Single-molecule sensing of peptides and nucleic acids by engineered aerolysin nanopores

Aleksandra Radenovic, Matteo Dal Peraro, Chan Cao

Nanopore sensing is a powerful single-molecule approach for the detection of biomolecules. Recent studies have demonstrated that aerolysin is a promising candidate to improve the accuracy of DNA sequencing and to develop novel single-molecule proteomic str ...

Genie in a bottle: controlled release helps tame natural polypharmacology?

Yimon Aye, Xuyu Liu

Ability to faithfully report drug-target interactions constitutes a major critical parameter in preclinical/clinical settings. Yet the assessment of target engagement remains challenging, particularly for promiscuous and/or polypharmacologic ligands. Drawi ...

Weighing up the Selenocysteome Uncovers New Sec-rets

Yimon Aye, Jesse Poganik

Challenging the paradigm of SECIS-dependent selenoprotein translation, in this issue of Cell Chemical Biology Guo et al. (2018) introduce a new selenoprotein profiling platform with which they identify novel selenoproteins apparently lacking SECIS. With in ...

Microfluidic systems for high-throughput and high-content screening using the nematode Caenorhabditis elegans

Martinus Adela Maria Gijs, Thomas Lehnert, Matteo Cornaglia

In a typical high-throughput drug screening (HTS) process, up to millions of chemical compounds are applied to cells cultured in well plates, aiming to find molecules that exhibit a robust dose-response, as evidenced for example by a fluorescence signal. I ...

Electrostatic spray ionization from 384-well microtiter plates for mass spectrometry analysis based enzyme assay and drug metabolism screening

Hubert Girault, Liang Qiao, Tzu-En Lin, Elena Tobolkina, Xiaoqin Zhong

We have realized the direct ionization of samples from wells of microtiter plates under atmospheric conditions for mass spectrometry analysis without any liquid delivery system or any additional interface. The microtiter plate is a commercially available 3 ...

Nanoscale Sensors for Ultrasensitive Label-free Detection of Cancer Biomarkers and Monitoring of Therapeutic Compounds

Ioulia Tzouvadaki

Prostate cancer is a life-threatening malignant disease, one the most common cancer types in men and leading cause of death among men because of cancer. Considering the state of the art for the diagnosis of prostate cancer a man overall has to suffer uncom ...

Inhibiting Mycobacterium tuberculosis within and without

Stewart Cole

Tuberculosis remains a scourge of global health with shrinking treatment options due to the spread of drug-resistant strains of Mycobacterium tuberculosis. Intensive efforts have been made in the past 15 years to find leads for drug development so that bet ...

Does Proton Conduction in the Voltage-Gated H+ Channel hHv1 Involve Grotthuss-Like Hopping via Acidic Residues?

Ursula Röthlisberger, Siri Camee van Keulen, Lucie Monique Françoise Delemotte

Hv1s are ubiquitous highly selective voltage-gated proton channels involved in male fertility, immunology, and the invasiveness of certain forms of breast cancer. The mechanism of proton extrusion in Hv1 is not yet understood, while it constitutes the firs ...

The Principles of Ligand Specificity on beta-2-adrenergic receptor

Shuguang Yuan

G protein-coupled receptors are recognized as one of the largest families of membrane proteins. Despite sharing a characteristic seven-transmembrane topology, G protein-coupled receptors regulate a wide range of cellular signaling pathways in response to v ...
