The cell lines exhibiting the strongest co-expression of ADAM9, TNFRSF12A, and AXL were 2 ovarian cancer lines (OVCAR_8 and SK_OV_3), lung cancer line HOP_92, and several renal cancer lines, suggesting that these cell lines may be particularly active in degrading extracellular matrix. The gene discussed is ADAM9; the disease is ovarian carcinoma.
