Genome transcription/translation of segmented, negative-strand RNA viruses

open access: yes, 2011
The requirements for alignment of capped RNA leader sequences along the viral genome during influenza transcription initiation (“cap-snatching”) have long been an enigma.

Artery‐on‐Chip Demonstrates Mechanical and Functional Features of Healthy and Diseased Living Smooth Muscle Tissue

open access: yesAdvanced Functional Materials, EarlyView.
This article details the development of an artery‐on‐chip platform for in vitro arterial disease modeling and therapeutic discovery. It describes the fabrication of a fibrin biomaterial scaffold seeded with iPSC‐derived smooth muscle and endothelial cells, mimicking native artery properties. Two genetic disease models showcase the platform's ability to

Circular RNAs Biogenesis, Regulatory Mechanisms, and Their Future Applications in Laboratory Medicine [PDF]

open access: yesJournal of Basic Research in Medical Sciences
Introduction: Circular RNAs (circRNAs)- once considered splicing artifacts- are covalently closed RNA molecules generated through back-splicing, lacking 5′ caps and 3′ poly(A) tails, which confers them with remarkable stability.

Ap4A-RNA in IgE activated mast cells

open access: yes, 2021
Mast cells are tissue resident members of the immune system. They have a wide range of functions and receptors including the FcεRI receptor, which gets activated by binding to IgE bound to an antigen.

A Fully Human Engineered Bone Niche With Endogenous Osteoclastogenesis Reveals Osteoclast‐Dependent Osteomimicry in Prostate Cancer Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
A human 3D bone niche integrating osteoblasts and osteoclasts enables co‐culture with prostate cancer cell lines and patient‐derived organoids. The engineered niche (i) models aspects of reciprocal phenotypic regulation between osteoblasts and cancer cells, (ii) captures osteoclast‐enhanced osteomimicry in tumor cells, and (iii) establishes a ...

New types of RNA non-canonical caps and their degradation by NudiX enzymes [PDF]

open access: yes
(English) Currently, more than 170 RNA modifications are known in both prokaryotes and eukaryotes, but the role of many of them is not well understood.

Pattern recognition and signaling mechanisms of RIG-I and MDA5

open access: yesFrontiers in Immunology, 2014
Most organisms rely on innate immune receptors to recognize conserved molecular structures from invading microbes. Two essential innate immune receptors, RIG-I and MDA5, detect viral double-stranded RNA in the cytoplasm.

Conversion of a DNA ligase into an RNA capping enzyme [PDF]

open access: yesNucleic Acids Research, 1999
In eukaryotes, newly synthesised mRNA is 'capped' by the addition of GMP to the 5" end by RNA capping enzymes. Recent structural studies have shown that RNA capping enzymes and DNA ligases have similar protein folds, suggesting a conserved catalytic mechanism.

Immunoinflammatory Mechanisms and Biocompatibility of Bioactive Dental Biomaterials: From Fundamental Insights to Clinical Translation

open access: yesAdvanced Healthcare Materials, EarlyView.
Surface‐host dialogue at the implant interface governs biological fate and osseointegration. Surface physicochemical properties of titanium (Ti) dental implants, including microgrooves, nanopatterns, nanotopography, roughness, and wettability, modulate the initial adsorption of proteins and the formation of a dynamic biointerface.
