The A-Myb transcription factor is structurally related to the c-myb proto-oncogene and is involved in the control of proliferation and/or differentiation of mature B lymphocytes. We have shown previously by PCR analysis that A-myb is preferentially expressed in CD38+ CD39- sIgM- mature B cells. We demonstrate here, using in situ hybridization, that A-myb expression is restricted to the dark zon...

Limitless cell proliferation, evasion from apoptosis, dedifferentiation, metastatic spread and therapy resistance: all these properties of a cancer cell contribute to its malignant phenotype and affect patient outcome. MYBL2 (alias B-Myb) is a transcription factor of the MYB transcription factor family and a physiological regulator of cell cycle progression, cell survival and cell differentiati...

Drought stress has been one of the serious constraints affecting chickpea productivity to a great extent. Genomics-assisted breeding has a potential to accelerate breeding precisely and efficiently. In order to do so, understanding the molecular mechanisms for drought tolerance and identification of candidate genes are crucial. Transcription factors (TFs) have important roles in the regulation ...

The transcription factors of the Myb family are expressed in several tissues and play an important role in cell proliferation, differentiation, and survival In this study, the expression of A-myb, B-myb, and c-myb was investigated in a group of 64 neuroblastomas at different dinical stages by a sensitive reverse transcription-PCR tchnique and correlated with patients' survival. All of the myb g...

The KIX domain of CBP is a transcriptional coactivator. Concomitant binding to the activation domain of proto-oncogene protein c-Myb and the transactivation domain of the trithorax group protein mixed lineage leukemia (MLL) transcription factor lead to the biologically active ternary MLL∶KIX∶c-Myb complex which plays a role in Pol II-mediated transcription. The binding of the activation domain ...

BACKGROUND Esophageal adenocarcinoma develops through a multistage process which is characterized histopathologically by progression from Barrett's intestinal metaplasia to Barrett's esophagus with dysplasia and ultimately to adenocarcinoma. The genetic basis of this process is increasingly well understood, but no studies have examined the role of the transcription factor c-myb in this disease....

The transcription factors of the Myb family are expressed in several tissues and play an important role in cell proliferation, differentiation, and survival. In this study, the expression of A-myb, B-myb, and c-myb was investigated in a group of 64 neuroblastomas at different clinical stages by a sensitive reverse transcription-PCR technique and correlated with patients’ survival. All of the my...

1 Kanagawa Academy of Science and tion assays, and atomic force microscopy confirmed that the interaction of c-Myb and C/EBP␤ observed in Technology (KAST) 3-9 Fukuura crystal mimics their long range interaction on the promoter , which is accompanied by intervening DNA Kanazawa-ku Yokohama 236-0004 looping. Japan Japan the DNA into sufficiently close proximity to enable them 8 Protein Dynamics ...

The key haematopoietic regulator Myb is essential for coordinating proliferation and differentiation. ChIP-Sequencing and Chromosome Conformation Capture (3C)-Sequencing were used to characterize the structural and protein-binding dynamics of the Myb locus during erythroid differentiation. In proliferating cells expressing Myb, enhancers within the Myb-Hbs1l intergenic region were shown to form...
