Article Title: Parabacteroides distasonis regulates PPARɑ to alleviate colchicine-induced colonic injury through p-cresol sulfate.
Article Snippet: Colchicine has been extensively utilized for treating gouty arthritis over many years, yet its dose-limiting gastrointestinal toxicity remains a significant clinical challenge.. While diarrhoea and nausea are well recognised, the extent of colchicine-induced occult colonic injury-including its impact on the gut microbiota and mucosal homeostasis-is poorly defined.. This study investigates colchicine-induced colonic injury (e.g., oxidative stress, mitochondrial dysfunction) in vivo and in vitro and also the imbalance of gut microbiota composition in mice.

Article Title: Self-traceable, Self-protective, and self-sufficient combinational catalytic therapy of inflammatory bowel disease by a smart Nanozyme-DNAzyme platform
Article Snippet: DNAzyme-based gene silencing therapies are promising candidates for the treatment of inflammatory bowel disease (IBD).. However, DNAzyme’s unique substrate, structural instability, and conditional catalytic mechanism necessitate delivery systems enabling concurrent integration of precision (gene silencing surveillance), durability (degradation resistance), and efficacy (sustained catalytic output).. Herein, we propose a smart photoacoustic imaging (PAI)-guided nanozyme-DNAzyme platform for combinational catalytic therapy (NDCT) of IBD by introducing the antioxidant iridium nanozyme (IrNZ) as a protector for DNAzyme and in-situ amplifier of PAI signal.
