Bieche et al. [20] exhibited that the relative mRNA expression of CXCL3 was higher in the tissues of grade I invasive breast cancer, grade III invasive breast cancer, and distal metastatic breast cancer than in the normal breast cancer, and then the relative mRNA expression of CXCL3 was the highest in distal metastatic breast cancer. This evidence concerns the gene CXCL3 and invasive breast carcinoma.
