FCM在横纹肌肉瘤细胞周期和DNA倍体分析研究中的应用
流式细胞术 横纹肌肉瘤 DNA倍体
2009/3/25
目的:以20年来的病理资料存档完整的90例横纹肌肉瘤石蜡标本为研究对象,研究横纹肌肉瘤细胞的细胞周期和DNA倍体变化与临床病理分型之间的相关性。方法:荧光染料使用碘化丙啶(PI),PI可以和DNA双链结合,细胞中PI染料的含量与DNA的含量成正比,因此PI的含量就间接反映出细胞中DNA的含量和周期分布情况。结果:二倍体8例(8/90 8.89%),次二倍体4例(4/90 4.44%),超二倍体38...
Copper Binding of Nuclear RNA- and DNA-Binding Proteins p54nrb/NonO and PSF
copper p54nrb/Non-POU-domain-containing octamer binding protein (p54nrb/NonO) polypyrimidine tract-binding protein-associated splicing factor (PSF) nucleus
2009/3/23
The biological function of nuclear copper in mammalian cells is poorly understood because little is known about specific binding protein(s) for nuclear copper. We recently purified that p54nrb/Non-POU...
Mechanisms of the DNA Damage in Rat Kidney after Au Injection
Gold (Au) Copper (Cu) 8-hydroxydeoxyguanosine (8-OHdG) DNA damage Metallothionein (MT)
2009/3/16
Au (gold) is a heavy metal and its complexes are one of the more effective medicaments available for rheumatoid arthritis, although many authors have reported serious kidney damage during the chrysoth...
Brca2 C-terminus interacts with Rad51 and contributes to nuclear focus formation in double-strand break repair of DNA
Brca2 C-terminus interacts Rad51 double-strand break repair of DNA
2009/3/3
In humans and mice, the interaction between the breast cancer susceptibility protein, BRCA2, and RAD51 recombinase is essential for DNA repair by homologous recombination, the failure of this process ...
Evidence for inclusion of a segment of Escherichia coli genomic DNA in bovine tooth germ mRNA encoding salivary proline-rich protein P-B
Escherichia coli genomic DNA germ mRNA salivary proline-rich protein P-B
2009/3/3
In the course of cloning of bovine cDNA for proline-rich protein (PRP) P-B from bovine tooth germ cDNA, we found that one clone with 662 bp contained a 5'-terminal 393 bp (1-393 bp) sequence essenti...
DNA microarray analysis of changes in gene expression induced by 1,25-dihydroxyvitamin D3 in human promyelocytic leukemia HL-60 cells
DNA microarray analysis gene expression 1,25-dihydroxyvitamin D3 promyelocytic leukemia HL-60 cells
2009/3/2
Using a DNA microarray, we analyzed about 16,600 genes for changes in expression associated with the differentiation of human promyelocytic leukemia HL-60 cells induced by 1α,25-dihydroxyvitamin D3 ...
Extremely narrow nanopores developed in Professor Amit Meller’s laboratory (BME) may be just the tool scientists need to reach the goal of a fast and inexpensive method of sequencing entire genomes.Re...
