FA and estrogen stimulate the expression of FATP1/SLC27A1 (solute carrier family 27 member 1) in TNBC, and FATP1/SLC27A1 expression is higher in the more aggressive MDA-MB-231 cell line,16 suggesting that active uptake of FAs plays an important role in breast cancer progression. The gene discussed is SLC27A1; the disease is breast carcinoma.
