In this study, the anti-inflammatory effects of a methanolic extract from the aerial part of Hance (HmAPE) and its underlying mechanisms were investigated. HmAPE demonstrated a significant reduction in nitric oxide production in lipopolysaccharide (LPS)-treated murine macrophage RAW264.7 cells, and HmAPE decreased the protein and mRNA expression of inducible nitric oxide synthase.

Nrf2-mediated protective effect of protein hydrolysates from larvae against oxidative stress-induced hepatotoxicity.

Unlabelled: In this study, we hypothesized that larvae (PBL) protein hydrolysates, which have been previously reported to exhibit strong antioxidant activity, might protect liver cells against oxidative stress-induced injury. Thus, the cytoprotective effects and related mechanisms of PBL hydrolysates were investigated in AML12 liver cells. Among PBL hydrolysates prepared by three different proteases, the PBL flavouryzme hydrolysate showed significantly higher protective effect against HO-induced cytotoxicity than other hydrolysates in AML12 cells.

Protaetia Brevitarsis-Derived Protein Hydrolysate Reduces Obesity-Related Colitis Induced by High-Fat Diet in Mice through Anti-Inflammatory Pathways.

Ulcerative colitis is an inflammatory bowel disease characterized by inflammation in the mucosal and submucosal layers of the colon. Obesity is closely related to the occurrence and progression of colitis. The most plausible mechanism linking obesity and colitis is an excessive adipogenesis-related inflammatory response, which causes mucosal dysfunction.

Flavone and Hydroxyflavones Are Ligands That Bind the Orphan Nuclear Receptor 4A1 (NR4A1).

It was recently reported that the hydroxyflavones quercetin and kaempferol bind the orphan nuclear receptor 4A1 (NR4A1, Nur77) and act as antagonists in cancer cells and tumors, and they inhibit pro-oncogenic NR4A1-regulated genes and pathways. In this study, we investigated the interactions of flavone, six hydroxyflavones, seven dihydroxyflavones, three trihydroxyflavones, two tetrahydroxyflavones, and one pentahydroxyflavone with the ligand-binding domain (LBD) of NR4A1 using direct-binding fluorescence and an isothermal titration calorimetry (ITC) assays. Flavone and the hydroxyflavones bound NR4A1, and their K values ranged from 0.

Elecampane () Root Extract and Its Major Sesquiterpene Lactone, Alantolactone, Inhibit Adipogenesis of 3T3-L1 Preadipocytes.

Recent studies have shown that Nur77 and AMPKα play an important role in regulating adipogenesis and isoalantolactone (ISO) dual-targeting AMPKα and Nur77 inhibits adipogenesis. In this study, we hypothesized that (elecampane) root extract (IHE), which contains two sesquiterpene lactones, alantolactone (ALA) and ISO, as major compounds, might inhibit adipogenesis. Here, we found that ALA and IHE simultaneously target AMPKα and Nur77 and inhibited adipogenic differentiation of 3T3-L1 cells, accompanied by the decreased expression of adipocyte markers.

Plant Alkaloid Tetrandrine Is a Nuclear Receptor 4A1 Antagonist and Inhibits Panc-1 Cell Growth In Vitro and In Vivo.

The orphan nuclear receptor 4A1 (NR4A1) is highly expressed in human pancreatic cancer cells and exerts pro-oncogenic activity. In a previous study, we demonstrated that fangchinoline (FCN), a natural inhibitor of nuclear NR4A1, induces NR4A1-dependent apoptosis in human pancreatic cancer cells. In this study, we evaluated FCN and its structural analogs (berbamine, isotetrandrine, tetrandrine, and tubocurarine) for their inhibitory effects on NR4A1 transactivity, and confirmed that tetrandrine (TTD) showed the highest inhibitory effect in pancreatic cancer cells.

Antiobesity and Hepatoprotective Effects of Protein Hydrolysates Derived from in an Obese Mouse Model.

Background: Obesity induced by excessive nutrients can cause fatty liver and metabolic dysfunction, which leads to hepatic dysfunction and local/systemic inflammatory responses. Previously, we analyzed the antioxidant, antilipotoxicity, and anti-inflammatory effects of protein hydrolysates in vitro. The aim of the present study is to investigate the antiobesity and hepatoprotective effects of protein hydrolysates derived from (PHPB) in an obese mouse model.

In Vitro and In Vivo Protective Effects of Lentil () Extract against Oxidative Stress-Induced Hepatotoxicity.

Excessive oxidative stress plays a role in hepatotoxicity and the pathogenesis of hepatic diseases. In our previous study, the phenolic extract of beluga lentil (BLE) showed the most potent in vitro antioxidant activity among extracts of four common varieties of lentils; thus, we hypothesized that BLE might protect liver cells against oxidative stress-induced cytotoxicity. BLE was evaluated for its protective effects against oxidative stress-induced hepatotoxicity in AML12 mouse hepatocytes and BALB/c mice.

Flavonoids kaempferol and quercetin are nuclear receptor 4A1 (NR4A1, Nur77) ligands and inhibit rhabdomyosarcoma cell and tumor growth.

Background: Flavonoids exhibit both chemopreventive and chemotherapeutic activity for multiple tumor types, however, their mechanisms of action are not well defined. Based on some of their functional and gene modifying activities as anticancer agents, we hypothesized that kaempferol and quercetin were nuclear receptor 4A1 (NR4A1, Nur77) ligands and confirmed that both compounds directly bound NR4A1 with K values of 3.1 and 0.

The Oral Administration of Extract Improves Physical Performance through LDHA Modulation.

Dual targeting of Nur77 and AMPKα by isoalantolactone inhibits adipogenesis in vitro and decreases body fat mass in vivo.

Background: Suppression of adipogenesis has been considered as a potential target for the prevention and treatment of obesity and associated metabolic disorders, and the nuclear receptor 4A1 (NR4A1/Nur77) and AMPKα are known to play important roles during early and intermediate stages of adipogenesis. Therefore, we hypothesized that dual targeting Nur77 and AMPKα would show strong inhibitory effect on adipogenesis.

Methods: We screened a herbal medicine-based small molecule library to identify novel natural compounds dual targeting Nur77 and AMPKα, and the antiadipogenic effects and mechanisms of action of a "hit" compound were studied in 3T3-L1 cells.

Inactivation of the orphan nuclear receptor NR4A1 contributes to apoptosis induction by fangchinoline in pancreatic cancer cells.

Previous studies have demonstrated that the orphan nuclear receptor NR4A1 is overexpressed in human pancreatic cancer and antagonizing this receptor promotes apoptosis and inhibits pancreatic cancer cells and tumor growth. In the present study, we identified fangchinoline, a bisbenzyltetrahydroisoquinoline alkaloid from Stephania tetrandra, as a new inactivator of nuclear NR4A1 and demonstrated that fangchinoline inhibits cell proliferation and induces apoptosis, in part, via the NR4A1-dependent pro-apoptotic pathways in human pancreatic cancer cells. It decreased expression of the antiapoptotic protein survivin by inhibiting Sp1-mediated transcription and induced oxidative stress-mediated endoplasmic reticulum (ER) stress in pancreatic cancer cells.

Apomorphine suppresses TNF-α-induced MMP-9 expression and cell invasion through inhibition of ERK/AP-1 signaling pathway in MCF-7 cells.

Recent studies have shown that dopamine plays an important role in several types of cancer by inhibiting cell growth and invasion via dopamine receptors (DRs), such as dopamine receptor D2. However, the roles of DR agonists in cancer cell growth and invasion remain unclear. In our study, we found that apomorphine (APO), one of the most commonly prescribed DR agonists, inhibited TNF-α-induced matrix metalloprotease-9 (MMP-9) expression and cell invasion in MCF-7 human breast carcinoma cells through DR-independent pathways.
