As immunohistochemistry was not able to discriminate LOX-1 and LOX-1Δ4 proteins, we analyzed mRNA expression obtained from nine breast cancer samples (three out of nine luminal A, three triple negative, three HER-2 enriched) of same individuals previously characterized by immunohistochemistry, as shown in Fig. 3a. This evidence concerns the gene OLR1 and breast carcinoma.
