Human leukemic cells contain transforming growth factor. 1983

H Nakamura, and K Komatsu, and H Akedo, and M Hosokawa, and H Shibata, and T Masaoka

A transforming growth factor was found in the extracts of leukemic cells obtained from the peripheral blood of 11 patients with leukemia. This factor stimulated the colony formation of anchorage-dependent BALB/c 3T3 cells in soft agar. The high levels of colony-stimulating activities were observed in the cell extracts from patients with chronic myelogenous leukemia in blastic crisis (CML BC), acute myelogenous leukemia and CML in chronic phase. The factor from a CML BC patient was heat- and acid-labile, relatively stable to dithiothreitol treatment and inactivated by pronase treatment. Molecular size of the factor seems more than 10,000 daltons.

UI MeSH Term Description Entries
D007938 Leukemia A progressive, malignant disease of the blood-forming organs, characterized by distorted proliferation and development of leukocytes and their precursors in the blood and bone marrow. Leukemias were originally termed acute or chronic based on life expectancy but now are classified according to cellular maturity. Acute leukemias consist of predominately immature cells; chronic leukemias are composed of more mature cells. (From The Merck Manual, 2006) Leucocythaemia,Leucocythemia,Leucocythaemias,Leucocythemias,Leukemias
D007962 Leukocytes White blood cells. These include granular leukocytes (BASOPHILS; EOSINOPHILS; and NEUTROPHILS) as well as non-granular leukocytes (LYMPHOCYTES and MONOCYTES).

D008970 Molecular Weight The sum of the weight of all the atoms in a molecule. Molecular Weights,Weight, Molecular,Weights, Molecular
D010455 Peptides Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are considered to be larger versions of peptides that can form into complex structures such as ENZYMES and RECEPTORS. Peptide,Polypeptide,Polypeptides
