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

DEGs in the liver of cold-exposed Altay and Hu lambs. 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 (n = 5) compared to −5°C Hu lambs (n = 6); A-liver^w-H-liver^w: liver of 20°C Altay lambs (n = 4) compared to 20°C Hu lambs (n = 4). (a) DEGs among different treatment groups. (b) DEGs between differently compared groups. (c) The up- and downregulated DEGs between differently compared groups. The screen of DEGs is based on |log2 FC| > 1 and q value < 0.05. The green columns represent upregulated DEGs, and blue columns represent downregulated DEGs.
