The transcriptome of playfulness is sex-biased in the juvenile rat medial amygdala: a role for inhibitory neurons

ABSTRACT: Social play is a well-conserved, dynamic behavior known to be sexually differentiated. In most species, males play more than females, a sex difference largely driven by the medial amygdala (MeA) yet the full mechanism establishing this bias is unknown. Here, we explore “the transcriptome of playfulness” in both sexes for the first time, demonstrating that the transcriptomic profile in the juvenile rat MeA associated with playfulness is markedly distinct in males and females. Parallel single-cell RNA-sequencing experiments from newborn rats suggest that inhibitory neurons drive this sex difference. Furthermore, we show that inhibitory neurons comprise the majority of play-active cells in the juvenile MeA, with males having more play-active cells than females, of which a greater proportion are GABAergic. Through integrative bioinformatic analyses, we further explore the expression, function, and cell-type specificity of key play-associated gene modules, providing valuable insight into the sex-biased mechanisms underlying this fundamental social behavior.

The “play transcriptome” is sex-specific in the juvenile rat medial amygdala: a role for inhibitory neurons

Sex-specific social behavior and amygdala proteomic deficits in Foxp2+/- mutant mice

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.

Adolescent Social Isolation Reprograms the Medial Amygdala: Transcriptome and Sex Differences in Reward

Project description:Adolescence is a sensitive window for reward- and stress-associated behavior. Although stress during this period causes long-term changes in behavior in males, how females respond is relatively unknown. Here we show that social isolation stress in adolescence, but not adulthood, induces persistent but opposite effects on anxiety- and cocaine-related behaviors in male vs. female mice, and that these effects are reflected in transcriptional profiles within the adult medial amygdala (meA). By integrating differential gene expression with co-expression network analyses, we identified crystallin mu (Crym), a thyroid hormone binding protein, as a key driver of these transcriptional profiles. Manipulation of Crym specifically within adult meA neurons recapitulates the behavioral and transcriptional effects of social isolation and re-opens a window of plasticity that is otherwise closed. Our results establish that meA is essential for sex-specific responses to stressful and rewarding stimuli through transcriptional programming that occurs during adolescence.

Transcriptional profiles associated with Context dependent behavior in Rock X Sand F1 in Lake Malawi Cichlids

Project description:We sought to evaluate the brain gene expression profiles of male courtship display. To assess male display and courtship behavior, we designed a courtship preference assay. We evaluated social interactions between males and females using a 40 gallon tank design with a ‘rock’ habitat at one end and ‘sand’ at the other, separated by glass bottom. When parental rock species (Petrotilapia nigra (TaxId 526958), Maylandia zebra (TaxId 106582), Labeotropheus feulliborni) are placed in this tank paradigm, males court females over the rocks. Males of sand species (Mchenga conophorus, Aulonocara baenschi (TaxId 143496), Tramitichromis intermedius (TaxId 323801)) court females over sand and construct species appropriate bowers. When single rock x sand F1 males were placed in this set up with F1 females, males invariably courted females over the ‘rock’ habitat, suggesting genetic dominance. When two rock x sand F1 males were allowed to compete for F1 females in this tank paradigm, something interesting happened. One male, typically the larger, courted females over the rock habitat, and the other simultaneously constructed bowers to court females in the sand. We detected no difference in GSI (gonadal somatic index) between F1 males behaving as ‘socially rock’ vs. ‘socially sand.’ This observation of divergent behavior among interacting F1 brothers suggests an interaction between the genome and the social environment in these males.

Cellular evolution of the hypothalamic preoptic area of behaviorally divergent deer mice

Project description:Genetic variation is known to contribute to the variation of animal social behavior, but the molecular mechanisms that lead to behavioral differences are still not fully understood. Here, we investigate the cellular evolution of the hypothalamic medial preoptic area (MPOA), a brain region that plays a critical role in social behavior, across two sister species of deer mice (Peromyscus maniculatus and P. polionotus) with divergent social systems. These two species exhibit large differences in mating and parental care behavior across species and sex. Using single-nucleus RNA-sequencing, we build a molecular atlas of the MPOA for males and females of both Peromyscus species.

Behavioral, Neurotransmitter and Transcriptomic Analyses in male and female Fmr1 Knockout Mice

Project description:Fragile X Syndrome is an inherited X-linked disorder associated with intellectual disabilities that begin in childhood and last a lifetime. The symptoms overlap with autism spectrum disorder, and the syndrome predominantly affects males. Consequently, FXS research tends to favor analysis of social behaviors in males, leaving a gap in our understanding of other behavioral traits, especially in females. Here we used a mouse model of FXS to analyze developmental, behavioral, neurochemical, and transcriptomic profiles in males and females. Our behavioral assays demonstrated locomotor hyperactivity, motor impulsivity, increased “approach” behavior in an approach-avoidance assay, and deficits in nest building behavior. Analysis of brain neurotransmitter content revealed deficits in striatal GABA, glutamate, and serotonin content. RNA sequencing of the ventral striatum unveiled expression changes associated with neurotransmission as well as motivation and substance use pathways. Sex differences were identified in nest building behavior, striatal neurotransmitter content, and ventral striatal gene expression. In summary, our study identified sex differences in specific behavioral, neurotransmitter, and gene expression phenotypes and gene set enrichment analysis identified significant enrichment of pathways associated with motivation and drug reward.

Identification of differentially expressed genes between adult males and adult females of the two-spotted spider mite (Tetranychus urticae)

Project description:Sex-specific differences in gene expression underlie differences in morphology, behavior, and reproduction. To date, little is known about sex-specific differences in gene expression in spider mites, even though males and females differ markedly in morphology and behavior. In this study, we describe the complement of sex-specific gene expression differences between males and females of the two-spotted spider mite (Tetranychus urticae), an important generalist herbivore that is a significant crop pest. Gene expression differences were detected from analyses of mRNA-seq data collected with the Illumina method (eight samples in total consisting of four biological replicates each for males and females).
