DENTA: A Dual Enzymatic Nanoagent for Self‐Activating Tooth Whitening and Biofilm Disruption

open access: yesAdvanced Functional Materials, EarlyView.
The nanoapatite with dual enzymes (DENTA) accumulates in dentinal tubules, reducing hypersensitivity caused by dental nerve exposure and facilitating continuous ROS generation through salivary glucose for effective, long‐term whitening. The dentin structures remain non‐destructive due to the low concentration of ROS, demonstrating excellent cell ...

The role of RNA helicases in aging and lifespan regulation

open access: yesTranslational Medicine of Aging, 2017
RNA helicases are members of a large family of enzymes that function in unwinding RNA duplexes and modulating interactions between RNAs and proteins. RNA helicases participate in numerous cellular processes, including transcription, translation, mRNA ...

Diminished nuclear RNA decay upon Salmonella infection upregulates antibacterial noncoding RNAs

open access: yesEMBO Journal, 2018
Cytoplasmic mRNA degradation controls gene expression to help eliminate pathogens during infection. However, it has remained unclear whether such regulation also extends to nuclear RNA decay.

CRISPR/Cas9‐Assisted Microrobots for Fast and Ultrasensitive “On‐The‐Fly” Next‐Generation DNA Detection

open access: yesAdvanced Functional Materials, EarlyView.
This work presents self‐propelled CRISPR/Cas9‐functionalized Au–MRs for rapid, amplification‐free, “on‐the‐fly” DNA detection. By harnessing motion‐assisted signal recovery, the platform achieved the limit of detection in low fM DNA concentrations, enabling detection across a wide dynamic range within only 5 min, which is significantly faster than any ...

Dynamics and clinical relevance of maternal mRNA clearance during the oocyte-to-embryo transition in humans

open access: yesNature Communications, 2020
How maternal RNA clearance is regulated in human preimplantation embryos is unclear. Here, the authors show there is a potential correlation between maternal mRNA decay defects and early developmental arrest from in vitro fertilized human embryos ...

Position of Premature Termination Codons Determines Susceptibility of hERG Mutations to Nonsense-Mediated mRNA Decay in Long QT Syndrome

open access: yes, 2014
The degradation of human ether-a-go-go-related gene (hERG, KCNH2) transcripts containing premature termination codon (PTC)mutations by nonsense-mediatedmRNA decay (NMD) is an importantmechanismof long QT syndrome type 2 (LQT2).

Laser‐Based Sculpturing of Embedded Ultrathin Metal‐Oxide Nanopores for Enhanced Biomolecular Sensing

open access: yesAdvanced Functional Materials, EarlyView.
Controlled laser‐drilling of embedded HfO2 membranes creates three layer nanopores with Gaussian‐shaped cavities sculptured in the supporting layers. These embedded solid‐state nanopores slow DNA translocation by 12‐fold compared to SiNx pores, enabling high‐resolution, label‐free detection of short DNAs, RNAs, and proteins.

An HIV feedback resistor: auto-regulatory circuit deactivator and noise buffer. [PDF]

open access: yes, 2006
Animal viruses (e.g., lentiviruses and herpesviruses) use transcriptional positive feedback (i.e., transactivation) to regulate their gene expression.
