Description
This study aimed to explore the role of NIPP1 in adult germline cell proliferation and differentiation, using a ubiquitous inducible NIPP1 knockout (TKO) mouse model. To gain unbiased insight into the molecular mechanism that underly the sertoli-only phenotype in TKO, we performed a comparative RNA sequencing profiling of control and TKO, in which NIPP1 was tamoxifin-induced depleted. Overall design: Two genotypes are compared after treatment with tamoxifen. The control genotype (UBC CRE-ERT2+/- Ppp1r8 fl/+) looses the floxed allele of PPP1R8 (aka NIPP1) as a consequence of the treatment with tamoxifen and becomes heterozygous for PPP1R8. The KO genotype (UBC CRE-ERT2+/- Ppp1r8 fl/-) also looses the floxed allele of PPP1R8 as a consequence of the tamoxifen treatment and becomes homozygous KO. For each genotype, 4 replicates are profiled.

Description
Autism spectrum disorder (ASD) is a disorder of brain development believed, in most cases, to be of genetic origin. We use induced pluripotent stem cells (iPSCs)-derived 3-dimensional neural cultures (organoids) in patients with ASD and macrocephaly to investigate neurodevelopmental alterations that cause this form of ASD. By using transcriptome analyses, we identified modules of co-expressed genes significantly upregulated in ASD patients compared to non-ASD first-degree family members. Overall design: Total RNA was prepared from terminal differentiation day 0, 11 and 31 of iPSCs-derived neural cultures from ASD patients and non-ASD first-degree family members. A total of 4 patients and 8 controls (unaffected family members) were analyzed in replicates (two to three iPSC clones per person).

Description
Reprogramming human somatic cells into induced pluripotent stem cells (iPSC) has been suspected of causing de novo copy number variations (CNVs). To explore this issue, we performed a whole-genome and transcriptome analysis of 20 human iPSC lines derived from primary skin fibroblasts of 7 individuals using next-generation sequencing. We find that, on average, an iPSC line manifests two CNVs not apparent in the fibroblasts from which the iPSC was derived. Using qPCR, PCR, and digital droplet PCR (ddPCR) to amplify across the CNVs'' breakpoints, we show that at least 50% of those CNVs are present as low frequency somatic genomic variants in parental fibroblasts and are manifested in iPSC colonies due to their clonal origin. Hence, reprogramming does not necessarily lead to de novo CNVs in iPSC, since most of line-manifested CNVs reflect somatic mosaicism in the human skin. Moreover, our findings demonstrate that clonal expansion, and iPSC lines in particular, can be used as a discovery tool to reliably detect low frequency CNVs in the tissue of origin. Overall, we estimate that approximately 30% of the fibroblast cells have somatic CNVs, suggesting widespread somatic mosaicism in the human body. Our study paves the way to understanding the fundamental question of the extent to which cells of the human body normally acquire structural alterations in their DNA post-zygotically. Overall design: We have generated and characterized hiPSC lines derived from skin fibroblasts collected from seven members of two families, which were competent to be differentiated into neuronal progenitors and neurons

Description
A simultaneous engagement of different pathogen recognition receptors provides a tailor made adaptive immunity for an efficient defence against distinct pathogens. For example, cross talk of TLR and c-type lectin signalling effectively shapes distinct gene expression patterns by integrating the signals at the level of NF-B. Here, we extend this principle to a strong synergism between the Dectin-1 agonist, curdlan, and an inflammatory growth factor, GM-CSF. Both together act in synergy in inducing a strong inflammatory signature which converts immature DCs to potent effector DCs. A variety of cytokines (IL-1, IL-6, TNF-, IL-2 and IL-12p70), costimulatory molecules (CD80, CD86, CD40 and CD70), chemokines (CxCl1, CxCl2, CxCl3, CCl12, CCl17) as well as receptors and molecules involved in fugal recognition and immunity such as Mincle, Dectin-1, Dectin-2 and Pentraxin 3 are strongly up-regulated in DC treated simultaneously with curdlan and GM-CSF. The synergistic effect of both stimuli resulted in strong IKB phosphorylation, in its rapid degradation and in enhanced nuclear translocation of all NF-B subunits. We further identified MAPK ERK, as one possible integration site of both signals, since its phosphorylation was clearly augmented when curdlan was co-applied with GM-CSF. Our data demonstrate that the immunomodulatory activity of curdlan requires an additional signal provided by GM-CSF to successfully initiate a robust -glucan specific cytokine and chemokine response. The integration of both signals clearly prime and tailor a more effective innate and adaptive response against invading microbes and fungi.
