In all cases of venous PT, selective embolization of the MEV caused the tinnitus to disappear, suggesting technical success. In contrast, embolization of the MEV had no effect in patients with neutral PT. CONCLUSIONS We demonstrated that MEV could be a source of venous PT. Embolization of the MEV was effective only in cases of clinical venous PT. © Author(s) (or their employer(s)) 2020. No commercial re-use. See rights and permissions. Published by BMJ.Excessive lipid deposition is a hallmark of nonalcoholic fatty liver disease (NAFLD). Although much has been learned about the enzymes and metabolites involved in NAFLD, few studies have focused on the role of long non-coding RNAs (lncRNAs) in hepatic lipid accumulation. Here, using in vitro and in vivo models of NAFLD, we found that the lncRNA Gm15622 is highly expressed in the liver of obese mice fed a high-fat diet (HFD) and in murine liver (AML-12) cells treated with free fatty acids. Investigating the molecular mechanism in the liver-enriched expression of Gm15622 and its effects on lipid accumulation in hepatocytes and on NAFLD pathogenesis, we found that Gm15622 acts as a sponge for the microRNA miR-742-3p. This sponging activity increased the expression of the transcriptional regulator sterol regulatory element-binding transcription factor 1c (SREBP-1c) and promoted lipid accumulation in the liver of the HFD mice and AML-12 cells. Moreover, further results indicated that metformin suppresses Gm15622 and alleviates NAFLD-associated lipid deposition in mice. In conclusion, we have identified an lncRNA Gm15622-miR-742-3p-SREBP-1c regulatory circuit associated with NAFLD in mice, a finding that significantly advances our insight into how lipid metabolism and accumulation are altered in this metabolic disorder. Our results also suggest that Gm15622 may be a po
