Cold Orthogonal Translation: A Psychrophilic Pyrrolysyl‐tRNA Synthetase Boosts Genetic Code Expansion in E. coli

open access: yesAdvanced Science, EarlyView.
ABSTRACT Orthogonal translation systems (OTSs) enable site‐specific incorporation of non‐canonical amino acids (ncAAs) and are central to genetic code expansion. Current engineering strategies typically rely on hyperstable aminoacyl tRNA synthetase (aaRS) scaffolds to tolerate destabilizing mutations required for substrate diversification.

TRMT6‐Mediated m1A Modification of CDK9 mRNA Is a Dual‐Pronged Pathogenic Driver for HBV‐Related Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
TRMT6‐mediated m1A modification in CDK9 mRNA enhances its mRNA stability and translation efficiency, thereby increasing the protein levels of CDK9. Upregulated CDK9 promotes the progression of HCC by elevating the levels of oncogenic factors including p‐STAT3, MCL1, and BCL‐2. On the other hand, CDK9 phosphorylates TARDBP at Ser254 to activate HBV core

A double-edged sword in antiviral defence: ATG7 binding dicer to promote virus replication

open access: yesCellular and Molecular Life Sciences
RNA interference (RNAi) and autophagy are two pivotal biological processes that regulate virus replication. This study explored the complex relationship between autophagy and RNAi in controlling influenza virus replication.

Electroacupuncture Improves the Learning and Memory by Modulating Hippocampal Glucose Metabolism through IGF1/IGF1R Signaling in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
Electroacupuncture (EA) ameliorates learning and memory function in 5×FAD mice by regulating the brain glucose metabolic network. This neuroprotective effect is closely related to enhancing neuronal energy utilization via the IGF1/IGF1R signaling pathway.

Studies on influenza A virus PB1-F2 protein

open access: yes, 2011
The influenza A virus genome codes for up to 12 proteins. Segment 2 encodes three proteins, the polymerase subunit PB1, a small protein PB1-F2 and an N-terminally truncated version of PB1 called N40. Different functions have been reported for PB1-F2 such

A Central Somatic Transmission Mediates Proprioceptive Facilitation of Muscle Pain

open access: yesAdvanced Science, EarlyView.
Zhang et al. uncover a novel central mechanism for persistent muscle pain, in which TRPA1 sensitization in MeV proprioceptive neurons enhances somatic secretion. This, in turn, disinhibits descending pain control from neighboring noradrenergic locus coeruleus neurons via local GABAergic circuits, thereby promoting inflammatory muscle pain.

Defective interfering particles of parainfluenza virus subtype 5 and interferon induction

open access: yes, 2015
The innate immune response is the first line of defence against virus infection. Cells contain a diverse array of pathogen recognition receptors (PRRs) that are able to recognise multiple pathogen associated molecular patterns (PAMPS) that present ...

Zinc Exposure Causes Disulfidptosis to Induce Miscarriage by Up‐Regulating GATA1/METTL1/SLC7A11 Axis

open access: yesAdvanced Science, EarlyView.
Zn exposure up‐regulates GATA1, promoting GATA1‐mediated METTL1 and SLC7A11 transcription. It also enhances METTL1‐mediated m7G modification on SLC7A11 mRNA, increasing SLC7A11 mRNA stability. Ultimately, Zn exposure up‐regulates SLC7A11 at both transcriptional and post‐transcriptional levels, causing disulfidptosis. Knockdown of murine Slc7a11, Gata1,

A 3D In Vitro Model of the Human Hepatobiliary Junction

open access: yesAdvanced Science, EarlyView.
A 3D human organoid platform reconstructs the hepatobiliary junction between primary adult hepatocytes and intrahepatic cholangiocytes. These adult hepatobiliary organoids (aHBOs) support directional bile transport from canaliculi to ductule‐like structures, enable quantitative imaging of junction dynamics, and reveal cell‐type‐specific vulnerabilities
