Identification of an E3 ligase that targets the catalytic subunit ofRNA polymerase I upon transcription stress.
Published: November, 2022

Abstract: RNA polymerase I (Pol I) synthesizes ribosomal RNA (rRNA), which is the first and rate-limiting step in ribosome biogenesis. Factors governing the stability of the polymerase complex are not known. Previous studies characterizing the Pol I inhibit...

ZNF354C is a transcriptional repressor that inhibits endothelialangiogenic sprouting.
Published: November, 2020

Abstract: Zinc finger proteins (ZNF) are a large group of transcription factors with diverse functions. We recently discovered that endothelial cells harbour a specific mechanism to limit the action of ZNF354C, whose function in endothelial cells is unknown...

Formation of the CenH3-Deficient Holocentromere in Lepidoptera AvoidsActive Chromatin.
Published: October, 2020

Abstract: Despite the essentiality for faithful chromosome segregation, centromere architectures are diverse among eukaryotes and embody two main configurations: mono- and holocentromeres, referring, respectively, to localized or unrestricted distribution o...

CTCF is dispensable for immune cell transdifferentiation but facilitates an acute inflammatory response.
Published: June, 2020

Abstract: Three-dimensional organization of the genome is important for transcriptional regulation. In mammals, CTCF and the cohesin complex create submegabase structures with elevated internal chromatin contact frequencies, called topologically associating...

AP-1 controls the p11-dependent antidepressant response.
Published: May, 2020

Abstract: Selective serotonin reuptake inhibitors (SSRIs) are the most widely prescribed drugs for mood disorders. While the mechanism of SSRI action is still unknown, SSRIs are thought to exert therapeutic effects by elevating extracellular serotonin level...

Aging-regulated anti-apoptotic long non-coding RNA Sarrah augments recovery from acute myocardial infarction.
Published: April, 2020

Abstract: Long non-coding RNAs (lncRNAs) contribute to cardiac (patho)physiology. Aging is the major risk factor for cardiovascular disease with cardiomyocyte apoptosis as one underlying cause. Here, we report the identification of the aging-regulated lncRN...

UNBRANCHED3 Expression and Inflorescence Development is Mediated by UNBRANCHED2 and the Distal Enhancer, KRN4, in Maize.
Published: April, 2020

Abstract: Enhancers are cis-acting DNA segments with the ability to increase target gene expression. They show high sensitivity to DNase and contain specific DNA elements in an open chromatin state that allows the binding of transcription factors (TFs). Whi...

Unique Role of Histone Methyltransferase PRDM8 in the Tumorigenesis of Virus-Negative Merkel Cell Carcinoma.
Published: April, 2020

Abstract: Merkel cell carcinoma (MCC) is a deadly skin cancer, and about 80% of its cases have been shown to harbor integrated Merkel polyomavirus in the tumor cell genome. Viral oncoproteins expressed in the tumor cells are considered as the oncogenic fact...

The endocannabinoid anandamide has an anti-inflammatory effect on CCL2 expression in vascular smooth muscle cells.
Published: April, 2020

Abstract: Endocannabinoids are important lipid-signaling mediators. Both protective and deleterious effects of endocannabinoids in the cardiovascular system have been reported but the mechanistic basis for these contradicting observations is unclear. We set...

A MORC-driven transcriptional switch controls Toxoplasma developmental trajectories and sexual commitment.
Published: February, 2020

Abstract: Toxoplasma gondii has a complex life cycle that is typified by asexual development that takes place in vertebrates, and sexual reproduction, which occurs exclusively in felids and is therefore less studied. The developmental transitions rely on ch...

Inhibition of histone deacetylation rescues phenotype in a mouse model of Birk-Barel intellectual disability syndrome.
Published: January, 2020

Abstract: Mutations in the actively expressed, maternal allele of the imprinted KCNK9 gene cause Birk-Barel intellectual disability syndrome (BBIDS). Using a BBIDS mouse model, we identify here a partial rescue of the BBIDS-like behavioral and neuronal phen...

Interaction of Sox2 with RNA binding proteins in mouse embryonic stem cells.
Published: August, 2019

Abstract: Sox2 is a master transcriptional regulator of embryonic development. In this study, we determined the protein interactome of Sox2 in the chromatin and nucleoplasm of mouse embryonic stem (mES) cells. Apart from canonical interactions with pluripot...

Interleukin-22 protects intestinal stem cells against genotoxic stress.
Published: February, 2019

Abstract: Environmental genotoxic factors pose a challenge to the genomic integrity of epithelial cells at barrier surfaces that separate host organisms from the environment. They can induce mutations that, if they occur in epithelial stem cells, contribute...

Macrophage-specific MHCII expression is regulated by a remote enhancer controlled by NFAT5.
Published: October, 2018

Abstract: MHCII in antigen-presenting cells (APCs) is a key regulator of adaptive immune responses. Expression of MHCII genes is controlled by the transcription coactivator CIITA, itself regulated through cell type-specific promoters. Here we show that the ...

H3K4/K9 acetylation and Lr28-mediated expression of six leaf rust responsive genes in wheat (Triticum aestivum).
Published: October, 2018

Abstract: Development of leaf rust-resistant cultivars is a priority during wheat breeding, since leaf rust causes major losses in yield. Resistance against leaf rust due to Lr genes is partly controlled by epigenetic modifications including histone acetyla...

Lamin B1 mapping reveals the existence of dynamic and functional euchromatin lamin B1 domains.
Published: August, 2018

Abstract: Lamins (A/C and B) are major constituents of the nuclear lamina (NL). Structurally conserved lamina-associated domains (LADs) are formed by genomic regions that contact the NL. Lamins are also found in the nucleoplasm, with a yet unknown function....

27nt-RNAs guide histone variant deposition via 'RNA-induced DNA replication interference' and thus transmit parental genome partitioning in Stylonychia.
Published: June, 2018

Abstract: BACKGROUND: During sexual reproduction in the unicellular ciliate Stylonychia somatic macronuclei differentiate from germline micronuclei. Thereby, programmed sequence reduction takes place, leading to the elimination of > 95% of ...

The lncRNA GATA6-AS epigenetically regulates endothelial gene expression via interaction with LOXL2.
Published: January, 2018

Abstract: Impaired or excessive growth of endothelial cells contributes to several diseases. However, the functional involvement of regulatory long non-coding RNAs in these processes is not well defined. Here, we show that the long non-coding antisense tran...
