Article Abstract

Structure determination of G-protein-coupled receptors and other applications, such as nuclear magnetic resonance studies, require milligram quantities of purified, functional receptor protein on a regular basis. We present an overview on expression and purification studies with a receptor for neurotensin. Functional expression in Escherichia coli and an automated two-column purification routine allow ongoing crystallization experiments and studies on receptor-bound ligands.

Temporal transcriptomics reveal crucial networks underlying jasmonate-mediated diurnal floret opening and closure in rice.

Diurnal floret opening and closure (DFOC) is essential for rice reproductive development and hybrid breeding, yet transcriptional dynamics and underlying regulatory networks remain poorly characterized. Here, we conducted high-temporal-resolution transcriptomic analyses of lodicules to dissect DFOC regulatory networks in two japonica rice cultivars. Analysis of differentially expressed genes (DEGs) uncovered core genes shared by both cultivars, primarily associated with jasmonic acid (JA) signaling and cell wall remodeling.

Structural biology is fundamental to understanding the molecular basis of biological processes. While machine learning-based protein structure prediction has advanced considerably, experimentally determined structures remain indispensable for guiding structure-function analyses and for improving predictive modeling. However, experimental studies of protein complexes continue to pose challenges, particularly due to the necessity of high protein concentrations and purity for downstream analyses such as cryogenic electron microscopy.

Urinary tract infections (UTIs) are among the most common bacterial infections and are increasingly complicated by multidrug resistance (MDR). While Escherichia coli is frequently implicated, the contribution of broader microbial communities remains less understood. Here, we integrate metatranscriptomic sequencing with genome-scale metabolic modeling to characterize active metabolic functions of patient-specific urinary microbiomes during acute UTI.

High-Level Soluble Expression of Recombinant Human Bone Morphogenetic Protein-2 in .

Human Bone Morphogenetic Protein-2 (hBMP-2) serves as a critical regulator in bone and cartilage formation; however, its industrial application is hindered by its inherent tendency to form inclusion bodies in prokaryotic expression systems. To address this issue, we established a recombinant hBMP-2 (rhBMP-2) expression system using the pCold II plasmid and the SHuffle T7 strain. We explored several strategies to enhance the solubility of rhBMP-2, including coexpression with molecular chaperones, vesicle-mediated secretory expression, fusion expression with synthetic intrinsically disordered proteins (SynIDPs), and fusion expression with small-molecule peptide tags.

Flammulina velutipes is a major edible fungus with abundant yield and mature industrial production technology. Its main functional component, Flammulina velutipes polysaccharide, has huge development and utilization value. In light of the current uncertainty regarding the mechanisms by which Flammulina velutipes polysaccharides prevent colonic cell pyroptosis, the mechanisms of ultrasound-extracted Flammulina velutipes polysaccharide (FVPU2) in inhibiting colonic cell pyroptosis in mice were investigated, and compared with Flammulina velutipes polysaccharide extracted via hot water extraction (FVPH2).
