Project description:The genomic causes of inbreeding depression are poorly known. Several studies have found widespread transcriptomic alterations in inbred organisms, but it remains unclear which of these alterations are causes of the depression and which are mere responses to the ensuing physiological stress. We made a c-DNA microarray analysis in Drosophila melanogaster attempting to differentiate causes from responses of inbreeding depression. The rationale of the experiment was that, while depression is a general phenomenon producing similar consequences in different inbred lines, its first genetic causes would be different for each inbred line, as they are expected to be caused by the fixation of rare deleterious genes. Many changes in expression were common to all sets, but fourteen genes, grouped in four expression clusters, showed strong set-specific changes, and were therefore candidates to be sources of the inbreeding depression observed.

Many changes in expression were common to all sets, but fourteen genes, grouped in four expression clusters, showed strong set-specific changes, and were therefore candidates to be sources of the inbreeding depression observed. We took four sets of inbred sublines, each set descending from a different founding pair obtained from a large outbred stock, and compared the expression of the three most depressed sublines and the three least depressed sublines from each set.

Project description:Investigating the molecular basis and correlates of anxiety-related and depression-like behaviors, we generated a mouse model consisting of high (HAB), normal (NAB) 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 (BLA) and central amygdala (CeA), the cingulate cortex (Cg) and the dentate gyrus (DG) – centers of the central nervous anxiety and fear circuitries – were investigated and screened for differences between HAB, NAB and LAB mice.

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.
