Project description:Expression profiling of normal NIH3T3 and transformed NIH3T3 K-ras cell lines grown for 72 hours in optimal glucose availability (25 mM glucose) or low glucose availability (1 mM). Low glucose induces apoptosis in transformed cells as compared to normal ones.

Project description:The aim of this experiment was to get a comparison of the signatures between a non-transformed cell (NIH3T3 + vector) and a transformed cell (NIH3T3 + Fbxo7). NIH3T3 cells become transformed after the stable integration of the Fbxo7 gene. Fbxo7 potentiates cyclin D/cdk6 activity.

Project description:Expression profiling of normal NIH3T3 and transformed NIH3T3 K-ras cell lines grown for 72 hours in optimal glucose availability (25 mM glucose) or low glucose availability (1 mM). Low glucose induces apoptosis in transformed cells as compared to normal ones. We performed genome-wide analysis by using Affymetrix GeneChip oligonucleotide microarrays to identify those genes whose expression levels are modulated by glucose availability in NIH3T3 and NIH3T3 K-ras cell lines. The cells, to be used for the transcription analysis, were collected at 18h from the initial seeding, time corresponding to the change of medium (25 or 1 mM glucose, indicated as T0) and then at 24, 48 and 72h upon medium change.

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:Effect of the overexpression of the oncogenic form of the Vav2 protein in the NIH3T3 cell line under serum deprivation conditions. oncovav2-transformed NIH3T3 cells grown in serum-deprived medium (Vav2SD) are compared to the parental NIH3T3 controls under the same growth conditions (ContSD). Vav2SD cells are also compared to the oncovav2-transformed NIH3T3 cells growing exponentially and the NIH3T3 growing exponentially.

Project description:Forskolin treatment induces activation of protein kinase A. This activation protects transformed cells from death induced by glucose starvation. We used microarray to identify the mechanisms involved in such a pro-survival effect. NIH3T3 and NIH3T3-K-ras were plated at 1mM glucose and then daily treated or not with 10uM FSK until 72h of growth. The microarray analysis has been performed at 72h in order to identify specific mechanisms associate with transformed cells survival.

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: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.
