Glycolytic reprogramming impairs chondrocyte function in broilers with femoral head necrosis.

ABSTRACT: Cartilage extracellular matrix (ECM) destruction is a hallmark of femoral head necrosis (FHN) in broilers. Chondrocytes undergo metabolic reprogramming under stress to maintain function. However, the metabolic alterations in FHN chondrocytes remain unclear. This study aims to investigate the overall changes of metabolic state in FHN chondrocytes and its functions. Femoral head cartilage of healthy and FHN broilers was collected for non-targeted metabolome and transcriptome analyses. Additionally, primary chondrocytes were isolated from femoral head cartilage of control (CON) and FHN broilers for bioenergetic analysis and mechanistic investigation. Multi-omics profiling revealed significant enrichment of the glycolysis pathway, decreased levels of tricarboxylic acid cycle metabolites (citra
