DGCR5, also known as Linc00037, was a kind of LncRNA involved in lung cancer, Huntington's disease neurodegeneration and hepatocellular carcinoma.114, 115, 116 Wang et al reported DGCR5 acted as an oncogene and revealed the possible mechanism for an interaction between DGCR and miR‐330‐5p in lung CSCs. Here, DGCR5 is linked to Huntington disease.
