Phloridzin reveals new treatment strategies for liver fibrosis

ABSTRACT: Liver fibrosis, is an urgent public health problem and is difficult to resolve. However, various drugs for the treatment of liver fibrosis in clinical practice have their own problems during use. In this study, we used phloridzin to treat hepatic fibrosis in the CCl4-induced C57/BL6N mouse model, which was extracted from lychee core, a traditional Chinese medicine. The therapeutic effect was evaluated by biochemical index detections and ultrasound detection. Furthermore, in order to determine the mechanism of phloridzin in the treatment of liver fibrosis, we performed high-throughput sequencing of messenger RNA (mRNA) and long non-coding RNA (lncRNA) in different groups of liver tissues, and screened for differentially expressed genes, as well as performed gene co-expression analysis of the differential lncRNAs and mRNAs. The results showed that compared with the model group, the phloridzin treated groups showed a significant decrease in collagen deposition, and decreased levels of serum alanine aminotransferase, aspartate aminotransferase, laminin and hyaluronic acid. GO and KEGG pathway enrichment analysis of the differential mRNAs was performed and revealed that phloridzin mainly affects cell ferroptosis. Gene co-expression analysis showed that the target genes of lncRNA were obvious in cell components such as focal adhesions, intercellular adhesion, and cell-substrate junctions, and in metabolic pathways such as carbon metabolism. These results showed that phloridizin can effectively treat liver fibrosis, and the mechanism may involve ferroptosis, carbon metabolism and related changes in biomechanics.

Transcriptome Analysis Reveals Potential Protective Effects and Biomarkers of Pien Tze Huang on CCl4-induced Liver Cancer (miRNA)

Project description:Pien Tze Huang (PZH) is a traditional Chinese medicinal formula that has been extensively used in Asia for the treatment of liver diseases. We created two groups of liver cancer mouse models induced by carbon tetrachloride (CCl4): one group received treatment with PZH and the other did not receive any treatment. In the non-PZH treated group, we observed a significant increase in liver function indices including albumin (ALB), alanine aminotransferase (ALT), and aspartate aminotransferase (AST). Histological examination using hematoxylin and eosin (HE) staining revealed inflammation around the hepatic vein in the non-PZH treated group. Furthermore, Masson's trichrome staining demonstrated the presence of blue-stained collagen fibers around the hepatic vein in the non-PZH treated group. These findings suggest that PZH may have therapeutic effects on liver inflammation and cancer. To further explore the molecular mechanisms of PZH's action, we conducted mRNA, long non-coding RNA (lncRNA), circular RNA (circRNA), and microRNA (miRNA) sequencing to identify potential drug targets at the transcriptome level. We identified 478 differentially expressed protein-coding transcripts and 68 differentially expressed lncRNA transcripts. Our study provides insights into potential transcriptional therapeutic targets for the clinical use of PZH in treating liver diseases.

Expression data from murine fibrotic liver tissues and normal liver tissues

Project description:Long noncoding RNAs (lncRNAs) play important roles in various biological processes; however, few have been identified that regulate hepatic stellate cells (HSCs) activation and the progression of liver fibrosis. To identify the possible roles of lncRNAs in regulating liver fiboris and the potential of lncRNAs as molecular markers for liver fiboris, we systematically analyzed the regulation of lncRNAs and mRNAs in a mouse model of carbon tetrachloride (CCl4)-induced liver fibrogenesis by microarray analysis, which revealed a panel of lncRNAs and mRNAs that were specifically regulated in livers of mice undergoing hepatic fibrosis. To identify the possible roles of lncRNAs in regulating liver fiboris and the potential of lncRNAs as molecular markers for liver fiboris,we determined the lncRNA and mRNA expression profiles in the livers of fibrotic mice and normal mice by lncRNA and mRNA microarrays.

Gene expression analysis of micoRNA-221 overexpressing transgenic mice livers with and without metformin intervention upon chronic liver injury induced by carbon tetrachloride

Project description:Metformin is a hypoglycaemic agent used to treat type 2 diabetes mellitus (DM2) patients, with a broad safety profile. Since previous epidemiological studies had shown that incidence of hepatocellular carcinoma (HCC) decreased significantly in metformin treated DM2 patients, we hypothesized that intervention with metformin could reduce the risk of neoplastic transformation of hepatocytes. HCC is the most common primary liver malignancy and it generally originates in a background of liver fibrosis and cirrhosis. In the present study, we took advantage of a transgenic mouse (TG221) characterized by microRNA-221 overexpression, with cirrhotic liver background induced by chronic administration of carbon tetrachloride (CCl4). This mouse model develops fibrosis, cirrhosis and liver tumors that become visible in 100% of mice at 5-6 months of age.

Sophoridine derivative 6j inhibits liver cancer cell proliferation via ATF3 mediated ferroptosis

Project description:Liver cancer is one of the most lethal malignancies with an annual death of over 830,000 cases. Although targeted therapeutic drugs have achieved certain clinical efficacy, only sorafenib and lenvatinib are currently marketed as first-line targeted drugs to treat patients with advanced liver cancer. Therefore, developing more drugs are urgently needed. Ferroptosis is an iron-dependent programmed cell death (PCD) distinct from known PCDs including apoptosis, necrosis, and autophagy. Targeting ferroptosis is recognized as a promising potential therapeutic modality for liver cancer. Activating transcription factor 3 (ATF3) is an important ferroptosis inducer and targeting ATF3 offers a potential means to cancer therapy. In the present study, we reported for the first time a sophoridine derivative 6j with promising anti-liver cancer effects in vitro and in vivo. Compound 6j could induce liver cancer cells ferroptosis by promoting the accumulation of intracellular Fe2+, reactive oxygen species (ROS), and MDA. Inhibition of ferroptosis by ferrostatin-1 alleviated 6j induced accumulation of Fe2+, ROS, and MDA and restored cell viability. Further study revealed that compound 6j upregulated the expression of ATF3 via ER stress and knockdown of ATF3 by RNA interference attenuated 6j induced ferroptosis and cell proliferation inhibition. This study would provide new insights for the design of ferroptosis inducers and the development of anti-liver cancer drugs.

Expression data that were specifically regulated by lncRNA-LFAR1 in mouse primary HSCs

Project description:Long noncoding RNAs (lncRNAs) play important roles in various biological processes; however, few have been identified that regulate hepatic stellate cells (HSCs) activation and the progression of liver fibrosis. Through a detailed analysis of the expression of lncRNAs in various tissues, we discovered the existence of a liver enriched lncRNA-LFAR1 (lncRNA-Liver Fibrosis Associated RNA1). To identify the roles of lncRNA-LFAR1 in liver fiboris, we systematically analyzed the regulation of mRNAs in primary HSCs infected with two separated lnc-LFAR1-shRNAs by RNA-seq, which revealed a panel of mRNAs that were specifically regulated by lncRNA-LFAR1 in mouse primary HSCs.

S100a16 deficiency prevents liver fibrosis via inhibiting C-X-C motif chemokine receptor 4 expression

Project description:Liver fibrosis has been implicated in the pathogenesis of various liver disease. Thus far, there is still no effective intervention means for this process. Recently, we have demonstrated that S100A16 participated in liver lipid accumulation and renal fibrosis. Therefore, we hypothesized that S100A16 took a critical role in liver fibrosis. S100a16 transgenic and knockdown mice were generated and stimulated with carbon tetrachloride, bile duct ligation and methionine choline deficiency diet. Alterations of gene expression in hepatic stellate cells from wild type and S100a16+/- mice were investigated by transcriptome sequencing. S100A16 expression levels in liver tissue of patients and rodent models of liver fibrosis were markedly increased. S100a16 transgenic mice showed spontaneous liver fibrosis after normal feeding for 6 months. On the contrary, silencing of S100a16 exhibited obvious protective effect against liver fibrosis caused by different stimulations. Meanwhile, results showed that deletion of S100a16 significantly inhibited hepatic stellate cells (HSCs) activation cultured in fetal bovine serum contained medium. RNA sequencing results revealed that mechanistically, C-X-C motif chemokine receptor 4 (Cxcr4) participated in the process of S100a16 in liver fibrosis. Knockdown of S100a16 inhibited Cxcr4 expression through augmenting P53 expression. SDF-1α/CXCR4-dependent extracellular signal-regulated kinase 1/2 and Akt phosphorylation mediated the effects of S100a16 on α-smooth muscle actin expression and HSCs activation. These data indicate that S100a16 deficiency prevents liver fibrosis by inhibiting Cxcr4 expression. Targeting S100A16 may provide insights into the pathogenesis of liver fibrosis and pave the way for developing strategies for liver fibrosis-related diseases prevention and treatment.

Conserved long noncoding RNA TILAM promotes liver fibrosis in humans and mice.

Project description:Fibrosis is the common endpoint for all forms of chronic liver injury, and progression of fibrosis is responsible for the development of end stage liver disease and liver failure. The activation of hepatic stellate cells (HSCs) and their transition to HSC myofibroblasts is a key step in the disease process, as these cells are the primary source of the extracellular matrix (ECM) proteins, which form the fibrotic scar. Long noncoding (lnc) RNAs can regulate the activity of HSCs, and lncRNAs that promote the fibrotic activity of HSCs may provide targets for antifibrotic therapies. Here, we identified and defined the functional mechanisms of a conserved lncRNA that plays a critical role in promoting liver fibrosis. We found that TILAM is conserved between human and mouse HSCs, and regulates expression of type 1 collagen, a major component of the ECM. To determine the role of TILAM in vivo, we annotated the mouse ortholog (Tilam), generated Tilam-deficient GFP-reporter mice, and challenged these mice in two different models of liver fibrosis. Analysis of GFP expression revealed that Tilam is induced in murine HSCs with the development of fibrosis in vivo. In both male and female mice, we also observed that loss of Tilam resulted in reduced fibrosis in the setting of injury induced by carbon tetrachloride (CCl4) and choline-deficient L-amino acid defined high fat diet (CDA-HFD). Finally, we found that TILAM interacts with PML to stabilize PML protein expression and promote the fibrotic activity of HSCs. Together, these results define an lncRNA conserved between humans and mice that is activated uniquely in HSCs to drive the development of fibrosis and could provide a therapeutic target to combat the development of end stage liver disease.
