Differential expression analysis of GSE10334 and GSE54710. A, Volcano plot of mRNA expression level in GSE10334, mRNAs with adjusted P value <.01 and log2(FC) >1.0 are shown by the red dot, whereas mRNAs with adjusted P value <.01 and log2(FC) <−1 are shown by the blue dot. B, Volcano plot of miRNAs expression level in GSE54710, miRNAs, with P value <.05 and log2(FC) >0.5 are shown by the red dot, whereas miRNAs with P value <.05 and log2(FC) <−0.5, are shown by the blue dot. C, The heatmap shows the expression of the top 20 up-regulated mRNAs and down-regulated mRNAs. D, The heatmap shows the expression of the top 20 up-regulated miRNAs and down-regulated miRNAs. E, The Venn diagram shows the overlapping parts of the differentially expressed genes (DEGs) and ferroptosis-related genes (FRGs), identifying 7 differentially expressed ferroptosis-related genes (DE-FRGs). F, Spearman correlation analysis of the 7 DE-FRGs.
