Template:PBB Pleiotrophin (heparin binding growth factor 8, neurite growth-promoting factor 1), also known as PTN, is a human gene.[1]
Pleiotrophin or Neurite Growth-promoting Factor 1 (NEGF1), also called Heparin Affin Regulatory Peptide (HARP) or Heparin Binding Growth associated molecule (HB-GAM) is an 18-kDa growth factor that has a high affinity for heparin. It is structurally related to midkine and retinoic acid induced heparin-binding protein.
Pleiotrophin was initially recognized as a neurite outgrowth-promoting factor present in rat brain around birth[2]and as a mitogen toward fibroblasts isolated from bovine uterus tissue.[3] Together with midkine these growth-factors constitute a family of (developmentally regulated) secreted heparin-binding proteins[4] now known as the Neurite Growth-promoting Factor (NEGF) family. During embryonic and early postnatal development, pleiotrophin is expressed in the central and peripheral nervous system and also in several non-neural tissues, notably lung, kidney, gut and bone.[5] Pleiotrophin is also expressed by several tumor cells and is thought to be involved in tumor angiogenesis.[6] In the adult central nervous system Pleiotrophin is expressed in an activity-dependent manner in the hippocampus[7][8] where it can suppress long term potentiation induction.[9] Pleiotrophin expression is low in other areas of the adult brain, but it can be induced by ischemic insults.[10][11]
