    Abstract: Background: Zuo-Jin-Wan (ZJW), a two-herb formula consisting of Coptis chinensis (CC) and Evodia rutaecarpa (ER), is commonly used in traditional Chinese medicine for the treatment of cancers. However, the efficacies and mechanisms of ZJW and its ... ...

    Abstract Background: Zuo-Jin-Wan (ZJW), a two-herb formula consisting of Coptis chinensis (CC) and Evodia rutaecarpa (ER), is commonly used in traditional Chinese medicine for the treatment of cancers. However, the efficacies and mechanisms of ZJW and its alkaloid components on cancers are still unclear.
    Methods: Here we investigated the anti-cancer effects and mechanisms of ZJW, CC, ER, berberine, and evodiamine in cells and in intrahepatic xenograft mice.
    Results: Treatment of HepG2 cells with ZJW, CC, ER, berberine, and evodiamine significantly displayed cytotoxic effects in a dose- and time-dependent manner. Hierarchical cluster analysis of gene expression profiles showed that CC and ZJW shared a similar mechanism for the cytotoxic effects, suggesting that CC was the active ingredient of ZJW for anti-cancer activity. Network analysis further showed that c-myc was the likely key molecule involved in the regulation of ZJW-affected gene expression. A human hepatoma xenograft model was established by intrahepatic injection of HepG2 cells containing nuclear factor-κB-driven luciferase genes in immunocompetent mice. In vivo bioluminescence imaging showed that cells had been successfully transplanted in mouse liver. Oral administration of ZJW for 28 consecutive days led to a significant decrease in the accumulation of ascites, the ratio of tumor-to-liver, and the number of transplanted cells in livers.
    Conclusions: In conclusion, our findings suggested for the first time that ZJW significantly suppressed human cancer cell growth in orthotopic HepG2 xenograft-bearing immunocompetent mice. Moreover, c-myc might play a potent role in the cytotoxic mechanisms of ZJW, CC, ER, berberine, and evodiamine.

    Abstract Ethnopharmacological relevance: Hibiscus sabdariffa Linn., also known as roselle, is used in folk medicine as an anti-inflammatory agent. Urinary tract infection (UTI) is a common problem in long-term care facilities. However, effects of roselle on UTI and renal inflammation remained to be analyzed.
    Aim: Here we surveyed the effect of roselle drink on the prevention of UTI in long-term care facilities and analyzed the anti-inflammatory potential of roselle on lipopolysaccharide (LPS)-induced renal inflammation in mice.
    Materials and methods: Survey questionnaires and clinical observation were applied to evaluate the use of roselle and the incidence of UTI in long-term care facilities. Mice were administrated roselle orally for 7 consecutive days and then challenged with LPS. Anti-renal inflammatory effects of roselle were analyzed by microarray and immunohistochemical staining.
    Results: Clinical observation showed that taking roselle drink in residents with urinary catheters reduced the incidence of UTI in long-term care facilities. Renal inflammation is a key event of UTI. Roselle suppressed LPS-induced nuclear factor-κB (NF-κB) activation in cells and LPS-induced interleukin-1β production in mice a dose-dependent manner. Immunohistochemical staining showed that roselle inhibited LPS-induced NF-κB activation and inflammatory cell infiltration in kidney. Gene expression profiling further showed that roselle suppressed the expression of pro-inflammatory cytokine genes and enzyme genes involved in the production of prostaglandin and nitric oxide. In addition, NF-κB was the main transcription factor involved in the regulation of roselle-regulated gene expression in kidney.
    Conclusions: This is the first report applying clinical observation-guided transcriptomic study to explore the application and mechanism of roselle on UTI. Our findings suggested that roselle drink ameliorated LPS-induced renal inflammation via downregulation of cytokine network, pro-inflammatory product production, and NF-κB pathway. Moreover, this report suggested the potential benefit of roselle drink on UTI.

    Abstract Background: Glycyrrhizin, silymarin, and ursodeoxycholic acid are widely used hepatoprotectants for the treatment of liver disorders, such as hepatitis C virus infection, primary biliary cirrhosis, and hepatocellular carcinoma.
    Purpose: The gene expression profiles of HepG2 cells responsive to glycyrrhizin, silymarin, and ursodeoxycholic acid were analyzed in this study.
    Methods: HepG2 cells were treated with 25 µM hepatoprotectants for 24 h. Gene expression profiles of hepatoprotectants-treated cells were analyzed by oligonucleotide microarray in triplicates. Nuclear factor-κB (NF-κB) activities were assessed by luciferase assay.
    Results: Among a total of 30,968 genes, 252 genes were commonly regulated by glycyrrhizin, silymarin, and ursodeoxycholic acid. These compounds affected the expression of genes relevant various biological pathways, such as neurotransmission, and glucose and lipid metabolism. Genes involved in hepatocarcinogenesis, apoptosis, and anti-oxidative pathways were differentially regulated by all compounds. Moreover, interaction networks showed that NF-κB might play a central role in the regulation of gene expression. Further analysis revealed that these hepatoprotectants inhibited NF-κB activities in a dose-dependent manner.
    Conclusion: Our data suggested that glycyrrhizin, silymarin, and ursodeoxycholic acid regulated the expression of genes relevant to apoptosis and oxidative stress in HepG2 cells. Moreover, the regulation by these hepatoprotectants might be relevant to the suppression of NF-κB activities.
