Transcriptome Profiles of the Liver in Two Cold-Exposed Sheep Breeds Revealed Different Mechanisms and Candidate Genes for Thermogenesis

Figure 2

The significant upregulated GO terms and KEGG pathways of DEGs in the liver. A-liver^c-A-liver^w: liver of −5°C Altay lambs (n = 5) compared to 20°C Altay lambs (n = 4); H-liver^c-H-liver^w: liver of −5°C Hu lambs (n = 6) compared to 20°C Hu lambs (n = 4); A-liver^c-H-liver^c: liver of −5°C Altay lambs compared to −5°C Hu lambs; A-liver^w-H-liver^w: liver of 20°C Altay lambs compared to 20°C Hu lambs. The screen of significant enrichment is based on q value < 0.05. The green columns represent the group of A-liver^w-A-liver^c, the red columns represent the group of H-liver^w-H-liver^c, the khaki columns represent the group of H-liver^c-A-liver^c, and the gray columns represent the group of H-liver^w-A-liver^w.
