Chemoselective Metabolomics via a Modular Reactivity‐Encoding Platform

open access: yesAdvanced Science, EarlyView.
Conventional LC–MS underrepresents numerous metabolites due to heterogeneous ionization efficiencies and matrix interference. Here, we introduce a modular reactivity‐encoding platform (MREP) comprising four alkyne‐tagged probes that selectively derivatize key functional groups, followed by unified click‐chemistry capture to eliminate matrix components ...

Nuclear Receptors as Targets for Drug Development: Regulation of Cholesterol and Bile Acid Metabolism by Nuclear Receptors

open access: yesJournal of Pharmacological Sciences, 2005
Nuclear receptors are ligand-dependent transcription factors that recently have been shown to play important roles in the metabolism of cholesterol and bile acids.

Review of Gastrointestinal Capsule Robots: Materials, Actuation, Diagnostics, and Therapeutics

open access: yesAdvanced Science, EarlyView.
This review examines gastrointestinal capsule robots through a systems engineering lens, covering shell materials, actuation and localization strategies, diagnostic modalities, therapeutic interventions, and commercialization status. By mapping the complete technological chain from fabrication to clinical deployment, this work identifies critical gaps ...

The effect of liver warm ischaemia reperfusion injury and modulation on bile composition evaluated by magnetic resonance spectroscopy [PDF]

open access: yes, 2015
Orthotopic liver transplantation has become the preferred treatment for a variety of end-stage liver disease. As competency and survival rates increase, so does increasing demand, which puts greater strain on a static donor pool.

Bile acid analysis in human disorders of bile acid biosynthesis

open access: yes, 2017
Bile acids facilitate the absorption of lipids in the gut, but are also needed to maintain cholesterol homeostasis, induce bile flow, excrete toxic substances and regulate energy metabolism by acting as signaling molecules.

Alterations in bile acid kinetics after bariatric surgery in patients with obesity with or without type 2 diabetesResearch in context

open access: yesEBioMedicine
Summary: Background: Bariatric surgery is an effective treatment option for obesity and provides long-term weight loss and positive effects on metabolism, but the underlying mechanisms are poorly understood. Alterations in bile acid metabolism have been

Ahcy Acts as an Effector of Hnf4a‐Driven Super‐Enhancer Activation to Alleviate MASLD During Intermittent Fasting

open access: yesAdvanced Science, EarlyView.
Our study identifies an Hnf4a‐driven super‐enhancer of hepatic Ahcy that mediates the protective effects of intermittent fasting against MASLD. Disruption of the Ahcy super‐enhancer reduces Ahcy expression and exacerbates lipid accumulation. This pathway prevents aberrant promoter hypermethylation by maintaining the SAM/SAH balance, as exemplified by ...

Targeting Tex10 Overcomes Oxaliplatin Resistance by Competitively Disrupting the Non‐Canonical BAF Complex in Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
This study reveals that Tex10 drives oxaliplatin resistance in colorectal cancer by competitively binding BRD9 to disrupt the ncBAF complex, thereby suppressing AMBRA1 transcription and ULK1‐mediated autophagy. Gemcitabine is identified as a direct Tex10 inhibitor that restores autophagy and overcomes resistance.

The CXCL5/CXCR2 Axis Attenuates Ferroptosis in Intrahepatic Cholangiocarcinoma Through the Positive Feedback Loop Between PTGS2 Transcriptional Activation and Neutrophil Recruitment

open access: yesAdvanced Science, EarlyView.
The CXCL5/CXCR2 axis directly inhibits ferroptosis in ICC cells by activating the NF‐κB/PTGS2 pathway. Meanwhile, the CXCL5/CXCR2 axis recruits N2 TANs, and the activated PTGS2 promotes the secretion of TNF‐α from the recruited N2 TANs via the CCL2/CCL7/CCR2 pathway, thereby activating the NF‐κB/PTGS2 axis and forming a positive feedback loop, which ...
