Subsequently, the expression of the overlapping genes was analyzed in samples from GSE45001 and GSE32879.As illustrated in Figs. 3A–3B, CAT, APOA1, APOC2, HSD17B4, EHHADH, APOA2, APOE4, ACOX1, and AGXT were found to be significantly reduced in the tumor samples of the GSE45001 dataset. This evidence concerns the gene ACOX1 and neoplasm.
