Abstract
Melanoma is a complex and genetically heterogeneous malignant tumor with high rates of mortality. Although current therapies provide a short-term clinical benefit, they are unable to cure the majority of patients with metastatic melanoma. Therefore, the investigation of pathological mechanisms and the development of new therapy strategies for melanoma are of great significance. Quercetin can effectively inhibit tumor growth in various tumors. However, the exact action mechanisms of quercetin against melanoma have not been comprehensively clarified, which limits its application. Accumulating evidence has suggested that the dysfunction of mitochondria is closely linked to carcinogenesis, and a better understanding of the regulation of mitochondria-related genes will shed light on providing new therapies for melanoma. In this study, we performed RNA-seq from melanoma B16-F1 cells treated with quercetin versus controls and screened for differentially expressed genes (DEGs). GO and KEGG enrichment analyses were performed, and a protein-protein interaction (PPI) network was constructed. Combining the results of RNA-seq, molecular docking, and bioinformatics analysis, we found six mitochondria-related genes, BTG2, CP, LRIG1, CYP1A1, GBP2, and MBNL1, which might be targets of quercetin in melanoma and provide an available targeting therapy strategy for melanoma.
