Positive and negative regulation of the erythropoietin gene.
In order to investigate positive and negative regulatory elements of the erythropoietin (Epo) gene, synthetic oligonucleotides were designed to control Epo transcription by means of an antigen strategy. We devised a new method for detecting regulatory elements of genes that have a weak promoter. Synthetic oligonucleotides were incubated with Hep3B cells in the presence or absence of CoCl2 or hy...

Regulation of the erythropoietin gene.
Erythropoietin (Epo), the hormone that stimulates red blood cell production, is induced by hypoxia. We have utilized the human hepatoma cell line, Hep3B, to investigate the regulation of the Epo gene. We present evidence that the oxygen sensor in Hep3B cells is a heme protein. Hypoxic and cobalt induction of Epo protein is paralleled by a 50- to 100-fold increase in Epo mRNA which we have accur...
