TXA2 is a bioactive lipid mediator primarily produced via the action of cyclooxygenases (COX-1/COX-2) and thromboxane synthase (TXA2S, gene TBXAS1), and it plays a role in regulating platelet aggregation, vasoconstriction, and cellular signaling that may contribute to tumor progression.
TXA2 is a bioactive lipid mediator that, beyond its role in platelet aggregation and vascular regulation, is involved in several tumor-promoting processes such as inflammation, angiogenesis, and metastasis. In various cancers—such as breast, prostate, colorectal, lung, ovarian, and head and neck cancers—elevated TXA2 levels or enhanced signaling have been associated with more aggressive disease and poorer clinical outcomes.
