Increased rate of degradation of c-myc mRNA in interferon-treated Daudi cells.

Increased rate of degradation of c-myc mRNA in interferon-treated Daudi cells.

The recent observation made in our laboratory that cellular myc (c-myc) mRNA has a very short half-life in a variety of normal and transformed human cells emphasized the potential importance of post-transcriptional regulation of c-myc gene expression. Jonak and Knight [Jonak, G. J. & Knight, E., Jr. (1984) Proc. Natl. Acad. Sci. USA 81, 1747-1750] have reported a selective reduction of c-myc mR...

Interferon - a Down - regulates Insulin Receptors in Lymphoblastoid ( Daudi ) Cells

The Daudi line of human lymphoblastoid cells requires insulin and transferrin for growth in serumfree medium and is highly sensitive to the inhibitory effect of human leukocyte interferon (IFN-a) on cell proliferation. A variant subline of Daudi cells, which is resistant to the antiproliferative action of IFN-a, also has been grown in serum-free medium containing insulin and transferrin. The pr...

cloning of c-myc gene in embryonic stem cells

embryonic stem cells (escs) are pluripotent, self-renewing cells. these cells can be used in applications such as cell therapy, drug discovery, disease modelling, and the study of cellular differentiation. in this experimental study embryonic stem cells cultured in the laboratory and were amplified. total rna was extracted from cells and converted to cdna by reverse transcription-polymerase cha...
