Title: Expression of the heparin-binding growth factor receptor genes in human megakaryocytic leukemia cells. Author: Katoh O, Hattori Y, Sato T, Kimura A, Kuramoto A, Sugimura T, Terada M. Journal: Biochem Biophys Res Commun; 1992 Feb 28; 183(1):83-92. PubMed ID: 1311927. Abstract: K-sam/bek, N-sam/flg and FGFR3/sam3 establish gene family of the receptors for heparin-binding growth factors (HBGFs) or FGFs. These mRNAs were detected in human leukemia cells, CMK, K562 and HEL, which have megakaryocytic phenotype or the potency to differentiate into megakaryocytic lineage. In CMK cells N-sam/flg transcript level was enhanced by the culture with 12-O-tetradecanoylphorbol-13-acetate (TPA). cDNA-polymerase chain reaction identified K-sam/bek mRNA in human platelets, suggesting the involvement of HBGFs in megakaryocytopoiesis and functions of platelets.[Abstract] [Full Text] [Related] [New Search]
