Efficacy of Buzhong Yiqi decoction on benign prostatic hyperplasia and its possible mechanism
Abstract
OBJECTIVE: To explored the mechanism of Buzhong Yigi decoction ( BZYQD) in inhibiting prostatic cell proliferation effect. METHODS: The compounds of BZYQD consisted with eight herbs were searched in TCMSP databases and the putative targets of BZYQD were collected in Drugbank database. Then, "Benign prostatic hyperplasia" (BPH) was used to find the targets based on the GeneCards, Online Mendelian Inheritance in Man (OMIM) and Therapeutic Target Database (TTD) databases, and they were further used to collect further collect the intersection targets between BZYQD and BPH by counter-selection. Next, Herb-Compound-Target-Disease network was constructed by Cytoscape software and protein interaction network was built by Search tool for recurring instances of neighbouring genes (STRING) database. Gene Ontology (GO) enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment were analyzed by Database for Annotation, Visualization and Integrated Discovery (DAVID) database to predict the mechanism of the intersection targets. Mitogen activated protein kinase 8 (MAPK8), interleukin 6 (IL-6) and quercetin were chosen to perform molecular docking. Then 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay was to detect the bility of BPH-1 (BPH epithelial cell line) by treated with quercetin at the concentrations of 15, 30, 60, 120 μM for 12, 24, 48, 72 h. The production of IL-6, tumor necrosis factor-α (TNF-α), IL-1β and were mRNA expression…
