Direct observation of small molecule activator binding to single PR65 protein.

The reactivation of heterotrimeric protein phosphatase 2A (PP2A) through small molecule activators is of interest to therapeutic intervention due to its dysregulation, which is linked to chronic conditions. This study focuses on the PP2A scaffold subunit PR65 and a small molecule activator, ATUX-8385, designed to bind directly to this subunit. Using a label-free single-molecule approach with nanoaperture optical tweezers (NOT), we quantify its binding, obtaining a dissociation constant of 13.

Translation and validation of the Nature Relatedness Scale to German.

Over the recent past, tools have been developed to asses people's connection to and attitudes towards nature due to increasing interest in this topic in society and research. We translated one such questionnaire, the Nature Relatedness Scale, consisting of three subscales (NR-Self, NR-Perspective, NR-Experience) to German. We collected 251 data sets and performed a confirmatory factor analysis, followed by an exploratory factor analysis.

PP2A activation overcomes leptomeningeal dissemination in group 3 medulloblastoma.

Leptomeningeal dissemination (LMD) is the primary cause of treatment failure in children with group 3 medulloblastoma (MB). Building on our previous work on protein phosphatase 2A (PP2A) activation in MB, here we present preclinical and molecular data on the effects of two novel classes of PP2A activators on disease processes of LMD in group 3 MB. The PP2A activators used in this study are ATUX-6156 and ATUX-6954 (diarylmethylcycloamine sulfonylureas), and ATUX-1215 and ATUX-5800 (diarylmethyl-4-aminotetrahydropyran-sulfonamides).

Pinewood VOC emissions protect from oxazolone-induced inflammation and dysbiosis in a mouse model of atopic dermatitis.

Pinewood, increasingly used in construction and interior fittings, emits high amounts of volatile organic compounds (VOCs), which tend to accumulate in indoor air. Whether indoor VOCs affect the development of atopic dermatitis (AD) is a matter of debate. We aimed to evaluate the effects of pinewood VOCs on the development of AD-like inflammatory phenotype and linked microbiome alterations, both hallmarks of AD.
