1 Triggering differentiation of peripheral blood monocytes, monocytic U-937 or promyelocytic HL-60 precursor cells to macrophage-like cells by phorbol ester treatment transiently induced both a rapid reduction in surface CD4, demonstrated by flow-cytometry analysis, and a gradual loss of CD4 mRNA, revealed by Northern-blot analysis. Phorbol Esters CD4 molecule Homo sapiens

3 Experiments in HL-60 cells to determine the cause of the observed decay in CD4 mRNA levels suggested that the half-life of CD4 transcripts did not diminish but increased after phorbol ester stimulation. Phorbol Esters CD4 molecule Homo sapiens

5 Direct measurement of CD4 gene transcription by run-on analysis indicated that the rate of synthesis of new CD4 mRNA molecules was reduced approximately 10-fold after phorbol ester stimulation, whereas the rate of synthesis of c-fos mRNA resulted in a 2.5-fold increase.
