Following further analysis of ERR family gene expressions at different pathological stages, significant differences were observed in ESCA, KIPAN, THYM, and THCA for ESRRA (Supplementary Figure S1A), LUAD, KIRC, THCA, and READ tumors for ESRRB (Supplementary Figure S1B), and KIPAN, KIRC, Thymoma (THYM), THCA, TGCT, and KICH for ESRRG (Supplementary Figure S1C). Here, SLC7A1 is linked to reading.
