The present invention relates to a method aiding in the assessment of cancer. It discloses the use of the proapoptotic caspase adaptor protein (=PACAP) as a universal marker of different types of cancer. PACAP aids in the assessment of pulmonary or lung cancer (LC), particularly of non-small cell lung carcinoma (NSCLC), but also of other specific types of cancer. Such specific types of cancer are e.g. colon, bladder, cervix, ovary, endometrial, head and neck, breast, melanoma, pancreas, kidney, prostate, esophagus, stomach or bile duct cancer. Furthermore, the present invention especially relates to a method for assessing cancer from a liquid sample, derived from an individual by measuring PACAP in said sample. Measurement of PACAP can, e.g., be used in the early detection of cancer or in the surveillance of patients who undergo surgery.

Autotaxin (ATX) is a prometastatic enzyme initially isolated from the conditioned media of human melanoma cells that stimulates a myriad of biological activities including angiogenesis and the promotion of cell growth, survival, and differentiation through the production of lysophosphatidic acid (LPA). ATX increases the aggressiveness and invasiveness of transformed cells, and ATX levels directly correlate with tumor stage and grade in several human malignancies. To study the role of ATX in the pathogenesis of malignant melanoma, we developed antibodies and small molecule inhibitors against recombinant human protein. Immunohistochemistry of paraffin embedded human tissue demonstrates that ATX levels are markedly increased in human primary and metastatic melanoma relative to benign nevi. Chemical screens identified several small molecule inhibitors with binding constants ranging from nanomolar to low micromolar. Cell migration and invasion assays with melanoma cell lines demonstrate that ATX markedly stimulates melanoma cell migration and invasion, an effect suppressed by ATX inhibitors. The migratory phenotype can be rescued by the addition of ATX's enzymatic product, LPA, confirming that the observed inhibition is linked to suppression of LPA production by ATX. Chemical analogues of the inhibitors demonstrate structure activity relationships important for ATX inhibition and indicate pathways for their optimization. These studies suggest that ATX is an approachable molecular target for the rational design of chemotherapeutic agents directed against human malignancies driven by the ATX/LPA axis, especially including malignant melanoma, among numerous others including breast and ovarian cancers.
