Conversely, we observed increased expression of fatty acid transport genes in KRMEFs compared with KMEFs, including Fabp3, Fabp7, and Fabp4, the latter of which has been implicated in progression and metastasis of ovarian cancer (Supplemental Fig. S2E; Nieman et al. 2011; Bensaad et al. 2014). The gene discussed is FABP4; the disease is ovarian carcinoma.
