Molecular profiling of {MPS1} gene silencing in {U251} glioma cell line

摘要

Abstract Aneuploidy has been recognized as a common characteristic of cancers. Aneuploidy frequently results from errors of the mitotic checkpoint, the major cell cycle control mechanism that acts to prevent chromosome missegregation. Mutation of the genes that control chromosome segregation during mitosis may explain the high rate of chromosomal instability and aneuploidy, a characteristic of most solid tumors, including glioblastoma (GBM) (Gordon et al., 2012 [1]; Singh et al., 2012 [2]). Monopolar spindle 1 (MPS1) is an essential spindle assembly checkpoint kinase that is overexpressed in several human cancers (Kilpinen et al., 2010 [3]; Mills et al., 1992 [4]; Yuan et al., 2006 [5]). In our previous publication, we have shown the role of {MPS1} kinase in {DNA} repair and enhanced radiosensitivity in {GBM} (Maachani et al., 2015 [6]). Here, we provide methodological and analytical details of that study, to compare mRNA expression profile of siMPS1-silenced {U251} cells with untransfected control, and siRNA control (siNeg) at 6, 24, and 48 h after transfection. The raw data of this study is deposited in Gene Expression Omnibus under the accession number GSE57091.
