title: Differential gene expression in Poecilia vivipara exposed to diesel oil water accommodated fraction.
abstract: Diesel fuel is a potential contaminant of estuarine and mangrove areas, particularly because it is the main fuel used in small boats and larger vessels. The aim of this work was to identify genes differentially expressed in the liver of Poecilia vivipara (Guppy) exposed to 10% diesel fuel water accommodated fraction (WAF), employing the subtractive suppressive hybridization (SSH) method. The results showed 27 differentially expressed gene fragments, 12 up-regulated and 15 down-regulated. Among the up-regulated genes were CYP1A, UDPGT1a, ABCC4, Methyltransferase and Apolipoprotein A1. Down-regulated genes included Vitellogenins, C1 Inhibitor and Complement Component 3c. The identified genes are associated with different metabolic functions like biotransformation, membrane transport and immune system, indicating the susceptibility and/or molecular responses of this organism to the toxic effects elicited by diesel fuel WSF.
