Several of the identified genes have previously been involved in cancer drug resistance (Glutathione S-transferase Pi 1 (GSTP1)), remodeling of tissue (matrix remodeling associated 7 (MXRA7)), or interaction with extracellular matrix (the collagen receptor Leukocyte-Associated Immunoglobin-Like Receptor 2 (LAIR2)) [32]. This evidence concerns the gene GSTP1 and cancer.
