Notes: Lysophosphatidylethanolamine (LPE) is a naturally-occurring lysophospholipid that can be generated via deacylation of phosphatidylethanolamine by phospholipase A2 (PLA2).{46055,46056} It increases the phosphorylation of ERK1/2 in PC12 cells, an effect that can be blocked by the MEK inhibitors U-0126 (Item No. 70970) and PD 98059 (Item No. 10006726) and the EGFR inhibitor AG-1478 (Item No. 10010244).{46055} LPE also increases neurite outgrowth and expression of neurofilament M in PC12 cells. LPE inhibits the activity of phospholipase D (PLD) partially purified from cabbage.{46057} This product contains lysophosphatidylethanolamine molecular species with variable fatty acyl chain lengths at the sn-1 position and a hydroxy group at the sn-2 position.
