Fucoidan exerts antitumor effects by regulating gut microbiota and tryptophan metabolism.
Int J Biol Macromol
January 2025
State Key Laboratory of Marine Food Processing & Safety Control, College of Food Science and Engineering, Ocean University of China, China.
Fucoidan, a water-soluble polysaccharide derived from marine organisms, has garnered significant attention for its ability to regulate gut microbiota and its anti-tumor properties. However, the existence of a correlation between the anti-tumor effect of fucoidan and its regulation of the gut microbiota remains unknown. In pursuit of this objective, we culled the gut microbiota of mice with broad-spectrum antibiotics to generate pseudo-sterile tumor-bearing mice.

: Several studies suggest gut microbiota metabolites as important immuno-modulators in inflammatory pain. We aimed to investigate the relationship between vitamin D status and gut dysbiosis markers in fibromyalgia (FM)-associated chronic inflammation. : Blood samples were collected from sixty-eight female FM patients (49.

Aim of the current study is to evaluate in patients with neuroendocrine tumor (NET): 1) T and K concentrations; 2) correlation with clinical outcome; 3) relationship between IDO activity and inflammatory cytokines.
Methods: A cross-sectional study was performed to investigate the IDO pathway in patients in follow-up for NET.
Peripheral tryptophan-kynurenine pathway dysfunction in first-episode schizophrenia.
Sci Rep
January 2025
Affiliated Mental Health Centre & Hangzhou Seventh People's Hospital, Zhejiang University School of Medicine, Hangzhou, 310013, China.
The tryptophan (TRP)-kynurenine (KYN) pathway is involved in the pathogenesis of schizophrenia. This study aimed to investigate the levels of TRP-KYN metabolites in serum and urine of patients with first-episode schizophrenia (FES) and their association with clinical manifestations. This study included 38 drug-naive patients with FES and 43 healthy controls (HCs).
