image of Integrative Bioinformatics and Experimental Validation Reveal the Mechanistic Action of Patchouli Alcohol in Prostate Cancer Treatment

Abstract

Introduction

Prostate cancer is an androgen-dependent malignancy, and the use of androgen deprivation therapies frequently results in treatment resistance, relapse, and the development of aggressive castration-resistant tumors. Patchouli alcohol, a tricyclic sesquiterpene derived from Pogostemon cablin of the Labiatae family, has demonstrated potential in modulating inflammatory responses and tumor progression. This study aimed to investigate the mechanisms through which patchouli alcohol influences inflammatory pathways associated with prostate cancer using bioinformatics and experimental validation.

Methods

Differentially Expressed Genes (DEGs) were identified from the GSE46602 dataset, containing 36 prostate cancer and 14 normal prostate biopsy samples, using the GEO2R tool (adjusted P < 0.05). Functional annotation was performed using GO and KEGG databases, while PPI networks were constructed STRING and Cytoscape. Key hub genes were identified. To validate the bioinformatics findings, qPCR and Western blotting were employed to confirm the differential expression of selected hub genes in DU145 prostate cancer cells treated with patchouli oil.

Results

Bioinformatic analysis revealed 71 DEGs, including 35 upregulated and 36 downregulated genes. Thirteen hub genes were identified (DCK, APRT, ADK, KCNK9, ADSL, PKM, KCNK3, S100A10, ENTPD2, PKLR, ARHGEF38, TPK1, and AK5), which were enriched in pathways, such as MAPK, PI3K-Akt, Ras, and Rap1. Experimental validation confirmed the upregulation of DCK, APRT, KCNK9, ADSL, PKM, S100A10, ENTPD2, PKLR, ARHGEF38, and AK5, and the downregulation of ADK, KCNK3, and TPK1 at both the mRNA and protein levels.

Conclusion

Patchouli alcohol appears to influence multiple hub genes associated with prostate cancer progression through its modulation of key cellular signaling and metabolic pathways. These findings support its potential role as a therapeutic agent for prostate cancer.
