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.

Oleamide Induces Cell Death in Glioblastoma RG2 Cells by a Cannabinoid Receptor-Independent Mechanism.

The endocannabinoid system has been associated with antiproliferative effects in several types of tumors through cannabinoid receptor-mediated cell death mechanisms. Oleamide (ODA) is a CB1/CB2 agonist associated with cell growth and migration by adhesion and/or ionic signals associated with Gap junctions. Antiproliferative mechanisms related to ODA remain unknown.
