RTN4 and neoplasm: Human protein array analyses identified cellular targets of XON9, such as solute carrier family 3 member 2 (SLC3A2), annexin A5 (ANXA5), fatty acid synthase (FASN) or reticulon 4 (RTN4) involved notably in tumor progression, angiogenesis, cell growth or apoptosis (Supplementary Table S1 [28,29,30,31,32]).
