LEP and breast carcinoma: Using two murine models of metastatic triple-negative breast cancer (TNBC) differing in genetic alterations (4T1: p53 and Pik3ca mutations; metM-Wntlung: increased Wnt signaling) and cultured in physiological (5 mM) glucose media, we tested the hypothesis that leptin increases migration of metastatic breast cancer cells through regulation of glucose metabolism.
