Endoscopic ischemic polypectomy for small intestinal polyps in a 7‐year‐old girl with juvenile polyposis syndrome

open access: hybridJPGN Reports, EarlyView.
Abstract This is the first report of endoscopic ischemic polypectomy (EIP) for small intestinal polyps in a pediatric patient with juvenile polyposis syndrome (JPS). A 7‐year‐old girl underwent double‐balloon enteroscopy, during which 17 pedunculated polyps were treated using the crossed‐clip strangulation method without complications. Ten‐month follow‐

Context‐Dependent Role of GDF15: GDF15+ Tumor‐Associated Macrophages Suppress OSCC Progression by Enhancing Phagocytosis

open access: yesAdvanced Science, EarlyView.
This study identifies GDF15+ TAMs as a cell subset mediating tumor regression after immunotherapy. Macrophage‐intrinsic GDF15 enhances phagocytosis and antigen cross‐presentation to CD8+ T cells through the NF‐κB signaling pathway, thereby inhibiting tumor progression.

A Soft Matrix Microenvironment Promotes Laterally Spreading Tumors via Oxidative Phosphorylation‐Dependent Cell Adhesion

open access: yesAdvanced Science, EarlyView.
Laterally spreading tumors (LSTs) are precancerous colorectal lesions characterized by a flat morphology. This study reveals a mechanochemical pathway through which a soft matrix microenvironment diminishes spatial constraints in intestinal adenomas. This process promotes deficiencies in tight junction proteins, mediated by the mechanoreceptor ADORA2B ...
