Metabolic plasticity and glucose transporter redundancy dictate lung adenocarcinoma growth

Caroline Anne-Lyse Contat

Lung cancers represent the leading cause of cancer-related deaths worldwide. These pulmonary cancers count several histological subgroups, whose non-small cell lung cancers, subject of our study. We were precisely interested in the most common subtype of n ...

Long noncoding RNA SNHG12 integrates a DNA-PK-mediated DNA damage response and vascular senescence

Johan Auwerx, Norman Lionel Moullan

Long noncoding RNAs (lncRNAs) are emerging regulators of biological processes in the vessel wall; however, their role in atherosclerosis remains poorly defined. We used RNA sequencing to profile lncRNAs derived specifically from the aortic intima of Ldlr(- ...

Sirt6 deletion in bone marrow-derived cells increases atherosclerosis - Central role of macrophage scavenger receptor 1

Johan Auwerx

Aims: Sirtuin 6 (Sirt6) is a NAD(+)-dependent deacetylase that plays a key role in DNA repair, inflammation and lipid regulation. Sirt6-null mice show severe metabolic defects and accelerated aging. Macrophage-foam cell formation via scavenger receptors is ...

Mitochondrial Deacetylase Sirt3 Reduces Vascular Dysfunction and Hypertension While Sirt3 Depletion in Essential Hypertension Is Linked to Vascular Inflammation and Oxidative Stress

Johan Auwerx

Rationale: Hypertension represents a major risk factor for stroke, myocardial infarction, and heart failure and affects 30% of the adult population. Mitochondrial dysfunction contributes to hypertension, but specific mechanisms are unclear. The mitochondri ...

The Tumor Microenvironment as a Driving Force of Breast Cancer Stem Cell Plasticity

Albert Santamaria Martinez

Simple Summary Breast cancer stem cells are a subset of transformed cells that sustain tumor growth and can metastasize to secondary organs. Since metastasis accounts for most cancer deaths, it is of paramount importance to understand the cellular and mole ...

Tp63-expressing adult epithelial stem cells cross lineages boundaries revealing latent hairy skin competence

Yann Barrandon, Ariane Rochat, Paola Bonfanti, Stéphanie Claudinot, Christèle Gonneau

The formation of hair follicles, a landmark of mammals, requires complex mesenchymal-epithelial interactions and it is commonly believed that embryonic epidermal cells are the only cells that can respond to hair follicle morphogenetic signals in vivo. Here ...

High-content, cell-by-cell assessment of HER2 overexpression and amplification: a tool for intratumoral heterogeneity detection in breast cancer

Martinus Adela Maria Gijs, Daniel Migliozzi, Huu Tuan Nguyen

Immunohistochemistry and fluorescence in situ hybridization are the two standard methods for human epidermal growth factor receptor 2 (HER2) assessment. However, they have severe limitations to assess quantitatively intratumoral heterogeneity (ITH) when mu ...

Premature activation of Cdk1 leads to mitotic events in S phase and embryonic lethality

João Pedro de Matos Rodrigues, Patricia Renck Nunes

Cell cycle regulation, especially faithful DNA replication and mitosis, are crucial to maintain genome stability. Cyclin-dependent kinase (CDK)/cyclin complexes drive most processes in cellular proliferation. In response to DNA damage, cell cycle surveilla ...

Carboplatin/paclitaxel, E7-vaccination and intravaginal CpG as tri-therapy towards efficient regression of genital HPV16 tumors

Douglas Hanahan, Gabriele Galliverti

High-risk human papillomavirus (HPV) are responsible for genital and oral cancers associated with the expression of the E6/E7 HPV oncogenes. Therapeutic vaccines targeting those oncogenes can only partially control tumor progression, highlighting the neces ...

Control of Hox transcription factor concentration and cell-to-cell variability by an auto-regulatory switch

The variability in transcription factor concentration among cells is an important developmental determinant, yet how variability is controlled remains poorly understood. Studies of variability have focused predominantly on monitoring mRNA production noise. ...

Electrochemical detection of different p53 conformations by using nanostructured surfaces

Sandro Carrara, Francesca Stradolini, Sarah Tonello

Protein electrochemistry represents a powerful technique for investigating the function and structure of proteins. Currently available biochemical assays provide limited information related to the conformational state of proteins and high costs. This work ...

Phosphorylation of α-synuclein is crucial in compensating for proteasomal dysfunction

Hilal Lashuel

α-Synuclein can be degraded by both the ubiquitin-proteasomal system and the chaperone-lysosomal system. However, the switching mechanism between the two pathways is not clearly understood. In our study, we investigated the mutual association between the b ...
