Description
The mature CNS contains PDGFRA+ oligodendrocyte progenitor cells (OPC) which may remain quiescent, proliferate, or differentiate into oligodendrocytes. In human gliomas, rapidly proliferating Olig2+ cells resembling OPCs are frequently observed. We sought to identify, in vivo, candidate pathways uniquely required for OPC differentiation or quiescence. Using the bacTRAP methodology, we generated and analyzed mouse lines for translational profiling the major cells types (including OPCs), in the normal mouse brain. We then profiled oligodendoglial (Olig2+) cells from a mouse model of Pdgf-driven glioma. This analysis confirmed that Olig2+ tumor cells are most similar to OPCs, yet, it identified differences in key progenitor genes - candidates for promotion of differentiation or quiescence.

Description
We tested how complete or partial loss of endophilin A1, A2 and A3 affects gene expression in mouse hippocampus. Total loss of endophilin (triple knock-outs, TKO) was assessed in newborn mice, since the TKO mice only survive only several hours after birth. Partial loss of endophilin (endoA1,A2 double knock-out, DKO) was assessed between Overall design: 2-3 weeks of age (p13-21).

Description
Nuclear receptors (NRs) are ligand-activated transcription factors regulating a large variety of processes involved in reproduction, development, and metabolism. NRs are ideal drug targets. Immortalized cell lines recapitulate NR biology very poorly and primary cultures are laborious and require a constant need for donor material. There is a clear need for development of novel preclinical model systems that better resemble human physiology since technical uncertainty early in drug development is the cause of many preclinical drugs not reaching the clinic. Here, we studied whether organoids, mini-organs derived from the respective tissues stem cells, can serve as a novel (preclinical) model system to study NR biology and targeteability. We characterized mRNA expression profiles of the NR superfamily in mouse liver, ileum, and colon organoids. NR mRNA expression patterns were similar to the respective tissues, indicating their suitability for NR research. Metabolic NRs Fxr, Lxr, Lxr, Ppar, and Ppar were responsive to ligands in an NR-dependent fashion, as demonstrated by regulation of expression and binding to endogenous target genes. Transcriptome analyses of wildtype colonic organoids stimulated with Rosiglitazone showed that lipid metabolism was the highest significant changed function, greatly mimicking the known function of PPARs and Rosiglitazone in vivo. In conclusion, our results demonstrate that organoids constitutes a versatile and promising in vitro system to study NR biology and targeteability.

Description
We describe a critical role for Cdk6 in JAK2V617F+ MPN evolution. The absence of Cdk6 ameliorates clinical symptoms and prolongs survival of JAK2V617F fl/+ vav-Cre mice. The Cdk6 protein interferes with three hallmarks of disease: besides regulating malignant stem cell quiescence, it promotes NFkB signaling and contributes to cytokine production while inhibiting apoptosis. The treatment with palbociclib did not mirror these effects, showing that the functions of Cdk6 in MPN pathogenesis are largely kinase-independent. Overall design: LSK-sorted (FACS) bone marrow cells from 8-week-old VavCre;Jak2+/+; Cdk6+/+, VavCre;Jak2V617F; Cdk6+/+, VavCre;Jak2V617F; Cdk6-/-, VavCre; Jak2+/+; Cdk6-/- mice, and the same cell type from palbociclib-treated (38mg/kg, 3x in one week) VavCre;Jak2V617F; Cdk6+/+ mice, n=3 for all genotypes

Description
This was a collaborative study to discover somatic mutations in 188 lung adenocarcinomas. DNA sequencing of 623 genes with known or potential relationships to cancer revealed more than 1,000 somatic mutations across the samples. Our analysis identified 26 genes that are mutated at significantly high frequencies and thus are likely to play a role in carcinogenesis. The observed mutational profiles correlate with clinical features, smoking status, and DNA repair defects. These results are complemented by data integration including SNP array data and gene expression array data (deposited here). Our findings shed further light on several key signaling pathways involved in lung adenocarcinoma, and suggest new molecular targets for treatment.
