Identification and Validation of Candidate Radiation-responsive Genes for Human Biodosimetr.

چکیده
The aim of the present study is to analyze the global research trend of radiation-responsive genes and identify the highly reproducible radiation-responsive genes. Bibliometric methods were applied to analyze the global research trend of radiation-responsive genes. We found 79 publications on radiation-responsive genes from 2000 to 2017. A total of 35 highly reproducible radiation-responsive genes were identified. Most genes are involved in response to DNA damage, cell proliferation, cell cycle regulation, and DNA repair. The p53 signal pathway was the top enriched pathway. The expression levels of 18 genes in human B lymphoblastoid cell line (AHH-1) cells were significantly up-regulated in a dose-dependent manner at 24 h after exposure to 0-5 Gy 60Co γ-ray irradiation. Our results indicate that developing a gene expression panel with the 35 high reproducibility radiation-responsive genes may be necessary for qualitative and quantitative assessment after exposure.

Genomic Profiling of a Human Leukemic Monocytic Cell-Line (THP-1) Exposed to Alpha Particle Radiation
This study examined alpha (α-) particle radiation effects on global changes in gene expression in human leukemic monocytic cells (THP-1) for the purposes of mining for candidate biomarkers that could be used for the development of a biological assessment tool. THP-1 cells were exposed to α-particle radiation at a dose range of 0 to 1.5 Gy. Twenty-four hours and three days after exposure gene ex...

AbstractTwo Arabidopsis thaliana genes, psr9.2 and psr9.4 appearedto be highly similar to a phosphate-starved induced gene,psr9, isolated from Brassica nigra suspension cells.Sequence analysis classified the encoded polypeptides asmembers of leucine-rich repeat (LRR) proteins superfamily.The sequence of psr9 proteins comprise a unique N-terminalregion e...
متن کاملGenome-wide identification of CBX2 targets: insights in the human sex development network.
Chromobox homolog 2 (CBX2) is a chromatin modifier that plays an important role in sexual development and its disorders (disorders of sex development [DSD]), yet the exact rank and function of human CBX2 in this pathway remains unclear. Here, we performed large-scale mapping and analysis of in vivo target loci of the protein CBX2 in Sertoli-like NT-2D1 cells, using the DNA adenine methyltransfe...
متن کاملValidation of a genus-specific gene; TPS, used as internal control in quantitative Real Time PCR of transgenic cotton
Identification of genes with invariant levels of gene expression is a prerequisite for validating transcriptomic changes accompanying development. Ideally expression of these genes should be independent of the morphogenetic process or environmental condition.We report here the validation of internal control gene i.e.TPS (trehalose 6-phosphate-synthase) in cotton (Gossypium spp), using TaqMan sy...
متن کاملIdentification of cold-responsive genes in a New Zealand alpine stick insect using RNA-Seq.
The endemic New Zealand alpine stick insect Micrarchus nov. sp. 2 regularly experiences sub-zero temperatures in the wild. 454-based RNA-Seq was used to generate a de novo transcriptome and differentiate between treatments to investigate the genetic basis of cold tolerance. Non cold-treated individuals were compared to those exposed to 0°C for 1 h followed by a 1 h recovery period at 20°C. We a...
