From: Lipocalin 2 promotes lung metastasis of murine breast cancer cells
Effects of lipocalin 2 on tumor formation and lung metastases. Murine were killed and analyzed at the end of 30 days post tumor implantation. (A) Upper panels: representative photos of the lungs. The arrows point to the metastatic nodules in lungs. Lower panels: the average numbers of lung metastatic nodules. (B) Primary tumor weights. (C) Upper panels: semiquantitative RT-PCR analysis of lipocalin 2 expression in primary tumors. Lower panels: quantitation of lipocalin 2 was performed after normalization with the β-actin. *P < 0.05, **P < 0.01.
