Prostaglandin E2

Application
For use in cell culture applications for the study of prostaglandin regulated cell signaling and gene regulation.
Prostaglandin E2 has been used to determine its effects on collagen gel contraction mediated by alveolar cell carcinoma cell line A549.[1] Biochem/physiol Actions
Most biologically active prostaglandin.
Most biologically active prostaglandin. PGE2 induces cervical ripening and parturition; mediates bradykinin-induced vasodilation; regulates adenylyl cyclase. Tumor cells that over-express cyclooxygenase 2 display increased invasiveness, angiogenesis, and resistance to apoptosis that may be due to the PGE2-induced expression of angiogenic factors and stabilization of the anti-apoptotic protein, survivin.The effect of PGE2 on the immune system is mixed. It inhibits T cell activation in vitro, suggesting it is an immunosuppressant. However, in vivo, it appears to effect expansion of the Th17 subset and differentiation of the Th1 subset of T helper cells, marking it as an immunoactivator.
