[PMID: 38906339 DOI: 10.1016/j.jep.2024.118468] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Revised: 06/07/2024] [Accepted: 06/15/2024] [Indexed: 06/23/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Pueraria lobata is essential medicinal and edible homologous plants widely cultivated in Asian countries. Therefore, P. lobata is widely used in the food, health products and pharmaceutical industries and have significant domestic and international market potential and research value. P. lobata has remarkable biological activities in protecting liver, relieving alcoholism, antioxidation, anti-tumor and anti-inflammation in clinic. However, the potential mechanism of ethyl acetate extract of Pueraria lobata after 70% alcohol extraction (APL) ameliorating nonalcoholic fatty liver disease (NAFLD) has not been clarified. AIM OF THE STUDY This study aimed to investigate the ameliorative effect of P. lobata extract on human hepatoma cells and injury in rats, and to evaluate its therapeutic potential for ameliorating NAFLD. METHODS Firstly, the effective part of P. lobata extract was determined as APL by measuring its total substances and antioxidant activity. And then the in vitro and in vivo models of NAFLD were adopted., HepG2 cells were incubated with palmitic acid (PA) and hydrogen peroxide (H2O2). In order to evaluate the effect of APL, Simvastatin and Vitamin C (VC) were used as positive control. Various parameters related to lipogenesis and fatty acid β-oxidation were studied, such as intracellular lipid accumulation, reactive oxygen species (ROS), Western Blot, mitochondrial membrane potential, apoptosis, and the mechanism of APL improving NAFLD. The chemical components of APL were further determined by HPLC and UPLC-MS, and molecular docking was carried out with Keap1/Nrf2/HO-1 pathway related proteins. RESULTS APL significantly reduced lipid accumulation and levels of oxidative stress-related factors in vitro and in vivo. Immunohistochemical、Western Blot and PCR analysis showed that the expressions of Nrf2 and HO-1 were up-regulated in APL treatment. The Nrf2 inhibitor ML385 can block the rescue by APL of cellular oxidative stress and lipid accumulation induced by H2O2 and PA, demonstrating its dependence on Nrf2. UPLC/MS analysis showed that there were 3'-hydroxyl puerarin, puerarin, 3'-methoxy puerarin, daidzein, genistin, ononin, daidzin and genistein. CONCLUSION This study further clarified the mechanism of P. lobata extract in improving NAFLD, which provided a scientific basis for developing new drugs to protect liver injury and laid a solid foundation for developing P. lobata Chinese herbal medicine resources.

Huoxin pill attenuates myocardial infarction-induced apoptosis and fibrosis via suppression of p53 and TGF-β1/Smad2/3 pathways. Biomed Pharmacother 2020; 130:110618. [PMID: 34321167 DOI: 10.1016/j.biopha.2020.110618] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2020] [Revised: 07/27/2020] [Accepted: 08/02/2020] [Indexed: 11/24/2022] Open
Abstract
Huoxin Pill (HXP), a Traditional Chinese Medicine, is used widely to treat patients with coronary heart disease and angina pectoris in China. However, the underlying protective mechanism of HXP on cardiac apoptosis and fibrosis has never been evaluated. Therefore, the aim of this study was to investigate the role of HXP in a myocardial infarction (MI) mouse model. The mice were randomly divided into 3 groups and subjected to surgical ligation of the left anterior descending (LAD) coronary artery or sham surgery (n = 6 for each group) and treated with HXP (50 mg/kg/day) or saline by gavage for 2 weeks. At 2 weeks post MI, we found that HXP significantly enhanced myocardial function and attenuated the increase of heart weight index (HWI) and pathological changes in MI mice. RNA-sequencing and KEGG pathway analyses identified 660 differentially expressed genes and multiple enriched signaling pathways including p53 and TGF-β. In support of these findings, HXP attenuated cardiac apoptosis and decreased p53 and Bax protein expression, while increasing Bcl-2 protein expression in cardiac tissues of MI mice. Furthermore, HXP treatment inhibited cardiac fibrosis and significantly down-regulated TGF-β1 protein expression and Smad2/3 phosphorylation in cardiac tissues. In summary, HXP can improve cardiac function in mice after MI by attenuating cardiac apoptosis and fibrosis partly via supression of the p53/Bax/Bcl-2 and TGF-β1/Smad2/3 pathways.

Zhao JY, Lin W, Zhuang QC, Zhong XY, Peng J, Hong ZF. Bear bile powder inhibits angiogenesis in vivo and in vitro. Chin J Integr Med 2015; 21:369-75. [PMID: 25776838 DOI: 10.1007/s11655-015-2062-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2012] [Indexed: 01/11/2023]
Abstract
OBJECTIVE To evaluate the effect of bear bile powder (BBP) on angiogenesis, and investigate the underlying molecular mechanisms. METHODS A chick embryo chorioallantoic membrane (CAM) assay was used to evaluate the angiogensis in vivo. Human umbilical vein endothelial cells (HUVECs) were treated with 0, 0.25, 0.5, 0.75, and 1.0 mg/mL of BBP for 24, 48 and 72 h, respectively. The 3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay was performed to determine the viability of HUVECs. Cell cycle progression of HUVECs was examined by fluorescence-activated cell sorting (FACS) analysis with propidium iodide staining. HUVEC migration was determined by wound healing method. An ECMatrix gel system was used to evaluate the tube formation of HUVECs. The mRNA and protein expression of vascular endothelial growth factor (VEGF)-A in both HUVECs and HepG2 human cells were examined by reverse transcription-polymerase chain reaction and enzyme linked immunosorbent assay, respectively. RESULTS Compared with the untreated group, BBP inhibited angiogenesis in vivo in the CAM model (P< 0.01). In addition, treatment with 0.25-1 mg/mL of BBP for 24, 48, or 72 h respectively reduced cell viability by 14%-27%, 29%-69% and 33%-91%, compared with the untreated control cells (P< 0.01). Additionally, BBP inhibited the proliferation of HUVECs via blocking the cell cycle G to S progression, compared with the S phase of untreated cells 48.05%± 5.00%, 0.25-0.75 mg/mL BBP reduced S phase to 40.38%± 5.30%, 36.54± 4.50% and 32.13± 3.50%, respectively (Pglt; 0.05). Moreover, BBP inhibited the migration and tube formation of HUVECs, compared with the tube length of untreated cells 100%± 12%, 0.25-0.75 mg/mL BBP reduced the tube length to 62%± 9%, 43%± 5% and 17%± 3%, respectively (p< 0.01). Furthermore, BBP treatment down-regulated the mRNA and protein expression levels of VEGF-A in both HepG2 cells and HUVECs. CONCLUSION BBP could inhibit the angiogenesis by reducing VEGF-A expression, which may, in part, explain its anti-tumor activity.
