Quercetin 7-rhamnoside from Sorbaria sorbifolia exerts anti-hepatocellular carcinoma effect via DHRS13/apoptotic pathway

BackgroundPrevious research demonstrated the effects of Sorbaria sorbifolia (SS) in combating hepatocellular carcinoma (HCC). Despite SS's proven efficacy in treating HCC, the precise bioactive constituents contributing to its therapeutic benefits, along with the mechanisms behind them, warrant further exploration. PurposeThe objective of our study was to illuminate the possible elements, targets, and modulatory pathways employed by specific bioactive components in SS for HCC treatment. Study designUsing UPLC-Q-TOF-MS to analyze and quantify the bioactive constituents in the SS sample. By literature review, we gathered potential chemical constituents of SS. We used network pharmacology approaches to identify HCC-related targets of SS components, with an emphasis on core targets. To examine the core targets' importance in HCC biological processes, bioinformatics methods were utilized. Finally, molecular docking, MD simulations, and CESTA were employed to screen SS active ingredients capable of stably binding with core targets. To verify the anti-HCC effectiveness of these active components, we conducted several cellular experiments, including CCK8, wound healing, transwell, cell cycle, and apoptosis assays, as well as animal experiments like zebrafish HepG2 cell xenotransplantation, apoptosis assays, and HE staining. We also used lentivirus transfection to modulate core protein expression in HepG2 cells, creating cell models. Further cellular tests were performed to evaluate the ability of SS active ingredients to exert anti-HCC effects by interacting with the core protein to induce apoptosis. Finally, Western Blot and ELISA experiments were carried out to track changes in core protein and apoptosis-related pathway proteins after SS active ingredient treatment ResultsOur study identified 50 components in SS and 119 HCC-related target genes, with DHRS13 emerging as a core target. Further bioinformatics analysis indicated that DHRS13 expression in HCC patients correlated with prognosis and apoptotic pathways. Molecular docking revealed 20 active SS constituents effectively binding to DHRS13, MD simulations and CESTA pinpointed Quercetin 7-rhamnoside (Q7R) as the most stable binder. In-vitro and in-vivo tests verified Q7R's anti-HCC properties. Lentivirus transfection results showed that knockdown DHRS13 led to reduced cell growth and increased apoptosis, while overexpression DHRS13 led to increase cell growth and decrease apoptosis. Remarkably, our experiments found that Q7R acts as an inhibitor of DHRS13 and can reverse the suppressed apoptosis and excessive HCC proliferation caused by DHRS13 overexpression. ConclusionElevated DHRS13 expression contributes to HCC progression. Q7R effectively downregulates DHRS13, encouraging apoptosis and impeding HCC growth. As a result, Q7R shows potential as a therapeutic agent for HCC treatment, targeting the apoptotic pathway through DHRS13 regulation.

Mechanisms of action of Sappan lignum for prostate cancer treatment: network pharmacology, molecular docking and experimental validation.

Prostate cancer (PCa) is the most common non-cutaneous malignancy in men globally. Sappan lignum, which exists in the heartwood of Caesalpinia sappan L., has antitumor effects; however, its exact mechanism of action remains unclear. This study elucidated the underlying mechanisms of Sappan lignum in PCa through network pharmacology approaches and molecular docking techniques. Moreover, the therapeutic effects of Sappan lignum on PCa were verified through in vitro experiments. The constituent ingredients of Sappan lignum were retrieved from the HERB database. Active plant-derived compounds of Sappan lignum were screened based on gastrointestinal absorption and gastric drug properties. Disease targets for PCa were screened using unpaired and paired case datasets from the Gene Expression Omnibus. Intersection targets were used for gene ontology and Kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment analysis. Core targets were identified through topological analysis parameters and their clinical relevance was validated through The Cancer Genome Atlas database. The affinity between the phytochemicals of Sappan lignum and core proteins was verified using the molecular docking technique. Validation experiments confirmed the significant potential of Sappan lignum in treating PCa. Twenty-one plant-derived compounds of Sappan lignum and 821 differentially expressed genes associated with PCa were collected. Among 32 intersection targets, 8 were screened according to topological parameters. KEGG analysis indicated that the antitumor effects of Sappan lignum on PCa were primarily associated with the p53 pathway. The molecular docking technique demonstrated a strong affinity between 3-deoxysappanchalcone (3-DSC) and core proteins, particularly cyclin B1 (CCNB1). CCNB1 expression correlated with clinicopathological features in patients with PCa. Experimental results revealed that 3-DSC exhibited anti-proliferative, anti-migratory, and pro-apoptotic effects on 22RV1 and DU145 cells while also causing G2/M phase cell cycle arrest, potentially through modulating the p53/p21/CDC2/CCNB1 pathway. This research highlights the promising therapeutic potential of Sappan lignum in treating PCa, with a particular focus on targeting the p53 pathway.

Anti-ageing mechanism of topical bioactive ingredient composition on skin based on network pharmacology.

To elucidate the anti-ageing mechanism of the combination of eight ingredients on the skin from a multidimensional view of the skin. The target pathway mechanisms of composition to delay skin ageing were investigated by a network pharmacology approach and experimentally validated at three levels: epidermal, dermal, and tissue. We identified 24 statistically significant skin ageing-related pathways, encompassing crucial processes such as epidermal barrier repair, dermal collagen and elastin production, inhibition of reactive oxygen species (ROS), as well as modulation of acetylcholine and acetylcholine receptor binding. Furthermore, our invitro experimental findings exhibited the following outcomes: the composition promotes fibroblast proliferation and the expression of barrier-related genes in the epidermis; it also stimulated the expression of collagen I, collagen III, and elastic fibre while inhibiting ROS and β-Gal levels in HDF cells within the dermis. Additionally, Spilanthol in the Acmella oleracea extract contained in the composition demonstrated neuro-relaxing activity in Zebrafish embryo, suggesting its potential as an anti-wrinkle ingredient at the hypodermis level. In vitro experiments validated the anti-ageing mechanism of composition at multiple skin levels. This framework can be extended to unravel the functional mechanisms of other clinically validated compositions, including traditional folk recipes utilized in cosmeceuticals.

A cheminformatics and network pharmacology approach to elucidate the mechanism of action of Mycobacterium tuberculosis γ-carbonic anhydrase inhibitors.

Mycobacterium tuberculosis (Mtb) carbonic anhydrases (CAs) are critical enzymes that regulate pH by converting CO2 to HCO3 -, essential for Mtb's survival in acidic environments. Inhibiting γ-CAs presents a potential target for novel antituberculosis drugs with unique mechanisms of action. This study aimed to explore the biological connections underlying Mtb pathogenesis and investigate the mechanistic actions of antituberculosis compounds targeting the Cas9 protein. We employed homology modeling and virtual screening to identify compounds with high binding affinities for Cas9 protein. This study used the homology modeling approach employing high-quality AlphaFold DB models for γ-CA. Furthermore, the systems biology approach was used for analyzing the integrated modelling of compounds, integrating data on genes, pathways, phenotypes, and molecular descriptors. Single-cell RNA sequencing was also conducted to profile gene expression. Three compounds, F10921405, F08060425, and F14437079, potentially binding to Cas9 protein, have been identified. F10921405 and F08060425 showed significant overlap in their effects on pathways related to the immune response, while F14437079 displayed distinct mechanistic pathways. Expression profiling revealed high levels of genes such as PDE4D, ROCK2, ITK, MAPK10, and SYK in response to F1092-1405 and F0806-0425, and MMP2 and CALCRL in response to F1443-7079. These genes, which play a role in immune modulation and lung tissue integrity, are essential to fight against Mtb. The molecular relationship and pathways linked to the mentioned compounds give the study a holistic perspective of targeting Mtb, which is essential in designing specific therapeutic approaches. Subsequent research will involve experimental validation to demonstrate the efficacy of the promising candidates in Mtb infections.

Analysis of the mechanism of berberine against stomach carcinoma based on network pharmacology and experimental validation.

Although the therapeutic effects of berberine have received some attention in recent years, its potential mechanisms underlying its action against stomach carcinoma (SC) remain unclear. In this study, we aimed to elucidate the mechanisms underlying the effects of berberine against SC using a network pharmacology and experimental verification approach. Several publicly available databases were used to collect the targets of berberine and SC. Protein-protein interaction (PPI) network, enrichment analyses and molecular docking were performed based on the potential targets of berberine against SC. The potential clinical significance and prognostic value of the targets were predicted by using nomogram and receiver operating characteristic (ROC) analyses. Then the viability and apoptosis of SC cells treated with berberine were determined. Moreover, reactive oxygen species (ROS), mitochondrial membrane potential (MMP) and adenosine triphosphate (ATP) measurements and western blot assay were carried out to validate the predicted mechanisms. Seventy-six potential targets of berberine against SC were identified. The construction of PPI network enabled the identification of hub targets, such as AKT1, TP53, IL6, JUN and MAPK1. Enrichment analyses showed that berberine was involved in apoptosis, mitophagy, ROS metabolic process, AMPK and MAPK signaling pathway. The expression levels of hub targets also contributed to the clinical prognosis of patients with SC. Molecular docking revealed the possible patterns of direct interaction between berberine and target proteins, including AMPK, TP53 and MAPK1. Experimental results showed that berberine reduced SC cell viability, promoted apoptosis and ROS generation, and contributed to reductions in MMP and ATP levels. Western blot assay demonstrated that berberine increased AMPK and TP53 expression, while decreased phosphorylated-MAPK3/1 expression. We elucidated the potential action mechanisms of berberine against SC using a network pharmacology approach. Some predicted mechanisms underlying the anti-SC effects were verified based on experimental approaches. Our findings provide a meaningful foundation for berberine as a cellular apoptosis-inducing and energy metabolism-regulating agent against SC. However, in vivo experiments and clinical studies need to be further carried out. Moreover, it is necessary to study the potential negative effects of berberine thoroughly.

Network pharmacology, molecular docking and experimental approaches of the anti-proliferative effects of Rhamnus prinoides ethyl-acetate extract in cervical cancer cells

BackgroundCervical cancer, one of the lethal cancers among women, is a challenging disease to treat. The current therapies often come with severe side effects and the risk of resistance development. Traditional herbal medicine, with its potential to offer effective and less toxic options, is a promising avenue. This study was undertaken to investigate the potential of Rhamnus prinoides (R. prinoides) root bark extracts in selectively inhibiting the proliferation of cervical cancer cells, using the HeLa cell line as an in vitro model. MethodsR. prinoides plant extracts were first screened at a fixed concentration of 200 μg/ml to determine the active extract. The selective anti-proliferative activity of the active extract was evaluated in a concentration dilution assay using the (3-(4,5-dimethylthiazol- 2-yl)-2,5-diphenyltetrazolium bromide) MTT assay on cancerous (HeLa) cells and non-cancerous (Vero) cells to determine the half-maximal inhibitory (IC50) and half-cytotoxic concentrations (CC50), respectively. Functional assays on cell morphology (by microscopy), cell migration (wound healing assay) and cell cycle (by flow cytometry) were also conducted. The active extract was analyzed using Gas Chromatography/Mass Spectrometry (GC/MS) to determine any compounds it contained. Following identification of possible gene targets by network pharmacology, the genes were validated by molecular docking and Real-Time Quantitative Polymerase Chain Reaction (RT-qPCR). ResultsThe ethyl acetate extract of R. prinoides (EARP), the most active extract, selectively inhibited the growth of cervical cancer cells, their migration and induced cell cycle arrest at the S phase. In silico analysis revealed that squalene, 3,3a,6,6-tetramethyl-4,5,5a,7,8,9-hexahydro-1H-cyclopenta[i]indene and Olean-12-en-3.beta.-ol, acetate showed acceptable drug-like characteristics and may be partly attributed to the bioactivity demonstrated and the deregulation of the mRNA expression of AKT1, NF-κB, p53, Bax, Bcl-2, and Er-b-B2. ConclusionThis study, for the first time, demonstrates the anti-proliferation effects of EARP and forms a firm foundation for further drug development studies.

Carbonic anhydrase 2 mediates anti-obesity effects of black tea as thermogenic activator

Obesity is a metabolic disorder due to over-accumulation of adipose tissue and ultimately becomes a “disease”. Brown adipose tissue (BAT) thermogenesis and white adipose tissue (WAT) browning emerge as a potential strategy of anti-obesity by dissipating energy as heat. However, drugs based on adipose tissue thermogenesis have not been successfully approved yet. In current study, we found that black tea extract (BTE) obtained by patent-authorized manufacturing process prevented body weight gain as novel thermogenic activator with reduction of adiposity, improvement of adipose distribution, and glucose metabolism improvement in diet-induced obesity mice. Mechanismly, anti-obesity effect of BTE depends on promoting BAT thermogenesis and WAT browning with upregulation of uncoupling protein 1 (UCP1), especially visceral adipose tissue (VAT) with browning resistance. Specifically, utilizing in silico approach of network pharmacology and molecular docking, we identified carbonic anhydrase 2 (CA2) in nitrogen metabolism as anti-obesity target of BTE and further elucidated that protein kinase B (AKT) signaling pathway linked CA2 and UCP1. Meanwhile gut microbiota regulation may prompt the CA2-dependent thermogenesis activation. Our findings demonstrated anti-obesity effect of BTE as thermogenic activator through CA2-mediated BAT thermogenesis and WAT browning via CA2-AKT-UCP1 signaling pathway, which could be developed as promising anti-obesity agent with good safety and efficacy.

Farrerol alleviates insulin resistance and hepatic steatosis of metabolic associated fatty liver disease by targeting PTPN1.

Metabolic associated fatty liver disease (MAFLD) is the most common chronic liver disease worldwide, characterized by excess lipid deposition. Insulin resistance (IR) serves as a fundamental pathogenic factor in MAFLD. However, currently, there are no approved specific agents for its treatment. Farrerol, a novel compound with antioxidant and anti-inflammatory effects, has garnered significant attention in recent years due to its hepatoprotective properties. Despite this, the precise underlying mechanisms of action remain unclear. In this study, a network pharmacology approach predicted protein tyrosine phosphatase non-receptor type 1 (PTPN1) as a potential target for farrerol's action in the liver. Subsequently, the administration of farrerol improved insulin sensitivity and glucose tolerance in MAFLD mice. Furthermore, farrerol alleviated lipid accumulation by binding to PTPN1 and reducing the dephosphorylation of the insulin receptor (INSR) in HepG2 cells and MAFLD mice. Thus, the phosphoinositide 3-kinase/serine/threonine-protein kinases (PI3K/AKT) signalling pathway was active, leading to downstream protein reduction. Overall, the study demonstrates that farrerol alleviates insulin resistance and hepatic steatosis of MAFLD by targeting PTPN1.

ResultAltogether, 78 DGBXD active compounds and 223 DGBXD-related, 146 component-disease common, and 2168 GIOP-associated target genes were obtained. The PPI network had 43 nodes and 462 edges, and a total of 10 core target genes, including TP53, JUN and MAPK3, were identified. The results of the GO enrichment analysis implied that DGBXD might participate in biological activities, including responses to oxidative stress and nutrient levels. The outcomes of the KEGG pathway enrichment analysis showed that DGBXD may treat GIOP through TNF, IL-17, and phosphatidylinositol 3-kinase (PI3K)-Akt signaling pathways. Based on to the molecular docking results, biologically active compounds (beta-carotene, formononetin, luteolin, and isorhamnetin) exhibited good binding to AKT1 and ESR1. ConclusionDGBXD may aid in GIOP treatment by modulating multiple therapeutic targets and signaling pathways.
