Description
Gliomas can originate upon transformation of adult Neural Progenitor Cells (NPCs) to Tumor Initiating Cells (TICs). Studies on human Glioma TICs (GTICs) have focused on the use of primary tumors from which GTICs could be isolated. Therefore investigations on the driver events underlying NPC transformation and human glioma initiation remain limited to the use of human embryonic material. Here we report on the development of strategies for the modeling of human gliomagenesis based on the use of human induced Pluripotent Stem Cells (hiPSCs). Transformation of hiPSC-derived NPCs (iNPCs) by defined genetic alterations led to the establishment of tractable human GTIC models suitable for studying the early steps of gliomagenesis as well as for screening studies. Dysregulation of PI3K, MAPK and p53 signaling in iNPCs led to the acquisition of functional GTIC properties. In vivo transplantation led to the formation of highly aggressive, infiltrative and heterogeneous tumors upon limited dilutions and secondary transplantation, faithfully recapitulating gliomagenesis. Metabolic modulation by chemical approaches compromised GTIC viability. Pilot screening of 101 anti-cancer compounds identified 3 molecules specifically targeting transformed iNPCs and primary GTICs. Together, our results demonstrate the potential of hiPSCs for the functional testing of putative driver mutations underlying human tumorigenesis and pave new avenues for the development of personalized cancer therapeutics.

Description
We reported transcriptional characterization of Treg and Tconv cells from thymic, splenic, and visceral adipose tissue (VAT) of vTreg53 TCR transgenic mice and control littermates. We examined the effect of Foxp3 on splenic and VAT CD4+ T cell transcriptome. We profiled gene expression in a novel PPARg+ splenic Treg population. We uncovered that the characteristic phenotype of VAT Treg cells was acquired in two stages. Overall design: Gene expression profiles of thymic, splenic, VAT Treg, Tconv, and Foxp3-transduced Tconv cells from vTreg53 TCR transgenic and PPARg reporter mice.

Description
Regulatory T cells (Tregs) are key brakes on the VAT inflammation that regulates local and systemic metabolic tenor. The cytokine, IL-33, expands and sustains the unique Treg population residing within VAT. Making use of single-cell RNA sequencing, we identified the major IL-33 producers in VAT to be particular mSC subtypes, related to but distinct from adipocyte progenitor cells. We further characterize these subsets by individually isolating them and performing bulk-RNA sequencing. We explored modulation of the VAT-mSC (VmSC) landscape with physiologic variables such as age and sex, as well as pathogenic states like obesity. We uncovered a VAT Treg:stromal-cell negative regulatory loop that keeps the potent effect of IL-33 under rein. Overall design: Gene expression profiles of VmSC subtypes from young male and female mice. 2-4 mice were pooled for each biological replicate and at least 2 biological replicates were obtained per VmSC subtype.

Description
We have determined that tenascin C (TNC) regulates the growth of human brain tumor initiating cells (BTICs). We have identified novel mechanisms by which TNC regulates BTIC growth. Analysis of the array data identified a number of genes that were altered with TNC treatment that could potentially regulate BTIC growth. The study provides the mechanistic basis for the regulation of BTIC growth with TNC.
