For example, the network detected for pheochromocytoma and paraganglioma shows that the proteins are involved in the positive regulation of gene expression, which is also closely related to the negative regulation of H3K9 methylation function found in networks adrenocortical cancer (KDM4A overexpression), lung adenocarcinoma (KDM4A overexpression) and uterine corpus endometrioid carcinoma. Here, KDM4A is linked to lung adenocarcinoma.
