The highest expression level of these six genes was achieved during Stage SAHS_1, which were upregulated by 1.82 ± 0.82-, 1.92 ± 0.67-, 2.50 ± 0.66-, 4.19 ± 1.62-, 3.80 ± 0.35-, and 2.41 ± 0.39-fold in comparison with that of Stage Control in BC, ACP, MCTK, FAFA, FAD, and SAD, respectively. The gene discussed is NDUFAB1; the disease is breast cancer.
