  1. USC Addiction and Violence Research Center Jean C. Shih, Ph.D. School of Pharmacy University of Southern California

  2. The First Structure of MAOB(Nat. Struc. Bol. 2002)

  3. MAO A- inhibitor interaction

  4. MAO B Gene Regulation Stress Inflammatory cytokines growth factors PMA Growth factors mitogens PKC cytoplasm MAPK Pathway nucleus Egr-1 c-Jun Sp3 Sp3 / BTEB2 TIEG2 MAO B Gene TATA CACCC Sp1 / Sp4

  5. MAO B KO mice Wild type mice MAO A/B double KO mice MAO A KO mice

  6. Forebrain-specific transgenic MAO A KO mice 5-HT, NE, DA normal level in forebrain No aggression MAO B KO mice PEA  No aggression MAO A/B double KO mice 5-HT, NE, DA   PEA   Anxiety Disregulation of heart rate MAO A KO mice 5-HT, NE, DA  aggression Different levels of 5-HT lead to different signaling pathways which lead to different behaviors The increased 5-HT in forebrain is responsible for aggression
