SLC27A1 and neoplasm: To further explore the mechanism whereby steatosis promotes lipid uptake by tumor, we performed quantitative PCR (qPCR) analysis of fatty acid transporter proteins (FATPs) in Bo1 cells exposed to fatty liver–conditioned medium and found only FATP1, which mediates adipocyte to tumor transport, increased (Figure 4F and Supplemental Figure 5) (15).
