SSRI Treatment Sensitivity Assessment
Objective: Evaluate differential sensitivity to selective serotonin reuptake inhibitor (SSRI) treatment in prenatally stressed offspring, examining behavioral stress responsivity, anhedonia, and HPA axis function
This is a SSRI Treatment Sensitivity Assessment protocol using mouse as the model organism. The procedure involves 9 procedural steps. Extracted from a 2008 paper published in Journal of Neuroscience.

Prenatal Stress Exposure
Pregnant dams exposed to stress during early, mid, or late gestation to create differential prenatal stress conditions
Note: Study examined critical time windows of fetal vulnerability to stress exposure
View evidence from paper
“examined behavioral responses in offspring exposed to stress during early, mid, and late gestation”
Behavioral Assessment of Stress Responsivity
Evaluation of maladaptive behavioral stress responsivity in offspring
Note: Male offspring exposed to early gestational stress displayed maladaptive behavioral stress responsivity
View evidence from paper
“male offspring exposed to stress early in gestation displayed maladaptive behavioral stress responsivity”
Anhedonia Assessment
Measurement of anhedonia (loss of pleasure response) in prenatally stressed offspring
Note: Anhedonia was observed in male offspring exposed to early prenatal stress
View evidence from paper
“male offspring exposed to stress early in gestation displayed maladaptive behavioral stress responsivity, anhedonia”
SSRI Treatment Administration
Administration of selective serotonin reuptake inhibitor treatment to assess differential sensitivity
Note: Early prenatally stressed males showed increased sensitivity to SSRI treatment
View evidence from paper
“increased sensitivity to selective serotonin reuptake inhibitor treatment”
HPA Axis Responsivity Measurement
Assessment of hypothalamic-pituitary-adrenal axis responsivity in offspring
Note: Increased HPA axis responsivity was present in early prenatally stressed mice
View evidence from paper
“increased hypothalamic–pituitary–adrenal (HPA) axis responsivity, were present in these mice”
Gene Expression Analysis
Measurement of central corticotropin-releasing factor (CRF) and glucocorticoid receptor (GR) expression in offspring
Note: Long-term alterations in CRF and GR expression were observed
View evidence from paper
“Long-term alterations in central corticotropin-releasing factor (CRF) and glucocorticoid receptor (GR) expression”
DNA Methylation Analysis
Examination of CRF and GR gene methylation patterns in offspring
Note: Changes in CRF and GR gene methylation correlated with altered gene expression
View evidence from paper
“Changes in CRF and GR gene methylation correlated with altered gene expression”
Placental Gene Expression Assessment
Measurement of placental expression of PPAR-α, IGFBP-1, HIF3-α, and GLUT4 in male and female placentas
Note: Sex-specific differences observed: stress early in pregnancy increased expression in male placentas but not females
View evidence from paper
“stress early in pregnancy significantly increased expression of PPAR-α, IGFBP-1, HIF3-α, and GLUT4 in male placentas but not females”
Placental Epigenetic Machinery Examination
Analysis of epigenetic machinery in placental tissue to identify sex differences
Note: Basal sex differences in placental epigenetic machinery were identified
