Gene expression profiling of high (HAB) vs. low (LAB) anxiety-related behavior mice in seven brain regions.

ABSTRACT: Investigating the molecular basis and correlates of anxiety-related and depression-like behaviors, we generated a mouse model consisting of high (HAB) and low (LAB) anxiety-related behavior mice. We utilized the elevated plus-maze for testing the genetic predisposition to anxiety-related behavior and, consequently, used this as selection criterion for the inbreeding of our animals. In depression-related tests, HAB mice display a more passive, depression-like coping strategy than LAB mice, resembling clinical comorbidity of anxiety and depression as observed in psychiatric patients. Using a microarray approach, the hypothalamic paraventricular nucleus (PVN), the basolateral/lateral (BLA), the medial (MeA) and central amygdala (CeA), the nucleus accumbens (NAc), the cingulate cortex (Cg) and the supraoptic nucleus (SON) – centers of the central nervous anxiety and fear circuitries – were investigated and screened for differences between HAB and LAB mice.

Low-dose Copper exposure exacerbates depression-like behavior in ApoE4 transgenic mice

Project description:Depression is one of the most common neuropsychiatric disorders. Although the pathogenesis of depression is still unknown, environmental risk factors and genetics are implicated. Copper (Cu), a cofactor of multiple enzymes, is involved in regulating depression-related processes. Depressed patients carrying the apolipoprotein ε4 allele display more severe depressive symptoms, indicating that ApoE4 is closely associated with an increased risk of depression. The study explored the effect of low-dose Cu (0.13 ppm) exposure and ApoE4 on depression-like behavior of mice and further investigate the possible mechanisms. The 4-month-old ApoE4 mice and wild-type (WT) mice were treated with 0.13 ppm CuCl2 for 4 months. After the treatment, ApoE4 mice displayed obvious depression-like behavior compared with the WT mice, and Cu exposure further exacerbated the depression-like behavior of ApoE4 mice. There was no significant difference in anxiety behavior (Open field test) and memory behavior (Morris water maze). Proteomic analysis revealed that the differentially expressed proteins between Cu-exposed and non-exposed ApoE4 mice were mainly involved in Ras signaling pathway, protein export, axon guidance, serotonergic synapse, GABAergic synapse, dopaminergic synapse. Among these differentially expressed proteins, immune response and synaptic function are highly correlated. Representative protein expression changes are quantified by Western blot, showing consistent results as determined by proteomic analysis. Hippocampal astrocytes and microglia were increased in Cu-exposed ApoE4 mice, suggesting that neuroglial cells played an important role in the pathogenesis of depression. Taken together, our study demonstrated that Cu exposure exacerbates depression-like behavior of ApoE4 mice and the mechanisms may involve the dysregulation of synaptic function and immune response, and overactivation of neuroinflammation.

Adolescent Social Isolation Reprograms the Medial Amygdala: Transcriptome and Sex Differences in Reward

Project description:Adolescence is a sensitive window for reward- and stress-associated behavior. Although stress during this period causes long-term changes in behavior in males, how females respond is relatively unknown. Here we show that social isolation stress in adolescence, but not adulthood, induces persistent but opposite effects on anxiety- and cocaine-related behaviors in male vs. female mice, and that these effects are reflected in transcriptional profiles within the adult medial amygdala (meA). By integrating differential gene expression with co-expression network analyses, we identified crystallin mu (Crym), a thyroid hormone binding protein, as a key driver of these transcriptional profiles. Manipulation of Crym specifically within adult meA neurons recapitulates the behavioral and transcriptional effects of social isolation and re-opens a window of plasticity that is otherwise closed. Our results establish that meA is essential for sex-specific responses to stressful and rewarding stimuli through transcriptional programming that occurs during adolescence.

Gene expression within the prefrontal cortex and amygdala in a developing model of high and low anixety and depression-like behavior in rats

Project description:Individual differences in human temperament can increase the risk of psychiatric disorders like depression and anxiety. Our laboratory utilized a rat model of temperamental differences to assess neurodevelopmental factors underlying emotional behavior differences. Rats selectively bred for low novelty exploration (Low Responders, LR) display high levels of anxiety- and depression-like behavior compared to High Novelty Responder (HR) rats. Using transcriptome profiling, the present study uncovered vast gene expression differences in the early postnatal HR versus LR limbic brain, including changes in genes involved in cellular metabolism. These data led us to hypothesize that rats prone to high (versus low) anxiety/depression-like behavior exhibit distinct patterns of brain metabolism during the first weeks of life, which may reflect disparate patterns of synaptogenesis and brain circuit development. All samples were generated from Sprague-Dawley male rats selectively bred for high novelty response (HRs) or low novelty response (LRs).

MAPK Signaling Determines Anxiety in the Juvenile Mouse Brain but Depression-like Behavior in Adults

Project description:MAP kinase signaling has been implicated in brain development, long-term memory, and the response to antidepressants. Inducible Braf knockout mice enabled us to unravel a new role of neuronal MAPK signaling for emotional behavior. Braf mice that were induced during adulthood showed normal anxiety but increased depression-like behavior, in accordance with pharmacological findings. In contrast, the inactivation of Braf in the juvenile brain leads to normal depression-like behavior but decreased anxiety in adults. In these mutants we found no alteration of GABAergic neurotransmission but reduced neuronal arborization in the dentate gyrus. Analysis of gene expression in the hippocampus revealed nine downregulated MAPK target genes that represent candidates to cause the mutant phenotype. Our results reveal the differential function of MAPK signaling in juvenile and adult life phases and emphasize the early postnatal period as critical for the determination of anxiety in adults. Moreover, these results validate inducible gene inactivation as new valuable approach, allowing to discriminate between gene function in the adult and the developing postnatal brain.

Epigenetic intersection of BDNF Val66Met genotype with premenstrual dysphoric disorder transcriptome in a cross-species model of estradiol add-back

Project description:Ovariectomized BDNF Val66Met mice, a model that is genetically susceptible to stress, exhibited anxiety- and depression-like behavior when treated with estradiol when compared to wild type mice. Comparing ventral hippocampus of these mice with lymphoblastoid cell line cultures of control women and women with prementrual dysphoric disorder revealed common epigenetic biomarkers that transcend species and cell-type.
