In human temporal lobe epilepsy as well as in experimentally induced epilepsy following unilateral kainate injection into the hippocampus, Reelin expression is significantly decreased, associated with an increased migratory activity of granule cells in the dentate gyrus, termed granule cell dispersion (Haas et al., 2002; Heinrich et al., 2006; Frotscher & Haas, 2009).

Moreover, Reelin expression was found to be altered in a variety of neuropsychiatric diseases such as schizophrenia (Impagnatiello et al., 1998), major depression (Fatemi et al., 2000), autism (Fatemi, 2002) and Alzheimer’s disease (Botella-Lopez et al., 2006; for reviews see Knuesel, 2010; Frotscher, 2010). To what extent decreased Reelin expression in these diseases also affects the location of SPNs in the spinal cord remains to be investigated. click here This work was supported by the

“In response to a change in the direction of gravity, morphogenetic changes of fruiting bodies of fungi are usually observed as gravitropism. Although gravitropism in higher fungi has been studied for over 100 years, there is no convincing evidence regarding the graviperception mechanism in mushrooms. To understand gravitropism in mushrooms, we isolated differentially expressed genes in Pleurotus ostreatus (oyster mushroom) fruiting bodies developed under three-dimensional clinostat-simulated

microgravity. Subtractive hybridization, cDNA representational difference analysis was used for gene analysis and resulted in the isolation of 36 individual genes (17 upregulated and 19 downregulated) under clinorotation. The phenotype of fruiting bodies developed under simulated microgravity vividly depicted the gravitropism in mushrooms. Our results suggest that the differentially expressed genes responding to gravitational change are involved in several potential cellular mechanisms during fruiting body formation of P. ostreatus. In most basidiomycetous fungi, the characteristic morphological development, fruiting body formation, is required for sexual reproduction involving the production of a large number of basidiospores (Kües, 2000).
