Importantly, decreased levels of mitophagy-related BNIP3L and PINK1, as well as increased levels of mitochondrial biogenesis related genes PPARGC1A and PPARGC1B were found in the basal-like tumor samples when compared to the Luminal A subtype (Table 1, Supplementary Figure 1). The gene discussed is PPARGC1B; the disease is neoplasm.
