Organic cation/carnitine transporter 2 (OCTN2) is a member of the solute carrier superfamily which facilitates oxaliplatin uptake in cancer cells, while peroxisome proliferator-activated receptor γ (PPARγ) binds to the PPAR-response element within the first intron of the OCTN2 gene [220,221]. Here, SLC22A5 is linked to cancer.
