Epigenetics in ovarian cancer: premise, properties, and perspectives. [PDF]

, 2018
Malignant ovarian tumors bear the highest mortality rate among all gynecological cancers. Both late tumor diagnosis and tolerance to available chemical therapy increase patient mortality.

Histone demethylase JMJD1C is phosphorylated by mTOR to activate de novo lipogenesis. [PDF]

, 2020
Fatty acid and triglyceride synthesis increases greatly in response to feeding and insulin. This lipogenic induction involves coordinate transcriptional activation of various enzymes in lipogenic pathway, including fatty acid synthase and glycerol-3 ...

Interleukin-4-mediated 15-lipoxygenase-1 trans-activation requires UTX recruitment and H3K27me3 demethylation at the promoter in A549 cells. [PDF]

PLoS ONE, 2014
Arachidonate 15-lipoxygenase-1 (ALOX15) oxygenates polyunsaturated fatty acids and bio-membranes, generating multiple lipid signalling mediators involved in inflammation.

SUVH1, a Su(var)3-9 family member, promotes the expression of genes targeted by DNA methylation. [PDF]

, 2015
Transposable elements are found throughout the genomes of all organisms. Repressive marks such as DNA methylation and histone H3 lysine 9 (H3K9) methylation silence these elements and maintain genome integrity.

Liquid biopsy epigenetics: establishing a molecular profile based on cell‐free DNA

Molecular Oncology, EarlyView.
Cell‐free DNA (cfDNA) fragments in plasma from cancer patients carry epigenetic signatures reflecting their cells of origin. These epigenetic features include DNA methylation, nucleosome modifications, and variations in fragmentation. This review describes the biological properties of each feature and explores optimal strategies for harnessing cfDNA ...

Rebalancing gene haploinsufficiency in vivo by targeting chromatin

Nature Communications, 2016
Deficit in transcription factor Tbx1 causes heart defects in humans and mice. Here the authors show that Tbx1 regulates gene expression by recruiting histone methyltransferases that affect chromatin marks, and that a drug inhibiting histone demethylation

LSD1-mediated enhancer silencing attenuates retinoic acid signalling during pancreatic endocrine cell development. [PDF]

, 2020
Developmental progression depends on temporally defined changes in gene expression mediated by transient exposure of lineage intermediates to signals in the progenitor niche.

Cis‐regulatory and long noncoding RNA alterations in breast cancer – current insights, biomarker utility, and the critical need for functional validation

Molecular Oncology, EarlyView.
The noncoding region of the genome plays a key role in regulating gene expression, and mutations within these regions are capable of altering it. Researchers have identified multiple functional noncoding mutations associated with increased cancer risk in the genome of breast cancer patients.

Structural Insights into Histone Demethylation by JMJD2 Family Members [PDF]

Cell, 2006
Posttranslational modifications of histones regulate chromatin structure and gene expression. Histone demethylases, members of a newly emerging transcription-factor family, remove methyl groups from the lysine residues of the histone tails and thereby regulate the transcriptional activity of target genes.

Methylation status of Dnmt1 promoter depends on poly(ADP-ribosy)lation [PDF]

, 2007
Research is focused on CpG islands and on the mechanism that poly(ADP-ribosyl)ation uses to defend the unmethylated state of these important DNA sequences which are located in the promoter regions of the housekeeping genes having a role of transcription ...
