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

Gentamicin‐Loaded Carbonate Apatite with Dual Antibacterial and Osteogenic Functions for Combating Surgical Site Infections

Advanced Healthcare Materials, EarlyView.
A bone substitute with gentamicin physically precipitated onto the surface of carbonate apatite exhibits prompt drug release, high bactericidal activity, and osteogenic capacity. Efficient antibacterial activity mitigates early postoperative neutrophil accumulation, the status of which may serve as a potential parameter for evaluating the antibacterial

The Beak of Eukaryotic Ribosomes: Life, Work and Miracles

Biomolecules
Ribosomes are not totally globular machines. Instead, they comprise prominent structural protrusions and a myriad of tentacle-like projections, which are frequently made up of ribosomal RNA expansion segments and N- or C-terminal extensions of ribosomal ...

Exploring Functionally Enhanced BLP‐Trained Macrophage Subpopulations in S. Aureus Infection: Underlying Mechanisms and Therapeutic Significance

Advanced Science, EarlyView.
BLP‐trained macrophages show augmented resistance to infection, but their mechanisms remain unclear. scRNA‐seq identified 13 BMDM subsets, with two novel anti‐inflammatory/antibacterial subpopulations (C5/C7) emerging post‐BLP training. BLP training activates NRF2, attenuates oxidative stress/ferroptosis, and boosts glycolysis/OXPHOS. Adoptive transfer

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 ...

DKK3 Initially Preserves Acinar Integrity Through MEK‐Fos Signaling, but Later Switches to an Oncogenic Role in Pancreatic Cancer

Advanced Science, EarlyView.
In pancreatic cancer, the protein DKK3 is found to play a complex role: it initially slows early tumor growth but later promotes tumor aggressiveness. DKK3 expression evolves during progression and drives cancer severity by orchestrating cellular and molecular signaling pathways.

Metformin Restores Mitochondrial Function and Neurogenesis in POLG Patient‐Derived Brain Organoids

Advanced Science, EarlyView.
Patient‐derived POLG‐mutant cortical organoids reveal neuronal subtype‐specific mitochondrial and synaptic defects, with dopaminergic neurons most affected. Metformin treatment restores neuronal identity, mitochondrial function, and excitability, increased mtDNA maintenance, and reprogrammed metabolism via TCA and redox pathways.

Psychrobacter sanguinis Wound Infection Associated with Marine Environment Exposure, Washington, USA

Emerging Infectious Diseases, 2018
We report a 26-year-old man with Psychrobacter sanguinis cellulitis of a wound sustained during ocean fishing in Washington, USA, in 2017. Psychrobacter spp. are opportunistic pathogens found in a wide range of environments. Clinicians should be aware of

CircPVT1 Promotes Lung Metastasis and Tumor Progression in Renal Cell Carcinoma by Encoding the cP104aa Peptide and Targeting EIF4A3

Advanced Science, EarlyView.
This study reveals that circPVT1 promotes the renal cell carcinoma lung metastasis and tumor progression through encoding the cP104aa peptide and directly binds with EIF4A3, which jointly regulates the target gene c‐MYC. Abstract Circular RNA (circRNA) plays a pivotal role in the pathogenesis of renal cell carcinoma (RCC).

PHR‐Mediated Pi Starvation Response Mobile Messenger RNAs Represent Noncoding Transcripts in Recipient Tissues

Advanced Science, EarlyView.
Mobile messenger RNAs (mRNAs) can travel long distances, serving as systemic signals that participate in plant growth and stress acclimation. This work determines that PHR proteins mediate the Pi starvation response (PSR)‐specific long‐distance transport of mRNAs and that these PSR‐specific mobile mRNAs represent noncoding transcripts in recipient ...
