Adolescent rat social play: Amygdalar proteomic and transcriptomic data.

ABSTRACT: This data article contains the proteomic and transcriptomic data of the amygdala of adolescent rats involved in social play compared to non-behavioural animals. Social play was performed on male Sprague Dawley rats on postnatal day 38 and protein and gene expression in the amygdala was determined following behavioural testing. The protein expression was measured by analysing trypsin digested protein samples using a LTQ Orbitrap Velos mass spectrometer equipped with an Advion nanomate ESI source. The obtained tandem mass spectra were extracted by Thermo Proteome Discoverer 1.3 and the data were displayed with Scaffold v 4.5.1. The transcriptomic data were generated by llumina HiSeq 4000 system. Cuffdiff (v2.2.1) program was used to calculate RNA-seq based gene expression levels. For further interpretation of data presented in this article, please see the research article 'Proteomic and Transcriptional Profiling of Rat Amygdala Following Social Play' (Alugubelly et al. 2019).

Project description:Social play is a frequently studied behavior and it is the most characteristic form of social interaction observed in adolescent rats. Social play is necessary for adolescents to develop proper cognitive, emotional, and social competency. Deficits in social play have been observed in several neurodegenerative disorders such as autism, schizophrenia, and attention deficit hyperactivity disorder. However, the information available on neural substrates and the mechanism involved in social play is still limited. This study characterized social play by proteomic and transcriptional profiling studies. Social play was performed on male Sprague Dawley rats on postnatal day 38 and protein and gene expression in the amygdala was determined following behavioral testing. The proteomic analysis led to the identification of 170 differentially expressed proteins (p≤0.05) with 67 upregulated and 103 downregulated proteins. The transcriptomic analysis led to the identification of 188 genes (adjusted p≤0.05) with 55 upregulated and 133 downregulated genes. Based on both protein and gene expression data, DAVID analysis revealed that social play altered neurotransmitter signaling including GABAergic and glutamatergic signaling and G-protein coupled receptor (GPCR) signaling. These data suggest that the synaptic levels of GABA and glutamate increased during play. Ingenuity Pathway Analysis (IPA) confirmed these alterations. IPA also revealed that differentially expressed genes/proteins in our data had significant over representation of additional neurotransmitter signaling systems, including the opioid, serotonin, and dopamine systems, suggesting that play alters the systems involved in the regulation of reward. In addition, corticotropin-releasing hormone signaling was altered indicating that an increased level of stress occurs during play. Our data suggest that increased inhibitory GPCR signaling in these neurotransmitter pathways occurs following social play as a physiological response to regulate the induced level of reward and stress and to maintain the excitatory-inhibitory balance in the neurotransmitter systems.
