However, the precise mechanism of hepatotoxicity and hepatocarcinogenesis caused by excessive cholesterol consumption remains unclear. We aimed to investigate the impact of dietary cholesterol using hepatitis C virus core gene transgenic (HCVcpTg) mice, which spontaneously developed HCC with age. Male HCVcpTg mice were treated for 15months with either a control diet or an isocaloric diet containing 1.5% cholesterol, and liver phenotypes and tumor-associated signaling pathways were evaluated. The high-cholesterol diet-fed HCVcpTg mice exhibited a significantly higher incidence of liver tumors compared with the control diet mice (100% vs. 41%, P\u003c0.001). The diet induced steatohepatitis with pericellular fibrosis and evoked higher mRNA expression of pro-inflammatory and pro-fibrotic mediators along with enhanced hepatocyte proliferation and greater oxidative and endoplasmic reticulum stress in the liver. Moreover, long-term consumption of cholesterol-rich diet activated nuclear factor-kappa B (NF-kappa B) and p62/sequestosome 1 (Sqstm1)-nuclear factor erythroid 2 (NRF2) axis, enhanced fibrogenesis, and consequently accelerated hepatic tumorigenesis. In conclusion, these results demonstrate that a high-cholesterol diet facilitates liver tumorigenesis by inducing steatohepatitis, promoting hepatocyte division, and up-regulating cellular stress and pro-inflammatory NF-kappa B and detoxifying p62/Sqstm1-NRF2 signals. Therefore, high dietary cholesterol should be avoided in HCV-infected patients to prevent development of steatohepatitis, liver fibrosis, and HCC."}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "\u738b, \u6681\u7d4c"}], "nameIdentifiers": [{"nameIdentifier": "109522", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2020-06-12"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "16MH201D_yoshi.pdf", "filesize": [{"value": "114.2 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 114200.0, "url": {"label": "\u5185\u5bb9\u306e\u8981\u65e8", "url": "https://soar-ir.repo.nii.ac.jp/record/21395/files/16MH201D_yoshi.pdf"}, "version_id": "f08d6595-3522-48ac-9be2-1fedc6f6e211"}, {"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2020-06-12"}], "displaytype": "detail", "download_preview_message": "", "file_order": 1, "filename": "16MH201D_shinsa.pdf", "filesize": [{"value": "116.4 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 116400.0, "url": {"label": "\u5be9\u67fb\u7d50\u679c\u306e\u8981\u65e8", "url": "https://soar-ir.repo.nii.ac.jp/record/21395/files/16MH201D_shinsa.pdf"}, "version_id": "2ebbb447-a6e4-4453-ae75-5aaac89fc46c"}, {"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2020-06-12"}], "displaytype": "detail", "download_preview_message": "", "file_order": 2, "filename": "16MH201D_ronbun.pdf", "filesize": [{"value": "2.4 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensefree": "This is a post-peer-review, pre-copyedit version of an article published in Archives of Toxicology.
