Project description:This experiments follows up ChIPseq experiments and aims to investigate the role of Rad50 on gene expression in drosophila larval stage 3 CNS.
Project description:Excessive activation of Hes causes stem cell hyperplasia in larval CNS. Transcriptomics of Notch induced hyperplasia and Hes induced hyperplasia were compared Using affymetrix microarray, global gene expression analysis was performed.
Project description:The goal of this project was to compare NGS derived transciptional profiles of primary larval CNS tumours and allograft tumours from two stages (first-T0 and forth-T3) in Drosophila that are induced by overactivation of N pathway in order to decipher if N regulates similar or different sets of genes as primary hypeplasias transition to malignant tumours. The results of this study show that overactivation of N negatively regulates genes related to neuronal differentiation processes genes as N hyperplasias become more malignant and that genes related to stress, metabolsim and immunity are upregulated
Project description:The goal of this project was to compare NGS derived transciptional profiles of primary larval CNS tumours and allograft tumours from two stages (first-T0 and forth-T3) in Drosophila that are induced by overactivation of two HES genes [E(spl)mγ and dpn;DM] in order to decipher if these two Hes genes control similar or different sets of genes as primary hypeplasias transition to malignant tumours. The results of this study show that overactivation of DM continues to negatively regulate neuronal differentiation genes as the DM hyperplasias become more malignant and that genes related to stress and metabolsim are upregulated
Project description:Gliogenesis in the Drosophila CNS occurs during embryogenesis and also during the postembryonic larval stages. Several glial subtypes are generated in the postembryonic CNS through the proliferation of differentiated glial cells. The genes and molecular pathways that regulate glial proliferation in the postembryonic CNS are poorly understood. In this study we aimed to use gene expressing profiling of CNS tissue enriched in glia to identify genes expressed in glial cells in the postembryonic CNS. We used microarrays to compare the gene expression profiles from the larval CNS of animals that had increased numbers of glial cells to identify genes that are expressed in glia. RNA was purified from the late third instar larval CNS from control larvae, or larvae expressing an activated form of the FGF receptor (Hlt[ACT]), or overexpressing the insulin receptor (InR) in glial cells using the glial specific driver repoGal4 to increase the number of glial cells and generate CNS tissue enriched in glia.
Project description:We assessed the differential expression of genes in the Drosophila larval CNS for the Alk mutant and control to understand how the transcriptional responce in Alk-YS mutant.
