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 ...

Alveolar rhabdomyosarcoma (aRMS) is an aggressive sarcoma of skeletal muscle characterized by expression of the PAX3-FOXO1 fusion gene. Despite its discovery over almost 20 years ago, PAX3-FOXO1 remains an enigmatic tumor driver. Previously, we reported that PAX3-FOXO1 supports aRMS initiation by en...

Adenoviral expression of a constitutive active FOXO1 vs. control GFP in human umbilical vein endothelial cells (HUVEC). Expression analysis 16 h after transduction.

The pathways regulating the formation of the germinal center (GC) dark- (DZ) and light- (LZ) zones are unknown. We show that FOXO1 expression is restricted to the GC DZ and is required for DZ formation, since its absence in mice leads to the complete loss of DZ gene programs and the formation of LZ-...

The forkhead box transcription factor FOXO1 is highly expressed in granulosa cells of growing follicles but is down-regulated by FSH in culture or by LH-induced luteinization in vivo. To analyze the function of FOXO1, we infected rat and mouse granulosa cells with adenoviral vectors expressing two F...

During a T cell response, naïve CD8 T cells differentiate into effector cells. Subsequently, a subset of effector cells termed memory precursor effector cells (MPECs) further differentiates into functionally mature memory CD8 T cells. The transcriptional network underlying this carefully scripted p...

Tight regulation of Toll-like receptor (TLR)-mediated inflammatory responses is important in innate immunity. Here, we show that T cell death-associated gene 51 (TDAG51/PHLDA1) is a novel coactivator of the transcription factor FoxO1, regulating inflammatory mediator production in the lipopolysaccha...

CD4+ and CD8+ T cells isolated from wild-type and Foxo1-deficient mice were analyzed by global gene expression profiling with Affymetrix array MOE 430 2.0. Results indicate Foxo1 regulates the expression of genes encoding positive regulators of T cell activation, differentiation, homeostasis, cell a...

The Forkhead Box, FOXO1 and FOXO3, transcription factors regulate multiple functions in mammalian cells. Selective inactivation of the Foxo1 and Foxo3 genes in murine ovarian granulosa cells severely impairs follicular development and apoptosis causing infertility, and as shown herein, granulosa cel...
