Title |
The influence of the estrous cycle on sex differences in the rat adult medial prefrontal cortex transcriptome [ChIP-Seq] |
Organism |
Rattus norvegicus |
Experiment type |
Genome binding/occupancy profiling by high throughput sequencing
|
Summary |
Hormonal fluctuations throughout the ovarian cycle contribute to females’ 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.

Overall design |
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.
