Expression of mRNA for Lcn2, Mmp9, Bdh2, 24p3R, megalin (another receptor mediating cellular uptake of lipocalin-2 [51]), and transferrin receptor (Tfrc) were determined in each tumor and reported as mean of all tumors/tissue samples in each of the four groups of mice (Figure 5). The gene discussed is LRP2; the disease is neoplasm.
