Impaired Kynurenine Pathway in Inflammatory Bowel Disease

Journal of Clinical Medicine
Background/Objectives: Inflammatory bowel diseases primarily encompass Crohn’s disease and ulcerative colitis. Insufficient levels of tryptophan cause an imbalance in the gut microbiota, leading to inflammation in the gastrointestinal tract. The main catabolic pathway of tryptophan is the kynurenine pathway. Our study aims to evaluate serum tryptophan,

The Silent Link: Exploring the Impact of Periodontal Diseases on Head and Neck Carcinogenesis

Clinical and Experimental Dental Research, Volume 12, Issue 3, June 2026.
ABSTRACT Objectives Oral dysbiosis can accelerate the progression of head and neck squamous cell carcinoma (HNSCC) by fostering a pro‐inflammatory, immunosuppressive, and metabolically altered environment. This narrative review examines the relationships between periodontitis‐associated bacteria and HNSCC, focusing on their impact on oncogenic pathways,

Cancer IDO1‐Mediated Tryptophan–Kynurenine Metabolic Reprogramming to Drive Skeletal Muscle Atrophy and Cachexia Acceleration

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 3, June 2026.
ABSTRACT Background Cancer cachexia is a debilitating syndrome characterized by severe skeletal muscle wasting, which significantly impairs patient quality of life and survival. Indoleamine 2,3‐dioxygenase 1 (IDO1), a key enzyme in tryptophan (Trp) metabolism, is often upregulated in cancers, but its specific role in driving lung cancer–associated ...

Oxidative Stress in the Tumor Immune Microenvironment: Mechanisms and Therapeutic Perspectives

MedComm – Oncology, Volume 5, Issue 2, June 2026.
Oxidative stress is involved in several key processes in cancer, including redox regulation, DNA damage, post‐translational modifications, transcriptional regulation, epigenetic modifications, metabolic reprogramming, cell death, and immune modulation. These mechanisms collectively influence tumor progression, immune evasion, and therapeutic responses,

Glucuronolactone Promotes Mucin Sulfation to Alleviate Deoxynivalenol‐Induced Intestinal Injury via Microbiota‐Dependent and ‐Independent AHR Activation

Advanced Science, Volume 13, Issue 25, 4 May 2026.
Glucuronolactone (GLU) as a natural metabolite of glucose, increases Lactobacillus amylovorus abundance and luminal IAA level to activate AHR signaling. In addition, GLU itself can directly elevate AHR signaling activity independently of microbiota and IAA.

NAD+‒circadian rhythm coupling in dementia

Alzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract The circadian rhythm system and sleep coordinate whole‐body functions across the 24‐h cycle, yet these rhythms progressively deteriorate with neurodegenerative diseases, including dementia. Growing evidence indicates that nicotinamide adenine dinucleotide (NAD+) interacts with the circadian system through multiple molecular pathways and that ...

Natural Products as the Modulators of Gut Microbiota: A Pool for the Development of New Treatment Against Obesity?

Food Frontiers, Volume 7, Issue 3, May 2026.
Natural compounds regulate gut microbiota by improving microbial balance and increasing probiotics, which boost short‐chain fatty acid production to alleviate insulin resistance and inflammation. Additionally, they stimulate appetite‐suppressing hormones through bile acid signaling, while inhibiting pathogenic bacteria to repair intestinal barrier ...
