Abstract
The misuse of fentanyl, and novel synthetic opioids (NSO) in general, has become a public health emergency, especially in the United States. The detection of NSO is often challenged by the limited diagnostic time frame allowed by urine sampling and the wide range of chemically modified analogues, continuously introduced to the recreational drug market. In this study, an untargeted metabolomics approach was developed to obtain a comprehensive “fingerprint” of any anomalous and specific metabolic pattern potentially related to fentanyl exposure. In recent years, in vitro models of drug metabolism have emerged as important tools to overcome the limited access to positive urine samples and uncertainties related to the substances actually taken, the possible combined drug intake, and the ingested dose. In this study, an in vivo experiment was designed by incubating HepG2 cell lines with either fentanyl or common drugs of abuse, creating a cohort of 96 samples. These samples, together with 81 urine samples including negative controls and positive samples obtained from recent users of either fentanyl or “traditional” drugs, were subjected to untargeted analysis using both UHPLC reverse phase and HILIC chromatography combined with QTOF mass spectrometry. Data independent acquisition was performed by SWATH in order to obtain a comprehensive profile of the urinary metabolome. After extensive processing, the resulting datasets were initially subjected to unsupervised exploration by principal component analysis (PCA), yielding clear separation of the fentanyl positive samples with respect to both controls and samples positive to other drugs. The urine datasets were then systematically investigated by supervised classification models based on soft independent modeling by class analogy (SIMCA) algorithms, with the end goal of identifying fentanyl users. A final single-class SIMCA model based on an RP dataset and five PCs yielded 96% sensitivity and 74% specificity. The distinguishable metabolic patterns produced by fentanyl in comparison to other opioids opens up new perspectives in the interpretation of the biological activity of fentanyl.

Abstract
Cancer is a complicated long-term disease due to computable key molecular players involved in aggravating the disease. Among various kinds of cancer, hepatocellular carcinoma (HCC) is the ninth leading cause of cancer. Recently, plant-based products are gaining a lot of attention in the field of research because of their anti-tumor properties. In our previous study, we reported based on in-silico method that bromelain, a cysteine protease extracted from the stem of the pineapple, has high binding affinity with the transcription factors p53 and β-catenin proteins which are key players in controlling the progression of hepatocellular carcinoma. Bromelain, isolated mainly from the stem of Pineapple (Ananas comosus), belongs to the family Bromeliaceae. The present study deals with preclinical analysis of bromelain as an anti-cancer agent and its intracellular effect on the expression of p53 and β-catenin protein. Our study reports cytotoxic activity, cell proliferation, migration, invasion, arrest in the S-phase, and G2/M phase in cell cycle analysis by treating with bromelain in HepG2 cell lines. We also report up-regulation of p53 protein by drug-induced impediment leading to apoptotic process in HepG2 cells and down-regulation of β-catenin protein in HepG2 cells which interferes in β-catenin/TCF-DNA interaction further, down-regulating Wnt genes and suppressing the canonical pathway. Finally, we conclude that bromelain inhibits tumorigenic potential in HepG2 cell lines.

Abstract
Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a key factor in several cardiovascular diseases, as it is responsible for the elevation of circulating low-density lipoprotein cholesterol (LDL-C) levels in blood plasma by direct interaction with the LDL receptor. The development of orally available drugs to inhibit this PCSK9-LDLR interaction is a highly desirable objective. Here, we report the synthesis of naturally occurring moracin compounds and their derivatives with a 2-arylbenzofuran motif to inhibit PCSK9 expression. In addition, we discuss a short approach involving the three-step synthesis of moracin C and a divergent method to obtain various analogs from one starting material. Among the tested derivatives, compound 7 (97.1%) was identified as a more potent inhibitor of PCSK9 expression in HepG2 cells than berberine (60.9%). These results provide a better understanding of the structure-activity relationships of moracin derivatives for the inhibition of PCSK9 expression in human hepatocytes.

Abstract
Green synthesis of metal nanoparticles using plant extracts as capping and reducing agents for the biomedical applications has received considerable attention. Moreover, emergence and spread of multidrug resistance among bacterial pathogens has become a major health concern and lookout for novel alternative effective drugs has gained momentum. In current study, we synthesized gold nanoparticles using the seed extract of Trachyspermum ammi (TA-AuNPs), assessed its efficacy against drug resistant biofilms of Listeria monocytogenes and Serratia marcescens, and evaluated its anticancer potential against HepG2 cancer cell lines. Microwave-assisted green synthesis of gold nanoparticles was carried out and characterization was done using UV-vis spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), and dynamic light scattering (DLS). Most nanoparticles were observed as spherical and spheroidal with few anisotropies with an average crystalline size of 16.63 nm. Synthesized TA-AuNPs demonstrated significant biofilm inhibitory activity against L. monocytogenes (73%) as well as S. marcescens (81%). Exopolysaccharide (EPS), motility, and CSH, key elements that facilitate the formation and maintenance of biofilm were also inhibited significantly at the tested sub-minimum inhibitory concentrations (sub-MICs). Further, TA-AuNPs effectively obliterated preformed mature biofilms of S. marcescens and L. monocytogenes by 64% and 58%, respectively. Induction of intracellular ROS production in TA-AuNPs treated bacterial cells could be the plausible mechanism for the reduced biofilm formation in test pathogens. Administration of TA-AuNPs resulted in the arrest of cellular proliferation in a concentration-dependent manner. TA-AuNPs decrease the intracellular GSH in HepG2 cancer cell lines, cells become more prone to ROS generation, hence induce apoptosis. Thus, this work proposes a new eco-friendly and rapid approach for fabricating NPs which can be exploited for multifarious biomedical applications.

Abstract
Morus australis distributed widely in China has high value in food and agriculture. Twelve phenolic compounds were isolated and identified as major constituents of M. australis root from Shaanxi province, China, while the protective effect of M. australis root on liver injury has never been determined in detail. In this study, the hepatoprotective ability of M. australis root was investigated in vivo and in vitro. The ethanol-water extract prepared from M. australis root showed protection on alcohol-induced liver damage in mice by decreasing the levels of serum alanine aminotransferase, aspartate transaminase, triacylglycerol and malondialdehyde, and by increasing glutathione contents. Furthermore, among 12 major constituents of M. australis root, 10 flavonoids (especially 1) showed protection against carbon tetrachloride (CCl4 )-intoxicated HepG2 cell lines by decreased lactic dehydrogenase levels. In addition a validated HPLC-DAD method was established for the quantitative analysis of 10 flavonoids in the bioactive extract. PRACTICAL APPLICATIONS: Our results showed that M. australis root extract significantly alleviated the liver damage in mice. Ten flavonoids from the root of this plant exhibited protection on CCl4 -intoxicated HepG2 cell lines. This study suggests that Morus australis root has hepatoprotective potential as a promising supplement for the prevention and treatment of liver diseases.

Abstract
In this study, fourteen ingenane-type and nine jatrophane-type diterpenoids were isolated from Euphorbia kansui, including seven undescribed compounds. Kansuingenol A-C have the 6,7-vicinal diol moiety, and Kansuijatrophanol A and B possess the 11,12-vicinal diol moiety, both of which are rarely reported. 3,4-(Methylenedioxy) cinnamyl moiety was found for the first time in jatrophane-type diterpenoids, as shown in Kansuijatrophanol C and D. The absolute configurations of seven undescribed compounds have been analyzed and assigned by the modified Mosher's method, Mo2(OAc)4-induced circular dichroism (ICD) method, and CD exciton chirality method. All compounds were screened for their antiproliferative effects against HepG2, MCF-7 and DU145 cell lines. Regarding the HepG2 cells, Kansuijatrophanol C exhibited the most promising inhibition with the IC50 value of 9.47 ± 0.31 μM. Regarding the MCF-7 and DU145 cells, Kansuijatrophanol D exhibited the most promising inhibition with the IC50 values of 6.29 ± 0.18 and 4.19 ± 0.32 μM, respectively.

Abstract
Nowadays, the synthesis and characterization of gold nanoparticles (AuNPs) from plant based extracts and effects of their anticancer have concerned an important interest. Marsdenia tenacissima (MT), a conventional Chinese herbal medicine, has long been used for thousands of years to treat tracheitis, asthma, rheumatism, etc. In this present study, we optimize the reaction of parameters to manage the nanoparticle size, which was categorized by high-resolution transmission electron microscopy (HR-TEM). A different characterization method, for example, UV-visible spectroscopy (UV-vis), fourier-transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD) were performed to consider the synthesized AuNPs getting from the MT leaf extract. The MT-AuNPs were analyzed for their cytotoxicity property against HepG2 cells by MTT analysis. The apoptosis was evaluated by using reactive oxygen species (ROS), migration assay, mitochondrial membrane potential (MMP) and apoptotic protein expression. Interestingly, the findings of our study observed the cytotoxicity effect of synthesized MT-AuNPs at a concentration of 59.62 ± 4.37 μg after 24 hrs treatment. Apoptosis was induced by the MT-AuNPs with enhanced ROS, changed MMP and inhibit the migration assay. Finally, the apoptosis was confirmed by the considerable up-regulation of Bax, caspase-9 and caspase-3, while the anti-apoptotic protein expressions of Bcl-2 and Bcl-XL were down-regulated. Although, in this studies, we evaluated the characterization, synthesis and anticancer action of gold nanoparticles from MT (MT-AuNPS) helpful for liver cancer therapeutics.

Abstract
OBJECTIVE To investigate the effect of nuclear receptor Rev-erbβ knockout on proliferation and migration ability of human hepatocellular carcinoma cell line HepG2. METHODS -The Rev-erbβ gene knockout HepG2 cell line was abtained by CRISPR/Cas9 genome editing technique with specific DNA modification of the target gene. The Rev-erbβ gene targeting vectors were co-transfected into HepG2 cells. Through cloning and screening, the Rev-erbβ gene knockout HepG2 cell line was constructed, PCR, sequencing and Western blot methods were carried out for the identification of the Rev-erbβ gene knockout HepG2 cell line. The expression level of tumor migration and invasion-associated gene in Rev-erbβ gene knockout cell was determined by real-time quantitative PCR (qRT-PCR) and was compared with normal cell as control.MTT, cell scratch and Transwell experiments were conducted in order to explore the effect of Rev-erbβ gene on HepG2 cell's ability of proliferation, migration and invasion. RESULTS A Rev-erbβ gene knockout monoclonal cell line, which was identified by PCR, sequencing and Western blot, was successfully constructed and named HepG2 C5 (Rev-erbβ -/-). qRT-PCR results showed that Rev-erbβ knockout resulted in up-regulation of matrix metalloproteinase-2 (MMP2), matrix metalloproteinase-9 (MMP9) and extracellular matrix protein-1 (ECM1) gene expression (P < 0.05) and down-regulation of E-cadherin (CDH1) gene expression (P=0.05).Results of MTT, cell scratch and transwell experiments showed that HepG2 C5 had stronger proliferation, migration and invasion ability than control cells (P < 0.05). CONCLUSION Rev-erbβ gene knockout could change the expression of migration and adhesion-associated genes in HepG2 cell, and then affect the proliferation, migration and invasion ability of HepG2 cells.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The roots of Rubia yunnanensis Diels (Rubiaceae) have been used as an alternative for Rubia cordifolia for the treatment of various diseases including cardiovascular disease and metabolic disease for a long history in traditional Chinese medicine. To evaluate antihyperlipidemic activity of the roots of Rubia. yunnanensis Diels and to identify active compounds from the active fraction. MATERIAL AND METHODS Antihyperlipidemic effects of extract and compounds of the roots of Rubia yunnanensis were studied in HepG2 cells and in vivo model in olive oil-loaded mice. The isolation of compounds was conducted using various chromatographic methods and the structures of the isolated compounds were elucidated by NMR and MS techniques. RESULTS Methanol extract and ethyl acetate fraction of Rubia yunnanensis potently decreased the triglycerides accumulation in HepG2 cells and the methanol extract of Rubia yunnanensis (125, 250 and 500 mg/kg) significantly inhibited the TG elevation in a dose dependent manner in olive oil-loaded mice. Through various chromatographic methods, twenty-three compounds (1-23) were isolated in which arborinane-type triterpenoids and a free anthraquinone potently inhibited TG levels in HepG2 cells. CONCLUSION Arborinane-type triterpenoids, especial rubiarbonone C (16) and an anthraquinone, 2-methyl-1, 3, 6-trihydroxy-9, 10-anthraquinone (MTHA) (22) were identified as the main active compounds responsible for antihyperlipidemic activity. Based on these findings, we proposed that the extract of Rubia yunnanensis and its active components, arborinane-type triterpenoids and the free anthraquinone might be beneficial in the treatment and prevention of hyperlipidemic disease.

Abstract
Photodynamic therapy (PDT) is a promising new modality for the treatment of cancer through generation of reactive oxygen species (ROS). In this work, human liver adenocarcinoma cells HepG2 were treated with zinc oxide nanoparticles (ZnO-NPs), metal-doped-ZnO-NPs: Fe-ZnO-NPs Ag-ZnO-NPs, Pb-ZnO-NPs, and Co-ZnO-NPs, Silica-coated ZnO-NPs, titanium dioxide nanoparticles (TiO2-NPs), titanium dioxide nano-tubes (TiO2-NTs) and ZnO-NPs/TiO2-NTs nanocomposite under UV irradiation. Doxorubicin was used as a standard drug. The results demonstrated that the ZnO-NPs, Fe-ZnO-NPs, Ag-ZnO-NPs, Pb-ZnO-NPs, and Co-ZnO-NPs showed cytotoxicity against HepG2 cells, with the median growth inhibitory concentrations (IC50) 42.60, 37.20, 45.10, 77.20 and 56.50 μg/ml, respectively, as compared to doxorubicin (IC50: 20.10 μg/ml). Treatment of the cancer cells with ZnO-NPs, Fe-ZnO-NPs, Ag-ZnO-NPs, Pb-ZnO-NPs, and Co-ZnO-NPs resulted in a significant increase in the activity of SOD and the levels of H2O2 and NO than those of control, accompanied with a significant decrease in the activity of CAT and GSH-Px. Also, depletion of reduced GSH, total protein and nucleic acids levels was observed. In conclusion, metal-doped ZnO-NPs may induce antiproliferative effect on HepG2 cells under UV-irradiation due to generation of ROS. Therefore, they could be included in modern clinical trials after in vivo more investigations, using photodynamic therapy technique.
