In addition, there was no significant difference in the P4HA1 expression between tumor and normal tissues in patients with adrenocortical carcinoma (ACC), OV, pheochromocytoma and paraganglioma (PCPG), sarcoma (SARC), testicular germ cell tumor (TGCT), or thymoma (THYM) (Supplementary Figure S4A). Here, P4HA1 is linked to pheochromocytoma.
