Variant-specific pathophysiological mechanisms of AFF3 differently influence transcriptome profiles
Giovanna Ambrosini, Nicolas Jean Philippe Guex, Christian Iseli
Background: We previously described the KINSSHIP syndrome, an autosomal dominant disorder associated with intellectual disability (ID), mesomelic dysplasia and horseshoe kidney,caused by de novo variants in the degron of AFF3. Mouse knock-ins and overexpre ...
BMC2024Targeted search for scaling genes reveals matrix metalloproteinase 3 as a scaler of the dorsal-ventral pattern in Xenopus laevis embryos
How embryos scale patterning according to size is still not fully understood. Through in silico screening and analysis of reaction-diffusion systems that could be responsible for scaling, we predicted the existence of genes whose expression is sensitive to ...
2022Histone acetylation dynamics modulates chromatin conformation and allele-specific interactions at oncogenic loci
Elisa Oricchio, Daniele Tavernari, Natalya Katanayeva, Stephanie Jocelyne Sungalee, Ruxandra-Andreea Lambuta, Giovanni Ciriello
In cancer cells, enhancer hijacking mediated by chromosomal alterations and/or increased deposition of acetylated histone H3 lysine 27 (H3K27ac) can support oncogene expression. However, how the chromatin conformation of enhancer-promoter interactions is a ...
2021TRIM28 repression of retrotransposon-based enhancers is necessary to preserve transcriptional dynamics in embryonic stem cells
Didier Trono, Adamantia Kapopoulou, Andrea Corsinotti, Helen Mary Rowe, Johan Jakobsson
TRIM28 is critical for the silencing of endogenous retroviruses (ERVs) in embryonic stem (ES) cells. Here, we reveal that an essential impact of this process is the protection of cellular gene expression in early embryos from perturbation by cis-acting act ...
2013Role of non-specific DNA in reducing coding DNA requirement for transient gene expression with CHO and HEK-293E cells
Florian Maria Wurm, David Hacker, Lucia Baldi Unser, Yashas Rajendra, Divor Kiseljak, Sagar Shashidhar Manoli
Transient gene expression (TGE) is a rapid method for the production of recombinant proteins in mammalian cells. While the TGE volumetric productivity has improved significantly over the past decade, the amount of plasmid DNA (pDNA) needed for transfection ...
2012Validation of Housekeeping Genes for Gene Expression Studies in Symbiodinium Exposed to Thermal and Light Stress
Unicellular photosynthetic algae (dinoflagellate) from the genus Symbiodinium live in mutualistic symbiosis with reef-building corals. Cultured Symbiodinium sp. (clade C) were exposed to a range of environmental stresses that included elevated temperatures ...
2011Histone methyl transferases and demethylases; can they link metabolism and transcription?
Johan Auwerx, Kristina Schoonjans
Heritable changes to the transcriptome that are independent to changes in the genome are defined as epigenetics. DNA methylation and posttranslational modifications of histones, such as acetylation/deacetylation and methylation/demethylation of lysine resi ...
Elsevier2010Gene transpositions in the HoxD complex reveal a hierarchy of regulatory controls
Vertebrate Hox genes are activated following a temporal sequence that reflects their linear order in the clusters. We introduced two Hoxd transcription units, labeled with lacZ, to an ectopic 5' position in the HoxD complex. Early expression of the relocat ...
