A Coarse-Grained Simulation Approach for Protein Molecular Conformation Dynamics.

J Phys Chem A

January 2025

Computer Modelling Group, 3710 33 St NW, Calgary, Alberta T2L 2M1, Canada.

Coarse-grained molecular dynamics simulation is widely accepted for assessment of a large complex biological system, but it may also lead to a misleading conclusion. The challenge is to simulate protein structural dynamics (such as folding-unfolding behavior) due to the lack of a necessary backbone flexibility. This study developed a standard coarse-grained model directly from the protein atomic structure and amino acid coarse-grained FF (such as MARTINI FF v2.

Hornworts, one of the three bryophyte phyla, show some of the deepest divergences in extant land plants, with some families separated by more than 300 million years. Previous hornwort genomes represented only one genus, limiting the ability to infer evolution within hornworts and their early land plant ancestors. Here we report ten new chromosome-scale genomes representing all hornwort families and most of the genera.

Pyrenoid-based CO-concentrating mechanisms (pCCMs) turbocharge photosynthesis by saturating CO around Rubisco. Hornworts are the only land plants with a pCCM. Owing to their closer relationship to crops, hornworts could offer greater translational potential than the green alga Chlamydomonas, the traditional model for studying pCCMs.

A nucleolar mechanism suppresses organismal proteostasis by modulating TGFβ/ERK signalling.

Nat Cell Biol

January 2025

Department of Biochemistry and Molecular Biology, the Institute for Medical Research Israel-Canada, the Faculty of Medicine, The Hebrew University of Jerusalem, Jerusalem, Israel.

The protein homeostasis (proteostasis) network encompasses a myriad of mechanisms that maintain the integrity of the proteome by controlling various biological functions, including protein folding and degradation. Alas, ageing-associated decline in the efficiency of this network enables protein aggregation and consequently the development of late-onset neurodegenerative disorders, such as Alzheimer's disease. Accordingly, the maintenance of proteostasis through late stages of life bears the promise to delay the emergence of these devastating diseases.

Rapid growth in bio-logging-the use of animal-borne electronic tags to document the movements, behaviour, physiology and environments of wildlife-offers opportunities to mitigate biodiversity threats and expand digital natural history archives. Here we present a vision to achieve such benefits by accounting for the heterogeneity inherent to bio-logging data and the concerns of those who collect and use them. First, we can enable data integration through standard vocabularies, transfer protocols and aggregation protocols, and drive their wide adoption.

Point-of-care ultrasound (POCUS) has emerged as a standard of care across a variety of healthcare settings due to its ability to provide critical clinical information and as well as procedural guidance to clinicians directly at the bedside. Implementation of enterprise imaging (EI) strategies is needed such that POCUS images can be appropriately captured, indexed, managed, stored, distributed, viewed, and analyzed. Because of its unique workflow and educational requirements, reliance on traditional order-based workflow solutions may be insufficient.

Microbial volatile organic compounds measured in the air of a waste sorting plant and a university by thermal desorption-gas chromatography-tandem mass spectrometry.

Environ Monit Assess

January 2025

Institut de Recherche Robert-Sauvé en Santé Et en Sécurité du Travail (IRSST), Montréal, Québec, Canada.

In recyclable waste management facilities, several contaminants, mainly bioaerosols and microorganisms, can be released and cause potential adverse health effects. Given that microbial volatile organic compounds (mVOCs) are metabolites developed by molds and since they can be considered as potential biomarkers of mold exposure, their concentrations in ambient air were monitored at a recyclable waste sorting plant (WSP) and a university campus (UC) serving as control environment for comparison. A recently developed analytical method was used for the detection of 21 selected mVOCs in real conditions.

ZIC1 is a context-dependent medulloblastoma driver in the rhombic lip.

Nat Genet

January 2025

Department of Laboratory Medicine and Pathobiology, University of Toronto, Toronto, Ontario, Canada.

Transcription factors are frequent cancer driver genes, exhibiting noted specificity based on the precise cell of origin. We demonstrate that ZIC1 exhibits loss-of-function (LOF) somatic events in group 4 (G4) medulloblastoma through recurrent point mutations, subchromosomal deletions and mono-allelic epigenetic repression (60% of G4 medulloblastoma). In contrast, highly similar SHH medulloblastoma exhibits distinct and diametrically opposed gain-of-function mutations and copy number gains (20% of SHH medulloblastoma).
