Trasncripional regulation by overexpression of constitutively active FOXO1 (CA-FOXO1) in human endothelial cells

Project description:To identify genes regulated by FOXO1, we performed RNA-seq analysis of human unbilical vein endothelial cells (HUVECs) overexpressing CA-FOXO1 by adenovirus. CA-FOXO1 is constructed by mutating three amino-acids phosphorylated by Akt, T24, S256, and S319, and is constitutively localized in the nucleus compared to wild-type FOXO1.

Expression data of cHL cell lines after FOXO1 activation

Project description:FOXO1 is highly expressed in normal B cells and in most types of non-Hodgkinl lymphoma. In Hodgkin and Reed-Sternberg cells of classical Hodgkin lymphoma(cHL) expression of FOXO1 is low or absent. We overexpressed constitutively active mutant of FOXO1 fused in frame with estrogen receptor ligand-binding domain (FOXO1(3A)ER), which can be activated by 4-Hydroxytamoxifen (4-OHT), in cHL cell lines KM-H2 and L428. Activation of the FOXO1 with 4-OHT resulted in inhibition of proliferation and apoptosis. Using gene-expression array we found that FOXO1 activates transcription of known and potential tumor suppressor genes: CDKN1B, PMAIP1, BCL2L11, TNFSF10, FBXO32, CBLB). Of note, FOXO1 repressed transcription of several cytokines and cytokine receptors, which are known tobe involved in pathogenesis of cHL (e.g. CCL5, CXCR5, TNFRSF8). Taken togather our data indicate important role of FOXO1 repression in pathogenesis of cHL. KM-H2 and L428 cells expressing constitutively active mutant of human FOXO1 fused in frame with estrogen receptor ligand-binding domain were incubated with 200 ÂµM 4-OHT or vehicle (ethanol). After 24 h, total RNA was isolated with RNeasy mini kit (QIAGEN). Microarray analyses were performed using 200 ng of total RNA as starting material and 5.5 Âµg ssDNA per hybridization (GeneChip Fluidics Station 450; Affymetrix, Santa Clara, CA). The total RNAs were amplified and labeled following the Whole Transcript (WT) Sense Target Labeling Assay (http://www.affymetrix.com). Labeled ssDNA was hybridized to Human Gene 1.0 ST Affymetrix GeneChip arrays (Affymetrix, Santa Clara, CA). The chips were scanned with a Affymetrix GeneChip Scanner 3000 and subsequent images analyzed using AffymetrixÂ® Expression Console Software (Affymetrix). Probe level data were obtained using the robust multichip average (RMA) normalization algorithm.

Transcription profiling of human CD4+ leukemia Jurkat T-cells in which the PI3K pathway is constitutively turned-on and FOXO1 transcriptional activity strongly repressed

Project description:One major effect of PI3-kinase activation downstream of the serine/threonine kinase Akt is the phosphorylation of the transcription factor FOXO1 and its neutralization. FOXO1 has several ubiquitous targets genes in many cell types that control cell quiescence, oxydative stress or apoptosis. However, it has been demonstrated that FOXO1 also has specific targets depending of the cellular context. The role of FOXO1 to regulate specific genes in T lymphocytes has not been investigated yet. To examine this point, we used the CD4+ leukemia Jurkat T-cell line, in which the PI3K pathway is constitutively turned-on and FOXO1 transcriptional activity strongly repressed. These cells were transduced with lentiviruses coding for a constitutively active form of FOXO1 fused to GFP and having the three AKT phosphorylation sites mutated to alanine (FOXO1-AAA-GFP) to restore its transcriptional activity. GFP-transduced cells were used as a control and the gene activation levels in the two cell populations analyzed 48 hours post-infection.

Novel Foxo1-dependent Transcriptional Programs Control Treg Cell Function [Affymetrix gene expression data]

Project description:Regulatory T (Treg) cells characterized by expression of the transcription factor forkhead box P3 (Foxp3) maintain immune homeostasis by suppressing self-destructive immune responses1-4. Foxp3 operates as a late acting differentiation factor controlling Treg cell homeostasis and function5, whereas the early Treg cell lineage commitment is regulated by the Akt kinase and the forkhead box O (Foxo) family of transcription factors6-10. However, whether Foxo proteins act beyond the Treg cell commitment stage to control Treg cell homeostasis and function remains largely unexplored. Here we show that Foxo1 is a pivotal regulator of Treg cell function. Treg cells express high amounts of Foxo1, and display reduced T-cell receptor-induced Akt activation, Foxo1 phosphorylation, and Foxo1 nuclear exclusion. Mice with Treg cell-specific deletion of Foxo1 develop a fatal inflammatory disorder similar in severity to Foxp3-deficient mice, but without the loss of Treg cells. Genome-wide analysis of Foxo1 binding sites reveals ~300 Foxo1-bound target genes, including the proinflammatory cytokine Ifng, that do not appear to be directly regulated by Foxp3. These findings demonstrate that the evolutionarily ancient Akt-Foxo1 signaling module controls a novel genetic program indispensable for Treg cell function. Regulatory T cells were FACS sorted in WT mice (2 reps), Foxo1 KO mice (2 reps), mice expressing a constitutively active form of Foxo1 (1 rep), and Foxo1 KO mice expressing constitutively active Foxo1. We identified genes differentially expressed in WT vs. KO mice and assessed whether expression was recovered in the KO in presence of constitutively active Foxo1
