Tetrastigma hemsleyanum Diels et Gilg, a plant of the Vitaceae family, is often used as a medicine. Modern pharmacological studies have found that its root tubers have a particular anticancer effect. Polydatin, piceatannol, resveratrol, and kaempferol could be detected stably in this herbal plant, which are vital indicators for controlling and evaluating its quality. At present, its planting mode is chaotic and complicated. In order to explore the optimal cultivation mode with excellent quality and yield, the agronomic indicators, the indicators of conventional medical materials and the content of active ingredients were determined in this study. Then, their discrepancy under different planting bases and various planting modes was analyzed. The T. hemsleyanum cultivated in the greenhouse had the thickest stems and the longest leaves, as well as the largest aerial and underground biomass. Compared with understory planting, the root tubers have higher total flavonoid content in the greenhouse planting mode. In addition, the index component content of the stereoscopic planting was higher than that of the crawl planting. In summary, greenhouse planting combined with stereoscopic planting mode was conducive to improving the yield and quality of T. hemsleyanum simultaneously. These results provided a more comprehensive reference basis for the artificial planting of T. hemsleyanum . Simultaneously, it provided a theoretical basis for strengthening the sustainable development and utilization of medicinal materials from T. hemsleyanum and protection of resources.

Tetrastigma hemsleyanum Diels et Gilg, a rare herbal plant native to China, possesses high medicinal value. More researches have focused on the flavones in the tubers of Tetrastigma hemsleyanum whereas polysaccharides attract few attentions. In this study, a purified polysaccharide (TTP-1) with the average molecular weights of 478.33 kDa was extracted from Tetrastigma hemsleyanum and conducted multiple analysis to identify its structural information. In vitro , TTP-1 could suppress the inflammation, cytotoxicity, genotoxicity, mitochondrial dysfunction and oxidative damage induced by LPS in RAW264.7 cells. Meanwhile, TTP-1 could attenuate inflammation via COX-2, iNOS, MAPKs pathways and ameliorate oxidative damage through Nrf2-Keap1, Sirt1-FoxO1 pathways in RAW264.7 cells. In vivo , the inflammation induced by LPS triggered the suppression of survival ratio and growing development, as well as the restrain of athletic ability in Caenorhabditis elegans . The treatment of TTP-1 reversed the situation induced by LPS. In a word, TTP-1 could ameliorate LPS-induced inflammation both in vitro and in vivo .

A novel acidic glucuronogalactomannan (STHP-5) was isolated from the aboveground part of Tetrastigma hemsleyanum Diels et Gilg with a molecular weight of 3.225 × 10 5 kDa. Analysis of chain conformation showed STHP-5 was approximately a random coil chain. STHP-5 was composed mainly of galactose, mannose, and glucuronic acid. Linkages of glycosides were measured via methylation analysis and verified by NMR. Based on the structural characterization, the repeat unit of STHP-5 was proposed. In vitro, STHP-5 induced the production of nitric oxide (NO) and secretion of IL-6, MCP-1, and TNF-α in RAW264.7 cells, indicating STHP-5 had stimulatory activity on macrophages. STHP-5 was proven to function as a TLR4 agonist by inducing the secretion of secreted embryonic alkaline phosphatase (SEAP) in HEK-Blue™-hTLR4 cells. The TLR4 activation capacity was quantitatively measured via EC50, and it showed purified polysaccharides had stronger effects (lower EC50) on activating TLR4 compared with crude polysaccharides. In conclusion, our findings suggest STHP-5 may be a novel immunomodulator.

Acrylamide (ACR), as a raw material of polyacrylamide that used in water purification, was verified to possess various toxicity. Tetrastigma hemsleyanum (TH) is a medicinal plant widely used to anti-inflammation and anti-tumor in Chinese folks. However, more researches focused on the biological activities in tubers and the leaves were ignored. Thus, the protective effect of Tetrastigma hemsleyanum leaves extract (THLE) against ACR-induced toxicity in HepG2 cells and Caenorhabditis elegans ( C. elegans ) was explored in this study. In vitro , we observed that THLE attenuated ACR-induced toxicity in HepG2 cell via regulating Akt/mTOR/FOXO1/MAPK signaling pathway. Further research proved that 5-caffeoylquinic acid (5-CA) plays a major role in THLE’s amelioration effect of ACR toxicity. In vivo , it was found that THLE possesses the same protective effect in ACR-treated wild-type N2 C. elegans and daf-2 (-) (deficit in DAF-2) mutants. However, the anti-ACR toxicity effect of THLE in daf-16 (-) mutants (deficit in DAF-16 that homologous to FOXO family in human) was weakened. Our results indicated that THLE exhibited protective effects against ACR-induced toxicity both in HepG2 cells and C. elegans , while DAF-16/FOXO gene is involved in THLE’ protective effect via regulating the expression levels of downstream antioxidant genes.

Background Thrombosis, driven by abnormal platelet activation and fibrin clot formation, is a key pathological basis of cardiovascular disorders. Polysaccharide-based agents, such as heparin, possess distinct antithrombotic activities. Tetrastigma hemsleyanum polysaccharide (THP) exhibits notable anti-inflammatory properties. However, its antithrombotic potential remains unexplored. Purpose This work intended to explore the antithrombotic and antiplatelet activities of THP5, a novel acidic glucuronic acid-containing galactomannan isolated from THP, and to elucidate its molecular targets and mechanisms of platelet interaction. Methods The antithrombotic activity of THP5 was tested in vivo using a mouse model of κ-carrageenan-induced thrombosis. In vitro platelet function assays determined its antiplatelet effects. Platelet protein targets were identified via pull-down, liquid chromatography-mass spectrometry (LC-MS/MS), and surface plasmon resonance (SPR) analyses. Comparative studies with the GPIIb/IIIa inhibitor tirofiban were performed in κ-carrageenan- and FeCl 3 -induced thrombosis models. Proteomic profiling and bleeding risk assessments were conducted to investigate underlying mechanisms and safety. Results THP5 markedly reduced thrombus formation, attenuated inflammatory responses, and alleviated vascular injury in vivo. In vitro , it protected endothelial cells from LPS-induced damage and strongly inhibited platelet activation. GPIIb/IIIa was identified as a direct binding target of THP5, and proteomic analysis revealed modulation of the MAPK signaling pathway. Compared with tirofiban, THP5 demonstrated comparable efficacy with a lower bleeding risk. Conclusion THP5 exerts potent antithrombotic effects by directly targeting GPIIb/IIIa and modulating PKCα-MAPK-dependent platelet activation, supporting its potential as a safe and effective therapeutic candidate for thrombotic disorders.

Tetrastigma hemsleyanum is a perennial evergreen vine of the Vitaceae. The entire herb is used in traditional Chinese medicine as a broad-spectrum plant-based antibiotic, so it has high economic and social value. Wild T. hemsleyanum resources are scarce, so it has been declared an endangered and rare medicinal plant. Seed yield is low and vegetative propagation by cuttings results in limited plant production, so development of the T. hemsleyanum industry requires optimized propagation protocols and the development of new biotechnologies to proliferate this plant in commercial quantities. In this study, shoot organogenesis was successfully induced from leaves and petioles. Two plant growth regulators, 6-benzyladenine (BA) and thidiazuron, induced callus and adventitious shoots, but the ideal adventitious shoot induction medium was Murashige and Skoog (MS) medium containing 1.0 mg L −1 BA and 0.1 mg L −1 α-naphthaleneacetic acid (NAA). This resulted in a shoot proliferation coefficient (SPC) of 6.73 within 30 d at a light intensity of 100 µmol m −2 s −1 . When light intensity was increased from 50 to 200 µmol m −2 s −1 , SPC (7.35), chlorophyll a (Chl a ), Chl b , and total Chl ( a + b ) content increased. On MS medium containing 0.1–2.0 mg L −1 NAA or indole-3-butyric acid, 100% of adventitious shoots formed adventitious roots. Plantlets showed no obvious morphological variation, and their survival exceeded 98% on a substrate of peat and river sand ( v:v = 2:1). This study’s protocols allow for the mass production of adventitious shoots for conservation purposes, and potentially for the commercial propagation of T. hemsleyanum .

As the market of Tetrastigma hemsleyanum Diels et Gilg (TH) products rapidly expands and consumer demand increases, identifying the chemical components and evaluating its safety can help ensure human health during their usage. In this study, GC-MS and LC-MS were used to investigate the phytochemical characteristics of the TH leaf extracts, and the safety of TH extracts was evaluated using zebrafish embryos and larvae, with specific endpoints including the hatching rate, mortality rate, and the overall morphology. It revealed that TH leaves were rich in vitamins, flavonoids, terpenoids, etc. A total of 31 and 42 metabolites was identified in the n-hexane extract and the 60 % methanol aqueous extract of TH leaves, respectively, using GC-MS and LC/Q-TOF-MS techniques. DL-alpha-tocopherol was discovered for the first time in TH leaves. Seven exposure levels (0.02–6.4 mg/mL) of the aqueous extracts were employed in safety evaluation using zebrafish embryos. Our results indicated that the highest concentration (6.4 mg/mL) led to the lowest hatching rate (1.3 ± 1.8 %, P < 0.001) and the highest cumulative mortality rate (22.5 ± 9.4 %, P < 0.001). Subsequently, five exposure levels (0.02–1.6 mg/mL) were employed to evaluate the safety using zebrafish larvae. The results indicated that the treatment had no significant impact on the mortality rate, overall morphology, or specific organs (heart, liver, kidneys) of zebrafish larvae, nor did it induce morphological abnormalities. However, a concentration-dependent increase in heart rate was observed. This study provides a reference for consumers to use TH leaf safely and rationally.

With high morbidity and mortality, non-small cell lung cancer (NSCLC) has become a challenge for humans, because its clinic chemotherapies still remain unsatisfactory. In this study, the leaf part of a traditional Chinese plant, Tetrastigma hemsleyanum (TL), was studied, and its main flavones compounds were extracted and purified (TLF), which were composed of 5-caffeoylquinic acid, 3-caffeoylquinic acid, 4-caffeoylquinic acid, quercetin-3-O-rutinoside and kaempferol-3-O-rutinoside. To study the anti-NSCLC ability of TLF, in vitro and in vivo studies were done. TLF inhibited the proliferation and migration of A549 cells and caused mitochondrial dysfunction. TLF significantly suppressed the tumor weight and volume, and down-regulated Ki67, proliferation cell nuclear antigen (PCNA) and vascular endothelial growth factor (VEGF) productions. To determine the intrinsic mechanism, proteins alternations were measured in solid tumors, and results showed that TLF blocked the Akt/mTOR pathway, and thereby induced autophagy, triggering Bcl and Caspase-dependent pathways, resulting in A549 cells’ apoptosis. This study indicated that TLF is a potential candidate to be an anti-NSCLC drug, or a supplementary resource for chemotherapy.

Background Luminescent nanomaterials (LNMs), especially newly-exploited fluorescent carbon-dots (CDs), have demonstrated promising candidates for sunlight harvesting and enhanced photosynthesis efficiency of crops. However, most of the studies focus on the design and synthesis of LNMs and primary metabolism in biomass acceleration, secondary metabolism that closely associated with the quality ingredients of plants is rarely mentioned. Results UV-absorptive and water-soluble NIR-CDs were harvested via a facile microwave-assisted carbonization method. The effect and regulatory mechanism of NIR-CDs on the secondary metabolism and bioactive ingredients accumulation in Tetrastigma hemsleyanum were explored. A total of 191 differential secondary metabolites and 6874 differentially expressed genes were identified when the NIR-CDs were adopted for enhancing growth of T. hemsleyanum . The phenolic acids were generally improved, but the flavonoids were more likely to decrease. The pivotal differentially expressed genes were involved in biosynthesis of secondary metabolites, flavonoid biosynthesis, porphyrin and chlorophyll metabolism, etc. The gene-metabolite association was constructed and 44 hub genes highly related to quality ingredients accumulation and growth were identified, among which and the top 5 genes of the PPI network might be the key regulators. Conclusion This research provided key regulatory genes and differentially accumulating quality ingredients under NIR-CDs-treatment, which could provide a theoretical basis for expanding the applications of nanomaterial in industrial crop agriculture.

Background Lung cancer is one of the malignant tumors with the highest mortality in the world. Quercetin (Qu) is a flavonoid compound isolated from Tetrastigma hemsleyanum Diels & Gilg (SYQ), which has multi-target anti-tumor activity. However, there are problems such as low extraction purity, poor water solubility, and difficulty in targeted delivery. Its anti-lung cancer mechanism remains to be elucidated. Objective To investigate the enrichment of Qu by molecularly imprinted polymers (MIPs) and to construct targeted micelles to improve its solubility, tumor targeting, and bioavailability and to explore its anti-lung cancer mechanism by in vitro cell experiments and in vivo animal models. Methods The static adsorption performance of Qu in SYQ extract was evaluated by MIPs. Key targets and pathways were predicted by network pharmacology and molecular docking. The targeted micelles were constructed, and their particle size, morphology, drug loading, and release behavior were characterized. The cytotoxicity and migration inhibition of free Qu and drug-loaded micelles on H1299 and A549 cells were evaluated by MTT assay, crystal violet staining, live/dead cell staining, and scratch healing assay. The uptake efficiency of Qu and the change of intracellular reactive oxygen species level were observed by confocal microscopy. The expression of the PI3K/AKT pathway protein was detected by Western blot, and the H1299 tumor-bearing mouse model was established to evaluate the in vivo distribution and anti-tumor effect. Results Qu was isolated and identified from SYQ extracts using ¹H NMR, MALDI-TOF, Q-TOF LC/MS, and FTIR. When the ratio of Qu to acrylamide was 1:7, the equilibrium adsorption capacity for Qu reached 393.26 μg/g. In network pharmacology, Qu and non-small cell lung cancer (NSCLC) shared 111 common target proteins, with a binding energy of -8.71 kcal/mol between Qu and the BCL-2. The HPP@Qu micelles exhibited a particle size of 107.75 nm, a drug loading capacity of 6.57%, and a cumulative release rate of 55.15% at 72 h. HPP@Qu significantly inhibited the viability and migration of H1299 cells, increased intracellular reactive oxygen species (ROS) levels, downregulated p-PI3K, p-AKT, and BCL-2 proteins, and upregulated cleaved caspase-3. Furthermore, HPP@Qu effectively accumulated in tumor tissues, suppressed tumor growth in tumor-bearing mice, and showed no obvious toxicity to major organs. Conclusion MIPs selectively enrich high-purity Qu from SYQ. Targeted micelles enhance Qu's solubility and tumor targeting, effectively inhibiting tumor growth. Qu induces H1299 cell apoptosis by elevating ROS levels, suppressing the PI3K/AKT pathway, downregulating BCL-2, and activating Caspase-3. These findings reflect the research value of Qu as a potential natural anticancer candidate drug.

Objective This study is mainly to elucidate the characteristic components, hepatoprotective effect, and the underlying anti-hepatic fibrosis molecular mechanism of the total flavonoids of Tetrastigma hemsleyanum Diels & Gilg (SYQTF). Methods The components of SYQTF were confirmed based on global natural products social molecular networking (GNPS) as well as the hepatoprotective effect on CCl 4 -induced acute liver injury. Cell toxicity and viability, cell cycle, and apoptosis analyses were then performed to determine the effects of SYQTF in transforming growth factor-β1 (TGF-β1) (10 ng/mL)-induced HSC-T6 hepatic fibrosis cell model. Finally, the lentiviral particles to package recombinant Ras-related C3 botulinum toxin substrate 1 (Rac1) over-expression and Rac1 knockdown plasmids were transfected into TGF-β1-induced HSC-T6 cells to elucidate the mechanism of anti-hepatic fibrosis of SYQTF targeting Rac1, respectively. Results Our findings demonstrated that 86 components in SYQTF were identified in MS E and FastDDA mode with the aid of GNPS. Moreover, S 15 -ZJ, the genuine functional food and medicinal materials of T. hemsleyanum , was significantly different from other regions by multivariate statistical methods based on progenesis QI. Remarkably, kaempferol-3- O -furananose7- O -rhamnosyl-glucoside, the highest response intensity in S 15 -ZJ, may act as the potential Q-marker of genuine functional food and medicinal materials of T. hemsleyanum in Zhejiang Province distinguished from other areas. In addition, the in vivo experiments revealed that SYQTF greatly alleviated CCl 4 -induced acute liver injury. Furthermore, SYQTF can reversible the activation and proliferation of HSC-T6 cells, block the cell cycle in the G 0 /G 1 phase, and promote cell apoptosis. Remarkably, the study is the first to reveal that SYQTF exhibited the anti-hepatic fibrosis effect through targeting Rac1 in the hedgehog signaling pathway. Conclusion Rac1 is an important signaling molecule for the activation of the hedgehog pathway in HSC-T6. Importantly, SYQTF exerted its anti-hepatic fibrosis effect by inhibiting the Rac1-hedgehog signaling pathway. Furthermore, kaempferol-3- O -furananose7- O -rhamnosyl-glucoside could be a potential Q-marker of T. hemsleyanum in Zhejiang Province distinguished from other areas.

Ethnopharmacological relevance Tetrastigma hemsleyanum （ T. hemsleyanum ）, valued in traditional medicine for its potential to boost immunity and combat tumors, contains uncharacterized active compounds and mechanisms. This represents a significant gap in our understanding of its ethnopharmacological relevance. Aim of the study To involve the mechanism of anti-lung cancer effect of T. hemsleyanum by means of experiment and bioinformatics analysis. Materials and methods The anticancer mechanism of T. hemsleyanum against lung squamous carcinoma (LUSC) in zebrafish was investigated. The LUSC model was established by injecting NCI–H2170 cells in the zebrafish and evaluating its anti-tumor efficacy. Next, component targets and key genes were obtained by molecular complex detection (MCODE) analysis and protein-protein interaction (PPI) network analysis. Component analysis of T. hemsleyanum was performed by UPLC-Q-TOF-MS. Molecular docking was used to simulate the binding activities of key potential active components to core targets were simulated using. Prognostic and pan-cancer analyses were then performed to validate the signaling pathways involved in the prognostic genes using gene set enrichment analysis (GSEA). Subsequently, Molecular dynamics simulations were then performed for key active components and core targets. Finally, cellular experiments were used to verify the expression of glutamate metabotropic receptor 3 (GRM3) and glutamate metabotropic receptor 7 (GRM7) in the anticancer effect exerted of T. hemsleyanum . Results We experimentally confirmed the inhibitory effect of T. hemsleyanum on LUSC by transplantation of NCI–H2170 cells into zebrafish. There are 20 main compounds in T. hemsleyanum , such as procyanidin B1, catechin , quercetin , and kaempferol , etc. A total of 186 component targets of T. hemsleyanum and sixteen hub genes were screened by PPI network and MCODE analyses. Molecular docking and molecular dynamics simulation results showed that Gingerglycolipid B and Rutin had higher affinity with GRM3 and GRM7 , respectively. Prognostic analysis, Pan-cancer analysis and verification experiment also confirmed that GRM3 and GRM7 were targets for T. hemsleyanum to exert anti-tumor effects and to participate in immune and mutation processes. In vitro experiments suggested that the inhibitory effect of T. hemsleyanum on cancer cells was correlated with GRM3 and GRM7. Conclusion In vivo, in vitro and in silico results confirmed the potential anticancer effects against LUSC of T. hemsleyanum , which further consolidated the claim of its traditional uses.
