Figure 1D shows that LOX mRNA levels are low in Ewing primary tumors compared to those observed in IMR90 cells. In addition, we searched public expression datasets in order to analyse the relative expression of LOX in Ewing sarcoma in relation to other tumor types. As shown in supplementary figure S1, LOX expression was low in Ewing sarcoma tumors, compared to other neoplasms. Here, LOX is linked to Ewing sarcoma.
