Compared with adjacent normal tissues, in addition to the above 9 tumor types expressing higher levels of PKNOX1, PKNOX1 was also highly expressed in ACC(adrenocortical cancer), DLBC(diffuse large B-cell lymphoma), OV(ovarian serous cystadenocarcinoma), PAAD(pancreatic adenocarcinoma), UCEC (uterine corpus endometrioid carcinoma), GBM (glioblastoma multiforme),PCPG (pheochromocytoma&paraganglioma),UCS (uterine carcinosarcoma), LAML (acute myeloid leukemia), LGG (brain lower grade glioma), SARC (sarcoma), SKCM (skin cutaneous melanoma), and THYM (thymoma) (Figure 1B). This evidence concerns the gene PKNOX1 and paraganglioma.
