Project description:The roles of histone demethylase KDM7 in gene expression were analyzed by gene expression profiling experiments with mouse neuroblastoma cell line Neuro2A. Keywords: mouse neuroblastoma, Neuro2A, gene expression profiling, microarray, Affimetrix M430 2.0 chip In order to examine the effect of KDM7 in gene expression, we generated stable KDM7 knockdown cell lines in mouse neuroblastoma cell line Neuro2A. Total RNAs were extracted from 5 cell lines (parental cells: Neuro2A, empty vector: Neuro2A transfected with empty vector, EGFP KD: Neuro2A transfected with vector for EGFP knock down, KDM7 KD1: Neuro2A transfected with vector 1 for KDM7 knock down, and KDM7 KD2: Neuro2A transfected with vector 2 for KDM7 knock down) and analyzed for gene expression profiles using Affymetrix platform.

Project description:The upstream stimulating factors (USFs) USF1 and USF2 are ubiquitously expressed transcription factors characterized by a conserved basic helix-loop-helix leucine zipper DNA-binding domain. They form homo- or heterodimers and recognize E-box motifs to modulate gene expression. They are known to regulate diverse cellular functions including the cell cycle, immune response and glucose-lipid metabolism, but their roles in neuronal cells remain to be clarified. Here, we performed chromatin immunoprecipitation of USF1 from mouse brain cortex preparations. Subsequent promoter array analysis (ChIP-chip) indicated that USF1 exclusively bound to the CACGTG E-box motifs in the proximal promoter regions. Importantly, functional annotation of the USF1-binding targets revealed an enrichment of genes related to lysosomal functions. Gene expression arrays using a neuronal cell line subsequently revealed that knockdown of USFs deregulated lysosomal gene expression. Altered expression was validated by quantitative RT-PCR, supporting the conclusion that USFs regulate lysosomal gene expression. Furthermore, USFs knockdown slightly increased LysoTracker staining, implying a role for USFs in modulating lysosomal homeostasis. Together, our comprehensive, genome-scale analyses identified lysosomal genes as targets of USFs in neuronal cells, suggesting a potential additional pathway of lysosomal regulation. Gene expression profiling of neuro2a cells knocking down USFs. To screen USFs-downstream genes, mouse neuro2a cells were transfected with vectors for USFs miR RNAi or an empty vector, and then subjected to microarray analysis using Affymetrix Mouse Gene 1.0 ST Array.

Project description:PURPOSE: To provide a detailed gene expression profile of the normal postnatal mouse cornea. METHODS: Serial analysis of gene expression (SAGE) was performed on postnatal day (PN)9 and adult mouse (6 week) total corneas. The expression of selected genes was analyzed by in situ hybridization. RESULTS: A total of 64,272 PN9 and 62,206 adult tags were sequenced. Mouse corneal transcriptomes are composed of at least 19,544 and 18,509 unique mRNAs, respectively. One third of the unique tags were expressed at both stages, whereas a third was identified exclusively in PN9 or adult corneas. Three hundred thirty-four PN9 and 339 adult tags were enriched more than fivefold over other published nonocular libraries. Abundant transcripts were associated with metabolic functions, redox activities, and barrier integrity. Three members of the Ly-6/uPAR family whose functions are unknown in the cornea constitute more than 1% of the total mRNA. Aquaporin 5, epithelial membrane protein and glutathione-S-transferase (GST) omega-1, and GST alpha-4 mRNAs were preferentially expressed in distinct corneal epithelial layers, providing new markers for stratification. More than 200 tags were differentially expressed, of which 25 mediate transcription. CONCLUSIONS: In addition to providing a detailed profile of expressed genes in the PN9 and mature mouse cornea, the present SAGE data demonstrate dynamic changes in gene expression after eye opening and provide new probes for exploring corneal epithelial cell stratification, development, and function and for exploring the intricate relationship between programmed and environmentally induced gene expression in the cornea.

Project description:Menin (MEN1) is a critical modulator of tissue development and maintenance.Although menin is abundantly expressed in the nervous system, little is known with regards to its function in the adult brain. To explore molecular mechanisms associated with the phenotypes observed upon neuronal Men1 deletion, we profiled transcriptomes from the Neuro2a(N2a) cells transfected Men1 siRNA USING NimbleGen Mouse gene expression array [100718_MM9_EXP].
