Circulating arginine–nitric oxide pathway metabolites and nitrated fatty acids in relation to pathological features of colorectal cancer

Colorectal cancer (CRC) is associated with metabolic and inflammatory disturbances, including alterations in the arginine–nitric oxide (NO) pathway. This study assessed serum metabolites related to the arginine–NO–nitrated fatty acid (NO₂-FA) axis in patients with CRC and examined their associations with tumor stag...

Serum metabolomics modelling reveals stage-associated purine and endocannabinoid metabolic signatures in colorectal cancer progression

Background Colorectal cancer (CRC) remains one of the major challenges in contemporary oncology. Despite advances in imaging diagnostics and histopathological assessment, we still lack tools for the early detection of micrometastases and molecular alterations. The purinergic and endocannabinoid systems play an importan...
