Abstract:
This study examined liver transcriptomic profiles of cattle distinctly different in meat and milk production capacity. It was performed on bulls of two different genetic backgrounds: Herefords (H), a meat breed, and Holstein-Friesians (HF), a dairy breed. Using bovine long oligo-microarrays and qPCR, we identified 128 genes that are differentially expressed between the two breeds. In H bulls, we observed up-regulation of genes involved in fatty acid biosynthesis and lipid metabolism (CD36, CAT, HSD3B1, FABP1, ACAA1) and involved in insulin signaling (INSR, INSIG2, NR4A1) and down-regulation of genes involved in somatotropic axis signaling (IGF1, GHR, IGFBP3) as compared to HF. Transcriptome profiling of these two breeds allowed us to pinpoint the transcriptional differences between Holstein and Hereford bulls at hepatic level associated with changes in metabolism and postnatal growth.
