One-way scatterplots of selected statistically different signaling end points between brain metastases from breast and lung cancers. (A) Selected signaling end points from Table 2 with higher levels of expression in brain metastases from breast cancer illustrating activation of proteins downstream of receptor tyrosine kinase signaling. (B) Selected signaling end points from Table 2 with higher levels of expression in brain metastases from lung cancers suggesting phosphorylation of downstream proteins in the EGFR signaling pathway.
