Examining the Role of Histaminergic, Orexinergic, and Cannabinergic Systems in Redox Regulation in Gastric Adenocarcinoma.

Histaminergic, orexinergic, and cannabinoid systems play a role in both physiologic and oncogenic mechanisms in digestive tissues. These three systems are important mediators of tumor transformation, as they are associated with redox alterations, which are key aspects in oncological disorders. The three systems are known to promote alterations in the gastric epithelium through intracellular signaling pathways, such as oxidative phosphorylation, mitochondrial dysfunction, and increased Akt, which might promote tumorigenesis.
