ITGA1 and breast carcinoma: Comparison with previous measurements of gene expression changes in radiation-induced SD rat mammary carcinoma [24] (S2 Fig) supports downregulation of Fas, Sfrp5 (chromosome 1q52–54), Itga1 (chromosome 2q12–15), Meis2, B2m, Mal (chromosome 3q31–42), Id3, C1qa, and Nbl1 (chromosome 5), reinforcing the role of these genes as potential tumor suppressors.
