Hemagglutinin of Influenza A, but not of Influenza B and C viruses is acylated by ZDHHC2, 8, 15 and 20

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Mohamed Adbelalim Gadalla

Hemagglutinin (HA), a glycoprotein of Influenza A viruses and its proton channel M2 are site-specifically modified with fatty acids. Whereas two cysteines in the short cytoplasmic tail of HA contain only palmitate, stearate is exclusively attached to one c ...

Computational design of anti-CRISPR proteins with improved inhibition potency

Bruno Emanuel Ferreira De Sousa Correia, Sandrine Madeleine Suzanne Georgeon, Zander Harteveld, Andreas Scheck, Wei Sun, Stéphane Rosset, Julius Valten Upmeier Zu Belzen, Yujia Wang

Anti-CRISPR (Acr) proteins are powerful tools to control CRISPR-Cas technologies. However, the available Acr repertoire is limited to naturally occurring variants. Here, we applied structure-based design on AcrIIC1, a broad-spectrum CRISPR-Cas9 inhibitor, ...

Machine learning-based tools to model and to remove the off-target effect

François Fleuret

A RNA interference, also called a gene knockdown, is a biological technique which consists of inhibiting a targeted gene in a cell. By doing so, one can identify statistical dependencies between a gene and a cell phenotype. However, during such a gene inhi ...

Potential Direct Regulators of the Drosophila yellow Gene Identified by Yeast One-Hybrid and RNAi Screens

Bart Deplancke

The regulation of gene expression controls development, and changes in this regulation often contribute to phenotypic evolution. Drosophila pigmentation is a model system for studying evolutionary changes in gene regulation, with differences in expression ...

Enhanced Plasmid DNA Utilization in Transiently Transfected CHO-DG44 Cells in the Presence of Polar Solvents

Florian Maria Wurm, David Hacker, Lucia Baldi Unser, Yashas Rajendra, Divor Kiseljak, Sowmya Balasubramanian

Although the protein yields from transient gene expression (TGE) with Chinese hamster ovary (CHO) cells have recently improved, the amount of plasmid DNA (pDNA) needed for transfection remains relatively high. We describe a strategy to reduce the pDNA amou ...

Tuberculosis drug discovery in the post-post-genomic era

Stewart Cole, Jan Lars Rybniker, Benoit Lechartier

The expectation that genomics would result in new therapeutic interventions for infectious diseases remains unfulfilled. In the post-genomic era, the decade immediately following the availability of the genome sequence of Mycobacterium tuberculosis, tuberc ...

The Use of Valproic Acid in Transient Gene Expression with HEK-293E Cells

Divor Kiseljak

Transient gene expression (TGE) is a rapid method for the production of recombinant proteins. Recently, valproic acid (VPA), a well known histone deacetylase inhibitor, has been suggested for the use in cell cultures to enhance recombinant protein expressi ...

GABA Signaling Promotes Synapse Elimination and Axon Pruning in Developing Cortical Inhibitory Interneurons

Graham Knott, Yu Fu

Accumulating evidence indicates that GABA acts beyond inhibitory synaptic transmission and regulates the development of inhibitory synapses in the vertebrate brain, but the underlying cellular mechanism is not well understood. We have combined live imaging ...

Activin Signalling in Human Melanoma Cells

Susanna Eveliina Kallioinen

Melanoma, the most fatal of all skin cancers, by unknown mechanisms overcomes the cytostatic effects of TGFβ, while maintaining the TGFβ signaling needed for its tumor promoting functions. Besides TGFβ, ectopic induction of the TGFβ family member Nodal has ...

Variegated gene expression caused by cell-specific long-range DNA interactions

Daniël Noordermeer

Mammalian genomes contain numerous regulatory DNA sites with unknown target genes. We used mice with an extra β-globin locus control region (LCR) to investigate how a regulator searches the genome for target genes. We find that the LCR samples a restricted ...
