Here we tested the hypothesis that the expression of purinergic receptors, estrogen receptors and other neuroprotective and pro-inflammatory genes differed among CNS regions in healthy mice. Because neurodegenerative diseases vary in incidence by sex and age, we also examined the regional distribution of these genes in male and female mice of four different ages between 21 days and 12 months. We postulated that pro-inflammatory gene expression would be higher in older animals, and lower in young adult females. We found that microglial gene expression differed across the CNS. Estrogen receptor alpha (Esr1) mRNA levels were often lower in microglia from the brainstem/spinal cord than from the cortex, whereas tumor necrosis factor alpha (Tnfα) expression was several times higher. In addition, the regional pattern of gene expression often changed with animal age; for example, no regional differences in P2X7 mRNA levels were detected in 21 day-old animals, but at 7 weeks and older, expression was highest in cerebellar microglia. Lastly, the expression of some genes was sexually dimorphic. In microglia from 12 month-old animals, mRNA levels of inducible nitric oxide synthase, but not Tnfα, were higher in females than males. These data suggest that microglial gene expression is not uniformly more pro-inflammatory in males or older animals. Moreover, microglia from CNS regions in which neuronal damage predominates in neurodegenerative disease do not generally express more pro-inflammatory genes than microglia from regions less frequently affected. This study provides an in-depth assessment of regional-, sex- and age-dependent differences in key microglial transcripts from the healthy mouse CNS.","PeriodicalId":90374,"journal":{"name":"Transcriptomics: open access","volume":"103 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79525081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Overriding this control will cause genomic instability, a hallmark of cancer. \u0000 \u0000The genome is highly vulnerable to damage, especially during DNA replication because chromosome is decondensed and the replication forks are extremely sensitive to DNA damage agents. The eukaryotic replisome, which consists of a large number of replication fork-associated proteins, is essential for the elongation of replication forks during DNA replication. This complex contains DNA polymerases, MCM helicase, single stranded DNA (ssDNA) binding protein RPA, sliding clamp PCNA, Tipin, Timeless, Claspin, And-1, etc. In cells with DNA damage such as replication stress, replication forks are stalled Figure 1. At stalled replication forks, some of replisome components switch their role from facilitating DNA synthesis to inducing activation of DNA replication checkpoint, a signaling transduction pathway that is critical to maintain fork stability and triggers cell cycle arrest.","PeriodicalId":90374,"journal":{"name":"Transcriptomics: open access","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4172/2329-8936.1000e108","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35915668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, over the past several years this view came to be challenged as several studies provided anecdotal as well as global evidence for the contribution of TEs to the regulatory and coding needs of human genes. In this study, we explored the incorporation and epigenetic regulation of coding sequences donated by TEs using gene expression and other ancillary genomics data from two human hematopoietic cell-lines: GM12878 (a lymphoblastoid cell line) and K562 (a Chronic Myelogenous Leukemia cell line). In each cell line, we found several thousand instances of TEs donating coding sequences to human genes. We compared the transcriptome assembly of the RNA sequencing (RNA-Seq) reads with and without the aid of a reference transcriptome and found that the percentage of genes that incorporate TEs in their coding sequences is significantly greater than that obtained from the reference transcriptome assemblies using Refseq and Gencode gene models. We also used histone modifications chromatin immunoprecipitation sequencing (ChIP-Seq) data, Cap Analysis of Gene Expression (CAGE) data and DNAseI Hypersensitivity Site (DHS) data to demonstrate the epigenetic regulation of the TE derived coding sequences. Our results suggest that TEs form a significantly higher percentage of coding sequences than represented in gene annotation databases and these TE derived sequences are epigenetically regulated in accordance with their expression in the two cell types.</p>","PeriodicalId":90374,"journal":{"name":"Transcriptomics: open access","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2013-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4028971/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32369654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
