Kynurenines and aerobic exercise capacity in chronic kidney disease: A cross-sectional and longitudinal study.
PLoS One
January 2025
Department of Clinical Physiology, Karolinska University Hospital, Stockholm, Sweden.
Background: The causes of reduced aerobic exercise capacity (ExCap) in chronic kidney disease (CKD) are multifactorial, possibly involving the accumulation of tryptophan (TRP) metabolites such as kynurenine (KYN) and kynurenic acid (KYNA), known as kynurenines. Their relationship to ExCap has yet to be studied in CKD. We hypothesised that aerobic ExCap would be negatively associated with plasma levels of TRP, KYN and KYNA in CKD.

Tryptophan-arginine-lysine-tyrosine (WRKY) transcription factors are essential regulators of drought tolerance in multiple plants. However, whether and how GhWRKY207 modulates cotton response to drought stress is unclear. In this study, we determined that GhWRKY207 expression was high in leaves and induced by drought stress.

Accumulating evidence suggests that gut microbiota (GM) plays a crucial role in Alzheimer's disease (AD) pathogenesis and progression. This narrative review explores the complex interplay between GM, the immune system, and the central nervous system in AD. We discuss mechanisms through which GM dysbiosis can compromise intestinal barrier integrity, enabling pro-inflammatory molecules and metabolites to enter systemic circulation and the brain, potentially contributing to AD hallmarks.

Olanzapine (OLZ) is widely used in the treatment of schizophrenia, and its metabolic side effects have garnered significant attention in recent years. Despite this, the specific side effects of OLZ and the underlying mechanisms remain inadequately understood. To address this gap, zebrafish (Danio rerio) were exposed to OLZ at concentrations of 35.

BMC Plant Biol
January 2025
Faculty of Animal Science and Technology, Yunnan Agricultural University, Kunming, 650201, China.
Background: Space-induced plant mutagenesis, driven by cosmic radiation, offers a promising approach for the selective breeding of new plant varieties. By leveraging the unique environment of outer space, we successfully induced mutagenesis in 'Deqin' alfalfa and obtained a fast-growing mutant. However, the molecular mechanisms underlying its rapid growth remain poorly unexplored.
