Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
To identify genes expressed predominantly in the ventral skin epidermal basal cells of pregnant mice, we performed DNA microarray analysis by using FACS-purified epidermal basal cells from ventral skin at 0 and 16 dpc, and dorsal skin at 16 dpc.

Description
Seckel syndrome (SS) is a rare spectrum of congenital severe microcephaly and dwarfism. One SS-causative gene is Ataxia Telangiectasia and Rad3-Related Protein (ATR), and ATR (c.2101 A>G) mutation causes skipping of exon 9, resulting in a hypomorphic ATR defect in patients. Because ATR governs DNA repair response, the mutation has been considered the cause of an impaired response to DNA replication stress in neuronal progenitor cells (NPCs), which is associated with the pathogenesis of microcephaly. However, the precise mechanism through which the mutation causes SS remains unclear. To address this issue, we established induced pluripotent stem cells (iPSCs) from fibroblasts carrying the ATR mutation and an isogenic ATR-corrected counterpart iPSC clone by genome editing. Interestingly, SS-patient-derived iPSCs (SS-iPSCs) exhibited cell type-specific splicing; exon 9 was dominantly skipped in fibroblasts and iPSC-derived NPCs, but it was included in undifferentiated iPSCs and definitive endodermal cells. SS-iPSC-derived NPCs (SS-NPCs) showed distinct expression profiles from ATR non-mutated NPCs. In SS-NPCs, abnormal mitotic spindles were observed more frequently than in gene-corrected counterparts, and the alignment of NPCs in the surface of the neurospheres was perturbed. Finally, we tested several splicing-modifying compounds and found that a CLK1 inhibitor, TG003, could pharmacologically rescue the exon 9 skipping in SS-NPCs. Furthermore, treatment with TG003 restored the function of ATR in SS-NPCs and decreased the frequency of abnormal mitotic events. In conclusion, our iPSC model of SS revealed a novel function of the ATR mutation in NPCs and NPC-specific missplicing, proving its usefulness for dissecting the pathophysiology of ATR-SS. Overall design: RNA-sequencing was conducted to identify the transcriptomic profiling of iPSC-derived cells

Description
It remains controversial whether human induced pluripotent stem cells (hiPSCs) are distinct from human embryonic stem cells (hESCs) in their molecular signatures and differentiation properties. We examined the gene expression and DNA methylation of 49 hiPSC and 10 hESC lines and identified no molecular signatures that distinguished hiPSCs from hESCs. Comparisons of the in vitro directed neural differentiation of 40 hiPSC and four hESC lines showed that most hiPSC clones were comparable to hESCs. However, in seven hiPSC clones, significant amount of undifferentiated cells persisted even after neural differentiation and resulted in teratoma formation when transplantated into mouse brains. These differentiation-defective hiPSC clones were marked by higher expression of several genes, including those expressed from long terminal repeats of human endogenous retroviruses. These data demonstrated that many hiPSC clones are indistinguishable from hESCs, while some defective hiPSC clones need to be eliminated prior to their application for regenerative medicine.

Description
We performed a global analysis of both miRNAs and mRNAs expression across sixteen human cell lines and extracted negatively correlated pairs of miRNA and mRNA which indicate miRNA-target relationship. The many of known-target of miR-124a showed negative correlation, suggesting our analysis were valid. We further extracted physically relevant miRNA-target gene pairs, applying computational target prediction algorism with inverse correlations of miRNA and mRNA expression. Furthermore, Gene Ontology-based annotation and functional enrichment analysis of the extracted miRNA-target gene pairs indicated putative functions of miRNAs.
