The Phosphoinositide 3-Kinase p110 alpha Isoform Regulates Leukemia Inhibitory Factor Receptor Expression via c-Myc and miR-125b to Promote Cell Proliferation in Medulloblastoma

Medulloblastoma (MB) is the most common malignant brain tumor in childhood and represents the main cause of cancer-related death in this age group. The phosphoinositide 3-kinase (PI3K) pathway has been shown to play an important role in the regulation of m ...

Intestinal steroidogenesis controls PPAR expression in the colon and is impaired during ulcerative colitis

Johan Auwerx

Background and aims Immune tolerance breakdown during UC involves the peroxisome proliferator-activated receptor- (PPAR), a key factor in mucosal homoeostasis and the therapeutic target of 5-aminosalycilates, which expression is impaired during UC. Here we ...

Assessing essentiality of transketolase in Mycobacterium tuberculosis using an inducible protein degradation system

Stewart Cole, Claudia Sala, Anthony Vocat, Gaëlle Séraphine Kolly

Improved genetic tools are required to identify new drug targets in Mycobacterium tuberculosis. To this aim, genetic approaches, targeting either transcription and/or protein degradation, have been developed to appraise gene essentiality and to test the im ...

Spatial separation of Xist RNA and polycomb proteins revealed by superresolution microscopy

Marion Leleu

In female mammals, one of the two X chromosomes is transcriptionally silenced to equalize X-linked gene dosage relative to XY males, a process termed X chromosome inactivation. Mechanistically, this is thought to occur via directed recruitment of chromatin ...

An evolutionarily conserved role for the aryl hydrocarbon receptor in the regulation of movement

Johan Auwerx, Bart Deplancke, Laurent Mouchiroud, Pénélope Andreux, Evan Graehl Williams, Michael Vincent Frochaux

The BXD genetic reference population is a recombinant inbred panel descended from crosses between the C57BL/6 (B6) and DBA/2 (D2) strains of mice, which segregate for about 5 million sequence variants. Recently, some of these variants have been established ...

HTT-lowering reverses Huntington's disease immune dysfunction caused by NF kappa B pathway dysregulation

Huntington's disease is an inherited neurodegenerative disorder caused by a CAG repeat expansion in the huntingtin gene. The peripheral innate immune system contributes to Huntington's disease pathogenesis and has been targeted successfully to modulate dis ...

Exploring new therapeutic strategies for Huntington's Disease

Wanqiu Hu

Huntington’s disease (HD) is an inherited neurodegenerative disorder caused by an extended poly-glutamine tract in the huntingtin gene (HTT). Despite intensive efforts in understanding its pathogenesis over the decades, effective treatments for HD remain u ...

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 ...

Insect endosymbiont proliferation is limited by lipid availability

Bruno Lemaitre, Juan Camilo Paredes Escobar, Jeremy Keith Herren

Spiroplasma poulsonii is a maternally transmitted bacterial endosymbiont that is naturally associated with Drosophila melanogaster. S. poulsonii resides extracellularly in the hemolymph, where it must acquire metabolites to sustain proliferation. In this s ...

Transgene- and locus-dependent imprinting reveals allele-specific chromosome conformations

Denis Duboule, Jozsef Zakany, Nicolas Lonfat

When positioned into the integrin alpha-6 gene, an Hoxd9lacZ reporter transgene displayed parental imprinting in mouse embryos. While the expression from the paternal allele was comparable with patterns seen for the same transgene when present at the neigh ...
