![Stress induces expression of genes subject to miRNA-mediated regulation. (A) The x -axis shows differential expression (log 2 ) between mock transfected and untransfected cultures, the y -axis shows the adjusted P -value ( − log 10 ) for differential expression. Each point on the plot uniquely represents one gene, genes above the dashed line are differentially expressed with multiple testing adjusted P < 0.1. The insets show enrichment (log 2 ) of genes either downregulated (white bars) or induced (black bars) by stressful treatments. Genes differentially expressed upon KCl treatment where identified by Illumina microarrays (Materials and Methods). Genes differentially expressed upon kainite treatment where derived from published <t>microarray</t> profiling data (Akahoshi et al., ; Materials and Methods). Mouse homologs (from HomoloGene; Sayers et al., ) of human genes that were previously reported as differentially expressed upon aging of the human brain comprised the aging sets. Double asterisks indicate hypergeometric P < 0.001 (Materials and Methods). The set of 10,849 genes detected by Illumina microarrays (Materials and Methods) in mock transfected and untransfected cultures was used as the universe for the hypergeometric tests. (B) The x -axis represents 3′UTRs corresponding to expressed genes sorted from most downregulated to most upregulated in comparison of mock transfected vs. untransfected cultures. P -values are calculated using the Sylamer method (van Dongen et al., ). Positive values on the y -axes represent nucleotide word enrichment [+|log 10 ( P -value)|] and negative values represent depletion [−|log 10 ( P -value)|]. The red and blue lines show enrichment profiles of 7(2) or 7(1A)-type seed matching sites (Bartel, ) for miR-124, the gray lines – for other miRNAs (Materials and Methods).](https://pub-med-central-images-cdn.bioz.com/pub_med_central_ids_ending_with_3788/pmc03483788/pmc03483788__fnins-06-00156-g001.jpg)

Figure Legend Snippet: Comparison with previously published miR-124 targets . (A,B) The Venn diagrams show counts of putative direct targets of miR-124 that were inferred from the transfection experiments in this work and from the published HITS-CLIP sequencing (Chi et al., ) and microarray (Lim et al., ) experiments. The latter study is based on HeLa transfrection experiment. The mouse homologs of human miR-124 targets were retrieved from HomoloGene http://www.ncbi.nlm.nih.gov/homologene ; (C) the Venn diagram shows counts of miR-124 targets reported in HeLa study (Lim et al., ) and transcripts induced by transfection alone in our experiment. In all cases the test universe was 3,465 mouse transcripts, with 3′UTRs containing one or more 7(2) or 7(1A)-type seed matching site for miR-124. The test universe was a complete list of mouse genes encoding transcripts with 3′UTRs containing one or more 7(2) or 7(1A)-type seed matching site for miR-124, and which were represented on Illumina Sentrix BeadChip Array Mouse-WG6 v2 microarray platform (3,465 genes in total). The text shows fold enrichment above what is expected by chance alone and the hypergeometric P -value for the intersection.

Article Snippet: Physiological ageing and tumorigenesis are both associated with epigenomic alterations in human tissue cells, the most extensively investigated of which entails de novo cytosine methylation (i.e., hypermethylation) within the CpG dinucleotides of CpG islands.. Genomic regions that become hypermethylated during tumorigenesis are generally believed to overlap regions that acquire methylation in normal tissues as an effect of ageing.. To define the extension of this overlap, we analysed the DNA methylomes of 48 large-bowel tissue samples taken from women of different ages during screening colonoscopy: 18 paired samples of normal and lesional tissues from donors harbouring a precancerous lesion and 12 samples of normal mucosa from tumourfree donors.
