The TAM‐selective expression of autotaxin and PLA2G7 and the cell type‐independent high expression of PLA2G12A were confirmed analyzing the secretome of patient‐derived tumor cells, TAMs, and TATs in short‐term cultures (conditioned medium) by LC‐MS/MS‐based proteomics (Fig. 1C). This evidence concerns the gene ENPP2 and neoplasm.
