A Volcano plot of differential gene distribution after NOD2 overexpression in SK-MEL-110 melanoma cells. B, C GO analysis of the top 30 downregulated genes (B) and KEGG analysis of the top 20 downregulated genes (C) in NOD2 overexpressing SK-MEL-110 melanoma cells. D, E GEPIA database analysis of mRNA expression of TYMS and PLK1 in melanoma and normal tissues. F, G Real-time PCR determination of mRNA expression of TYMS, PLK1 after NOD2 overexpression and knockdown in A875 and SK-MEL-110 cells (F) and Western blot determination of protein levels of TYMS, PLK1, and p-PLK1 (G). H ELISA kit evaluates TYMS activity after NOD2 overexpression and knockdown in A875 and SK-MEL-110 cells. Data are expressed as the mean ± SD. Student’s t-test and one-way ANOVA were used to compare the differences. *P < 0.05, **P < 0.01, ***P < 0.001.
