Abstract:
Objective:To explore the potential molecular mechanism of corylin in the treatment of lung cancer. Method:A549 cells were treated with different concentrations of corylin， and their proliferation was detected using methye thiazolye telrazlium （MTT） reagent. Then the trend analysis and gene ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis were conducted to screen the key genes and pathways of corylin against A549 cell proliferation， followed by the verification of sequencing results by real-time polymerase chain reaction （Real-time PCR）. Result:Corylin inhibited the proliferation of A549 cells and regulated the expression of 4 364 genes in cells. The trend analysis revealed that these genes were clustered into 20 distinct modules， among which four were significantly down-regulated， suggesting that corylin exerted the anti-proliferation effect by inhibiting the expression of some genes. The inter-group comparison of differentially expressed genes （DEGs） showed that the elevation in the concentration of corylin resulted in more down-regulated genes but weakened proliferation， consistent with the findings by trend analysis. The GO and KEGG enrichment analysis of 278 DEGs in the high-dose corylin group demonstrated that corylin mainly changed the cellular and metabolic processes， which was attributed to its regulation of steroid biosynthesis， fatty acid metabolism， biosynthesis of unsaturated fatty acids， synthesis and degradation of ketone bodies， and steroid hormone biosynthesis. The Real-time PCR results confirmed that corylin down-regulated the mRNA expression levels of LSS， stearoyl-CoA desaturase （SCD）， 3-hydroxy-3-methylglutaryl-CoA synthase 1 （HMGCS1）， but up-regulated the mRNA expression of recombinant human angiopoietin-like protein 4 （ANGPTL4）， basically consistent with the transcriptomics results. Conclusion:Corylin inhibits A549 cell proliferation and alleviates lung cancer by targeting the related genes in lipid metabolism pathways.
