Cobalt Single‐Atom Nanozyme for Enhanced Intestinal Radioprotection and Tumor Radiosensitization via Bidirectional ROS Modulation

Advanced Science, EarlyView.
Orally administered, pH‐responsive Co‐SAN exerts dual functions: in the alkaline intestinal milieu, it scavenges reactive oxygen species (ROS) and suppresses the PI3K/AKT pathway and NETs formation, thus providing radioprotection; whereas in the acidic tumor microenvironment, it generates ROS and alleviates hypoxia, thereby enhancing radiosensitization.

Cholangiocyte organoids for disease, cancer, and regenerative medicine

European Journal of Cell Biology
The biliary tract is a ductal network comprising the intrahepatic (IHBDs) and extrahepatic bile duct (EHBDs). Biliary duct disorders include cholangitis, neoplasms, and injury. However, the underlying mechanisms are not fully understood.

Common features between neoplastic and preneoplastic lesions of the biliary tract and the pancreas [PDF]

, 2019
The bile duct system and pancreas show many similarities due to their anatomical proximity and common embryological origin. Consequently, preneoplastic and neoplastic lesions of the bile duct and pancreas share analogies in terms of molecular ...

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

Advanced 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.

Biliary tract neoplasms.

Tropical gastroenterology : official journal of the Digestive Diseases Foundation, 1998
From January 1993 to December 1995, complete records of patients with biliary neoplasms were analysed. A total of 124 patients were registered. Majority of patients were in the age range of 40-60 years (median 54 years). There were 38 males and 86 females. Histopathologically, adenocarcinoma was the commonest type (59%).
