Abstract:
Objective: The present study aimed to investigate the therapeutic mechanism of Hedyotis
diffusa Willd (HDW) and Scutellaria barbata (SB) in ccRCC using a combination of single-cell
RNA sequencing (scRNA-seq) and network pharmacology.
Methods: The active ingredients and potential molecular targets of HDW-SB were obtained from
the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform. Gene
expression data (GSE53757) were obtained from the Gene Expression Omnibus database. The hub
genes of HDW-SB against ccRCC were identified via the protein–protein interaction network, and
further analyzed by molecular complex detection. The roles of these genes in the diagnosis and
immune infiltration of ccRCC were analyzed. The clinical significance of hub genes was verified
using scRNA-seq data (GSE121638) and molecular docking.
Results: Following the PPI network analysis, 29 hub genes of HDW-SB against ccRCC were identified.
All hub genes, except for CENPE, had significantly different expressions in tumor tissue and
a more accurate diagnosis of ccRCC. Fifteen cell clusters were defined based on the scRNA-seq
dataset, and the clusters were annotated as six cell types using marker genes. TYMS and KIAA0101
from hub genes were highly expressed in NK cells. Three active compounds, quercetin, luteolin,
and baicalein, were found to target TYMS and KIAA0101 from the compound-target interaction
network.
Conclusion: 29 hub genes of HDW-SB against ccRCC were identified and showed good performance
in terms of diagnosis and prognosis. Moreover, among these hub genes docking with the
main ingredients of HDW-SB, TYMS and KIAA0101 exerted anti-ccRCC effects through NK cells.
