Project description:The importance of fathers' engagement in care and its critical role in the offspring’s cognitive and emotional development is now well established. Yet, little is known on the underlying neurobiology due to the lack of appropriate animal models. In the socially monogamous and bi-parental prairie vole (Microtus ochrogaster), while most virgin males show spontaneous paternal behaviors (Paternal), others display pup-directed aggression (Attackers). Here we took advantage of this phenotypic dichotomy and used RNA-sequencing in three important brain areas to characterize gene expression associated with paternal behaviors of Paternal males and compare it to experienced fathers and mothers. This strategy allowed the identification of spontaneous paternal behaviors independently from fatherhood and pair-bonding. While Paternal males displayed the same range and extent of paternal behaviors than experienced Fathers, the nucleus accumbens (NAc) and medial preoptic area (MPOA) transcriptomes mainly reflected pair-bonded status or sex differences, respectively. The lateral septum (LS) transcriptome, however, primarily reflected phenotypic differences between Paternal and Attackers and suggested the involvement of the mitochondria, RNA translation, and protein degradation processes. Altogether, these observations highlight a marked structure- and phenotype-specific pattern of gene expression underlying paternal behaviors in prairie voles and highlight similarities and differences from those underlying fatherhood.

Project description:In socially monogamous prairie voles (Microtus ochrogaster), parental behaviors not only occur in mothers and fathers, but also can exist in virgin males. However, some virgin males display aggressive behaviors towards conspecific pups. Although this behavioral dichotomy in response to pup exposure has been well documented in male virgin voles, little is known about the gene expression changes underlie the parental behavioral differences and their regulatory mechanisms. To address this, we profiled the transcriptome and DNA methylome of hippocampal dentate gyrus of four prairie vole groups, attacker virgin males, parental virgin males, fathers, and mothers. We found a concordant pattern of gene transcription in parental virgin males and fathers, when comparing to the attacker group. The methylome analysis also revealed pathways with genes enriched for epigenetic changes involving both receptor-mediated and secondary messenger signaling across both behavioral phenotypes and sexual experiences. Furthermore, we found correlations between gene expression changes and DNA methylation differences between attacker and parental virgin males, which suggests a canonical gene expression regulatory role of DNA methylation in paternal care. Therefore, our study presents an integrated view of transcriptome and epigenome that provides a DNA epigenetic based molecular insight of paternal behavior.

Project description:An Infinium microarray platform (GPL28271, HorvathMammalMethylChip40) was used to generate DNA methylation data from several tissues from prairie voles (Microtus ochrogaster). Ear, liver, and brain samples from the Cornell University prairie vole colony were collected from 48 male and female prairie voles at various life stages: neonatal (<1 month old), sub-adult (2-4 months old), mature adult (4-10 months old), and middle aged/old adult (>10 months old). The pair bonded male and female prairie voles used in our study cohabitated with their partners for several months and produced at least three generations of litters. Animals were euthanized via rapid decapitation, their tissues rapidly extracted and frozen on dry ice before being stored at -80C until further processing for genomic DNA extraction. Brains were coronally sectioned and brain regions from the pair bonding circuit (PBC) were micro-dissected and pooled for each animal. The PBC brain regions included the prefrontal cortex, nucleus accumbens, lateral septum, ventral pallidum, and medial amygdala, and ventral tegmental area. Genomic DNA was isolated and purified using the phenol-chloroform extraction and ethanol precipitation method. A total of 144 tissue samples were collected and processed for DNA methylation analysis.

Project description:BackgroundThe importance of fathers' engagement in care and its critical role in the offspring's cognitive and emotional development is now well established. Yet, little is known on the underlying neurobiology due to the lack of appropriate animal models. In the socially monogamous and bi-parental prairie vole (Microtus ochrogaster), while 60-80% of virgin males show spontaneous paternal behaviors (Paternal), others display pup-directed aggression (Attackers). Here we took advantage of this phenotypic dichotomy and used RNA-sequencing in three important brain areas to characterize gene expression associated with paternal behaviors of Paternal males and compare it to experienced Fathers and Mothers.ResultsWhile Paternal males displayed the same range and extent of paternal behaviors as experienced Fathers, we observed structure-specific transcriptomic differences between parental behaviors phenotypes. Using differential expression, gene set expression, as well as co-expression network analyses, we found that phenotypic differences between Paternal males and Attackers were mainly reflected by the lateral septum (LS), and to a lower extent, the nucleus accumbens (NAc), transcriptomes. In the medial preoptic area (MPOA), the profiles of gene expression mainly reflected differences between females and males regardless of their parental behaviors phenotype. Functional enrichment analyses of those gene sets associated with Paternal males or Attackers in the LS and the NAc revealed the involvement of processes related to the mitochondria, RNA translation, protein degradation processes, as well as epigenetic regulation of gene expression.ConclusionsBy leveraging the natural phenotypic differences in parental behaviors in virgin male prairie voles alongside fathers and mothers, we identified a marked structure- and phenotype-specific pattern of gene expression associated with spontaneous paternal behaviors independently from fatherhood and pair-bonding. The LS transcriptome related to the mitochondria, RNA translation, and protein degradation processes was thus highlighted as a primary candidate associated with the spontaneous display of paternal behaviors. Altogether, our observations further characterize the behavioral and transcriptomic signature of parental behaviors in the socially monogamous prairie vole and lay the groundwork to further our understanding of the molecular underpinnings of paternal behavior.

Project description:This dataset contains RNA sequencing results from adult male prairie voles that were in either opposite-sex or same-sex pairs that were subsequently either separated from or remained paired with their partner for either 48 hours or 4 weeks prior to collecting nucleus accumbens tissue. The goal of this experiment was to determine the nucleus accumbens transcriptional response specific to separation from an opposite-sex partner. RNA sequencing was done on polyA enriched transcripts using Illumina single-end sequencing. Samples from 3 groups were from a Ribo-seq protocol using a virally delievered, vole optimized Translating Ribosome Affinity Purification construct (Heiman et al., 2008). These samples contain files for both the input fraction and the pulldown fraction (denoted with a _P suffix).
