GSE124243: Comparing the transcriptoms of Mettl14fl/fl and Mettl14 fl/fl; Olig2-Cre oligodendrocyre precursor cell (OPCs) and mature oligodendrocytes using Next Generation Sequencing

Bulk RNA sequencing

The goal of the experiment is to determine the transcriptome alternation of Mettl14 gene inactivation in different oligodendrocyte lineage cells(OPCs and mature oligodendrocytes), by comparing the Mettl14 fl/fl; Olig2-Cre(mutant) and Mettl14fl/fl(control) OPC and mature oligodendrocyte transcriptoms.; Method: RNA collected from Mettl14fl/fl control and Mettl14fl/fl;Olig2-Cre OPC and oligodendrocytes was collected by standard protocols, sequenced using next generation high throughput sequencing technology, and processed in triplicate to produce a transcriptome profile deliminating the variable gene expression in the mutant cells.; Results: We identified 11809 transcripts present in the OPC transcriptome, 586 were significantly upregulated and 177 were significantly downregulated in the mutant cells; Among 12,542 transcripts present in mature oligodendrocytes, 1388 transcripts were upregulated and 1247 were downregulated in the mutant cells(significance: q-value<0.001; fold changes (FC) that exceed 2.0 fold (log2 |FC|>1) in expression and an expression level that exceeds two counted transcripts per million (log2 |CPM| >1)); Conclusions: Mettl14 ablation differentially alters the OPC and oligodendrocyte transcriptomes SOURCE: Huan Xu (huan816723@gmail.com) - University of Chicago
