A minimalistic cyclic ice-binding peptide from phage display

Harm-Anton Klok, Luciano Andres Abriata, Xudong Kong, Corey Alfred Stevens

Developing molecules that emulate the properties of naturally occurring ice-binding proteins (IBPs) is a daunting challenge. Rather than relying on the (limited) existing structure–property relationships that have been established for IBPs, here we report ...

How General Is Anomeric Retention during Collision-Induced Dissociation of Glycans?

Thomas Rizzo, Ahmed Ben Faleh, Stephan Warnke, Eduardo Carrascosa Casado, Robert Paul Pellegrinelli, Lei Yue

: Despite the essential role that glycans play in many biological processes, their isomeric com-plexity makes their structural determination partic-ularly challenging. Tandem mass spectrometry has played a central role in glycan analysis, and recent work h ...

Evaluation of the NAD(+) biosynthetic pathway in ALS patients and effect of modulating NAD(+) levels in hSOD1-linked ALS mouse models

Johan Auwerx

Amyotrophic lateral sclerosis (ALS) is characterized by progressive degeneration of motor neurons. Astrocytes from diverse ALS models induce motor neuron death in co-culture. Enhancing NAD(+) availability, or increasing the expression of the NAD(+)-depende ...

Proteins/peptides purification by a three-well OFFGEL electrophoresis with immobilized ultra narrow pH gradient gels

Hubert Girault, Liang Qiao, Fernando Cortes Salazar, Elena Tobolkina

Purification and desalting of protein and peptide samples by a three-well OFFGEL electrophoresis with immobilized ultra narrow pH gradient gels is proposed as a fast preparative strategy for proteomics. The gist of this strategy is to separate the proteins ...

Bile Acids Increase Levels of MicroRNAs 221 and 222, Leading to Degradation of CDX2 During Esophageal Carcinogenesis

Johan Auwerx

BACKGROUND & AIMS: Bile reflux contributes to development of Barrett's esophagus (BE) and could be involved in its progression to esophageal adenocarcinoma (EAC). We investigated whether bile acids affect levels or functions of microRNAs (MIRs) 221 and 222 ...

Double-balloon jejunal perfusion to compare absorption of vitamin E and vitamin E acetate in healthy volunteers under maldigestion conditions

BACKGROUND/OBJECTIVES: The vitamin E derivative, alpha-tocopheryl acetate, is often included in formulations used in enteral nutrition. In this respect, we compared alpha-tocopherol and alpha-tocopheryl acetate absorption under 'maldigestion' conditions, s ...

Mycobacterium tuberculosis persistence mutants identified by screening in isoniazid-treated mice

John McKinney, Neeraj Dhar

Tuberculosis (TB) is notoriously difficult to cure, requiring administration of multiple antibiotics for 6 mo or longer. Conventional anti-TB drugs inhibit biosynthetic processes involved in cell growth and division, such as DNA replication, RNA transcript ...
