Helicobacter pylori‐Induced Persistent IGF2BP1 Activation Promotes Ferroptosis Resistance in Gastric Tumorigenesis

open access: yesAdvanced Science, EarlyView.
Helicobacter pylori infection induces sustained upregulation of the RNA‐binding protein IGF2BP1 in gastric epithelial cells, establishing a persistent epitranscriptomic program. IGF2BP1 stabilizes SLC7A11 mRNA in an m6A‐dependent manner to suppress ferroptosis and promote epithelial survival under oxidative stress. Pharmacological inhibition of IGF2BP1

Raman Analysis of RNA Nucleotide Strands From SARS‐CoV‐2 Variants and Subvariants: A Step Forward in the Definition of “Raman Genome”

open access: yesAdvanced Science, EarlyView.
Main Raman signals in RNA, related to helical backbone, ribofuranose ring, and nitrogenous bases, are affected by secondary structures that cause hyperchromic effects and significantly alter the Raman intensity. ABSTRACT Raman spectra of RNA nucleotide strands extracted from 20 SARS‐CoV‐2 strains, including the original Japanese isolate, Alpha, Beta ...

A Metabolic‐Epigenetic Axis of AARS1/IGF2BP3‐K280 Lactylation Sustains Endometrial Cancer Stemness and Recurrence

open access: yesAdvanced Science, EarlyView.
Lactate‐driven endometrial cancer relapse is mediated by enzymatic protein modification. Elevated lactate levels activate AARS1, which catalyzes K280 lactylation of IGF2BP3, therefore stabilizing HMGA2 mRNA and promoting tumor stemness and recurrence.

CHD8‐Dependent Chromatin Licensing Sustains Trophoblast Stem Cell Transcriptional Programs

open access: yesAdvanced Science, EarlyView.
In this study, Huang et al., identify chromatin remodeler CHD8 as an essential factor in TSC maintenance and placental development. CHD8‐dependent chromatin accessibility supports the occupancy of key trophoblast TFs and is coupled to KMT2A‐associated H3K4me3 deposition at TSC stem and cell cycle genes, providing a permissive chromatin environment for ...

Acid‐Responsive Nanobot‐Integrated Core‐Shell Microneedles Reprogram the Degenerative Annulus Fibrosus Microenvironment Through Epigenetic Suppression of Ferroptosis

open access: yesAdvanced Science, EarlyView.
An acid‐responsive core‐shell microneedle system normalizes the degenerative annulus fibrosus microenvironment by consuming pathological H+, generating O2, and providing NIR‐amplified redox buffering. Mechanistically, it epigenetically suppresses ferroptosis via DNMT3A‐dependent methylation of the ATF3 promoter, relieving ATF3‐mediated repression of ...

Modulation of the TGF‐β/Smad Signaling Pathway by a Bioactive Oxidized Polygonati Rhizoma Polysaccharide Crosslinked Chitosan Hydrogel as Therapeutic Carrier for Parkinson's Disease Treatment

open access: yesAdvanced Science, EarlyView.
An injectable, self‐healing COPRP hydrogel integrates structurally defined oxidized Polygonati rhizoma polysaccharide with carboxymethyl chitosan through dynamic Schiff‐base crosslinking. The bioactive matrix scavenges reactive oxygen species, suppresses neuroinflammation, protects dopaminergic neurons, and supports sustained levodopa release.

NS1‐Induced PARP1 Phase Transitions Prolongs Host Transcriptional Pausing to Promote Influenza A Virus Replication

open access: yesAdvanced Science, EarlyView.
After IAV infection, NS1 induces PARP1 phase transition, reducing molecular mobility in condensates, prolonging host transcriptional pause, aiding RdRp cap snatching, and promoting viral transcription. ABSTRACT Influenza A virus (IAV) commandeers host transcriptional machinery to replicate, but mechanisms remain elusive.
