Palladium‐Catalyzed Aryloxycarbonylayion of Aryl Bromides with Phenols Using Inositol Hexaformate as an Efficient CO Source

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
We designed a novel carbon monoxide surrogate inositol hexaformate (HFI) and applied it to the palladium‐catalyzed aryloxycarbonylation of aryl bromides with phenols. HFI liberates six molecules of carbon monoxide, exhibiting a significantly higher efficiency and CO capacity than the conventional formate surrogates.

Multi‐Omics Reveal the Dysregulated Gut‐Joint Axis in Knee Synovitis: Data from Two Osteoarthritis Studies in China

open access: yesAdvanced Science, EarlyView.
The “gut‐joint axis” in knee synovitis is uncovered. Integrated multi‐omics studies are conducted in two independent osteoarthritis cohorts. Synovitis is characterized an increased F/B ratio, as well as alterations of 3‐HIA, geranic acid, and TWEAK. Upregulated TWEAK receptor is found in high‐grade synovitis, and inversely correlated with lower TWEAK ...

Small Nucleolar RNA Snord17 Promotes Self‐Renewal of Intestinal Stem Cells through Yy2 mRNA Export and Tead4 Activation

open access: yesAdvanced Science, EarlyView.
Snord17, through interaction with Thoc3, promotes nuclear export and translation of Yy2 mRNA in Snord17+/+ ISCs. The Yy2 protein subsequently binds the Tead4 promoter to promote its transcription, activating Hippo signaling, which is essential for ISC maintenance.
