Lipocalin 2 (Lcn2), a member of the lipocalin family that carries small lipophilic ligands, has
gained recent attention as both a potential biomarker and a modulator of human cancers.
Here we describe recent findings of the functions of Lcn2 in breast cancer and the potential
mechanisms that underlie its actions. Lcn2 has been shown to induce the epithelial to
mesenchymal transition (EMT) in breast cancer cells and to promote breast tumor invasion.
Estrogen receptor α may participate in the pathway that leads to Lcn2-induced EMT …
Lipocalin 2 (Lcn2), a member of the lipocalin family that carries small lipophilic ligands, has gained recent attention as both a potential biomarker and a modulator of human cancers. Here we describe recent findings of the functions of Lcn2 in breast cancer and the potential mechanisms that underlie its actions. Lcn2 has been shown to induce the epithelial to mesenchymal transition (EMT) in breast cancer cells and to promote breast tumor invasion. Estrogen receptor α may participate in the pathway that leads to Lcn2-induced EMT. Preliminary evidence also suggests that Lcn2 may be used as a potential non-invasive urinary biomarker of breast cancer. Elevated levels of Lcn2 have also been reported in other human cancers. The potential roles of Lcn2 in some other epithelial tumors as well as leukemia are also reviewed and discussed here.
