Cancer&Entry Information

Cancer Name	glioma
ICD-0-3	NA
Methods	qPCR, Western blot, Luciferase reporter assay, in vitro knockdown
Sample	glioma tissues, cell lines ((U87, U251, LN229 and T98G)
Expression Pattern	up-regulated
Function Description	LncRNA DANCR was increased in glioma tissues and cells compared with normal brain tissues and cells. DANCR expression was positively correlated with the malignancy and poor prognosis of glioma patients. DANCR contained a binding site of miR-33a-5p. miR-33a-5p was decreased in glioma tissues and cells compared with normal brain tissues and cells. Downregulation of miR-33a-5p was positively correlated with the malignancy and poor prognosis of glioma patients. In glioma tissues, the expression of DANCR was negatively correlated with the expression of miR-33a-5p. Downregulation of DANCR increased miR-33a-5p expression. miR-33a-5p mimic reduced the luciferase of DANCR-WT but not DANCR-MUT. DANCR pull-down showed the expression of miR-33a-5p. miR-33a-5p mimic enhanced knockdown of DANCR -induced inhibition of cell proliferation, migration, and EMT, and increase of apoptosis. Anti-miR-33a-5p reversed the effects of si- DANCR on cell malignancy. Knockdown of DANCR remarkably reduced the increase of tumor volumes in xenograft mouse models. In tumor tissues, knockdown of DANCR increased the expression of miR-33a-5p, reduced EMT and increased apoptosis.
