Zhu et al. (2019) and others used RNA‐seq technology to sequence the liver transcriptome of rats with diet‐induced obesity treated with patchouli and found that the lipid‐lowering effect of patchouli on rats with diet‐induced obesity may be mediated by regulating the expression of Fasn‐, Socs2‐, and Ppp1r3b‐related genes and proteins in the insulin signaling pathway. Here, FASN is linked to obesity disorder.
