Chromosome-specific DNA repeat probes.
In research as well as in clinical applications, fluorescence in situ hybridization (FISH) has gained increasing popularity as a highly sensitive technique to study cytogenetic changes. Today, hundreds of commercially available DNA probes serve the basic needs of the biomedical research community. Widespread applications, however, are often limited by the lack of appropriately labeled, specific...
متن کاملMitosis-specific phosphorylation of the nuclear oncoproteins Myc and Myb
The c-myc and c-myb proto-oncogenes encode phosphorylated nuclear DNA binding proteins that are likely to be involved in transcriptional regulation. Here we demonstrate that both Myc and Myb proteins are hyperphosphorylated during mitosis. In the case of Myb, hyperphosphorylation is accompanied by the appearance of three M phase-specific tryptic phosphopeptides. At least one of these phosphopep...
متن کاملSequence specific sensitivity of oligonucleotide probes
Gene expression analysis by means of high-density-oligonucleotide-array chips is based on the sequence specific binding of mRNA to oligonucleotide probes and its measurement using fluorescence labels. The sensitivity of a probe to detect a certain amount of target mRNA considerably varies among the about 400.000 probes, which are covalently attached to a typical Affymetrix chip. We present a mo...
متن کاملCyclin A1 directly interacts with B-myb and cyclin A1/cdk2 phosphorylate B-myb at functionally important serine and threonine residues: tissue-specific regulation of B-myb function.
Cyclin A1 is tissue-specifically expressed during spermatogenesis, but it is also highly expressed in acute myeloid leukemia (AML). Its pathogenetic role in AML and in the cell cycle of leukemic blasts is unknown. B-myb is essential for G1/S transition and has been shown to be phosphorylated by the cyclin A2/cdk2 complex. Here it is demonstrated that cyclin A1 interacts with the C-terminal port...
متن کاملc-Myb-induced trans-activation mediated by heat shock elements without sequence-specific DNA binding of c-Myb.
The c-myb proto-oncogene product (c-Myb) can transactivate the human hsp70 promoter in a transient cotransfection assay. The present studies have demonstrated that the heat shock element (HSE) in the hsp70 promoter mediates trans-activation by c-Myb. Mutagenesis of the DNA sequence in HSE indicated that the NGAAN motif is necessary for not only the heat shock response but also the c-Myb-induced...
