Abstract
To investigate the effects of long non-coding RNA SPRY4-IT1 (LncRNA) on proliferation and metastasis of medul-loblastoma cells. SPRY4-IT1siRNA and control fluorescence siRNA were transfected into medulloblastoma cell line Daoy with Lipo-fe ctamine 2000 and were divided into control group and si-SPRY4-IT1 group. Relative expression of SPRY4-IT1 mRNA were detected by real-time quantitative PCR. The change of cell proliferation were examined using CCK-8 kit and clone forming experiment. The change of cell inva-sion and metastasis were examined by matrigel invasion assay and cell metastasis experiment respectively, The expression of matrix metallopro-teinase MMP-2 and MMP-9 were detected by Western blot. In si-SPRY4-IT1 group,the SPRY4-IT1 mRNA expression level, cell pro-liferation in vitro,cell invasion and migration ability, MMP-2 protein expression were significantly lower than those in the control group. Interference SPRY4-IT1 expression has prominent inhibitory effect on the cell proliferation、invasion and metastasis of medulloblastoma cell line Daoy.
