The DEGs obtained from the analysis performed for validation were further analysed for retrieving target mRNA genes obtained from our study and it was observed that GSE22820 includes TAF5L and CYP4F3 while GSE26910 involves AL022324.4, a contig sequence from one of the target genes AL022324.3 among significantly differentially expressed genes of breast cancer. This evidence concerns the gene CYP4F3 and breast cancer.
