GO analyses uncovered that the common DEGs of both diseases were functionally related to biological pathways such as “apoptotic process,” “negative regulation of blood vessel endothelial cell migration,” and “xenobiotic metabolic process.” Moreover, they were enriched in molecular activities including “zinc ion binding,” “gluconokinase activity,” and “metalloendopeptidase activity.” Genetic variants of xenobiotic metabolism genes have been associated with the risk of breast cancer [21]. The gene discussed is IDNK; the disease is breast cancer.
