Project description:This SuperSeries is composed of the following subset Series: GSE29724: Unsupervised hierarchical clustering of iNPCs induced by 6 or 5 TFs GSE29726: The overexpression of Pax6 affects mesenchymal to epithelial transition (MET) pathway during iPS induction in NPC. GSE29728: Overexpression of each of the 6 interfering TFs and 5 non-interfering TFs GSE29729: Selection of NPC specific Transcription factors GSE29730: Unsupervised hierarchical clustering of iHPCs induced by 9 or 10 TFs Refer to individual Series
Project description:To clarify the gene expression profile of iNPC, microarray analysis was performed using iNPCs induced by 6 TFs (Pax6, Hmga2, Etv6, Gatad2b, Nfxl1, and Esx1) and 5 TFs (Esx1 was omitted from 6 TFs). Unsupervised hierarchical clustering indicated that iNPC is expressing a global transcriptional profile more similar to that of NPCs rather than that of MEFs, and suggested that the TFs present in the pool acted as inducing TFs.
Project description:To clarify the gene expression profile of iHep, microarray analysis was performed using iHeps induced by 10 TFs (Foxg1, Lcor, Hnf3b, Hnf4a, Foxo6, Cdx2, Tcf1, Foxa3 ,Tcf2, Onecut1) and 9 TFs (Onecut1 was omitted from 10 TFs). Unsupervised hierarchical clustering indicated that iHep is expressing a global transcriptional profile more similar to that of HPCs rather than that of NPCs, and suggested that TFs present in the pool acted as inducing TFs.

Unsupervised hierarchical clustering indicated that iNPC is expressing a global transcriptional profile more similar to that of NPCs rather than that of MEFs, and suggested that the TFs present in the pool acted as inducing TFs. iNPCs were induced from MEF using 6 or 5 transcription factors. iNPCs were induced from MEF (MEFSH, derived from mice carrying IRES-Hygro in Sox allele) using retroviral vectors (pMXs-IRESNeo) of 6 or 5 transcription factors. Four weeks after the infection, Hygromycin was added and cultured for 1 week before the harvest. NSBAg2 and NSEB5-2C were used for the data of NPC. GSM396240 and GSM336010 were used for the data of ESC.GSM651349 and GSM336011 were used for the data of MEF.

Unsupervised hierarchical clustering indicated that iHep is expressing a global transcriptional profile more similar to that of HPCs rather than that of NPCs, and suggested that TFs present in the pool acted as inducing TFs. HPC (HB1 and HNG2) were established from fetal liver (E13.5) of C57BL6J and STOCK Tg(Nanog-GFP, Puro)1 Yam, respectively. iHeps were induced from NPC (NSBAg2, established from an ES cell line BAg73C2 carrying beta-geo knock-in allele in Afp) using retroviral vectors (pMXs without drug-selection markers) of 9 or 10 transcription factors. Three weeks after the infection, G418 was added and cultured for 1 week before the harvest. NSBAg2 and NSEB5-2C were used for the data of NPC. GSM396240 and GSM336010 were used for the data of ESC.
Project description:To characterize the genetic basis of hybrid male sterility in detail, we used a systems genetics approach, integrating mapping of gene expression traits with sterility phenotypes and QTL. We measured genome-wide testis expression in 305 male F2s from a cross between wild-derived inbred strains of M. musculus musculus and M. m. domesticus. We identified several thousand cis- and trans-acting QTL contributing to expression variation (eQTL). Many trans eQTL cluster into eleven ‘hotspots,’ seven of which co-localize with QTL for sterility phenotypes identified in the cross. The number and clustering of trans eQTL - but not cis eQTL - were substantially lower when mapping was restricted to a ‘fertile’ subset of mice, providing evidence that trans eQTL hotspots are related to sterility. Functional annotation of transcripts with eQTL provides insights into the biological processes disrupted by sterility loci and guides prioritization of candidate genes. Using a conditional mapping approach, we identified eQTL dependent on interactions between loci, revealing a complex system of epistasis. Our results illuminate established patterns, including the role of the X chromosome in hybrid sterility.
Project description:We use comprehensive and unsupervised transcriptome analyses to provide molecular classifications of sensory neurons in the mouse geniculate ganglion. 96 neurons were isolated on a C1 Fluodigm chip, underwent RNA-Seq, and iteratively clustered into sub-classes.
