The GO analysis showed that NQO1 was closely related to the quinone metabolic process, which is involved in several biological processes, including the regulation of the quinone and the reactive oxygen species metabolic processes, positive regulation of DNA transcription processes, biosynthesis of cofactors, NAD(P)H dehydrogenase (quinone) activity, the cellular amide metabolic process, nucleobase-containing compound biosynthetic process, nucleo-cytoplasmic transport, parkinson disease, leukocyte differentiation, and protein homodimerization activity (Figure 6C). This evidence concerns the gene NQO1 and Parkinson disease.
