Structure and properties of human interferon-alpha from Namalwa lymphoblastoid cells.
The chromatographic properties of human interferon-alpha from Namalwa lymphoblastoid cells on Sephadex G-75 are described. The interferons are separated into two groups of four, with apparent molecular weights 19050 and 22000. Some of the latter form dimers at high concentrations. Fractions containing interferon were studied by polyacrylamide-gel electrophoresis in the presence of sodium dodecy...
متن کاملInhibition of transferrin receptor expression by interferon-alpha in human lymphoblastoid cells and mitogen-induced lymphocytes.
125I-Transferrin binding to lymphoblastoid K562 and Daudi cells markedly increased after exposure of the cells to culture conditions that stimulated proliferation. Treatment of these cells with interferon-alpha (IFN-alpha) resulted in concurrent inhibition of cell growth and of the rise in transferrin binding. Scatchard analyses revealed that IFN reduced the number of transferrin receptors with...
متن کاملExpression Analysis of Interferon Beta Level in HEK293T Cells Using Real-Time PCR and Protein Tests
Background: Interferons are some kind of natural cytokines which express in response to a variety of antigens including viral RNA, bacterial products, and tumor proteins. Interferon beta is used in the treatment of autoimmune diseases such as multiple sclerosis. Moreover, this drug inhibits cellular proliferation as well as angiogenesis and as a result, helps to cure cancer. In this research, i...
متن کاملInterferon-induced gene expression in wild-type and interferon-resistant human lymphoblastoid (Daudi) cells.
Interferon-induced gene expression was analyzed in wild-type and interferon-resistant Daudi cells. Two classes of alpha-interferon-induced mRNAs and proteins were observed: those that were similarly induced in both types of cell and those that were induced only in the wild-type cells. Furthermore, the level of c-myc mRNA decreased in the wild-type but not in the resistant cells. This differenti...
متن کاملMultiple human beta interferon genes
Analysis of human beta interferon (IFN) mRNA preparations obtained from poly(I) . poly (C)-induced human diploid fibroblasts (FS-4) and from several similarly induced human-mouse somatic cell hybrids by electrophoresis through agarose-CH3HgOH tube gels led to the detection of at least five translationally active human IFN-beta mRNA species. The results obtained are consistent with the existence...
