Embryonic-fetal erythroid characteristics of a human leukemic cell line.
We have studied a number of cell surface, enzyme, and protein markers in the human leukemic K562 cell line. We have confirmed previous observations that these cells accumulate human embryonic hemoglobins after exposure to hemin. In addition, our results demonstrated that these cells possess in the "ininduced" state i surface antigen, lactate dehydrogenase isoenzymes characteristic of embryonic ...
متن کاملEmbryonic erythroid differentiation in the human leukemic cell line K562.
K562 human leukemia cells synthesize embryonic hemoglobins after culture in the presence of hemin. We have rigorously identified these hemoglobins by globin chain analysis and peptide mapping. No adult hemoglobin could be detected, and beta-globin synthesis was less than 2 ppm of total protein synthesis. Persistent embryonic globin gene expression is known to occur as a consequence of globin ge...
متن کاملGrowth and Isolation of Human Cytomegalovirus on a New Human Fetal Foreskin Fibroblast-derived Cell Line in Iran
Cell culture technique has been used for detection and confirmation of many different viruses in clinical samples. Although, new diagnostic methods have been developed for viral infections, traditional cell culturetechnique is still regarded as the “gold standard” for several infectious agents such as human cytomegalovirus(HCMV). In the present study, a new human fetal foreskin fibr...
متن کاملOverexpression of microRNA-630 in Acute Leukemic T-cell line
Background: MicroRNAs (miRNAs) are noncoding RNAs that control the expression of their target mRNAs. It affects cancer cell proliferation and apoptosis as oncogenes or tumor suppressors. Dysregulation of miRNAs expression leads to the development of various cancers. Therefore, for the first time in this field, this study investigated the effect of overexpression of microRNA-630 on the Jurkat ce...
متن کاملMetabolism of proline in a human leukemic lymphoblastoid cell line.
Amino acid analysis of the culture medium was carried out in a human leukemic lymphoblastoid cell line (REH) established from the lymphoblasts of a patient with acute lymphoid leukemia. The results are compared with those of a reference cell line (LHN13) established from normal human lymphocytes. The most striking difference between these two cell lines concerns proline. In LHN13 the concentrat...
