Among them are genes involved in cell adhesion/migration processes (PEPD), migratory potential of cancer cells (ACTN1), ECM (LTBP2, PRG4, ADGRL1, CD9), or in metabolic processes (LDHD, ALDH7A1), as well as proto-oncogenes or their ligands/inhibitors (FYN, PPP1R13L). This evidence concerns the gene PRG4 and cancer.
