Processing of ribosomal precursor RNAs in Physarum polycephalum

open access: yesNucleic Acids Research, 1980
The processing of intermediates of Physarum rRNA has been investigated using two cloned rDNA restriction fragments as sequence specific probes. The size of the largest stable pre-rRNA detected is 11.8 Kb, as determined by denaturing gel electrophoresis.

4D Mapping of ZIF Biocomposites for High Protein Loading and Tunable Release Profiles

open access: yesAdvanced Functional Materials, EarlyView.
Systematic four‐dimensional mapping of zeolitic imidazolate framework biocomposites reveals how precursor ratios, total concentration, and washing define crystalline phase, protein loading, and release kinetics. This comprehensive study identifies conditions yielding record loading (∼85%) and precise phase–property correlations.

Precursor-specific nucleotide sequences can govern RNA folding

open access: yesCell, 1979
An immediate precursor of 5S ribosomal RNA (rRNA) from Bacillus subtilis has 21 and 42 nucleotide precursor-specific segments associated with its 5' and 3' termini, respectively. On the basis of its nucleotide sequence, predicted secondary structure and location in the rRNA transcriptional unit, the 3' precursor element apparently functions during the ...

Oral Dosed Organo‐Silica Nanoparticles Restore Glucose Homeostasis and β‐Cell Function in Diabetes Rats

open access: yesAdvanced Functional Materials, EarlyView.
An oral nanoplatform, MOP@T@D, which can maintain glucose homeostasis and restore islet β cells in diabetic rats is developed. It achieves efficient intestinal absorption and liver‐targeted delivery. The nanoparticle disintegrates only in response to hyperglycemia to release insulin on demand and provides antioxidant protection through selenoprotein ...

Synthetic Nanobiology Actuated Lipometabolic Cell Factory for Autologous Tumor Immunotherapy

open access: yesAdvanced Functional Materials, EarlyView.
FA plays a crucial role in the interaction between tumor cells and the tumor microenvironment, especially for the immune response. A biocatalytic immunoenhancement strategy is developed to boost antitumor immunity by FA metabolic orientation to ceramide. Through the design of this delicate catalytic immunoenhancement strategy, the synthetic nanobiology

Proteins, Processing, and Properties of Adhesive Fluid Condensates Purified from Mussels

open access: yesAdvanced Functional Materials, EarlyView.
Mussels exhibit an unmatched proficiency for adhering to wet surfaces in salty environments—a remarkable ability that could inspire new biomedical and technical glues. The fluid protein condensates used to form the underwater mussel glue are extracted, reconstituted and characterized with advanced spectroscopy and nanomechanical analysis, revealing ...

A Polyadenylation-Dependent 3′ End Maturation Pathway Is Required for the Synthesis of the Human Telomerase RNA

open access: yesCell Reports, 2015
Telomere maintenance by the telomerase reverse transcriptase requires a noncoding RNA subunit that acts as a template for the synthesis of telomeric repeats.
