Expression data from homozygous deletion of the Lgi1 gene in murine neural precursor-like cells

ABSTRACT: The hypercellularity in the outer layers of the cortex in Lgi1 null mice suggested that Lgi1 possibly plays a role in controlling cell migration dynamics. To investigate this hypothesis, we first generated and immortalized neural precursor-like cells (NPC), isolated from Lgi1 null and wild type mice at E13.5 stage using Large-T antigen. Subsequently, we compared gene expression patterns between the immortalized NPC-like cells with the two different Lgi1 genotypes using Affymetrix GeneChip Mouse Gene 1.0 ST Array. Our studies suggest that Lgi1 has a role in regulating neuronal migration and their synapse formation and that its absence/dysregulation can result in seizure despite a histologically subtle cortical dysplastic phenotype. RNAs were extracted from the null and wild type NPC cells, respectively. The samples were biologically triplicated. RNA samples were hybridized to Mouse Gene 1.0 ST Array.

NESG1-mediated differential expression genes in nasopharyngeal carcinoma (NPC)

Project description:Analysis of differential expression genes in NESG1-overexpressed and negative nasopharyngeal carcinoma. NESG1 is a candidate tumor suppressor in NPC. Results provide insight into the molecular pathogenesis of NESG1 in NPC. NESG1 cDNA was transfected into NESG1-negative NPC 5-8F cells and affymetrix microarrays HG-U133_Plus_2 were used to analyze the differential genes in NESG1-overexpressed NPC cells and their control NESG1-negative NPC cells.

Transcriptome sequencing of nasopharyngeal carcinoma model system (miRNA)

Project description:Nasopharyngeal carcinoma (NPC) is a prevalent malignancyt disease in Southeast Asia among the Chinese population. Aberrant regulation of transcripts has been implicated in many types of cancers including NPC. Herein, we characterized mRNA and miRNA transcriptomes by RNA sequencing (RNASeq) of NPC model systems. Matched total mRNA and small RNA of undifferentiated Epstein-Barr virus (EBV)-positive NPC xenograft X666 and its derived cell line C666, well-differentiated NPC cell line HK1, and the immortalized nasopharyngeal epithelial cell line NP460 have been sequenced by Solexa technology.

Genome-wide microRNA analysis of NPC and non-NPC specimens gene expression

Project description:Analysis of differential expression between NPC and non-NPC tissues at miRNA expression level. We used a miRNA microarray platform to investigate the profile between NPC tissues and normal nasopharyngeal tissues to evaluate the relationship between miRNA expression and NPC. Recognition of the aberrant miRNAs and enrichment pathway analysis of predicted target gene may provide some clues to estimate the mechanism of miRNA effects on NPC carcinogenesis mediated by miRNA-mRNA regulation. Total RNA was extracted from 8 NPC tissues compared to 4 nasopharyngeal tissues. We peformed the Illumina miRNA microarray to identify the differentially expressed miRNA between NPC tissues and normal nasopharyngeal tissues.

Comparing Control and Schizophrenic hiPSC-derived NPCs

Project description:Cell-based models of many neurological and psychiatric diseases, established by reprogramming patient somatic cells into human induced pluripotent stem cells (hiPSCs), have now been reported. While numerous reports have demonstrated that neuronal cells differentiated from hiPSCs are electrophysiologically active mature neurons, the “age” of these cells relative to cells in the human brain remains unresolved. Comparisons of gene expression profiles of hiPSC-derived neural progenitor cells (NPCs) and neurons to the Allen BrainSpan Atlas indicate that hiPSC neural cells most resemble first trimester neural tissue. Consequently, we posit that hiPSC-derived neural cells may most accurately be used to model the early developmental defects that contribute to disease predisposition rather than the late features of the disease. Though the characteristic symptoms of schizophrenia (SCZD) generally appear late in adolescence, it is now thought to be a neurodevelopmental condition, often predated by a prodromal period that can appear in early childhood. Postmortem studies of SCZD brain tissue typically describe defects in mature neurons, such as reduced neuronal size and spine density in the prefrontal cortex and hippocampus, but abnormalities of neuronal organization, particularly in the cortex, have also been reported. We postulated that defects in cortical organization in SCZD might result from abnormal migration of neural cells. To test this hypothesis, we directly reprogrammed fibroblasts from SCZD patients into hiPSCs and subsequently differentiated these disorder-specific hiPSCs into NPCs. SCZD hiPSC differentiated into forebrain NPCs have altered expression of a number of cellular adhesion genes, reduced WNT signaling and aberrant cellular migration. 3 independent differentiations (biological replicates) for each of four control and four schizophrenic patients were analyzed.

Human nasopharyngeal carcinoma

Project description:To uncover the oncogenic pathways of nasopharyngeal carcinoma, gene expression profiles of primary NPC cell strains and NPC-derived cell lines were conducted and analyzed in depth. Keywords: Oncogenesis Gene expression profiles of 9 primary NPC cell strains and 5 NPC-derived cell lines were analyzed. Forty Î¼g total RNA from one NPC sample was needed for a dye-swap experiment. Total RNA from 32 normal nasopharyngeal epithelial cell strains was pooled to serve as a universal reference.
