Transcription profiling of Arabidopsis albino mutant DS 13-2198-1

ABSTRACT: The effect Ds insertion mutation in Ds13-2198-1 line on the gene expression profiles was investigated. The genes for photosynthesis and some transcriptional factors were upregulated while genes for metabolism were downregulated. Experiment Overall Design: To investigate the effect of an strong albino mutation, the genome wide gene expression profiles of plants were examined. Segregants with normal phenotype and albino phenotype obtained from the heterotalic parental line were grown on the same 1/2 MS plate for 3 weeks.

Elucidating the function of each gene in a genome is important for understanding the whole organism. We previously constructed 4000 disruptant mutants of Arabidopsis by insertion of Ds transposons. Here, we describe a top-down phenomics approach based on metabolic profiling that uses one-dimensional 1H and two-dimensional 1H,13C NMR analyses and transcriptome analysis of albino mutant lines of Arabidopsis. One-dimensional 1H NMR metabolic fingerprinting revealed global metabolic changes in the a ...[more]

Transcription profiling of Arabidopsis ahg1 and ahg3 mutants

Project description:The effect of ahg1 and ahg3 on the gene expression profiles is similar but some genes are differentially affected. Experiment Overall Design: To investigate the effect of ahg1 and ahg3 mutations, the genome wide gene expression profiles of germinating seedlings were examined. These mutations occurred in close but distinct PP2C genes. Stratified seeds were transferred to plates containing 0.5 uM ABA and allowed germinate at 23 Â°C under 16hr light 8hr dark conditions. After two days samples were collected for RNA extraction.

Nystagmus in the B6(CG)Tyr(c-2J)/J Albino Mouse: A Functional and RNAseq Analysis

Project description:PURPOSE: Infantile nystagmus syndrome (INS) is a gaze-holding disorder characterized by conjugate, uncontrolled eye oscillations that can result in significant visual acuity loss. INS is often associated with albinism, but the mechanism is unclear. Albino mice have nystagmus; however, a pigmented mouse with a tyr mutation making it phenotypically albino, the B6(CG)-Tyr(c-2J)/J (B6 albino), had not been tested. We tested optokinetic nystagmus reflexes (OKN) in B6 albino and control mice. RNA-Seq was performed on extraocular muscles (EOM), tibialis anterior muscle (TA), abducens (CN6), and oculomotor (CN3) neurons to uncover molecular differences that could account for nystagmus.

Transcription profiling of human parathyroid tumour compared to its adjacent normal tissue in a case of primary hyperparathyroidism and undetectable serum PTH due to a truncating PTH gene mutation

Project description:A investigation of the gene expression of one parathyroid tumour compared to its adjacent normal tissue Experiment Overall Design: Affymetrix Human Gene Expression Chip (Human Genome U133 plus 2.0 Array.

Transcript profiling of Arabidopsis albino msh1 mutants

Project description:The soybean msh1 RNAi transgenic line show various growth phenotype. We use microarray analysis to characterize gene expression pattern for two of the phenotypes - variegation and stunted growth. Wild type and Arabidopsis msh1 mutant albino tissues were collected for RNA extration and hybridization on Affymetrix.

Transcription profiling of Arabidopsis thaliana rosettes IN an extended night

Project description:Usually starch is nearly depleted at the end of the night. To induce a gradual depletion of carbon, we have analysed the global response of transcripts during an extension of the night, where carbon becomes severely limiting from about four hours onwards. Experiment Overall Design: Arabidopsis thaliana rosettes were harvested in successive timpoints in an extended night situation.

Transcription profiling of mouse C2C12 myoblast induced with tetracycline to enhance integrin alpha7 expression

Project description:Analysis of C2C12 myoblast induced with tetracycline to enhance integrin alpha7 expression. Integrin alpha7 is the major laminin binding integrin in muscle cells. Enhancing its expression has been demonstrated to alleviate pathology in a murine model of Duchenne muscular dystrophy. Results of this study provide insights into the effects of increasing integirn alpha7 expression on muscle cells and possible side effects associate with enhancing integrin alpha7 in muscle cells. Experiment Overall Design: Triplicate biological smaples for each condition(induced and non-induced) C2C12 myoblast were used.

Comparative genomic hybridization proling of human Ewing Sarcoma tumour samples (26)

Project description:Ewingâs Sarcoma (ES) is characterized by specific chromosomal translocations, the most common being t(11;22)(q24;q12). Additionally, other types of genetic abnormalities may occur and be relevant to explain the variable tumoural biology and clinical outcome. We have carried out a high-resolution array CGH and expression profiling on 25 ES tumour samples to characterize the DNA copy number aberrations (CNA) occurring in these tumours and to determine their association with gene expression profiles (GEO Series accession number: GSE8303) and their clinical outcome. CNA were observed in 84% of the cases. We observed a median number of 3 aberrations per case. Besides numerical chromosomal changes, smaller aberrations were found and defined at chromosomes 5p, 7q and 9p. All CNA were compiled to define the smallest overlapping regions of imbalance (SORI). Thirty five SORI were delimited. Bioinformatic analyses were conducted to identify subgroups according to the pattern of genomic instability obtained. Unsupervised and supervised clustering analyses (using SORI as variables) segregated the tumours into two distinct groups: one genomically stable (â¤ 3 CNA) and another genomically unstable one (> 3 CNA). The genomic unstable group showed a statistically significant shorter overall survival and was more refractory to chemotherapy. This report elucidates data about genomic instability in ES, based on CNA and expression profiling for the first time, and shows that a genomically unstable group of Ewing tumours is correlated with a significant poor prognosis. Experiment Overall Design: Comparative experiment: pheripheral blood pool of ten healthy female donors: CONTROL vs. 26 Ewing Sarcoma Tumour Samples. Experiment Overall Design: Note that although 26 samples were profiled, only 25 were analysed (sample #11 did not pass quality control).
