Biochem/physiol Actions

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.

Pressure ulcers are characterized by chronicity, which results in delayed wound healing due to pressure. Early intervention for preventing delayed healing due to pressure requires a prediction method. However, no study has reported the prediction of delayed healing due to...

Previous studies indicate that plasma levels of serotonin (5-HT) and intramuscular prostaglandin E2 (PGE2) participate in determining the mechanical pain threshold and tolerance level to pressure applied on the skin over healthy muscles. Other studies reported gender differences regarding responses...
