Some deregulated lncRNAs in MM also appear deregulated in the same way in other types of human cancer: for example, HOTAIR is upregulated in hepatocellular carcinoma (HCC), PDIA3P (protein disulfide isomerase family A member 3 pseudogene 1) in lung cancer, and LINC00461 in both HCC and lung cancer, all three of them being also upregulated in MM [47,48,49,54,55,56,100]. The gene discussed is HOTAIR; the disease is lung carcinoma.
