[Objectives] To further explore the mechanism of quercetin regulating the activity of Sune-1 cells. [Methods] High-throughput mRNA-miRNA transcriptome sequencing technology was used to screen miRNA in Sune-1 cells treated with quercetin. [Results] Statistical analysis showed that 1 264 miRNAs were differentially expressed in Sune-1 cells treated with quercetin, of which 716 were significantly up-regulated and 548 were significantly down-regulated; 191 miRNAs were differentially expressed in Sune-1 cells treated with quercetin, of which 129 were significantly up-regulated and 62 were significantly down-regulated. By comparing the expression differences of these mRNAs and miRNAs in different samples, six different expression patterns were clustered. The expression of the above miRNAs was verified by real-time quantitative PCR (qPCR), and the results were highly consistent with the transcriptome sequencing data. In addition, Gene Ontology annotation and functional enrichment analysis of miRNA target genes showed that CTGF, VHL and H19, which are related to the regulation of cell proliferation signal transduction, were predicted to be new targets of differential miRNAs such as miR494-3p and miR675-3p and may play an important regulatory role in the process of Quercetin inhibiting the proliferation of Sune-1 cells. [Conclusions] This study provides a basis for the rational use of anti-tumor functional components of traditional Chinese medicine, and also provides a theoretical basis for the targeted therapy of nasopharyngeal carcinoma. |
