Park HJ, Jeong JH, Choi YH, Park SH. Hexane Fraction of Adenophora triphylla var. japonica Root Extract Inhibits Angiogenesis and Endothelial Cell-Induced Erlotinib Resistance in Lung Cancer Cells. Molecules 2024; 29:597. [PMID: 38338342 PMCID: PMC10856037 DOI: 10.3390/molecules29030597] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Revised: 01/20/2024] [Accepted: 01/24/2024] [Indexed: 02/12/2024] Open
Abstract
The aim of this study was to investigate the anti-angiogenic effects of the hexane fraction of Adenophora triphylla var. japonica root extract (HAT) and its influence on the development of erlotinib resistance in human lung cancer cells. HAT significantly reduced the migration, invasion, and tube formation of human umbilical vein endothelial cells (HUVECs). The phosphorylation levels of vascular endothelial growth factor receptor 2 (VEGFR2) and its downstream molecules were decreased via HAT, indicating its anti-angiogenic potential in endothelial cells (ECs). A docking analysis demonstrated that β-sitosterol and lupeol, representative components of HAT, exhibit a high affinity for binding to VEGFR2. In addition, conditioned media from HAT-pretreated H1299 human lung cancer cells attenuated cancer-cell-induced chemotaxis of HUVECs, which was attributed to the decreased expression of angiogenic and chemotactic factors in H1299 cells. Interestingly, co-culture of erlotinib-sensitive PC9 human lung cancer cells with HUVECs induced erlotinib resistance in PC9 cells. However, co-culture with HAT-pretreated HUVECs partially restored the sensitivity of PC9 cells to erlotinib. HAT inhibited the development of erlotinib resistance by attenuating hepatocyte growth factor (HGF) production by ECs. Taken together, our results demonstrate that HAT exerts its anticancer effects by regulating the crosstalk between ECs and lung cancer cells.

Genes (Basel) 2023; 15:58. [PMID: 38254948 PMCID: PMC10815912 DOI: 10.3390/genes15010058] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Revised: 12/26/2023] [Accepted: 12/27/2023] [Indexed: 01/24/2024] Open
Abstract
Adenophora triphylla is an important medicinal and food plant found in East Asia. This plant is rich in secondary metabolites such as triterpenoid saponin, and its leaves can develop into different types, such as round and linear, depending on the origin of germination even within the same species. Despite this, few studies have comprehensively characterized the development processes of different leaf types and triterpenoid saponin pathways in this plant. Herein, we provide the first report of a high-quality genome assembly of A. triphylla based on a combination of Oxford Nanopore Technologies and Illumina sequencing methods. Its genome size was estimated to be 2.6 Gb, and the assembled genome finalized as 2.48 Gb, containing 57,729 protein-coding genes. Genome completeness was assessed as 95.6% using the Benchmarking Universal Single-Copy Orthologs score. The evolutionary divergence of A. triphylla was investigated using the genomes of five plant species, including two other species in the Campanulaceae family. The species A. triphylla diverged approximately 51-118 million years ago from the other four plants, and 579 expanded/contracted gene families were clustered in the Gene Ontology terms. The expansion of the β-amyrin synthase (bAS) gene, a key enzyme in the triterpenoid saponin pathway, was identified in the A. triphylla genome. Furthermore, transcriptome analysis of the two leaf types revealed differences in the activity of starch, sucrose, unsaturated fatty acid pathways, and oxidoreductase enzymes. The heat and endoplasmic reticulum pathways related to plant stress were active in the development of round type leaf, while an enhancement of pyrimidine metabolism related to cell development was confirmed in the development of the linear type leaf. This study provides insight into the evolution of bAS genes and the development of different leaf types in A. triphylla.

Abstract
The aim of this study was to investigate the anticancer effect of Adenophora triphylla var. japonica (AT) root extract on human non-small cell lung cancer (NSCLC) cells and the mechanism involved in such effect. Among three fractions of AT root extract, hexane fraction (HAT) significantly decreased the proliferation of NSCLC cells. Besides, HAT treatment dose-dependently inhibited colony formation of NSCLC cells. These effects were associated with apoptosis induction evidenced by increased chromatin condensation, accumulation of sub-G1 DNA content and annexin V-positive cells, and enhanced expression of apoptotic proteins, including cleaved-caspases and cleaved-poly (ADP-ribose) polymerase (PARP). Notably, phosphorylation levels of signal transducer and activator of transcription 3 (STAT3) and Src were decreased by HAT. Transfection with STAT3 or Src for constitutive activation reversed the anti-proliferative effect of HAT on H1299 cells. Taken together, our findings suggest that HAT-induced apoptosis in NSCLC cells is mediated by inhibition of Src/STAT3 pathway.

Abstract
Adenophora stricta Miq. (Campanulaceae family) is a traditional herb used for relieving cough and phlegm in East Asia. This study explored the effects of A. stricta root extract (AsE) in ovalbumin (OVA)-induced allergic asthma and lipopolysaccharide (LPS)-stimulated macrophages. Administration of 100-400 mg/kg AsE dose-dependently decreased pulmonary congestion and suppressed the reduction of alveolar surface area in mice with OVA-mediated allergic asthma. Histopathological analysis of lung tissue and cytological analysis of bronchioalveolar lavage fluid showed that AsE administration significantly attenuated inflammatory cell infiltration into the lungs. In addition, AsE also alleviated OVA-specific immunoglobulin E, interleukin (IL)-4, and IL-5 production, which are essential for OVA-dependent activation of T helper 2 lymphocytes. In Raw264.7 macrophage cells, AsE significantly blocked nitric oxide, tumor necrosis factor-α, IL-1β, IL-6, and monocyte chemoattractant factor-1 production in response to LPS. Results from an immunoblot assay revealed that AsE inhibited the phosphorylation of c-jun N-terminal kinase, inhibitory-κB kinase α/β, and p65 in LPS-stimulated cells. Furthermore, 2-furoic acid, 5-hydroxymethylfurfural, and vanillic acid 4-β-D-glucopyranoside in AsE were shown to inhibit the production of proinflammatory mediators by LPS. Taken together, the present results suggest that A. stricta root will be a useful herb for relieving allergic asthma through managing airway inflammation.

Abstract
Chronic exposure of particulate matter of less than 2.5 μm (PM2.5) has been considered as one of the major etiologies for various respiratory diseases. Adenophora stricta Miq. is a medicinal herb that has been used for treating respiratory diseases in East Asia. The present study investigated the effect of A. stricta root extract (AsE) on PM2.5-induced lung injury in mice. Oral administration of 100-400 mg/kg AsE for 10 days significantly reduced the PM2.5-mediated increase in relative lung weight, but there was no difference in body weight with AsE administration. In addition, AsE dose-dependently decreased congested region of the lung tissue, prevented apoptosis and matrix degradation, and alleviated mucus stasis induced by PM2.5. Moreover, cytological analysis of bronchioalveolar lavage fluid revealed that AsE significantly inhibited the infiltration of immune cells into the lungs. Consistently, AsE also decreased expression of proinflammatory cytokines and chemokines in lung tissue. Furthermore, AsE administration blocked reactive oxygen species production and lipid peroxidation through attenuating the PM2.5-dependent reduction of antioxidant defense system in the lungs. Therefore, A. stricta root would be a promising candidate for protecting lung tissue from air pollution such as PM2.5.

Abstract
Aim Antioxidant therapy for with vitamin E appears to be effective for the treatment of nonalcoholic fatty liver disease (NAFLD). However, the mechanism of action and optimal therapeutic dosage is unclear. The present study was undertaken to examine whether the effects of α‐tocopherol (α‐Toc) on NAFLD are dose‐dependent in a diet‐induced obese model. Methods Male mice were fed standard chow, high‐fat (HF) diet, HF diet with low‐dose, or with high dose of α‐Toc supplementation. Histological findings, triglyceride content, and the levels of protein expression related to fatty acid synthesis/oxidation such as carnitine palmitoyltransferase I (CPT‐1) of liver were evaluated. In addition, 2‐tetradecylglycidic acid (TDGA), a CPT‐1 inhibitor, was administered to mice fed HF diet with low‐dose of α‐Toc. Finally, HepG2 cells in fat‐loaded environment were treated with 0–50 μM α‐Toc. Results Treatment of low‐dose of α‐Toc decreased HF‐induced hepatic fat accumulation, but this finding was not observed in treatment of high dose of α‐Toc. HF‐induced reduction of CPT‐1 was attenuated with low‐dose of α‐Toc but not with high dose of α‐Toc. TDGA suppressed the improvement of histological findings in liver induced by low‐dose of α‐Toc treatment. CPT‐1 expression in HepG2 cells increased in response to low‐dose of α‐Toc, but not in high dose. Conclusions Dual action of α‐Toc on CPT‐1 protein levels was observed. The effect of vitamin E on NAFLD may be not be dose‐dependent.

Abstract
Standardized animal models represent one of the most valuable tools available to understand the mechanism underlying the metabolic syndrome (MetS) and to seek for new therapeutic strategies. However, there is considerable variability in the studies conducted with this essential purpose. This review presents an updated discussion of the most recent studies using diverse experimental conditions to induce MetS in rodents with unbalanced diets, discusses the key findings in metabolic outcomes, and critically evaluates what we have been learned from them and how to advance in the field. The study includes scientific reports sourced from the Web of Science and PubMed databases, published between January 2013 and June 2020, which used hypercaloric diets to induce metabolic disorders, and address the impact of the diet on metabolic parameters. The collected data are used as support to discuss variables such as sex, species, and age of the animals, the most favorable type of diet, and the ideal diet length to generate metabolic changes. The experimental characteristics propose herein improve the performance of a preclinical model that resembles the human MetS and will guide researchers to investigate new therapeutic alternatives with confidence and higher translational validity.

Abstract
Diet-induced obesity (DIO) has been shown to increase DNA methyltransferases (DNMTs) expression and DNMTs binding at obesity-associated genes. Natural compounds have the potential to reverse obesity-associated gene expression via the regulation of DNA methylation. The objective of this study was to determine the effect of health promoting compounds of flaxseed on DNMTs and obesity-associated gene expression and weight gain. Sixty C57BL/6J male mice were randomly assigned into one of the following diet groups and fed for eight weeks: 45% kcal fat; 45% kcal fat+10% whole flaxseed; 45% kcal fat+6% defatted flaxseed; 45% kcal fat+4% flaxseed oil; and 16% kcal fat. DNMT1, DNMT3a, DNMT3b, leptin, and peroxisome proliferator-activated receptor (PPAR)-α expressions in adipose and muscle tissues were determined by real-time PCR. The health promoting compounds of flaxseed affected selected gene expression and attenuated weight gain. Further research is needed to identify the specific mechanisms modulating leptin or PPAR-α expression during DIO development.

Abstract
To investigate the anti-obesity potential of Antidesma bunius L. (MM), a Thai local fruit which is named "Mao Luang," we have focused on the effects on pancreatic α-amylase and lipase enzyme activity and on adipocyte life cycle using the 3T3-L1 cell line as a model. In addition, the phytochemical composition and anti-oxidation potential were also analyzed using HPLC-PDA UV and colorimetric methods. The ethanolic extract of MM fruits prepared by a maceration method was used in the experiments. MM extract, yield 12.08% w/w, is composed primarily of phenolics and anthocyanins as the major phytochemicals, among which, gallic acid, catechin, anthocyanin-3-glucoside, and protocatechuic acid were initially identified. In addition, susceptibly inhibitory effects on oxidation in a DPPH assay; on lipase enzyme activity rather than amylase enzyme; and on adipocyte adipogenesis of MM were demonstrated. Interestingly, a concentration-dependent bi-modular manner of activity on adipocyte adipogenesis was discovered, whereby a significant anti-adipogenic effect was demonstrated at high concentration, whilst low concentrations of MM showed adipogenic induction. Lipolytic induction was manifested. Conclusively, the ethanolic MM extract was discovered to be a potential anti-obesity agent contributed by inhibitory effects on lipase enzyme and anti-differentiation and -adipogenesis in adipocytes which significantly correlated to the total phenolics content, as well as anti-oxidation as the mechanism of action. Nevertheless, to achieve effective application, further investigation in in vivo models should be considered.

[PMID: 31683541 PMCID: PMC6918293 DOI: 10.3390/plants8110466] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/17/2019] [Revised: 10/21/2019] [Accepted: 10/29/2019] [Indexed: 11/17/2022]
Abstract
Adenophora triphylla var. japonica Hara is a highly valued medicinal plant that is used to treat or prevent bronchitis, cough, cancer, and obesity. However, there has been no study on the production of Adenophora triphylla var. japonica Hara seedlings in a closed-type plant production system (CPPS). This study was conducted to examine the growth characteristics of Adenophora triphylla var. japonica Hara seedlings as affected by different growing media. The seeds were sown on a 128-cell plug tray filled with urethane sponges (US), LC grow foam (LC), rockwool (RW), or terra-plugs (TP). The seedlings were cultured for a duration of 54 days under temperature 25 ± 1°C, a photoperiod of 12/12 h (light/dark), and light intensity of 180 µmol·m−2·s−1 photosynthetic photon flux density provided by RB LEDs (red:blue = 8:2) in a closed-type plant production system (CPPS). The germination rate of Adenophora triphylla var. japonica Hara was significantly highest in the TP. Also, seedling shoot growth indicators of plant height, leaf length, leaf width, number of leaves, fresh weight (FW), and dry weight (DW) of the shoot, and leaf area were markedly the greatest in the TP and the lowest in the US. The SPAD (soil-plant analysis development) value was higher in the TP and US than in the LC or RW. In addition, the seedling root growth characteristics of total root length, root surface area, root volume, and number of root tips were significantly greatest in the TP. Moreover, the maximum root diameter, FW and DW of roots were the greatest in the TP. In conclusion, the results suggest that TP are viable for the growth development of Adenophora triphylla var. japonica Hara seedlings.

Supplementary Light Source Affects Growth, Metabolism, and Physiology of Adenophora triphylla (Thunb.) A.DC. Seedlings. BIOMED RESEARCH INTERNATIONAL 2019; 2019:6283989. [PMID: 31205942 PMCID: PMC6530224 DOI: 10.1155/2019/6283989] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/04/2019] [Revised: 03/12/2019] [Accepted: 03/21/2019] [Indexed: 12/31/2022]
Abstract
Adenophora triphylla (Thunb.) A.DC., a well-known herbaceous medicinal species, has been reported to protect against human obesity, cancer, and inflammation. Supplementary lighting is a practical strategy to improve crop quality, especially at a propagation stage. However, there has been no study available on the optimal supplementary light source for the commercial production of A. triphylla seedlings. In this study, plug seedlings were cultivated in a greenhouse for four weeks under an average daily light intensity of 490 μmol·m−2·s−1 PPFD coming from the sun and a supplemental lighting (16 h per day) at 120 μmol·m−2·s−1 PPFD provided by high pressure sodium (HPS), metal halide (MH), far-red (FR) light, white LED (red: green: blue = 2:4:3, LED-w), or mixed (red: green: blue = 4:1:4) LED (LED-mix). The results showed that LED-mix, with a higher percentage of red and blue light, substantially promoted seedling growth compared to other treatments by increasing stem diameter, biomass, specific leaf weight, and root to shoot ratio. The LED-mix also promoted accumulation of soluble sugar, starch, and chlorophyll in the tissue and increased contents of total phenols and flavonoids. Moreover, stomata density and pore area per leaf area under the LED-mix were remarkably greater than those under other treatments. Furthermore, the Western blot analysis revealed that the expression of photosynthetic protein, D1, was notably enhanced by the LED-mix as compared with other light sources. In addition, the LED-mix alleviated the oxidative damage of seedlings by improving enzymatic and nonenzymatic antioxidant systems. Collectively, these results suggest that the LED-mix was the optimal supplementary light source for the production of highest quality A. triphylla seedlings.

Abstract
Adenophora triphylla (Thunb.) A.DC., three-leaf lady bell, is an important medicinal plant used against cancers and obesity. It has been well-established that the temperature regime affects plant growth and development in many ways. However, there is no study available correlating the growth of A. triphylla seedlings with different day and night temperature regimes. In order to find an optimal temperature regime, growth and physiology were investigated in A. triphylla plug seedlings grown in environment-controlled chambers at different day and night temperatures: 20/20 °C (day/night) (TA), 25/15 °C (TB), and 20/15 °C (TC). The seedlings in plug trays were grown under a light intensity of 150 μmol·m−2·s−1 PPFD (photosynthetic photon flux density) provided by white LEDs, a 70% relative humidity, and a 16 h (day)/8 h (night) photoperiod for six weeks. The results showed that the stem diameter, number of roots, and biomass were significantly larger for seedlings in TB than those in TA or TC. Moreover, the contents of total flavonoid, total phenol, and soluble sugar in seedlings grown in TB were markedly higher than those in seedlings in the other two treatments. Soluble protein content was the lowest in seedlings in TC, while starch content was the lowest in seedlings grown in TA. Furthermore, seedlings grown in TB showed significantly lower activities of antioxidant enzymes such as superoxide dismutase, catalase, ascorbate peroxidase, and guaiacol peroxidase. Native PAGE (polyacrylamide gel electrophoresis) analysis further proved low activities of antioxidant isozymes in TB treatment. Meanwhile, the lowest content of hydrogen peroxide was observed in seedlings grown in TB. In conclusion, the results suggested that the 25/15 °C (day/night) temperature regime is the most suitable for the growth and physiological development of A. triphylla seedlings.

Blueberry polyphenols extract as a potential prebiotic with anti-obesity effects on C57BL/6 J mice by modulating the gut microbiota. J Nutr Biochem 2018; 64:88-100.

Abstract
Polyphenols are known for their various health benefits. Blueberries are dietary sources of polyphenols with reported health benefits. However, the role of blueberry polyphenols in alleviating obesity is not completely understood. This study investigated the potential positive effect of blueberry polyphenol extract (PPE) on high-fat diet (HFD)-induced obesity in C57BL/6 J mice by modulation of the gut microbiota. Four-week-old C57BL/6 J mice were fed a normal-fat diet or HFD with or without PPE or Orlistat for 12 weeks. Mice fed HFD exhibited increased body weight and adipose tissue weight and disordered lipid metabolism. In contrast, PPE inhibited body weight gain and returned lipid metabolism to normal. Furthermore, 16S rRNA gene sequencing of the fecal microbiota suggested that PPE changed the composition of the gut microbiota in C57BL/6 J mice and modulated specific bacteria such as Proteobacteria, Deferribacteres, Actinobacteria, Bifidobacterium, Desulfovibrio, Adlercreutzia, Helicobacter, Flexispira, and Prevotella. Orlistat also improved obesity and metabolic alterations of HFD mice and modulated the composition of the gut microbiota. Our findings suggest that PPE, as a potential prebiotic agent, influences the gut microbiota to positively affect HFD-induced obesity in C57BL/6 J mice.

Abstract
OBJECTIVE To investigate the anti-obesity activity and the action mechanism of the roots of Adenophora triphylla var. japonica extract (ATE) in high-fat diet (HFD)-induced obese mice and 3T3-L1 adipocytes. METHODS The roots of Adenophora triphylla were extracted with 70% ethanol. To demonstrate the compounds, linoleic acid was analyzed by using gas chromatography; and the anti-obesity effects and possible mechanisms of ATE were examined in 3T3-L1 adipocytes and HFD-induced obese mice. RESULTS Treatment with ATE inhibited the lipid accumulation without cytotoxicity in 3T3-L1 adipocytes. Furthermore, 200 and 400 mg/kg ATE treatment significantly decreased the body weight gain, white adipose tissues (WATs) weight and plasma triglyceride level, while 100 and 200 mg/kg ATE treatment increased the plasma high-density lipoprotein cholesterol level in the HFD-induced obese mice, as compared with the HFD group. Treatment with 200 and 400 mg/kg ATE also lowered the size of adipocytes in adipose tissue and reduced the lipid accumulation in liver. ATE treatment showed significantly lower expression level of adipogenesis-related proteins, such as peroxisome proliferator-activated receptor γ, fatty acid binding protein (aP2), fatty acid synthase in 3T3-L1 adipocytes; and furthermore, decreased peroxisome proliferator-activated receptor γ, aP2, fatty acid synthase, sterol regulatory element binding protein-1c, and lipoprotein lipase mRNA expression levels in WAT of the HFD-induced obese mice. CONCLUSIONS These results suggested that the ATE has an anti-obesity effect, which may be elicited by regulating the expression of adipogenesis and lipogenesis-related genes and proteins in adipocytes and WAT of the HFD-induced obese mice.
