Identification of differentially expressed genes between hepatocytes of Landes geese (Anser anser) and Sichuan White geese (Anser cygnoides).

In this study, we examined gene expression in order to identify genes that are differentially expressed between the hepatocytes of Sichuan White geese and Landes geese. We hypothesized that such genes may be involved in the different predispositions between these two species to develop hepatic steatosis. RNA was isolated from primary hepatocytes of the two species, and suppression subtractive hybridization was employed to screen for genes that showed differences in mRNA expression.
