Two intracellular and cell type-specific bacterial symbionts in the placozoan Trichoplax H2

, 2019
Placozoa is an enigmatic phylum of simple, microscopic, marine metazoans(1,2). Although intracellular bacteria have been found in all members of this phylum, almost nothing is known about their identity, location and interactions with their host(3-6). We

Hypoglycemia Induces Diabetic Macrovascular Endothelial Dysfunction via Endothelial Cell PANoptosis, Macrophage Polarization, and VSMC Fibrosis

Advanced Science, EarlyView.
This study investigates hypoglycemia‐induced diabetic macrovascular endothelial dysfunction. It reveals that hypoglycemia triggers ZBP1‐dependent PANoptosis of endothelial cells, proinflammatory polarization of macrophages, and fibrosis of vascular smooth muscle cells (VSMCs) in diabetic mice.

Chronic Psychological Stress Induces Cardiomyocyte Hypertrophy Through Corticosterone‐Glucocorticoid Receptor‐LAMA5 Axis

Advanced Science, EarlyView.
In vivo experiments suggest that cardiomyocyte hypertrophy is an early manifestation of cardiac pathological changes induced by chronic psychological stress. In vivo and in vitro experiments suggest that the corticosterone‐glucocorticoid receptor‐LAMA5 axis mediates cardiomyocyte hypertrophy induced by chronic psychological stress. The clinical results

Evolution of protein-coupled RNA dynamics during hierarchical assembly of ribosomal complexes

Nature Communications, 2017
Ribosomes assemble through the hierarchical addition of proteins to a ribosomal RNA scaffold. Here the authors use three-color single-molecule FRET to show how the dynamics of the rRNA dictate the order in which multiple proteins assemble on the 5 ...

The unseen world: environmental microbial sequencing and identification methods for ecologists [PDF]

, 2014
Archaea, bacteria, microeukaryotes, and the viruses that infect them (collectively “microorganisms”) are foundational components of all ecosystems, inhabiting almost every imaginable environment and comprising the majority of the planet’s organismal and ...

Nicotine Reprograms Aging‐Related Metabolism and Protects Against Motor Decline in Mice

Advanced Science, EarlyView.
Long‐term oral nicotine intake protects against age‐related motor decline in mice without eliciting systemic toxicity. Integrated multi‐organ metabolomic profiling and longitudinal gut microbiota analyses reveal that nicotine induces coordinated remodeling of glycolipid and sphingolipid metabolism, enhances NAD⁺ bioavailability, and suppresses ceramide

Updating the 97% identity threshold for 16S ribosomal RNA OTUs [PDF]

Bioinformatics, 2017
AbstractThe 16S ribosomal RNA (rRNA) gene is widely used to survey microbial communities. Sequences are often clustered into Operational Taxonomic Units (OTUs) as proxies for species. The canonical clustering threshold is 97% identity, which was proposed in 1994 when few 16S rRNA sequences were available, motivating a reassessment on current data ...

Engineered Foxp1high Exosomes Ameliorates Systemic Lupus Erythematosus

Advanced Science, EarlyView.
This study presents a dual‐engineering strategy combining mesenchymal stem cell aggregation and Foxp1 overexpression to generate Foxp1high aggregation exosomes with enhanced immunomodulatory properties. These engineered exosomes exhibit immune organ targeting and superior efficacy in systemic lupus erythematosus treatment by promoting Treg ...

Transcriptome‐Wide Association Uncovers LncRNAs Controlling Seed Weight in Soybean

Advanced Science, EarlyView.
This study employs transcriptome‐wide association studies (TWAS) to identify 201 long non‐coding RNAs (lncRNAs) associated with seed weight. Expression quantitative trait locus (eQTL) analysis reveals dynamic and static regulatory variants controlling lncRNA expression across development.

Tracing and Capturing the Epiblast Pluripotency of Sheep Preimplantation Embryos

Advanced Science, EarlyView.
This study performs a comprehensive single‐cell transcriptome analysis of sheep embryos from embryonic (E) day 1 to E14 to elucidate the mechanism of early lineage specification and the pluripotency changes (naïve, formative, and primed) of epiblast.
