CD44 and neoplasm: Since we previously observed a strong effect of holo-LCN-2 on tumour cell migration (Fig. 5), we then performed qRT-PCR analysis of migration-associated genes, such as the transcription factor Snail (Fig. 6c), the epithelial marker CDH1 (Fig. 6d), the mesenchymal marker fibronectin (Fig. 6e) as well as the stemness markers CD24 (Fig. 6f) and CD44 (Fig. 6g).
