In the mammalian brain, serotonin receptor type 6 (Htr6) and other specific G protein-coupled receptors (GPCRs) localize preferentially to primary cilia and function in ciliary chemical detection; however, the molecular mechanism by which a subset of GPCRs is transported to primary cilia has not been fully elucidated. In the present study, we demonstrate that a region in the fourth intracellular domain of Htr6 (Htr6 i4) is sufficient for ciliary localization. In yeast, the interaction of this region with the C-terminal region of γ1-Adaptin, a subunit of adaptor protein complex 1 (AP-1), was identified. The interaction between Htr6 and γ1-Adaptin was confirmed by immunoprecipitation analysis using HEK293T cells. The preference for ciliary localization of Htr6 and Htr6 i4 was significantly decreased by ablation of <em>γ1-Adaptin</em> in hTERT RPE-1 cells, which was rescued by exogenous expression of γ1-Adaptin. Furthermore, Htr6 and Htr6 i4 showed reduced localization to primary cilia in <em>γ1-Adaptin</em>-depleted cultured hippocampal neurons compared with control neurons. These results indicate that the ciliary localization of Htr6 is facilitated by AP-1-mediated membrane trafficking.</div></div>","PeriodicalId":9902,"journal":{"name":"Cellular signalling","volume":"135 ","pages":"Article 112008"},"PeriodicalIF":4.4,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144673973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The histone methyltransferase G9a participates in the regulation of different types of cell death including ferroptosis, but its role in VC needs to be further explored. Here, we found that G9a expression was elevated in microarray data obtained from CKD mouse VSMC specimens, and further experiments demonstrated similar results in CKD patients, mouse calcified arteries and rat calcified VSMCs. Functionally, G9a overexpression promoted high calcium and phosphate-induced VSMCs calcification, whereas G9a deficiency had a protective effect. Moreover, our results confirmed that G9a promoted VSMCs calcification through cystine pathway-mediated ferroptosis. Mechanistically, histone H3 lysine 9 dimethylation (H3K9me2) which was catalyzed by G9a, interacted with the promoter of solute carrier family 7 member 11 (SLC7A11) to inhibit its transcription and ferroptosis-related signaling pathways. SLC7A11, a cysteine transporter and ferroptosis suppressor, eliminated the adverse effects of G9a overexpression on ferroptosis and VC in VSMCs. Finally, in vivo overexpression of G9a aggravated VC and ferroptosis in the aorta of CKD mice, accompanied by down-regulation of SLC7A11 expression.
