We recently found that inhibition of MYB protein synthesis in human peripheral blood mononuclear cells (PBMC) exposed to human c-myb (designated MYB) antisense oligodeoxynucleotides prevents entry into S phase and cell proliferation. To determine the mechanism(s) by which down-regulation of human c-myb protein (MYB) synthesis interferes with DNA synthesis, we analyzed mRNA levels of DNA polymer...
MYB proteins comprise a large family of plant transcription factors, members of which perform a variety of functions in plant biological processes. To date, no genome-wide characterization of this gene family has been conducted in maize (Zea mays). In the present study, we performed a comprehensive computational analysis, to yield a complete overview of the R2R3-MYB gene family in maize, includ...
The involvement of the transcription factor c-Myb in promoting the proliferation and inhibition of erythroid cell differentiation has been established in leukemia cell models. The anemia phenotype observed in c-myb knockout and knockdown mice highlights a critical role for c-Myb in erythropoiesis. However, determining the reason for the failure of erythropoiesis in these mice and the precise fu...
An alternatively spliced form of c-myb exists that encodes an additional 120 amino acids in chicken and 121 amino acids in human and mouse. These amino acids are encoded by an additional exon, termed exon 9A. This exon is not present in v-myb, and proteins containing these amino acids have never been tested for oncogenic transformation. A series of myb constructs was therefore created in order ...
The proteins of the MYB superfamily play central roles in developmental processes and defence responses in plants. Sixty unique wheat MYB genes that contain full-length cDNA sequences were isolated. These 60 genes were grouped into three categories, namely one R1R2R3-MYB, 22 R2R3-MYBs, and 37 MYB-related members. The sequence composition of the R2 and R3 repeats was conserved among the 22 wheat...
MYB transcription factor is the largest family of factors in plants, and they are involved regulation plant growth development, secondary metabolism, adversity stress other biological processes. So far, there no study on of Rhododendron lapponicum . In this study, the variety ‘Fuli Jinling’ transcriptome was generated by SMRT sequencing technology. A total 15....
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...
The c-Myb gene encodes a transcription factor required for proliferation and survival of normal myeloid progenitors and leukemic blast cells. Targeting of c-Myb by antisense oligodeoxynucleotides has suggested that myeloid leukemia blasts (including chronic myelogenous leukemia [CML]-blast crisis cells) rely on c-Myb expression more than normal progenitors, but a genetic approach to assess the ...
We investigated the role of B-Myb, a cell-cycle-regulated transcription factor, in the expression of the alpha1 (I) pro-collagen gene (COL1A1) in scleroderma fibroblasts. Scleroderma or SSc (systemic sclerosis) is a fibrotic disease characterized by excessive production of extracellular matrix components, especially type I collagen. Northern-blot analysis showed an inverse relationship between ...
BACKGROUND The transcription factor B-Myb is present in all proliferating cells, and in mice engineered to remove this gene, embryos die in utero just after implantation due to inner cell mass defects. This lethal phenotype has generally been attributed to a proliferation defect in the cell cycle phase of G1. METHODOLOGY/PRINCIPAL FINDINGS In the present study, we show that the major cell cyc...
