Liver tissue from the "Four Core Genotype" treated group C57BL/6J mice versus pool C57BL/6J mice of chow diet Liver

The purpose of this experiment was to determine the expression traits in Liver tissue from the Four Core Genotype treated group. Keywords: Sry transgene Four Core Genotype Mouse liver Tissue Liver tissue from the "Four Core Genotype" treated group consists of 20 female and male C57BL/6J mice fed a chow diet containing 4% fat (Ralston-Purina Co., St. Louis, MO) until 8 weeks of age and then were gonadectomized at 8 weeks of life. In mice of the "four core genotypes" (FCG), the Y chromosome is deleted for the testis-determining gene Sry, producing the Y- chromosome. The Sry transgene is inserted onto an autosome, so that testis determination is independent of the complement of sex chromosomes. XY-Sry gonadal males are bred with XX gonadal females, producing progeny with four different genotypes: two types of gonadal males (XX.Sry and XY-Sry) and two types of gonadal females (XX and XY-). At 12 weeks mice were sacrificed, after a 12-hour fast, Liver tissue were dissected and flash frozen in LN2 and stored at -80°C. All sample were compared to a common pool created from equal portions of RNA from each of the samples.
