NORAD and colorectal carcinoma: Expression of lncRNA NORAD has been investigated in our cohort of CRC samples and colon cell lines, and resulted further increased in CRC bearing Chr20-gain versus disomic Chr20, directly related to the cell proliferation markers (CCND1 and PCNA), suggesting that NORAD is sensitive to the gene dosage associated with the increase in the number of copies of the long arm of Chr20.
