Abstract:
Background: Wogonin, a natural flavonoid compound, represses cancer cell growth and
induces cancer cell apoptosis in diverse malignancies. However, the function of Wogonin in lung
cancer cells and its regulatory mechanism deserve to be identified.
Methods: A549 and H460 cells were treated with Wogonin, and the cell growth, apoptosis, migration
and invasion were measured by CCK-8 and EdU, flow cytometry and Transwell assays. The targeted
genes of Wogonin and lung cancer were identified from the TCMSP and Genecards databases,
respectively. The STRING database and Cytoscape software were used to establish a PPI network and
screen hub genes. GO and KEGG analysis was conducted to explore the functions and signal pathways
related to the hub genes. MMP1 expression in lung cancer was analyzed using the UALCAN
databases, and GSEA was performed utilizing LinkedOmics. Gelatin zymography assay was used to
detect MMP1 activity. MMP1 mRNA expression was detected by qRT-PCR. Besides, MMP1, p-AKT
and c-Myc protein were detected by Western Blot assay.
Results: Wogonin could suppress the proliferation, migration and invasion of A549 and H460 cells and
induce apoptosis. GO and KEGG enrichment analysis revealed the hub genes were mostly enriched in
re-entry into the mitotic cell cycle and apoptosis. The expression of MMP1 was markedly upregulated
in lung squamous cell carcinoma, lung adenocarcinoma tissues, and lung cancer cell lines. Wogonin
could significantly inhibit MMP1 expression and activity, and overexpression of MMP1 significantly
reversed the effect of Wogonin on the malignant phenotypes of A549 and H460 cells. Wogonin
inhibited the expression of p-AKT and c-Myc protein by regulating MMP1.
Conclusion: Wogonin can repress lung cancer cells' growth and metastatic potential and promote cell
apoptosis via repressing MMP1 expression and modulating PI3K/AKT signaling pathway.
