Ours could be the 1st proof suggesting that PGE KPT-8602 site pretreatment can phosphorylate GSK. Unexpectedly, the PGE(H) pretreated group had decreased phosphorylation of Akt at Ser. We identified two mechanisms potentially explaining this observation:) GSK signaling is mediated not only by Akt, but in addition by ERK, pMAPK, JNK, Wnt and so forth , which could also have cardioprotective efficacy, with crosstalk among them.
