4 FAS Intrauterine growth retardation (IUGR) Craniofacial malformations Physical and mental retardation Background 1973 Jones and Smith Cardiac septal defects

5 Background FASD -- Foetal Alcohol Spectrum Disorders

6 Alcohol ASTROS Mechanisms of Oxidative Stress Related FASD and Prevention of AST

7 Animals and experimental treatment Wild type female mice gestational day G0: gestational day G7: AST G8:ethanol and AST G9:for RT-PCR, Western- blot, ELISA; G10:for Morphology study G9 PCR,ELISA G10:Morphology ethanol G 0 G8 Ethanol groupscontrol groups G7 AST Morphology assessment of embryos ASTBlank ASTBlank 6

8 AST prevented ethanol-induced developmental retardation in mouse embryos 7

9 Down-regulation of neural marker genes 8

10 Mechanisms of oxidative stress related FASD and prevention of AST A.malondialdehyde( MDA) B. hydrogen peroxide(H2O2) C.glutathione peroxidase per oxidase(GPx) 9

11 Intervention of AST on the TLRs system 10

12 Intervention of AST on the TLRs system A.AST inhibited ethanol- induced production of TNF-a B.AST inhibited ethanol- induced production of and IL-1bin embryos 10

13 Discussion AST pretreatment protected embryos from maternal ethanol-induced neurodevelopmental retardation and down-regulation of neural marker genes. Inflammation played a role in mechanisms of FASD. TLR4 is distinct expression in embryos and related to inflammation

14 Conclusions Our results demonstrated a protective effect of astaxanthin on fetal alcohol spectrum disorder Oxidative stress and toll-like receptor signaling associated inflammatory reaction were involved in this process.
