Nano‐Enabled Systemic Delivery of STING Agonist by Engineered Silicasome for Potent Antitumor Immunotherapy

Advanced Science, EarlyView.
Engineered mesoporous silica nanoparticles (Silicasomes) enable systemic delivery of the STING agonist ADU‐S100, overcoming the instability and toxicity that limit cyclic dinucleotides to local administration. By enhancing tumor accumulation, activating systemic antitumor immunity, and remodeling the tumor immune microenvironment, these nanoparticles ...

Nucleolar stress induces nucleolar stress body formation via the NOSR-1/NUMR-1 axis in Caenorhabditis elegans

Nature Communications
Environmental stimuli not only alter gene expression profiles but also induce structural changes in cells. How distinct nuclear bodies respond to cellular stress is poorly understood.

Defining the impact of rRNA processing on nucleolar organization and function

SUMMARY The eukaryotic nucleolus is a highly organized, multilayered structure essential for ribosomal RNA (rRNA) processing and ribosome assembly. However, how the sequential steps of rRNA maturation, particularly the series of endonucleolytic cleavages, contribute to maintaining nucleolar architecture remains poorly understood.

Plant‐Derived Melatonin Inhibits Bacterial Virulence via CpxA/R Two‐Component System

Advanced Science, EarlyView.
Plant‐derived melatonin is sensed by CpxAE48/T51, which inhibits the phosphorylation cascade transmission from CpxAH240 to CpxRD52, resulting in the inhibition of DNA‐binding capacity of CpxR and subsequent T3SS genes expression in Pst DC3000. ABSTRACT In defending against pathogens, plants deploy diverse secondary metabolites and signaling molecules ...

Programmable RNA N6,2´‐O‐Dimethyladenosine Editing

Advanced Science, EarlyView.
ABSTRACT N6,2’‐O‐dimethyladenosine (m6Am) is a prevalent RNA modification located at the first transcribed nucleotide adjacent to the 5′ cap of mRNAs, where it has been implicated in gene regulation. However, the lack of methods for precise, transcript‐specific manipulation of m6Am has limited its functional dissection.
