Essential tremor (ET) stands as one of the most prevalent cerebellar movement disorders. However, effective treatment remains elusive, largely due to a limited understanding of its molecular pathology. Harmaline-induced tremor in mouse is a well-established animal model for ET, while with enigmatic mechanism. The aim of this study was to get insight into the molecular intricacies underlying cerebellar dysfunction in harmaline-induced tremor. Combining LC-MS/MS and RNA-Seq analysis, we delved into the variation of the cerebellum between harmaline-induced tremor and the control ones. This comprehensive investigation revealed a profile of this mouse model from mRNA and protein level, highlighting 5194 correlated coding molecules, with 19 proving to be significant. Further KEGG enrichment analysis identified cerebellar serotonin transporter (SERT) as the key molecule in harmaline-induced tremor. The implications of this transcriptomic and proteomic exploration underscore the potential therapeutic value of targeting SERT as a novel treatment approach for ET. In general, our study unveils crucial insights that could pave the way for molecular target identification and effective therapeutic interventions for ET.
