In contrast, DEGs enriched in HFD‐fed mice, including Fabp4, Apoa1, Cyp4a14, Acaa1b, Rxra, Cpt2, Hacd1, Cyp4a32, Acnat1, Acot1, Acnat2, Pltp, and Jak3 were significantly and positively associated with obesity‐abundant bacteria, such as Mucispirillum schaedleri, Lachnospiraceae bacterium 28‐4, Anaerotruncus sp. This evidence concerns the gene RXRA and Obesity.
