Project description:FoxP2 encodes a forkhead box transcription factor required for the development of neural circuits underlying language, vocalization, and motor-skill learning. Recent genetic studies have associated FOXP2 variation with neurodevelopmental disorders (NDDs), and within the cortex, it is coexpressed and interacts with other NDD-associated transcription factors. Cortical Foxp2 is required in mice for proper social interactions, but its role in other NDD-relevant behaviors is unknown. Here, we characterized such behaviors and their potential underlying cellular and molecular mechanisms in cortex-specific Foxp2 conditional knockout mice. These mice showed deficits in reversal learning without increased anxiety or hyperactivity. In contrast, they emitted normal vocalizations save for a decrease in loudness of neonatal calls. These behavioral phenotypes were accompanied by decreases in cortical dopamine D1 receptor (D1R) expression at neonatal and adult stages, while general cortical development remained unaffected. Finally, using single-cell transcriptomics, we identified neonatal D1R-expressing cell types in frontal cortex and found changes in D1R cell type composition and gene expression upon cortical Foxp2 deletion. Together these data support a role for Foxp2 in the development of dopamine-modulated cortical circuits potentially relevant to NDDs.

Project description:In humans, mutations in the transcription factor encoding gene, FOXP2, are associated with language and Autism Spectrum (ASD) Disorders, the latter characterized by deficits in social interactions. However, little is known regarding the function of Foxp2 in male or female social behavior. Our previous studies in mice revealed high expression of Foxp2 within the medial subnucleus of the amygdala (MeA), a limbic brain region highly implicated in innate social behaviors such as mating, aggression, and parental care. Here, using a comprehensive panel of behavioral tests in male and female Foxp2+/- heterozygous mice, we investigated the role Foxp2 plays in MeA-linked innate social behaviors. We reveal significant deficits in olfactory processing, social interaction, mating, aggressive and parental behaviors. Interestingly, some of these deficits displayed in a sex-specific manner. To examine the consequences of Foxp2 loss of function specifically in the MeA, we conducted a proteomic analysis of microdissected MeA tissue and found sex differences in a host of proteins implicated in neuronal communication, connectivity and dopamine signaling. Consistent with this, we discovered that MeA Foxp2-lineage cells were responsive to dopamine with differences between males and females. Thus, our findings reveal a central and sex-specific role for Foxp2 in social behavior and MeA function.

Project description:It has been proposed that two amino acid substitutions in the transcription factor FOXP2 have been positively selected during human evolution due to effects on aspects of speech and language. Here, we introduce these substitutions into the endogenous Foxp2 gene.of mice. Although these mice are generally healthy, they have qualitatively different ultrasonic vocalizations, decreased exploratory behavior and decreased dopamine concentrations in the brain suggesting an effect of the humanized Foxp2 allele on basal ganglia. In the striatum, a part of the basal ganglia that is affected in humans with a speech deficit due to one non-functional FOXP2 allele, we find that medium spiny neurons have increased dendrite lengths and increased synaptic plasticity. Since mice carrying one non-functional Foxp2 allele show opposite effects, this suggests that alterations in cortico-basal ganglia circuits might have been important for the evolution of speech and language in humans. In this particular experiment, we investigate the effects of human Foxp2 (Foxp2hum) and the non-functional Foxp2 allele on striatal gene expression in embryonic, young and adult mice. We determined genome-wide gene expression patterns in striatal biopsies from Foxp2hum/hum, Foxp2wt/ko and Foxp2wt/wt mice using high-density oligonucleotide arrays. The animals were derived from two independent FoxP2 knock-in strains and one knock-out strain. In total 71 animals were used, 29 males and 42 females. The mice ages were E16.5, P15, P18, P21 and P95 when sacrificed. The microarrays were processed in totally six batches.

Project description:Foxp2 heterozygous mice and wildtype mice were injected with cocaine or saline, 1h post-injection nucleus acumbens RNA was extracted and analysed We have tested a potential role for the transcription factor Foxp2 in dopamine signaling and reward associated synaptic plasticity and behavior. We found that Foxp2 is acutely downregulated in reward associated circuits in the nucleus accumbens following a single injection of cocaine. In Foxp2 heterozygous mutant mice, loss of transcriptional suppression by Foxp2 causes an increased constitutive expression of dopamine signaling related genes which corresponds with impairments in synaptic plasticity and reward associated behaviors.

Project description:Genetic disruptions of the forkhead box transcription factor FOXP2 in humans cause an autosomal-dominant speech and language disorder. While FOXP2 expression pattern are highly conserved, its role in specific brain areas for mammalian social behaviors remains largely unknown. Here we studied mice carrying a homozygous cortical Foxp2 deletion. The postnatal development and gross morphological architecture of mutant mice was indistinguishable from wildtype (WT) littermates. Unbiased behavioral profiling of adult mice revealed abnormalities in approach behavior towards conspecifics as well as in the reciprocal responses of WT interaction partners. Furthermore mutant mice showed alterations in acoustical parameters of ultrasonic vocalizations (USV), which also differed in function of the social context. Cell type-specific gene expression profiling of cortical pyramidal neurons revealed aberrant regulation of genes involved in social behavior. In particular Foxp2 mutants showed the downregulation of Mint2 (Apba2), a gene involved in approach behavior in mice and autism spectrum disorder in humans. Taken together these data demonstrate that cortical Foxp2 is required for normal social behaviors in mice.

Project description:Alterations to corticostriatal glutamatergic function are early pathophysiological changes associated with Huntington?s disease (HD). The factors that regulate the maintenance of corticostriatal glutamatergic synapses post-developmentally are not well understood. Recently, the striatum-enriched transcription factor Foxp2 was implicated in the development of these synapses. Here we show that, in mice, overexpression of Foxp2 in the adult striatum of two models of HD leads to rescue of HD-associated behaviors, while knockdown of Foxp2 in wild-type mice leads to development of HD-associated behaviors. We note that Foxp2 encodes the longest polyglutamine repeat protein in the human reference genome, and we show that it can be sequestered into aggregates with polyglutamine-expanded mutant Huntingtin protein (mHTT). Foxp2 overexpression in HD model mice leads to altered expression of several genes associated with synaptic function, genes which present new targets for normalization of corticostriatal dysfunction in HD.

Project description:We observed different gene expression by overexpressing the transcription factor FOXP2 in U2OS cells compared to mock-transfected cells. Additionally, we found β-catenin as co-activator binding directly to FOXP2. Activation of Wnt signaling was changing the transcriptional activity of FOXP2. Other functional and regulatory elements were found within FOXP2 and were confirmed by RNA-Seq.
