Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

open access: yesFEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Impedance analysis and single ion channel recordings on pore-suspending lipid bilayers based on highly ordered pore arrays

open access: yes, 2006
Ion channels are one of the main drug targets and are in the focus of various membrane biosensor applications and drug screening assays. The aim of this thesis was to develop and characterize a novel membrane system suspending highly ordered porous ...

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

open access: yesFEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Identification of a unique Ca2+-binding site in rat acid-sensing ion channel 3

open access: yesNature Communications, 2018
Acid-sensing ion channels (ASICs) sense changes in extracellular acidity with Ca2+ as an allosteric modulator and channel blocker. Here authors use electrophysiology and molecular dynamics simulation to identify the residue in ASIC3 which modulates ...

Role of acid-sensing ion channels in hypoxia- and hypercapnia-induced ventilatory responses. [PDF]

open access: yesPLoS ONE, 2018
Previous reports indicate roles for acid-sensing ion channels (ASICs) in both peripheral and central chemoreception, but the contributions of ASICs to ventilatory drive in conscious, unrestrained animals remain largely unknown.

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

open access: yesFEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Layer-by-layer assembly of organic films and their application to multichannel surface plasmon resonance sensing [PDF]

open access: yes, 2004
This thesis provides a study of a single chip, multi-channel surface plasmon resonance (SPR) imaging system. The equipment has no moving parts and uses a single sensor "chip" onto which multiple channels can be incorporated.

Hyperactive ice‐binding proteins stabilize cell membranes and improve resistance to dehydration stress in Caenorhabditis elegans

open access: yesFEBS Open Bio, EarlyView.
TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.

An acid-sensing ion channel that detects ischemic pain [PDF]

open access: yesBrazilian Journal of Medical and Biological Research, 2005
Ischemic pain occurs when there is insufficient blood flow for the metabolic needs of an organ. The pain of a heart attack is the prototypical example. Multiple compounds released from ischemic muscle likely contribute to this pain by acting on sensory neurons that innervate muscle. One such compound is lactic acid.

A heteromeric Texas coral snake toxin targets acid-sensing ion channels to produce pain [PDF]

open access: yes, 2011
Coral snake's potent toxin identifiedThe bite of the Texas coral snake, although not fatal, causes excruciating and long-lasting pain. The toxin involved has now been characterized.
