Project description:Mutations in the gene encoding the transcription factor forkhead box P1 or FOXP1 occur in patients with neurodevelopmental disorders, including autism. However, the function of FOXP1 in the brain remains mostly unknown. Here, we identify the gene expression program regulated by FoxP1 in both human neural cells and mouse brain and demonstrate a conserved role for FOXP1 transcriptional regulation of autism and Fragile X Mental Retardation Protein (FMRP) mediated pathways. Coexpression networks support a role for Foxp1 in neuronal activity, and we show that Foxp1 is necessary for neuronal excitability. Using a Foxp1 mouse model, we observe defects in ultrasonic vocalizations. This behavioral phenotype is reflected at the genomic level as striatal Foxp1-regulated overlap with genes known to be important in rodent vocalizations. These data support an integral role for FOXP1 in regulating signaling pathways vulnerable in developmental disorders and the specific regulation of pathways important for vocal communication. We carried out RNA-sequencing (RNA-seq) and ChIP-sequencing of human neural progenitors cells. We carried out RNA-sequencing (RNA-seq) of mouse striatal tissue, mouse hippocampal tissue and mouse cortical tissue. For the RNA-seq, four indipendent replicates were used for the neural progenitor cells and mouse tissues. For the Chip-seq, a single neural progenitor cell line was used.

Project description:Background: Transcriptome analysis has been used in autism spectrum disorder (ASD) to unravel common pathogenic pathways based on the assumption that distinct rare genetic variants or epigenetic modifications affect common biological pathways dysregulated in ASD. To unravel recurrent ASD-related neuropathological mechanisms, we took advantage of the En2-/- mouse model and performed transcriptome profiling on cerebellar and hippocampal adult tissues. Methods: En2-/- and WT cerebellar and hippocampal tissue from littermate mice were assessed for differential gene expression using microarray hybridization followed by RankProd analysis. To identify functional categories overrepresented in the differentially expressed genes we used the BIOBASE ExPlain system and mouse phenotype ontology database. Furthermore, we performed direct enrichment analysis of ASD associated genes from the SFARI repository in our differentially expressed genes. Results: We found 842 differentially expressed genes in En2-/- cerebellum and 862 in the En2-/- hippocampus. Our functional analysis revealed that the molecular signature of En2-/- cerebellum and hippocampus shares convergent pathological pathways with ASD, including abnormal synaptic transmission, altered developmental processes and increased immune response. Furthermore, when directly compared to the repository of the SFARI database, our differentially expressed genes show enrichment of ASD-associated genes significantly higher than previously reported. Among the differentially expressed genes 20 were validated by quantitative PCR. Conclusions: Our results indicate the En2-/- mouse model of ASD as an appropriate tool to investigate molecular alterations related to ASD. En2-/- and WT cerebellar and hippocampal tissue from 3 littermates mice for each genotype was hybridized on three replicates microarrays.

Project description:Genetic perturbations of the transcription factor, Forkhead Box P1 (FOXP1), occur in patients with autism spectrum disorder who have an increased risk for comorbidity with intellectual disability. Recent work has begun to reveal an important role for Foxp1 in brain development, but the brain region-specific contribution of Foxp1 to autism and intellectual disability phenotypes has yet to be fully determined. Here, we characterize Foxp1 conditional knockout (Foxp1cKO) mice with loss of Foxp1 in the pyramidal neurons of the neocortex and the CA1/CA2 subfields of the hippocampus. Foxp1cKO mice exhibit behavioral phenotypes that are relevant to autism spectrum disorder, including hyperactivity, increased anxiety, and decreased sociability. In addition, Foxp1cKO mice have gross deficits in learning and memory tasks that are relevant to intellectual disability. Using a genome-wide approach, we identified genes differentially expressed in the hippocampus of Foxp1cKO mice that are associated with synaptic function and physiology that could represent molecular networks related to the observed behavioral deficits. Finally, we observed reduced maintenance of long-term potentiation in the CA1 subfield of these animals. Together, these data suggest that expression of Foxp1 in pyramidal neurons of the forebrain is important for regulating gene expression pathways that contribute to specific behaviors relevant to autism and intellectual disability. In particular, Foxp1 regulation of gene expression in the hippocampus appears to be crucial for normal CA1 physiology and spatial learning.

Project description:Lung cancer is one of the most common cancers in the world, which accounts for about 27% of all cancer deaths. However, the mechanisms underlying the pathogenesis of lung cancer cells remain largely elusive. In this study, we examined the role of the Forkhead box protein P1 (FOXP1) in lung cancer development. Our Oncomine analysis shows that FOXP1 is downregulated in lung adenocarcinoma compared with normal lung tissue. Knockdown of FOXP1 promotes the proliferation growth and invasion of PC9 and A549 cells by regulating genes of chemokine signaling molecules, including CCR1, ADCY5, GNG7, VAV3, and PLCB1. Simultaneous knockdown of CCR1 and FOXP1 attenuated FOXP1 knockdown-induced increase of lung cancer cell growth. Finally, knockdown of FOXP1 in PC9 cells promotes the tumorigenesis via CCR1 signaling in xenograft mouse model. Taken together, our data suggest that FOXP1 plays important roles in preventing lung adenocarcinoma development via suppressing chemokine signaling pathways. Novel strategies might be developed to prevent the development of lung adenocarcinoma by targeting FOXP1

Project description:The transcription factor FOXP1 is implicated in the pathogenesis of B-cell lymphomas through immunoglobulin heavy chain (IGH) locus-related chromosomal translocations leading to dysregulated expression of FOXP1. Translocations of FOXP1 with non-IG gene sequences have been also reported, but the molecular consequences of such aberrations remain undetermined. Here, using molecular cytogenetics and molecular biology studies, we comprehensively analyzed four lymphoma cases with non-IG rearrangements of FOXP1 and compared these with cases harboring t(3;14)(p13;q32)/IGH-FOXP1 and FOXP1-expressing lymphomas without underlying t(3p13/FOXP1). We found that non-IG rearrangements are usually acquired during evolution of lymphoma and constantly target the coding region of FOXP1, promiscuously fusing with coding and non-coding gene sequences at various reciprocal breakpoints (2q36, 10q24 and 3q11). Intriguingly, these rearrangements do not generate functional chimeric genes but commonly disrupt the full-length FOXP1 transcript leading to an aberrant expression of N-truncated FOXP1 isoforms, as shown by QRT-PCR and Western blot analysis. In contrast, cases with t(3;14)(p13;q32)/IGH-FOXP1 overexpress the full-length FOXP1. Collectively, our findings point to a dual mechanism through which FOXP1 is implicated in B-cell lymphomagenesis. The primary t(3;14)(p13;q32)/IGH-FOXP1 produces the full-length protein with potent oncogenic activity, whereas the secondary non-IG 17 rearrangements of FOXP1 generate N-truncated FOXP1 isoforms, likely driving progression of disease. Using molecular cytogenetics and molecular biology studies (including RNA-seq), we comprehensively analyzed four lymphoma cases with non-IG rearrangements of FOXP1 and compared these with cases harboring t(3;14)(p13;q32)/IGH-FOXP1 and FOXP1-expressing lymphomas without underlying t(3p13/FOXP1).
