In 1994, Jücker et al. investigated METmRNA expression in myeloid cell lines (HL60, K562, U937) and did not detect any; in primary cells they detected MET mRNA for only 6/73 (8%) patients with haematological malignancy: 1 AML, 4 Hodgkin’s lymphoma, 1 Burkitt’s lymphoma (and none of 7 CML tested) [125]. The gene discussed is MET; the disease is chronic myelogenous leukemia, BCR-ABL1 positive.
