Quantitative single cell dynamics of signaling and transcriptional response in mammalian cells

Onur Tidin

Cells live in ever-changing environments, thereby facing a variety of dynamic environmental signals. Environmental stimuli elicit intracellular responses through signaling pathways, which converge on transcriptional activation or repression of target genes ...

Generation of Native, Untagged Huntingtin Exon1 Monomer and Fibrils Using a SUMO Fusion Strategy

Hilal Lashuel, Anass Chiki, Jonathan Jean-Pierre Ricci, Andreas Reif

Huntington’s Disease (HD) is an inherited fatal neurodegenerative disease caused by a CAG expansion (36) in the first exon of the HD gene, resulting in the expression of the Huntingtin protein (Htt) or N-terminal fragments thereof with an expanded polygl ...

The Inosine Monophosphate Dehydrogenase, GuaB2, Is a Vulnerable New Bactericidal Drug Target for Tuberculosis

Stewart Cole, John McKinney, Claudia Sala, Neeraj Dhar, Anthony Vocat, Ruben Hartkoorn, Andréanne Lupien, Raphael Christopher Sommer

VCC234718, a molecule with growth inhibitory activity against Mycobacterium tuberculosis (Mtb), was identified by phenotypic screening of a 15344-compound library. Sequencing of a VCC234718-resistant mutant identified a Y487C substitution in the inosine mo ...

KRAB'n'KAP, DNA methylation and epigenetic memory

Andrea Coluccio

The KZFP/KAP1 (Krüppel associated box zinc finger proteins/KRAB-associated protein 1) complex is a transcriptional repressor that triggers the deposition of heterochromatin (H3K9me3) and DNA methylation. The main targets of the KZFP/KAP1 complex are transp ...

Genomic targets and molecular partners of the chromatin regulator KAP1

Annamaria Kauzlaric

KAP1 is an enigmatic regulatory protein, first described some twenty years ago, shown to be involved in multiple and diverse cellular functions. Specifically, it mediates tasks critical to cell growth and differentiation, pluripotency, apoptosis, gene sile ...

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 ...

AAV based gene therapy for rare diseases : targeting astrocytes for functional recovery in Amyotrophic Lateral Sclerosis

Cylia Cloé Rochat

Of the seven thousand diseases that are described as rare, 80% of them have an identified genetic cause. With this in the mind, the development of technologies, such as gene therapy, to address the genetic factors involved in these pathologies, might be a ...

Functional analysis of Bicc1 and novel interacting proteins in renal tubule cell metabolism and polycystic kidneys

Lucía Carolina Leal Esteban

Genetic disorders known as ciliopathies develop polycystic kidneys, including autosomal dominant and autosomal recessive polycystic kidney diseases (ADPKD and ARPKD). Several signaling pathways including the cAMP/PKA pathway are implicated in driving cyst ...
