The influence of the estrous cycle on sex differences in the rat adult medial prefrontal cortex transcriptome [ChIP-Seq]

Project description:Hormonal fluctuations throughout the ovarian cycle contribute to femalesâ?? higher vulnerability to anxiety disorders when compared to males. Notably, such sex differences are controlled by regulation of genes in the medial prefrontal cortex (mPFC) including the transcription factor early growth response 1 (Egr1) in rats, which highlights a control of anxiety-like behaviors by sexually-biased gene expression. We therefore undertook a large-scale characterization of sex differences and their interaction with the estrous cycle in the adult mPFC transcriptome and report that proestrus and diestrus females (with high and low ovarian hormones levels, respectively) exhibited a partly-opposed sexually-biased transcriptome. Surprisingly, the extent of regulations within females vastly exceeded sex differences, and support a multi-level reorganization of synaptic function across the estrous cycle. Furthermore, genome-wide analysis of Egr1 binding highlighted its role in controlling the synapse-related genes varying within females, and the sex- and estrous cycle-dependent transcriptomic reorganization in the rat mPFC. Early growth response 1 (Egr1) binding profiling in the adult rat medial prefrontal cortex of males, proestrus females, and diestrus females. A total of 9 animals were used, corresponding to 3 Males, 2 proestrus females, and 4 diestrus females.

A total of 11 samples were analyzed, corresponding to 4 males, 3 proestrus females, and 4 diestrus females.

A switch from neuronal network development to maintenance during postnatal development of rat prefrontal cortex

Project description:To unravel the gene expression changes during postnatal prefrontal cortex development, RNA-seq was performed in the rat medial prefrontal cortex at five time points from early life to adulthood (postnatal day 8, 14, 21, 35 and 70) and differential expression of protein-coding genes, lincRNAs and alternative exons was analyzed. A switch from neuronal network development to maintenance during postnatal rat prefrontal cortex development was shown.

Transcriptomic analysis of prefrontal medial cortex, hippocampus and nucleus accumbens of alcohol-preferring and nonpreferring rats

Project description:Animal models provide opportunity to study neurobiological aspects of human alcoholism. Changes in gene expression have been implicated in mediating brain function, including reward system and addiction. The current study aimed to identify novel genes that may underlie ethanol preference. Microarray analysis comparing gene expression in nucleus accumbens (NAc), hippocampus (HP) and prefrontal medial cortex (mPFC) was performed in two rat strains selected for extreme levels of ethanol preference - Warsaw High Preferring (WHP) and Warsaw Low Preferring (WLP). The identified candidate genes may underlie differential ethanol preference in rat model of alcoholism. This is analysis of 18 RNA samples, including 9 technical replicates. Two strains of rats selected for extreme levels of ethanol preference (low preferring WLP and high preferring WHP) were compared. Three brain areas (nucleus accumbens, prefrontal medial cortex and hippocampus) were studied. For each brain area, 6 RNA samples (including 3 technical replicates) were analyzed. Each RNA sample consist of of equal amounts of total RNA from 3 male rats. Comparisons: Nucleus accumbens of WHP vs. Nucleus accumbens of WLP; Prefrontal medial cortex of WHP vs. Prefrontal medial cortex of WLP; Hippocampus of WHP vs. Hippocampus of WLP. 3 biological replicates in each comparison.
