Description
FOXO1 acts as a tumor suppressor in solid tumors. The oncogenic PI3K pathway suppresses FOXO1 transcriptional activity by enforcing its nuclear exclusion upon AKT-mediated phosphorylation. We show here abundant nuclear expression of FOXO1 in Burkitt lymphoma (BL), a germinal center (GC) B cell derived lymphoma whose pathogenesis is linked to PI3K activation. Recurrent FOXO1 mutations which prevent AKT targeting and lock the transcription factor in the nucleus are used by BL to circumvent mutual exclusivity between PI3K and FOXO1 activation. Using genome editing in human and mouse lymphomas in which MYC and PI3K cooperate synergistically in tumor development we demonstrate pro-proliferative and anti-apoptotic activity of FOXO1 in BL and identify its nuclear localization as an oncogenic event in GC B cell derived lymphomagenesis.

Description
We generated knock-in mice expressing GFP under the control of the endogenous GIP (Glucose-dependent Insulinotropic Polypeptide) promoter that enable the isolation of a purified population of small intestine K cells. Using RNA-Seq, we comprehensively characterized the transcriptomes of GIP-GFP cells as well as the entire enteroendocrine lineage derived from Neurogenin3 (Ngn3)-expressing progenitors. Overall design: We interrogated the whole transcriptome of FACS-isolated small intestine GIPGFP cells using high-throughput mRNA sequencing. We also obtained the global gene expression patterns of the entire enteroendocrine cell lineage as well as the non-enteroendocrine cell population, comprising enterocytes, goblet cells and Paneth cells. To achieve this, small intestine epithelial cells from male mice resulting from the breeding of Neurogenin3 (Ngn3)-Cre mice with ROSA26-LoxP-STOP-LoxP-tomato indicator mice were isolated based on Tomato fluorescence and negative staining for CD45. Due to the small cell numbers, we constructed each of the three RNA-Seq libraries (GIPGFP, Ngn3TOMATO, and Ngn3-) using a pool of equal amounts of individual RNA samples without RNA amplification.

Description
The adoptive transfer of chimeric antigen receptor- (CAR) modified T cells is revolutionizing the treatment of B cell malignancies and has the potential to be applied to other diseases. CARs redirect T cell specificity by linking an antigen recognition domain to T cell signaling modules comprised of CD3z to provide signal 1, and CD28 or 4-1BB to provide costimulation. CD28/CD3z and 4-1BB/CD3z CARs confer differences in effector function and cell fate that affect clinical efficacy and toxicity. These differences may result from activation of divergent transcriptional programs. To gain this insight, we analyzed changes in gene expression in stimulated and resting CD28/CD3z or 4-1BB/CD3z CAR T cells. CD28/CD3z CAR stimulation initiated more marked early transcriptional changes with greater fold increases in the expression of effector molecules including GZMB, IFNG, IL2, TNF, and IL6. Direct comparison of CD28/CD3z and 4-1BB/CD3z samples stimulated for 6 hours identified 1,673 differentially expressed genes. Of these, the memory T cell-associated genes KLF2, IL7R, and FAM65B were expressed at lower levels in CD28/CD3z CAR T cells. KLF2 and IL7R are FOXO transcription factor family targets and we found that FOXO4 expression was similarly reduced in CD28/CD3z CAR T cells. CD28/CD3z CAR stimulation induces an effector T cell-like transcriptional profile that may underlie the decreased persistence and increased risks of toxicities observed with CD28/CD3z CAR T cells in early clinical trials. Overall design: Purified CD28/CD3z and 4-1BB/CD3z CAR T cells were prepared from healthy donors and stimulated by incubation with anti-CAR beads, or left unstimulated by incubation with control beads. Total RNA was harvested 6 or 24 hours after treatment. Three biological replicates for each treatment condition were prepared, yielding 24 total samples for analysis. A42 and A44 denote 4-1BB/CD3z CARs, A43 and A45 denote CD28/CD3z CARs.

Description
We used different zebrafish transgenic lines to sort macrophages, neutrophils and immature lymphoid cells from 5-6 day old zebrafish larvae and analyzed their transcriptomes. Comparison between the different transcriptomes and gene ontology analysis revealed specificities for each cell population. Comparison with previously published data showed that zebrafish larval macrophages expressed several known human M1 and M2 macrophages. Transcriptome analysis of uninfected and infected macrophages from embryos infected by of Mycobacterium marinum revealed infection induced transcriptional changes and a shift towards M1 transcriptomic signature. Overall design: Embryos were grown into egg water refresh every day and incubated for 5 or 6 days at 28°C. 0.003% 1-phenyl-2-thiourea (Sigma-Aldrich) was added after 1 day to prevent melanisation. After the incubation period, embryos were dissociated into single cell suspension by Trypsin treatment and fluorescent cells were sorted by FACS. RNA extraction and library preparation were performed as previously described. (Rougeot et al., 2014, Methods Mol Biol 1197:41-66). For infection experiments, zebrafish embryos were manually dechorionated at 24 hours post fertilization (hpf) and were infected by injection in the caudal vein of 125 colony forming unit of Mycobacterium marinum M strain expressing GFP. Infected larvae were collected for FACS sorting 5 day post infection.

Description
A characteristic feature of anaplastic large cell lymphoma (ALCL) is the significant reduction of the T-cell expression program despite its T-cell origin, a finding very similar to the loss of B-cell identity of classical Hodgkin lymphoma (cHL). Previously we demonstrated that epigenetic mechanisms are active in cHL to induce this peculiar phenotype. The results show that combined DNA demethylation and histone acetylation of T-cell lines induce an almost complete extinction of the T-cell phenotype, including the down-regulation of essential T-cell receptor signalling pathway genes such as CD3, LCK and ZAP70, as well as an up-regulation of ALCL-characteristic genes. In contrast, combined DNA demethylation and histone acetylation of ALCL cells is not able to reconstitute their T-cell phenotype. This clearly demonstrates that similar epigenetic mechanisms are active in ALCL and cHL which are responsible for the extinction of their cell type characteristic phenotype.

Description
Brief expression of pluripotency-associated factors such as Oct4, Klf4, Sox2 and c-Myc (OKSM), in combination with differentiation-inducing signals, has been reported to trigger transdifferentiation of fibroblasts into other cell types. Here we show that OKSM expression in mouse fibroblasts gives rise to both induced pluripotent stem cells (iPSCs) and induced neural stem cells (iNSCs) under conditions previously shown to induce only iNSCs. Fibroblast-derived iNSC colonies silenced retroviral transgenes and reactivated silenced X chromosomes, both hallmarks of pluripotent stem cells. Moreover, lineage tracing with an Oct4-CreER labeling system demonstrated that virtually all iNSC colonies originated from cells transiently expressing Oct4, whereas ablation of Oct4+ cells prevented iNSC formation. Lastly, an alternative transdifferentiation cocktail that lacks Oct4 and was reportedly unable to support induced pluripotency yielded iPSCs and iNSCs carrying the Oct4-CreER-derived lineage label. Together, these data suggest that iNSC generation from fibroblasts using OKSM and other pluripotency-related reprogramming factors requires passage through a transient iPSC state.
Publication Title
Lineage conversion induced by pluripotency factors involves transient passage through an iPSC stage.
