(Submitter supplied) Multiple factors, including molecular, genetic, and epigenetic changes, have been linked to gastric cancer formation and progression. Cytosine methylation (5mC) has been well studied and recognized as a critical epigenetic mark in the mammalian genome. The recent novel discovery of 5-hydroxymethylcytosine (5hmC), which generated by ten-eleven translocation (TET) enzymes, provide new perspective to understand DNA methylation-related plasticity. more...

(Submitter supplied) Genome wide gene expression was determined in paired samples of OA affected and preserved cartilage of the same joint using microarray analysis for 33 patients of the RAAK-study. Among the 1717 genes that were significantly different expressed between OA affected and preserved cartilage we found significant enrichment for genes involved in skeletal development (e.g. TNFRSF11B and FRZB). Also several inflammatory genes such as CD55, PTGES and TNFAIP6, previously identified in within-joint analyses as well as in analyses comparing preserved cartilage from OA affected joints versus healthy cartilage were among the top genes. more...

(Submitter supplied) We employed Assay for Transposase-Accessible Chromatin with high throughput sequencing (ATAC-seq) to map the accessible chromatin landscape in articular knee cartilage of OA patients. We identified 109,215 accessible chromatin regions for cartilages, of which 71% were annotated as enhancers. By overlaying them with genetic and DNA methylation data, we have determined potential OA-relevant enhancers and their putative target genes. more...

(Submitter supplied) The aim of this study was to characterise the genome-wide DNA methylation profile of osteoathritis (OA) chondrocytes from both knee and hip cartilage, providing the first comparison of DNA methylation between OA and non-OA hip cartilage, and between OA hip and OA knee cartilage. The study was performed using the Illumina Infinium HumanMethylation450 BeadChip array. Genome-wide methylation was assesed in chondrocyte DNA extracted from 23 OA hip, 73 OA knee and 21 healthy hip controls (NOF - neck of femure samples). more...

(Submitter supplied) 5-hydroxymethylcytosine (5-hmC) is a newly discovered modified form of cytosine that has been suspected to be an important epigenetic modification in neurodevelopment. While DNA methylation dynamics have already been implicated during neurodevelopment, little is known about hydroxymethylation in this process. Here we report DNA hydroxymethylation dynamics during cerebellum development in the human brain. more...

(Submitter supplied) We report an immortalised CRISPR-Cas9 mesenchymal stem cell line knockdown of Plectin, we initally noted that patients with osteoarthritis association single nucelotide polymorphism rs11780978 had a correlation between genotype at rs11780978 and allelic expression imbalance, with a reduced expression of Plectin from the risk allele. We replicated the effect of the risk allele by deleting 26bp from exon 3 of Plectin to generate multiple knockdown lines to assess the molecular phenotype of Plectin knockdown in the cells. more...

(Submitter supplied) Alzheimer's disease (AD) is a chronic neurodegenerative disorder characterized by progressive deterioration of cognitive function. Evidence suggests a role for epigenetic regulation, in particular the cytosine modifications 5-methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC,) in AD. 5hmC is highly enriched in the nervous system and displays neurodevelopment and age-related changes. To determine the role of 5hmC in AD, we performed genome-wide analyses of 5hmC in DNA from prefrontal cortex of post-mortem AD as well as RNA-Seq to correlate changes in methylation status with transcriptional changes. more...

This approach found a genome-wide disruption in 5hmC associated with acute stress response, primarily in genic regions, and identified known and potentially novel stress-related targets that have a significant enrichment for neuronal ontological functions. more...

(Submitter supplied) We generated a genome-wide map of 5hmC in rice panicle using a sensitive chemical labeling method to capture DNA fragments with 5hmC modification, followed by NGS sequencing. We showed that the 5hmC peaks distribution is non-random, about 52% 5hmC was located in gene bodies, 25% in intergenic regions, 11% in promoters, and 12% in immediate downstream. It was significantly enriched in heterochromatic regions of chromosomes 4 and 10, and especially located around TE genes. more...
