DNA methylation in follicular lymphoma [PDF]

open access: yes, 2010
PhDFollicular Lymphoma (FL) is a common B cell Non-Hodgkin Lymphoma with a median survival of 8-10 years. Patients frequently undergo transformation to a more aggressive lymphoma and this is associated with drastically reduced survival.

Intergenic, gene terminal, and intragenic CpG islands in the human genome

open access: yesBMC Genomics, 2010
Background Recently, it has been discovered that the human genome contains many transcription start sites for non-coding RNA. Regulatory regions related to transcription of this non-coding RNAs are poorly studied.

CpG islands – ‘A rough guide’ [PDF]

open access: yesFEBS Letters, 2009
Mammalian genomes are punctuated by DNA sequences containing an atypically high frequency of CpG sites termed CpG islands (CGIs). CGIs generally lack DNA methylation and associate with the majority of annotated gene promoters. Many studies, however, have identified examples of CGI methylation in malignant cells, leading to improper gene silencing.

Putative zinc finger protein binding sites are over-represented in the boundaries of methylation-resistant CpG islands in the human genome.

open access: yesPLoS ONE, 2007
BackgroundMajority of CpG dinucleotides in mammalian genomes tend to undergo DNA methylation, but most CpG islands are resistant to such epigenetic modification. Understanding about mechanisms that may lead to the methylation resistance of CpG islands is

Linking the epigenome to the genome: correlation of different features to DNA methylation of CpG islands. [PDF]

open access: yesPLoS ONE, 2012
DNA methylation of CpG islands plays a crucial role in the regulation of gene expression. More than half of all human promoters contain CpG islands with a tissue-specific methylation pattern in differentiated cells.

CpG islands and the regulation of transcription [PDF]

open access: yesGenes & Development, 2011
Vertebrate CpG islands (CGIs) are short interspersed DNA sequences that deviate significantly from the average genomic pattern by being GC-rich, CpG-rich, and predominantly nonmethylated. Most, perhaps all, CGIs are sites of transcription initiation, including thousands that are remote from currently annotated promoters.

Prediction of CpG-island function: CpG clustering vs. sliding-window methods

open access: yesBMC Genomics, 2010
Background Unmethylated stretches of CpG dinucleotides (CpG islands) are an outstanding property of mammal genomes. Conventionally, these regions are detected by sliding window approaches using %G + C, CpG observed/expected ratio and length thresholds as

Evolution of CpG-islands by means of tandem duplications

open access: yesВавиловский журнал генетики и селекции, 2017
CG-rich islands (CpG-islands, or CGI) are important functional elements in a genome of vertebrates. In particular, they: a) initiate transcription as promoters in most (> 50 %) genes of vertebrates, in some cases bi-directional, due to self-complement

Nucleosomes correlate with in vivo progression pattern of de novo methylation of p16 CpG islands in human gastric carcinogenesis. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: The exact relationship between nucleosome positioning and methylation of CpG islands in human pathogenesis is unknown. METHODOLOGY/PRINCIPAL FINDINGS: In the present study, we characterized the nucleosome position within the p16 CpG island ...
