Core Genes

Pien-Tze-Huang (PTH) has a long history in the treatment of liver cancer. However, its molecular mechanism of action remains unclear. TCMSP and TCM were used to collect the active ingredients. Bioactive compounds targets were predicted by reverse pharmacophore models. The antiliver cancer targets of PTH were selected by gene comparison of liver cancer in the GEO database. Molecular docking was used to verify the binding activity of the targets and the active ingredients. The DAVID was used to analyze the gene function and signal pathway. A model was built with Cytoscape. The core genes were obtained by PPI network. We screened the 4 main medicinal ingredients of PTH to obtain 16 active ingredient, 190 potential targets, and 6 core genes. We found that active small molecules exert anticancer effects by multiple pathways. The core genes were involved in multiple biological processes. We also found that eight chemical components play a greater role in inhibiting liver cancer. PTH achieves the effect of inhibiting liver cancer through the synergistic effect of multiple components, multiple targets, and multiple pathways. This study provides a potential scientific basis for further elucidating the molecular mechanism of action of PTH against liver cancer.

Cuscuta Chinensis

Abstract Background: Drynaria Fortunei and Cuscuta Chinensis are among the most used traditional Chinese medicine herbal prescriptions and have a significant therapeutic effect on osteoarthritis. However, the purpose of this study intends to elaborate the molecular mechanism of action through network pharmacology. The active ingredients of TCM and the potential targets for the treatment of osteoarthritis were selected through the TCMSP, OMIM and Genecards. Results: The 27 components and 85/117 targets of Drynaria Fortunei and/or Cuscuta Chinensis were identified for osteoarthritis. Pharmacological and PPI network analysis identified top 3 active components (kaempferol, luteolin, and quercetin) and core proteins (IL6, AKT1, and VEGFA). GO and KEGG analysis identified the top 3 functions (cytokine and cell/nuclear receptor) and pathways (PI3K-Akt, TNF and IL-17). Molecular docking showed strong binding ability between quercetin-AKT1 and luteolin-IL6/VEGFA. Interaction analysis mapped the quercetin-AKT1 and luteolin-IL6/VEGFA binding to specific hydrogen and hydrophobic bonds. Conclusions: The main active components, common target proteins, functional activities, and signaling pathways of TCM Drynaria Fortunei and Cuscuta Chinensis for the treatment of osteoarthritis were identified by Network pharmacology. We found, for the first time, that drynariae rhizoma and cuscuta chinensis suppress osteoarthritis by quercetin-AKT1/IL6 and luteolin-VEGFA direct binding. Our findings have significant implication for our understanding of the molecular mechanism of action in the treatment of osteoarthritis and future development of osteoarthritis treatment using quercetin and luteolin.

<div><div><div><p>GPX4 represents a promising yet difficult-to-drug therapeutic target for the treatment of, among others, drug-resistant cancers. While most GPX4 inhibitors rely on a chloroacetamide moiety to modify covalently the protein’s catalytic selenocysteine residue, the discovery and mechanistic elucidation of structurally diverse GPX4-inhibiting molecules has uncovered novel electrophilic warheads that bind and inhibit GPX4. Here we report our discovery that diacylfuroxans can act as masked nitrile oxides that inhibit GPX4 covalently. These observations illuminate a novel molecular mechanism of action for biologically active furoxans and also suggest that nitrile oxides may be uniquely suited to targeting GPX4.</p></div></div></div>

BACKGROUND: Shanmei Capsule is a famous preparation in China. However, the related mechanism of Shanmei Capsule against hyperlipidemia has yet to be revealed. OBJECTIVE: To elucidate underlying mechanism of Shanmei Capsule against hyperlipidemia through network pharmacology approach and molecular docking. METHODS: Active ingredients, targets of Shanmei Capsule as well as targets for hyperlipidemia were screened based on database. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment were performed via Database for Annotation, Visualization, and Integrated Discovery (DAVID) 6.8 database. Ingredient-target-disease-pathway network was visualized utilizing Cytoscape software and molecular docking was performed by Autodock Vina. RESULTS: Seventeen active ingredients in Shanmei Capsule were screened out with a closely connection with 34 hyperlipidemia-related targets. GO analysis revealed 40 biological processes, 5 cellular components and 29 molecular functions. A total of 15 signal pathways were enriched by KEGG pathway enrichment analysis. The docking results indicated that the binding activities of key ingredients for PPAR-α are equivalent to that of the positive drug lifibrate. CONCLUSIONS: The possible molecular mechanism mainly involved PPAR signaling pathway, Bile secretion and TNF signaling pathway via acting on MAPK8, PPARγ, MMP9, PPARα, FABP4 and NOS2 targets.
