PTTG1 and pituitary gland adenoma: Other studies implicate lncRNAs in the regulation of pituitary adenomas and other cancers.44, 45, 46 An elevated level of lncRNA H19 expression was found in invasive pituitary adenoma cells.44 LncRNA CCAT2 has recently been found to be significantly upregulated in pituitary adenomas tissues.45 Loss‐ and gain‐of‐function assays showed that CCAT2 positively regulated pituitary adenoma cell proliferation, migration and invasion, and interacted with PTTG1 to promote its stability.
