Figure 4. LCN2 is up-regulated in metastatic PyMT breast cancer cells and associates with poor patient prognosis.

Figure 4

(A) Experimental scheme to determine soluble genes up-regulated in Py230 vs. Py8119 cells that have prognostic relevance. (B) Cytoscape interactome from soluble proteins/genes previously reported by Bao et al. to be upregulated in Py230 cells relative to Py8119 cells. (C) DAVID-generated gene ontology enrichment analysis for all nodes in the interactome in B. (D–F) Cancer BioPortal generated Kaplan-Meier survival curves for breast cancer patients in relation to when LCN2 is genomically amplified in D, is transcriptionally upregulated in E, or is co-amplified with FABP1 in F. (G and H) Human Protein Atlas IHC data for LCN2 and FABP1 in breast cancer tissue. (I) Immunoblot for LCN2 relative to loading control across triplicate protein lysates collected from either Py8119 and Py230 cells. (J) ELISA for LCN2 levels in circulating blood plasma from mice in the experiment outlined in Figure 2A. **** represents a p-value of <0.0001 as determined by student’s T-test.
