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 fibroblast growth factor 2, FGF2, when comparing primary tumors of the breast to the tissue of origin, the normal breast. FGF2 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 FGF2 in primary tumors of the breast was correlated with overall survival in patients with luminal A cancers, demonstrating a relationship between primary tumor expression of a differentially expressed gene and patient survival outcomes influenced by molecular subtype. FGF2 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 c-fos induced growth factor, FIGF, when comparing primary tumors of the breast to the tissue of origin, the normal breast. FIGF was also differentially expressed in the tumor cells of patients with triple negative breast cancer. FIGF 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 FIGF in primary tumors of the breast was correlated with overall 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 molecular subtype. FIGF 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 platelet-derived growth factor D, PDGFD, when comparing primary tumors of the breast to the tissue of origin, the normal breast. PDGFD was also differentially expressed in the tumor cells of patients with triple negative breast cancer. PDGFD 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 PDGFD in primary tumors of the breast was correlated with overall survival in patients with basal and luminal A subtype cancer, demonstrating a relationship between primary tumor expression of a differentially expressed gene and patient survival outcomes influenced by molecular subtype. PDGFD may be of relevance to initiation, maintenance or progression of cancers of the female breast.

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 platelet-derived growth factor receptor alpha, PDGFRA, when comparing primary tumors of the breast to the tissue of origin, the normal breast. PDGFRA 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 PDGFRA in primary tumors of the breast was correlated with overall survival in patients with luminal A cancers, demonstrating a relationship between primary tumor expression of a differentially expressed gene and patient survival outcomes influenced by molecular subtype.

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 insulin-like growth factor binding protein 6, IGFBP6, when comparing primary tumors of the breast to the tissue of origin, the normal breast. IGFBP6 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 IGFBP6 in primary tumors of the breast was correlated with overall survival in patients with basal and luminal A subtype cancers in a contrary manner, demonstrating a complex relationship between primary tumor expression of a differentially expressed gene and patient survival outcomes influenced by molecular subtype. IGFBP6 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 LIM domain binding 2, LDB2, when comparing primary tumors of the breast to the tissue of origin, the normal breast. LDB2 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 LDB2 in primary tumors of the breast was correlated with recurrence-free survival in patients with luminal A subtype cancers, demonstrating a relationship between primary tumor expression of a differentially expressed gene and patient survival outcomes influenced by molecular subtype. LDB2 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 Rho GTPase-activating protein 20, ARHGAP20, when comparing primary tumors of the breast to the tissue of origin, the normal breast. ARHGAP20 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 ARHGAP20 in primary tumors of the breast was correlated with overall survival in patients with HER2+ subtype cancer, demonstrating a relationship between primary tumor expression of a differentially expressed gene and patient survival outcomes influenced by PAM50 molecular subtype. ARHGAP20 may be of relevance to initiation, maintenance or progression of cancers of the female breast.

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 CDC28 protein kinase regulatory subunit 2, CKS2, when comparing primary tumors of the breast to the tissue of origin, the normal breast. CKS2 was also differentially expressed in the tumor cells of patients with triple negative breast cancer. CKS2 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 CKS2 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. CKS2 may be of relevance to initiation, maintenance or progression of cancers of the female breast.
