Establishment of three permanent human leukaemia cell lines producing immunoreactive calcitonin. 1987

H Koeppler, and K H Pflueger, and W Knapp, and K Havemann

Three permanent human leukaemia cell lines, designated EW2, LG3 and MS6, were established from bone marrow aspirates of a patient with acute myelomonocytic leukaemia (EW2), acute monocytic leukaemia (LG3) and acute myeloblastic leukaemia (MS 6). In vitro all lines exhibited a myelomonocytoid marker profile in terms of classical staining reactions and cell-surface antigen structure. In supernatants and extracts of EW2 and MS 6 cells immunoreactive human calcitonin was found in raised levels. No significant levels of immunoreactive human calcitonin were found in supernatants of LG3 cells, while extracts of LG3 cells and the patients sera at diagnosis contained high levels, suggesting the in vitro selection of a non-secreting clone of leukaemic cells. Gel-chromatography showed several peaks of ihCT with higher molecular weight than normal human calcitonin, suggesting the production of precursor molecules. In addition to ihCT raised levels of immunoreactive calcitonin gene related peptide (ICGRP) was found in supernatants of EW2. These data support the concept of ectopic immunoreactive human calcitonin production by leukaemic cells.

D007948	Leukemia, Monocytic, Acute	An acute myeloid leukemia in which 80% or more of the leukemic cells are of monocytic lineage including monoblasts, promonocytes, and MONOCYTES.

D009363	Neoplasm Proteins	Proteins whose abnormal expression (gain or loss) are associated with the development, growth, or progression of NEOPLASMS. Some neoplasm proteins are tumor antigens (ANTIGENS, NEOPLASM), i.e. they induce an immune reaction to their tumor. Many neoplasm proteins have been characterized and are used as tumor markers (BIOMARKERS, TUMOR) when they are detectable in cells and body fluids as monitors for the presence or growth of tumors. Abnormal expression of ONCOGENE PROTEINS is involved in neoplastic transformation, whereas the loss of expression of TUMOR SUPPRESSOR PROTEINS is involved with the loss of growth control and progression of the neoplasm.	Proteins, Neoplasm
D002116	Calcitonin	A peptide hormone that lowers calcium concentration in the blood. In humans, it is released by thyroid cells and acts to decrease the formation and absorptive activity of osteoclasts. Its role in regulating plasma calcium is much greater in children and in certain diseases than in normal adults.
