Cancer Manipulates Adjacent Adipose Tissue to Exploit Fatty Acids via HIF‐1α/CCL2/PPARα Axis: A Metabolic Circuit to Support Tumor Progression

open access: yesAdvanced Science, EarlyView.
Cancer cells drive adjacent adipose tissue to release fatty acids by secreting CCL2, which activates PPARα‐dependent lipolysis. The resulting fatty acid influx amplifies HIF‐1α/CCL2 signaling, establishing a positive feedback loop that fuels tumor growth.

Medicago Sativa L. Saponin‐Driven Lactobacillus Intestinalis Restores Intestinal Stemness in Naturally Aged Mice via the Bile Acid‐FXR‐Wnt Signaling Axis

open access: yesAdvanced Science, EarlyView.
This study examines the mechanism by which alfalfa saponin (AS) regulates intestinal stemness via modulation of the gut microbiota. The results indicate that AS significantly increases the abundance of Lactobacillus intestinalis, which subsequently activates Wnt signaling via bile acid metabolism and enhances intestinal stemness. These findings provide

An Engineered Solidified Peptide Hemocyte Sponge as Nanomotor Storage to Combat Bacterial Colitis

open access: yesAdvanced Science, EarlyView.
Peptides immobilized via nickel coordination can stabilize the framework structure. Following coating with red blood cell membranes, these constructs are capable of continuously sequestering endotoxins and mitigating colonic pathogenic damage by alleviating bacterial‐induced ferroptosis.

Lactobacillus Salivarius‐Derived Indole‐3‐Acetic Acid Promotes AHR‐PARP1 Axis‐Mediated DNA Repair to Mitigate Intestinal Aging

open access: yesAdvanced Science, EarlyView.
Indole‐3‐acetic acid (IAA) acting as one of the aryl hydrocarbon receptor (AHR) endogenous ligands is identified to be derived from Lactobacillus salivarius via its catalytic enzyme (ALDH) rather than host cells. Lactobacillus salivarius and IAA supplementation effectively mitigate intestinal aging by facilitating AHR‐poly (ADP‐ribose) polymerase 1 ...

Mechanisms of Direct Electron Transfer Governed by Redox‐Active Conductive Carrier with Superior Wettability in Anaerobic Biofilms

open access: yesAdvanced Science, EarlyView.
A redox‐active conductive carrier of tannic acid‐modified iron‐biochar with superior wettability is demonstrated to regulate direct electron transfer at the anaerobic biofilm‐carrier interface by enhancing the cytochrome c‐mediated pathway. For the first time, integrated evidence from spectroscopy, electrochemical analyses, and metatranscriptomics ...
