Bidding the CpG island goodbye

open access: yeseLife, 2013
Experiments on seven vertebrates suggest that identifying the locations of islands of non-methylated DNA provides more insights into evolutionarily-conserved epigenetic regulatory elements than studies of CpG islands.

Analysis of Human Uniparental Embryonic Stem Cells Reveals New Putative Imprinted Loci

open access: yesCell Proliferation, EarlyView.
To identify novel imprinted genes, parthenogenetic, androgenetic and biparental human embryonic stem cells and their differentiated neural progenitors were analysed by methylome and transcriptome profiling. This approach uncovered 12 putative novel imprinted genes, including a clustered region on chromosome 19, expanding the current catalogue of ...

Enrichment analysis of Alu elements with different spatial chromatin proximity in the human genome [PDF]

open access: yes, 2016
Transposable elements (TEs) have no longer been totally considered as “junk DNA” for quite a time since the continual discoveries of their multifunctional roles in eukaryote genomes.

Behind the scenes: how the EMILIN/Multimerin family shapes the cancer landscape

open access: yesThe FEBS Journal, EarlyView.
The EMILIN/Multimerin family members regulate key hallmarks of cancer—including apoptosis, angiogenesis, metastasis, and tumor microenvironment remodeling. As indicated, their function in immune evasion, drug resistance, and metabolic reprogramming remains largely unexplored.

DNMT inhibitors reverse a specific signature of aberrant promoter DNA methylation and associated gene silencing in AML [PDF]

open access: yes, 2014
<b>Background</b>. Myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) are neoplastic disorders of hematopoietic stem cells. DNA methyltransferase inhibitors (DNMTi), 5-azacytidine (AzaC) and 5-aza-2’-deoxycytidine (Decitabine),

Dysplasia in sessile serrated lesions: frequency, interobserver variability and added value of immunohistochemistry

open access: yesHistopathology, EarlyView.
Sessile serrated lesions with dysplasia represent a critical step in colorectal carcinogenesis. While routine histologic diagnosis is generally reliable and positive diagnostic trends are observed, subtle dysplastic changes may be overlooked. Targeted use of MLH1 immunohistochemistry provides meaningful diagnostic support in selected sessile serrated ...

Global DNA hypomethylation prevents consolidation of differentiation programs and allows reversion to the embryonic stem cell state. [PDF]

open access: yes, 2012
DNA methylation patterns change dynamically during mammalian development and lineage specification, yet scarce information is available about how DNA methylation affects gene expression profiles upon differentiation.

Teeing Up Transcription on CpG Islands [PDF]

open access: yesJournal of End-to-End-testing, 2009
Eukaryotic cells use elaborate molecular mechanisms to rapidly activate signal-dependent gene expression. New work provides fresh insights into these mechanisms by demonstrating that CpG islands in promoters are nucleosome-destabilizing elements and can facilitate the establishment of an unusual poised transcriptional state (Ramirez-Carrozzi et al ...

Genome‐wide and gene‐specific DNA methylation across developmental stages in Pogonomyrmex californicus: A socially polymorphic ant

open access: yesInsect Molecular Biology, EarlyView.
Comparison between developmental stages (larvae, pupae, worker) in Pogonomyrmex californicus revealed significant stage‐specific differences in Gene Body Methylated frequencies. Methylation sites were highly correlated between WGBS and ONT in P. californicus Genome‐wide methylation was low (~3%) and highly clustered within gene bodies (GBM), especially

Retrotransposon silencing by DNA methylation can drive mammalian genomic imprinting [PDF]

open access: yes, 2015
Among mammals, only eutherians and marsupials are viviparous and have genomic imprinting that leads to parent-of-origin-specific differential gene expression. We used comparative analysis to investigate the origin of genomic imprinting in mammals. PEG10 (
