Proteomic portraits reveal evolutionarily conserved and divergent responses to spinal cord injury.

Mol Cell Proteomics 2021 Jun 12:100096. Epub 2021 Jun 12.

Division of Neurosurgery, University of British Columbia, Vancouver, BC, Canada.

Despite the emergence of promising therapeutic approaches in preclinical studies, the failure of large-scale clinical trials leaves clinicians without effective treatments for acute spinal cord injury (SCI). These trials are hindered by their reliance on detailed neurological examinations to establish outcomes, which inflate the time and resources required for completion. Moreover, therapeutic development takes place in animal models whose relevance to human injury remains unclear. Read More

Self-Assembled Nanobodies as Selectively Targeted, Nanostructured, and Multivalent Materials.

ACS Appl Mater Interfaces 2021 Jun 15. Epub 2021 Jun 15.

Laboratory for Environmental and Life Sciences, University of Nova Gorica Nova Gorica 5000, Slovenia.

Nanobodies represent valuable tools in advanced therapeutic strategies but their small size (∼2.5 × ∼ 4 nm) and limited valence for interactions might pose restrictions for applications, especially regarding their modest capacity for multivalent and cooperative interaction. In this work, modular protein constructs have been designed, in which nanobodies are fused to protein domains to provide further functionalities and to favor oligomerization into stable self-assembled nanoparticles.

TIMEOR: a web-based tool to uncover temporal regulatory mechanisms from multi-omics data.

Nucleic Acids Res 2021 Jun 14. Epub 2021 Jun 14.

Center for Computational and Molecular Biology, Brown University, Providence, RI 02912, USA.

Uncovering how transcription factors regulate their targets at DNA, RNA and protein levels over time is critical to define gene regulatory networks (GRNs) and assign mechanisms in normal and diseased states. RNA-seq is a standard method measuring gene regulation using an established set of analysis stages. However, none of the currently available pipeline methods for interpreting ordered genomic data (in time or space) use time-series models to assign cause and effect relationships within GRNs, are adaptive to diverse experimental designs, or enable user interpretation through a web-based platform.

Wheat ATIs: Characteristics and Role in Human Disease.

Front Nutr 2021 28;8:667370. Epub 2021 May 28.

Laboratory of Food Chemistry, Wageningen University and Research, Wageningen, Netherlands.

Amylase/trypsin-inhibitors (ATIs) comprise about 2-4% of the total wheat grain proteins and may contribute to natural defense against pests and pathogens. However, they are currently among the most widely studied wheat components because of their proposed role in adverse reactions to wheat consumption in humans. ATIs have long been known to contribute to IgE-mediated allergy (notably Bakers' asthma), but interest has increased since 2012 when they were shown to be able to trigger the innate immune system, with attention focused on their role in coeliac disease which affects about 1% of the population and, more recently, in non-coeliac wheat sensitivity which may affect up to 10% of the population.

Carbohydrate-binding module -mannosylation alters binding selectivity to cellulose and lignin.

Chem Sci 2020 Aug 19;11(34):9262-9271. Epub 2020 Aug 19.

Institute of Materia Medica, Chinese Academy of Medical Sciences, Peking Union Medical College Beijing 100050 China

Improved understanding of the effect of protein glycosylation is expected to provide the foundation for the design of protein glycoengineering strategies. In this study, we examine the impact of -glycosylation on the binding selectivity of a model Family 1 carbohydrate-binding module (CBM), which has been shown to be one of the primary sub-domains responsible for non-productive lignin binding in multi-modular cellulases. Specifically, we examine the relationship between glycan structure and the binding specificity of the CBM to cellulose and lignin substrates. Read More

Health and nutrition of loggerhead sea turtles (Caretta caretta) in the southeastern United States.

J Anim Physiol Anim Nutr (Berl) 2021 Jun 13. Epub 2021 Jun 13.

Harbor Branch Oceanographic Institute, Florida Atlantic University, Fort Pierce, Florida, USA.

Loggerhead sea turtles (Caretta caretta) are opportunistic carnivores that feed primarily on benthic invertebrates and fish. Sea turtle rehabilitation requires provision of a species-specific, balanced diet that supplies nutrition similar to that of a wild diet; this can be challenging because free-ranging loggerheads' diets vary depending on their life stage and geographic location, with predominant prey species dictated by local availability. The goal of this study was to better understand the nutritional needs of subadult and adult loggerheads in rehabilitation. Read More
