Int J Mol Sci 2019; 20:E6084. [PMID: 31816816 PMCID: PMC6928943 DOI: 10.3390/ijms20236084] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2019] [Revised: 11/13/2019] [Accepted: 11/22/2019] [Indexed: 01/18/2023] Open
Abstract
Effective, targeted therapy for chronic liver disease nonalcoholic steatohepatitis (NASH) is imminent. MicroRNAs (miRNAs) are a potential therapeutic target, and natural products that regulate miRNA expression may be a safe and effective treatment strategy for liver disease. Here, we investigated the functional role of miR-451 and the therapeutic effects of genistein in the NASH mouse model. MiR-451 was downregulated in various types of liver inflammation, and subsequent experiments showed that miR-451 regulates liver inflammation via IL1β. Genistein is a phytoestrogen with anti-inflammatory and anti-oxidant effects. Interestingly, we found that the anti-inflammatory effects of genistein were related to miR-451 and was partially antagonized by the miR-451 inhibitor. MiR-451 overexpression or genistein treatment inhibited IL1β expression and inflammation. Taken together, this study shows that miR-451 has a protective effect on hepatic inflammation, and genistein can be used as a natural promoter of miR-451 to ameliorate NASH.

Fang Z, Zhou L, Jiang S, Cao L, Yu L. UNC50 prompts G1/S transition and proliferation in HCC by regulation of epidermal growth factor receptor trafficking. PLoS One 2015; 10:e0119338. [PMID: 25738771 PMCID: PMC4349650 DOI: 10.1371/journal.pone.0119338] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2014] [Accepted: 01/27/2015] [Indexed: 01/04/2023] Open
Abstract
Background UNC50 has long been recognized as a Golgi apparatus protein in yeast, and is involved in nicotinic receptor trafficking in Caenorhabditis elegans, but little is known about UNC50 gene function in human biology despite it being conserved from yeast to high eukaryotes. Objectives We investigated the relation between UNC50 and human hepatocellular carcinoma (HCC) and the potential mechanisms underlying HCC development. Methods UNC50 mRNA expression patterns in 12 HCC and adjacent non-cancerous tissues determined using northern blotting were confirmed by real-time PCR in another 44 paired tissues. Microarray experiments were used to screen for global effects of UNC50 knockdown in the Hep3B cell line, and were confirmed by real-time PCR, western blotting, flow cytometry, and tetrazolium assay in both UNC50 overexpression and knockdown Hep3B cells. Results UNC50 expression levels were upregulated in HCC tissues in comparison with the adjacent non-cancerous tissues. UNC50 knockdown reduced mRNA levels of the downstream targets of the epidermal growth factor receptor (EGFR) pathway: cyclin D1 (CCND1), EGF, matrix metalloproteinase-7 (MMP7), aldose reductase-like 1 (AKR1B10), cell surface–associated mucin 1 (MUC1), and gastrin (GAST). Moreover, UNC50 influenced EGF, inducing cell cycle entry by affecting cell surface EGFR amounts. Conclusions UNC50 may plays some roles in HCC progression by affecting the EGFR pathway.
