Cyclic AMP 0-4 hemoglobin subunit gamma 1 Homo sapiens 30-42 16631597-0 2006 cAMP differentially regulates gamma-globin gene expression in erythroleukemic cells and primary erythroblasts through c-Myb expression. Cyclic AMP 0-4 MYB proto-oncogene, transcription factor Homo sapiens 118-123 16631597-1 2006 Our previous studies demonstrated roles of cyclic nucleotides in gamma-globin gene expression. Nucleotides, Cyclic 43-61 hemoglobin subunit gamma 1 Homo sapiens 65-77 16631597-2 2006 We recently found that, upon activation of the cAMP pathway, expression of the gamma-globin gene is inhibited in K562 cells but induced in adult erythroblasts. Cyclic AMP 47-51 hemoglobin subunit gamma 1 Homo sapiens 79-91 16631597-3 2006 Here we show that c-Myb, a proto-oncogene product that plays a role in cell growth and differentiation, is involved in the cAMP-mediated differential regulation of gamma-globin gene expression in K562 cells and primary erythroblasts. Cyclic AMP 123-127 MYB proto-oncogene, transcription factor Homo sapiens 18-23 16631597-3 2006 Here we show that c-Myb, a proto-oncogene product that plays a role in cell growth and differentiation, is involved in the cAMP-mediated differential regulation of gamma-globin gene expression in K562 cells and primary erythroblasts. Cyclic AMP 123-127 hemoglobin subunit gamma 1 Homo sapiens 164-176 16631597-4 2006 Our studies found that c-Myb is expressed at a high level in K562 cells compared to primary erythroblasts, and that c-Myb expression is further increased following the treatment with forskolin, an adenylate cyclase activator. Colforsin 183-192 MYB proto-oncogene, transcription factor Homo sapiens 23-28 16631597-4 2006 Our studies found that c-Myb is expressed at a high level in K562 cells compared to primary erythroblasts, and that c-Myb expression is further increased following the treatment with forskolin, an adenylate cyclase activator. Colforsin 183-192 MYB proto-oncogene, transcription factor Homo sapiens 116-121 16631597-6 2006 Importantly, forskolin-induced erythroid differentiation in K562 cells, as determined by the expression of glycophorins and CD71, suggesting that high-level expression of c-Myb may not be sufficient to inhibit the differentiation of erythroid cells. Colforsin 13-22 transferrin receptor Homo sapiens 124-128 16631597-6 2006 Importantly, forskolin-induced erythroid differentiation in K562 cells, as determined by the expression of glycophorins and CD71, suggesting that high-level expression of c-Myb may not be sufficient to inhibit the differentiation of erythroid cells. Colforsin 13-22 MYB proto-oncogene, transcription factor Homo sapiens 171-176 16631597-8 2006 Together, these results show that the cAMP pathway blocks gamma-globin gene expression in K562 cells by increasing c-Myb expression and c-Myb plays a role in defining the mode of response of the gamma-globin gene to fetal hemoglobin inducers in erythroid cells. Cyclic AMP 38-42 hemoglobin subunit gamma 1 Homo sapiens 58-70 16631597-8 2006 Together, these results show that the cAMP pathway blocks gamma-globin gene expression in K562 cells by increasing c-Myb expression and c-Myb plays a role in defining the mode of response of the gamma-globin gene to fetal hemoglobin inducers in erythroid cells. Cyclic AMP 38-42 MYB proto-oncogene, transcription factor Homo sapiens 115-120 16631597-8 2006 Together, these results show that the cAMP pathway blocks gamma-globin gene expression in K562 cells by increasing c-Myb expression and c-Myb plays a role in defining the mode of response of the gamma-globin gene to fetal hemoglobin inducers in erythroid cells.
