GSE104867: Transcriptomics and m6A-methylome analyses in wild type and Ythdf2 deficient mouse E14.5 derived NSPCs

• Organsim mouse
• Type RNASEQ
• Target gene
• Project ARCHS4

We found that the proliferation and differentiation capabilities of NSPCs decrease significantly in Ythdf2 null mutants.To explore the underlying molecular mechanism, we performed transcriptomics and well-established m6A-methylome analyses of NSPCs dervied from wild type and Ythdf2-/- embryo brains. RNA-seq data revealed that expressions of genes enriched in neural development pathways were significantly disturbed. The inhibitory genes, like Flrt2, Ptprd, et al. in regulation of JAK-STAT cascade, which contributes to the neuroprotection and neurite outgrowth, showed increased gene expressions and m6A enrichment by m6A-seq. We identified that without the recognizing and binding of Ythdf2, the degradation of neuron differentiation related m6A-modified mRNAs were delayed in Ythdf2-/-, thereby disturbing the proliferation and differentiation of NSPCs. In summary, our findings uncovered that Ythdf2 modulates neural developmental via regulating the clearance of mRNA targets. SOURCE: Qingfei Pan (Qingfei.Pan@hotmail.com) - BGI-Shenzhen
