Differential expression of LINC02716 in cancers of the 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 LINC02716, DKFZp779M0652, when comparing primary tumors of the breast to the tissue of origin, the normal breast. DKFZp779M0652 was also differentially expressed in the brain metastases of patients with metastatic breast cancer. DKFZp779M0652 mRNA was present at significantly lower quantities in tumors of the breast as compared to normal breast tissue. DKFZp779M0652 may be of relevance to initiation, maintenance or progression of cancers of the female breast.
