In GBM, GBMLGG, LGG, and Pheochromocytoma and Paraganglioma (PCPG), high expression of LIPT2 indicated poor DSS, while low expression of LIPT2 indicated poor DSS in KIPAN, KIRC, Kidney renal papillary cell carcinoma (KIRP), Cholangiocarcinoma (CHOL), and OV (Supplementary Fig. 2b). Here, LIPT2 is linked to cholangiocarcinoma.
