in normal breast tissue, and relapse-free survival in breast cancer patients was significantly longer in patients with high tumor expression of OXTR than in patients with low tumor expression of OXTR. OXTR 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 the H3K36 methyltransferase Wolf-Hirschhorn syndrome candidate 1, WHSC1, also known as Nsd2 or KMT3G, when comparing primary tumors of the breast to the tissue of origin, the normal breast. WHSC1 expression in primary tumors of the breast was significantly higher than in normal breast tissue, and relapse-free survival in breast cancer patients was significantly worse in patients with high tumor expression of WHSC1 than in patients with low tumor expression of WHSC1. WHSC1 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 an antisense RNA transcribed from the FGF14 locus, FGF14-AS2, when comparing primary tumors of the breast to the tissue of origin, the normal breast. A coding FGF14 transcript was differentially expressed in the tumor cells of patients with triple negative breast cancer. FGF14-AS2 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 FGF14-AS2 in primary tumors of the breast was correlated with distant metastasis-free survival in patients with HER2+ subtype cancer, demonstrating a relationship between primary tumor expression of a differentially expressed antisense transcript and patient survival outcomes influenced by PAM50 molecular subtype. FGF14-AS2 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 dCTP pyrophosphatase 1, DCTPP1, when comparing primary tumors of the breast to the tissue of origin, the normal breast. DCTPP1 was also differentially expressed in the tumor cells of patients with triple negative breast cancer. DCTPP1 mRNA was present at significantly higher quantities in tumors of the breast as compared to normal breast tissue. Analysis of human survival data revealed that expression of DCTPP1 in primary tumors of the breast was correlated with overall survival in patients with basal subtype cancer. DCTPP1 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 the kinesin family member 11, KIF11, when comparing primary tumors of the breast to the tissue of origin, the normal breast. KIF11 was also differentially expressed in the tumor cells of patients with triple negative breast cancer. KIF11 mRNA was present at significantly higher quantities in tumors of the breast as compared to normal breast tissue. Analysis of human survival data revealed that expression of KIF11 in primary tumors of the breast was correlated with overall survival in patients with basal and luminal A subtype cancer, but in a contrary manner. KIF11 may be of relevance to initiation, maintenance or progression of cancers of the female breast.
