Project description:Transcription profiling by array of mouse male retinas to investigate IGF-I-induced chronic gliosis and retinal stress IGF-I exert multiple effects in different retinal cell populations in both physiological and pathological conditions. Transgenic mice overexpressing IGF-I in the retina showed impaired electroretinographic responses at 6-7 months of age that worsen with age. This retinal neuronal dysfunction was correlated with the loss of rod photoreceptors, bipolar, ganglion and amacrines cells. Neuronal alterations were preceded by the overexpression of retinal stress markers, acute phase proteins and gliosis-related genes. IGF-I overexpression leads to chronic gliosis and microgliosis in TgIGF-I retinas, with mild oxidative stress, impaired recycling of glutamate and defective potassium buffering. These impaired supportive functions can contribute to neurodegeneration in TgIGF-I retinas, together with the increased production of pro-inflammatory cytokines, potential mediators of neuronal death.

Project description:For Samples GSM601017-28: The aim of this study was to use expression profiling to define transcriptional patterns and regulatory pathways that characterize the host liver response to E. multilocularis infection in the experimental model of secondary infection, to compare gene expression in this model to those described in the model of "primary infection", and to follow the changes in gene expression and in the expression of a cell proliferation marker over time during the complete chronic phase of E.multilocularis infection, following early and middle stages. For Samples GSM601029-40: The aim of this study was to use expression profiling to define transcriptional patterns and regulatory pathways that characterize the host liver response to E. multilocularis infection in the experimental model of secondary infection, to compare gene expression in this model to those described in the model of "primary infection", and to follow the changes in gene expression and in the expression of a cell proliferation marker over time during the complete chronic phase of E.multilocularis infection, following its middle and late stages. For Samples GSM601017-28: The anterior liver tissue sample of control mice group and alveolar echinococcosis mice group were obtained at each time point(1 month and 3 month). Biological replicates is 3. Then, total RNA from anterior liver of both groups were used as test sample, which labelled cy5 fluorescein, and the pool RNA of healthy BALB/c mice anterior liver was used as reference sample, which labelled cy3 fluorescein, and then hybridized to 32K Mouse Genome Array Genechips, representing about 25000 characterized murine genes. For Samples GSM601029-40: The anterior liver tissue sample of control mice group and alveolar echinococcosis mice group were obtained at each time point(2 month and 6 month). Biological replicates is 3. Then, total RNA from anterior liver of both groups were used as test sample, which labelled cy5 fluorescein, and the pool RNA of healthy BALB/c mice anterior liver was used as reference sample, which labelled cy3 fluorescein, and then hybridized to 36K Mouse Genome Array Genechips, representing about 25000 characterized murine genes.
