Oxidative stress is suggested to play an important role in several pathophysiological conditions. A recent study showed that decreasing 5-oxoproline (pyroglutamate) concentration, an important mediator of oxidative stress, by over-expressing 5-oxoprolinase, improves cardiac function post-myocardial infarction in mice. The aim

Inhibition of prostaglandin E2 signaling via EP2/EP4 prostanoid receptors suppresses Insulin-like growth factor (IGF)-1-induced proliferation of pancreatic cancer BxPC-3 cells. To better understand the mechanism of EP2/EP4 signaling for controlling cell proliferation, we performed metabolome analyses in BxPC-3 cells treated with IGF-1
