Expressions of Hippocampal Mineralocorticoid Receptor (MR) and Glucocorticoid Receptor (GR) in the Single-Prolonged Stress-Rats
Post-traumatic stress disorder (PTSD) is a stress-related mental disorder caused by traumatic experience. | |||||||||||||||
| |||||||||||||||
|
To examine the link between PTSD and corticosteroid receptors in the hippocampus, we studied expression of MR and GR after SPS stress using immunohistochemistry and western blotting.
| |||||||||||||||
| |||||||||||||||
|
Changes of MR and GR expression in the hippocampal region between control and SPS rats are presented in Figure 3. | |||||||||||||||
| |||||||||||||||
|
It is not known whether homodimers, heterodimers, or both caused the decreased expression of MR and GR. | |||||||||||||||
| |||||||||||||||
|
Interestingly, previous studies also suggest different regulation patterns in MR and GR expression with decreased MR/GR ratio in PTSD. | |||||||||||||||

Expressions of Hippocampal Mineralocorticoid Receptor (MR) and Glucocorticoid Receptor (GR) in the Single-Prolonged Stress-Rats
Post-traumatic stress disorder (PTSD) is a stress-related mental disorder caused by traumatic experience. | |||||||||||||||
| |||||||||||||||
|
In the present study, we performed immunohistochemistry and western blotting to examine the changes in hippocampal MR- and GR-expression after SPS. | |||||||||||||||
| |||||||||||||||
|
Antidepressants increase expression of hippocampal MR and decrease basal and stress-induced HPA activity. | |||||||||||||||
| |||||||||||||||
|
Interestingly, previous studies also suggest different regulation patterns in MR and GR expression with decreased MR/GR ratio in PTSD. | |||||||||||||||
| |||||||||||||||
|
We have examined the MR/GR ratios in CA1 and whole hippocampus (Fig. 4). | |||||||||||||||
| |||||||||||||||
|
Using western blotting we disclosed the presence of MR and GR in the hippocampal area. | |||||||||||||||
| |||||||||||||||
|
Immunoreactive signals for MR, GR and ? | |||||||||||||||
| |||||||||||||||
|
The MR/GR ratios | |||||||||||||||
| |||||||||||||||
|
We found altered MR/GR ratio of both CA1-subregion and all hippocampus in the SPS animals. | |||||||||||||||
| |||||||||||||||
|
MR mRNA expression was induced in hippocampal CA1/CA2 subregions (27-37%) by all antidepressants, while moclobemide and 8-OH-DPAT significantly increased GR gene expression mainly in the CA1 region (31-44%). | |||||||||||||||
| |||||||||||||||
|
SPS produced decrease expression of MR and GR in the hippocampus. | |||||||||||||||
| |||||||||||||||
|
In present study, we examined the SPS induced down regulation of MR and GR protein expression and the change in MR/GR ratio in the hippocampus. | |||||||||||||||
| |||||||||||||||
|
Blockade of MR and GR produced anxiety and startle [13] and MR antagonism induced enhanced fear [14]. | |||||||||||||||
| |||||||||||||||
|
Selective effects on NGFI-A, MR, GR and NGFI-B hippocampal mRNA expression after chronic treatment with different subclasses of antidepressants in the rat. | |||||||||||||||
| |||||||||||||||
|
The MR or GR data in the control and SPS groups were expressed as mean±standard deviation, and by unpaired samples t-test between the groups. | |||||||||||||||
| |||||||||||||||
