Purification and characterization of the intrinsically disordered Arabidopsis thaliana protein SOG1.

SOG1, a transcription factor consisting of a folded NAC (NAM-ATAF-CUC2) domain and an intrinsically disordered C-terminal domain (CTD), co-ordinates the DNA damage response in plants. Here we compare different methods to express and purify recombinant full length Arabidopsis thaliana SOG1. Expression in Sf9 insect cells results in a protein that contains a phosphorylated site that is possibly located on the T423 site in the CTD.

Human Intervention Study: Alkylresorcinol Metabolites as Potential Biomarkers for Grain Intake and the Occurrence of Alkylresorcinols in Commonly Consumed Foods in the German Retail Sector.

Grains are one of the primary nutrients and are associated with many health benefits. To reflect the intake of grain-based products, two promising potential biomarkers are alkylresorcinol (AR) metabolites 3,5-dihydroxybenzoic acid (3,5-DHBA) and 3-(3,5-dihydroxyphenyl)-propanoic acid (3,5-DHPPA). The aim of this study was to validate the occurrence of AR in food samples and investigate the suitability of their metabolites as potential biomarkers in human intervention studies.

Single domain antibodies from camelids in the treatment of microbial infections.

Infectious diseases continue to pose significant global health challenges. In addition to the enduring burdens of ailments like malaria and HIV, the emergence of nosocomial outbreaks driven by antibiotic-resistant pathogens underscores the ongoing threats. Furthermore, recent infectious disease crises, exemplified by the Ebola and SARS-CoV-2 outbreaks, have intensified the pursuit of more effective and efficient diagnostic and therapeutic solutions.

Peripheral HMGB1 is linked to O pathology of disease-associated astrocytes and amyloid.

Introduction: Ozone (O) is an air pollutant associated with Alzheimer's disease (AD) risk. The lung-brain axis is implicated in O-associated glial and amyloid pathobiology; however, the role of disease-associated astrocytes (DAAs) in this process remains unknown.

Methods: The O-induced astrocyte phenotype was characterized in 5xFAD mice by spatial transcriptomics and proteomics.

Evaluation of different strategies to produce Vibrio cholerae ParE2 toxin.

Toxin-antitoxin (TA) systems are small operons that are omnipresent in bacteria and archaea with suggested roles in stabilization of mobile genetic elements, bacteriophage protection, stress response and possibly persister formation. A major bottleneck in the study of TA toxins is the production of sufficient amounts of well-folded, functional protein. Here we examine alternative approaches for obtaining the VcParE2 toxin from Vibrio cholerae.
