Abstract
Liver cancer ranks third globally among causes of cancer-related deaths, posing a significant public health challenge. However, current treatments are inadequate, prompting a growing demand for novel, safe, and effective therapies. Natural products (NPs) have emerged as promising candidates in drug development due to their diverse biological activities, low toxicity, and minimal side effects. This paper begins by reviewing existing treatment methods and drugs for liver cancer. It then summarizes the therapeutic effects of NPs sourced from various origins on liver cancer. Finally, we analyze the potential mechanisms of NPs in treating liver cancer, including inhibition of angiogenesis, migration, and invasion; regulation of the cell cycle; induction of apoptosis, autophagy, pyroptosis, and ferroptosis; influence on tumor metabolism; immune regulation; regulation of intestinal function; and regulation of key signaling pathways. This systematic review aims to provide a comprehensive overview of NPs research in liver cancer treatment, offering a foundation for further development and application in pharmaceuticals and functional foods.

Virus Res 2024; 339:199260. [PMID: 37923169 PMCID: PMC10661853 DOI: 10.1016/j.virusres.2023.199260] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 10/30/2023] [Accepted: 10/30/2023] [Indexed: 11/07/2023]
Abstract
Porcine epidemic diarrhea (PED) is a contagious intestinal disease caused by α-coronavirus porcine epidemic diarrhea virus (PEDV). At present, no effective vaccine is available to prevent the disease. Therefore, research for novel antivirals is important. This study aimed to identify the antiviral mechanism of Veratramine (VAM), which actively inhibits PEDV replication with a 50 % inhibitory concentration (IC50) of ∼5 µM. Upon VAM treatment, both PEDV-nucleocapsid (N) protein level and virus titer decreased significantly. The time-of-addition assay results showed that VAM could inhibit PEDV replication by blocking viral entry. Importantly, VAM could inhibit PEDV-induced phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) activity and further suppress micropinocytosis, which is required for PEDV entry. In addition, PI3K inhibitor LY294002 showed anti-PEDV activity by blocking viral entry as well. Taken together, VAM possessed anti-PEDV properties against the entry stage of PEDV by inhibiting the macropinocytosis pathway by suppressing the PI3K/Akt pathway. VAM could be considered as a lead compound for the development of anti-PEDV drugs and may be used during the viral entry stage of PEDV infection.

The mechanism of action of safflower total flavonoids in the treatment of endometritis caused by incomplete abortion based on network pharmacology and 16S rDNA sequencing. JOURNAL OF ETHNOPHARMACOLOGY 2023:116639. [PMID: 37201664 DOI: 10.1016/j.jep.2023.116639] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/11/2022] [Revised: 05/10/2023] [Accepted: 05/14/2023] [Indexed: 05/20/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Safflower is a traditional Chinese medicine used for treating gynaecological diseases. However, its material basis and mechanism of action in the treatment of endometritis induced by incomplete abortion are still unclear. AIM OF THE STUDY This study aimed to reveal the material basis and mechanism of action of safflower in the treatment of endometritis induced by incomplete abortion through comprehensive methods, including network pharmacology and 16S rDNA sequencing. MATERIALS AND METHODS Network pharmacology and molecular docking methods were used to screen the main active components and potential mechanisms of action of safflower in the treatment of endometritis induced by incomplete abortion in rats. A rat model of endometrial inflammation by incomplete abortion was established. The rats were treated with safflower total flavonoids (STF) based on forecasting results, serum levels of inflammatory cytokines were analysed, and immunohistochemistry, Western blots, and 16S rDNA sequencing were performed to investigate the effects of the active ingredient and the treatment mechanism. RESULTS The network pharmacology prediction results showed 20 active components with 260 targets in safflower, 1007 targets related to endometritis caused by incomplete abortion, and 114 drug-disease intersecting targets, including TNF, IL6, TP53, AKT1, JUN, VEGFA, CASP3 and other core targets, PI3K/AKT, MAPK and other signalling pathways may be closely related to incomplete abortion leading to endometritis. The animal experiment results showed that STF could significantly repair uterine damage and reduce the amount of bleeding. Compared with the model group, STF significantly down-regulated the levels of pro-inflammatory factors (IL-6, IL-1β, NO, TNF-α) and the expression of JNK, ASK1, Bax, caspase3, and caspase11 proteins. At the same time, the levels of anti-inflammatory factors (TGF-β and PGE2) and the protein expression of ERα, PI3K, AKT, and Bcl2 were up-regulated. Significant differences in the intestinal flora were seen between the normal group and the model group, and the intestinal flora of the rats was closer to the normal group after the administration of STF. CONCLUSIONS The characteristics of STF used in the treatment of endometritis induced by incomplete abortion were multi-targeted and involved multiple pathways. The mechanism may be related to the activation of the ERα/PI3K/AKT signalling pathway by regulating the composition and ratio of the gut microbiota.

Front Genet 2023; 14:1023433. [PMID: 36741317 PMCID: PMC9895797 DOI: 10.3389/fgene.2023.1023433] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2022] [Accepted: 01/09/2023] [Indexed: 01/22/2023] Open
Abstract
Veratrum mengtzeanum is the main ingredient for Chinese folk medicine known as "Pimacao" due to its unique alkaloids. A diverse class of plant-specific metabolites having key pharmacological activities. There are limited studies on alkaloid synthesis and its metabolic pathways in plants. To elucidate the alkaloid pathway and identify novel biosynthetic enzymes and compounds in V. mengtzeanum, transcriptome and metabolome profiling has been conducted in leaves and roots. The transcriptome of V. mengtzeanum leaves and roots yielded 190,161 unigenes, of which 33,942 genes expressed differentially (DEGs) in both tissues. Three enriched regulatory pathways (isoquinoline alkaloid biosynthesis, indole alkaloid biosynthesis and tropane, piperidine and pyridine alkaloid biosynthesis) and a considerable number of genes such as AED3-like, A4U43, 21 kDa protein-like, 3-O-glycotransferase 2-like, AtDIR19, MST4, CASP-like protein 1D1 were discovered in association with the biosynthesis of alkaloids in leaves and roots. Some transcription factor families, i.e., AP2/ERF, GRAS, NAC, bHLH, MYB-related, C3H, FARI, WRKY, HB-HD-ZIP, C2H2, and bZIP were also found to have a prominent role in regulating the synthesis of alkaloids and steroidal alkaloids in the leaves and roots of V. mengtzeanum. The metabolome analysis revealed 74 significantly accumulated metabolites, with 55 differentially accumulated in leaves compared to root tissues. Out of 74 metabolites, 18 alkaloids were highly accumulated in the roots. A novel alkaloid compound viz; 3-Vanilloylygadenine was discovered in root samples. Conjoint analysis of transcriptome and metabolome studies has also highlighted potential genes involved in regulation and transport of alkaloid compounds. Here, we have presented a comprehensive metabolic and transcriptome profiling of V. mengtzeanum tissues. In earlier reports, only the roots were reported as a rich source of alkaloid biosynthesis, but the current findings revealed both leaves and roots as significant manufacturing factories for alkaloid biosynthesis.

Abstract
Cadmium (Cd) is detrimental to animals, but nephrotoxic effects of Cd on duck have not been fully elucidated. To evaluate the impacts of Cd on Ca homeostasis and autophagy via PLC-IP3 -IP3 R pathway, primary duck renal tubular epithelial cells were exposed to 2.5 μM and 5.0 μM Cd, and combination of 5.0 μM Cd and 10.0 μM 2-APB or 0.125 μM U-73122 for 12 h (U-73122 pretreated for 1 h). These results evidenced that Cd induced [Ca2+ ]c overload mainly came from intracellular Ca store. Cd caused [Ca2+ ]mit and [Ca2+ ]c overload with [Ca2+ ]ER decrease, elevated Ca homeostasis related factors (GRP78, GRP94, CRT, CaN, CaMKII, and CaMKKβ) expression, PLC and IP3 activities and IP3 R expression, but subcellular Ca2+ redistribution was reversed by 2-APB. PLC inhibitor U-73122 dramatically relieved the changes of the above indicators induced by Cd. Additionally, U-73122 obviously reduced the number of autophagosomes and LC3 accumulation spots, Atg5, LC3A, LC3B mRNA levels and LC3II/LC3I, Beclin-1 protein levels induced by Cd, and markedly elevated p62 mRNA and protein levels. Overall, the results verified that Cd induced [Ca2+ ]c overload mainly originated from ER Ca2+ release mediated by PLC-IP3 -IP3 R pathway, then triggered autophagy in duck renal tubular epithelial cells.

Veratrum parviflorum: An Underexplored Source for Bioactive Steroidal Alkaloids. Molecules 2022; 27:molecules27165349.

Abstract
Plants of the Veratrum genus have been used throughout history for their emetic properties, rheumatism, and for the treatment of high blood pressure. However, inadvertent consumption of these plants, which resemble wild ramps, induces life-threatening side effects attributable to an abundance of steroidal alkaloids. Several of the steroidal alkaloids from Veratrum spp. have been investigated for their ability to antagonize the Hedgehog (Hh) signaling pathway, a key pathway for embryonic development and cell proliferation. Uncontrolled activation of this pathway is linked to the development of various cancers; most notably, basal cell carcinoma and acute myeloid leukemia. Additional investigation of Veratrum spp. may lead to the identification of novel alkaloids with the potential to serve as chemotherapeutics. V. parviflorum is a relatively uncommon species of Veratrum that resides in the southeastern regions of North America. The phytochemical profile of this plant remains largely unexplored; however, bioactive steroidal alkaloids, including cyclopamine, veratramine, veratridine, and verazine were identified in its extract. The structural elucidation and bioactivity assessment of steroidal alkaloids in lesser abundance within the extract of V. parviflorum may yield potent Hh pathway inhibitors. This review seeks to consolidate the botanical and phytochemical information regarding V. parviflorum.

Abstract
Newcastle disease virus (NDV)-mediated gene therapy is a promising new approach for treatment of cancer but shows limited anti-angiogenesis. VEGF-Trap plays a vital role in anti-angiogenesis. To enhance the anti-tumor effect of NDV, VEGF-Trap gene was incorporated into the genome of rNDV in this study (named rNDV-VEGF-Trap). Results showed that rNDV-VEGF-Trap reduced cell growth ratio by 85.37% and migration ratio by 87.9% in EA.hy926 cells. In vivo studies, rNDV-VEGF-Trap reduced tumor volume and weight of CT26-bearing mice by more than 3 folds. Immunohistochemistry analysis of CD34 showed rNDV-VEGF-Trap significantly decreased the number of vascular endothelial cells in the tumor tissues. Moreover, Western blot analysis demonstrated that treatment with rNDV-VEGF-Trap significantly decreased the phosphorylation levels of AKT, ERK1/2 and STAT3 and increased the expression levels of P53, BAX and cleaved caspase-3 in the tumor tissue. In addition, to evaluate the toxicity of rNDV-VEGF-Trap, serum chemistries were analyzed. The results showed that rNDV-VEGF-Trap caused insignificant changes of creatinine levels, alanine aminotransferase and aspartate transaminase. Furthermore, administration of rNDV-VEGF-Trap did not cause the diarrhoea, decreased appetite, weight decrease and haemorrhage of the experimental mice. These data suggest that rNDV-VEGF-Trap exhibits an enhanced inhibition of CT26-bearing mice by enhancing anti-angiogenesis and apoptosis and may be a potential candidate for carcinoma therapy especially for colon cancer.

Anticancer effects of veratramine via the phosphatidylinositol-3-kinase/serine-threonine kinase/mechanistic target of rapamycin and its downstream signaling pathways in human glioblastoma cell lines. Life Sci 2022; 288:120170. [PMID: 34826438 DOI: 10.1016/j.lfs.2021.120170] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 11/10/2021] [Accepted: 11/18/2021] [Indexed: 02/06/2023]
Abstract
AIMS Antitumor effects of veratramine in prostate and liver cancers has been investigated, but it is still unclear whether veratramine can be used as an effective therapeutic agent for glioma. The aim of this study was to evaluate the potential pharmacological mechanism of veratramine in glioma. MAIN METHODS Using four types of human glioblastoma cell lines, including A172, HS-683, T98G, and U-373-MG the dose-dependent antitumor effect of veratramine was evaluated. The cytotoxicity and cell proliferation were examined by CCK-8, and cell proliferation was further confirmed by anchorage-independent colony formation assay. The cell cycle distribution and apoptotic rate was assessed by flow cytometry, and apoptosis was further evaluated by apoptosis assay. The migration and invasiveness capacity were analyzed by using transwell. Protein and mRNA levels of related factors were determined by western blotting and RT-qPCR, respectively. KEY FINDINGS Veratramine markedly induced apoptosis, suppressed the cell proliferation via the cell cycle G0/G1 phase arrest, and reduced the capacity for the migration and invasion in human glioblastoma multiforme cell lines. Moreover, veratramine was sufficient to affect the phosphatidylinositol-3-kinase/serine-threonine kinase/mechanistic target of rapamycin signaling pathway and its downstream Mdm2/p53/p21 pathway in human glioblastoma cell lines. SIGNIFICANCE Antitumor effects of veratramine in suppression of glioma progression was mediated by the regulation of PI3K/Akt/mTOR and Mdm2/p53/p21 signaling pathway.

Kunxianqi contains numerous compounds with demonstrated activity against breast cancer (BRCA). However, it is unknown whether 3-epipachysamine B also has anti-BRCA efficacy. In the present study, we employed network pharmacology technology to search and find potential molecular targets of 3-epipachysamine B. We applied cell proliferation, apoptosis, and western blotting assays to test the predicted key targets and the effects of 3-epipachysamine B against BRCA. Network pharmacology disclosed 80 potential BRCA-related targets of 3-epipachysamine B and assigned them to 75 signaling pathways. Of these, the most highly enriched was the PI3K/AKT signaling pathway. PIK3R1, AKT1, and mTOR had high degrees and betweenness centrality in protein-protein interaction network and are associated with PI3K/AKT signaling. Molecular docking and molecular dynamics simulation indicated strong binding between 3-epipachysamine B and PIK3R1, AKT1, and mTOR. 3-Epipachysamine B repressed the proliferation and induced the apoptosis of BRCA cells, as well as downregulated P-AKT/AKT, P-mTOR/mTOR, and P-PI3K/PI3K in the cells. The PI3K inhibitor LY294002 augmented these changes. Hence, 3-epipachysamine could also prove effective as an anticancer agent in future animal tumor model and human clinical breast cancer trials. Successful validation results could lead to a safe and effective new breast cancer treatment that improves patient prognosis and quality of life.

Downregulation of HBx Restrains Proliferation, Migration, and Invasion of HepG2 Cells. ACTA ACUST UNITED AC 2021; 2021:6615979. [PMID: 34094815 PMCID: PMC8140855 DOI: 10.1155/2021/6615979] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2020] [Revised: 04/20/2021] [Accepted: 05/03/2021] [Indexed: 12/30/2022]
Abstract
Liver cancer is a major contributor to cancer-related death with poor survival for sufferers. Meanwhile, Hepatic B virus X protein (HBx) and XB130 are likely to participate in the pathogenesis of liver cancer. However, the detailed mechanism of HBx/XB130 in liver cancer remains to be further investigated. Our study explored the effects of HBx/XB130 on liver cancer progression. HBx and XB130 expression was detected by reverse transcription quantitative polymerase chain reaction (RT-qPCR) and Western blot. Overexpression of HBx and XB130 was found in liver cancer tissues and cells. Mechanistic study revealed that HBx could bind to and positively regulate XB130 in HepG2 cells. Subsequently, HBx expression was knocked down, while XB130 was overexpressed in HepG2 cells in order to observe the specific role of HBx/XB130 in liver cancer in vitro. Results of CCK-8, Transwell, wound healing, and colony formation assays suggested that HBx could mediate biological function of HepG2 cells by activating the XB130-mediated PI3K/AKT pathway. In summary, our data illustrate that inhibition of HBx effectively suppressed proliferation and metastasis and induced apoptosis of liver cancer cells, which might be partially reversed by XB130. HBx and XB130 may be potential targets for liver cancer pathogenesis.
