Expression of NGAL mRNA, miR-138 and the NGAL protein in three different cancer cell lines.

<p>(A) NGAL mRNA levels measured by qPCR; (B) miR-138 expression levels measured using the TaqMan MicroRNA assay; and (C) detection of intracellular and extracellular NGAL protein determined by western blot analysis in the three cancer cell lines, MCF-7, RL95-2 and AsPC-1.
