V-ATPase/TORC1-mediated ATFS-1 translation directs mitochondrial UPR activation in C. elegans

Johan Auwerx, Kristina Schoonjans, Felix Naef, Xiaoxu Li, Jia Liu, Hao Li, Wen Gao, Nagammal Neelagandan, Yang Li, Amélia Lalou

To adapt mitochondrial function to the ever-changing intra- and extracellular environment, multiple mitochondrial stress response (MSR) pathways, including the mitochondrial unfolded protein response (UPRmt), have evolved. However, how the mitochondrial st ...

The angiopoietin-Tie2 pathway regulates Purkinje cell dendritic morphogenesis in a cell-autonomous manner

Michele De Palma

Neuro-vascular communication is essential to synchronize central nervous system development. Here, we identify angiopoietin/Tie2 as a neuro-vascular signaling axis involved in regulating dendritic morphogenesis of Purkinje cells (PCs). We show that in the ...

Structural basis of drug recognition by the multidrug transporter ABCG2

Henning Paul-Julius Stahlberg, Dongchun Ni

ABCG2 is an ATP-binding cassette (ABC) transporter whose function affects the pharmacokinetics of drugs and contributes to multidrug resistance of cancer cells. While its interaction with the endogenous substrate estrone-3-sulfate (E1S) has been elucidated ...

Enhancing the Signaling of GPCRs via Orthosteric Ions

Horst Vogel, Shuguang Yuan

G protein-coupled receptors play essential roles in cellular processes such as neuronal signaling, vision, olfaction, tasting, and metabolism. As GPCRs are the most important drug targets, understanding their interactions with ligands is of utmost importan ...

Human T-Cell Lymphotropic Virus Type 1 Transactivator Tax Exploits the XPB Subunit of TFIIH during Viral Transcription

Human T-cell lymphotropic virus type 1 (HTLV-1) Tax oncoprotein is required for viral gene expression. Tax transactivates the viral promoter by recruiting specific transcription factors but also by interfering with general transcription factors involved in ...

Sodium Signaling and Astrocyte Energy Metabolism

Pierre Magistretti, Jean-Yves Chatton

The Na+ gradient across the plasma membrane is constantly exploited by astrocytes as a secondary energy source to regulate the intracellular and extracellular milieu, and discard waste products. One of the most prominent roles of astrocytes in the brain is ...

A Balance between Inhibitor Binding and Substrate Processing Confers Influenza Drug Resistance

Jeffrey David Jensen, Claudia Bank, Li Jiang

The therapeutic benefits of the neuraminidase (NA) inhibitor oseltamivir are dampened by the emergence of drug resistance mutations in influenza A virus (IAV). To investigate the mechanistic features that underlie resistance, we developed an approach to qu ...

alpha-Synuclein-induced dopaminergic neurodegeneration in a rat model of Parkinson's disease occurs independent of ATP13A2 (PARK9)

Bernard Schneider, Elpida Tsika, Liliane Glauser, Alessandra Musso, Guillaume Daniel, Darren Moore, Aris Nikolaos Fiser

Mutations in the ATP13A2 (PARK9) gene cause early-onset, autosomal recessive Parkinson's disease (PD) and Kufor-Rakeb syndrome. ATP13A2 mRNA is spliced into three distinct isoforms encoding a P5-type ATPase involved in regulating heavy metal transport acro ...

Assessment of Pseudo-Bilayer Structures in the Heterogate Germanium Electron-Hole Bilayer Tunnel Field-Effect Transistor

Mihai Adrian Ionescu, Cem Alper, José Luis Padilla de la Torre

We investigate the effect of pseudo-bilayer configurations at low operating voltages (

Learning-Induced Gene Expression in the Hippocampus Reveals a Role of Neuron-Astrocyte Metabolic Coupling in Long Term Memory

Pierre Magistretti, Igor Allaman, Gabriele Grenningloh, Sylvain Eric Lengacher, Monika Tadi

We examined the expression of genes related to brain energy metabolism and particularly those encoding glia (astrocyte)-specific functions in the dorsal hippocampus subsequent to learning. Context-dependent avoidance behavior was tested in mice using the s ...
