    Abstract:
    Bovine perimuscular fat (PMF) preadipocytes were induced to undergo adipogenesis in vitro in our recent study to define the expression patterns of genes involved in the differentiation process. Based on the understanding of the interaction among adipogenic genes, a broad overview of gene expression profile in the differentiating PMF preadipocytes was evaluated using bovine specific DNA microarray from day 2 to 8 post-differentiation induction. A total of 100 significantly differentially expressed genes were detected between differentiated and control cells including those involved in several biochemical pathways and cellular/molecular signaling. In addition, quantitative real-time PCR validated that typical adipogenic genes were up-regulated at early differentiation in the preadipocytes. These results suggest that the PMF preadipocyte system is available as a novel in vitro model for molecular adipogenesis studies in the bovine and that a series of genes are switched on/off during early events associated with adipogenesis.
