In addition, a decrease in the expression of AXL, a novel receptor tyrosine kinase known to be an essential EMT-induced regulator of breast cancer and regulated by MZF-1 [41–44], was also observed, and the decrease can be reversed by rescuing MZF-1 expression with protease inhibitor (Supplementary Figure S1D). The gene discussed is NTRK1; the disease is breast carcinoma.
