Transcription profiling twenty eight growth restricted patients (including twenty two with Silver-Russel syndrome) and their parents

ABSTRACT: We studied twenty-eight growth restricted patients (twenty-two with Silver-Russell syndrome, OMIM#180860) and their parents with the Affymetrix 250K Sty SNP microarray. All patients were molecularly undefined, and thus the aim was to look for copy number alterations that might contribute to the growth restriction. Aberrations found in parents were used to reduce the list of interesting variations to de novo variants.

<h4>Background</h4>Silver-Russell syndrome (SRS, OMIM 180860) features fetal and postnatal growth restriction and variable dysmorphisms. Genetic and epigenetic aberrations on chromosomes 7 and 11 are commonly found in SRS. However, a large fraction of SRS cases remain with unknown genetic aetiology.<h4>Methods</h4>22 patients with a diagnosis of SRS (10 with H19 hypomethylation and 12 of unknown molecular aetiology) and their parents were studied with the Affymetrix 250K Sty microarray. Several ...[more]

Non-allelic homologous recombination between retrotransposable elements is a major driver of de novo unbalanced translocations.

Project description:Large scale analysis of balanced chromosomal translocation breakpoints has shown nonhomologous end joining and microhomology-mediated repair to be the main drivers of interchromosomal structural aberrations. Breakpoint sequences of de novo unbalanced translocations have not yet been investigated systematically. We analyzed 12 de novo translocations and mapped the breakpoints in 9. Surprisingly, in contrast to balanced translocations, we identify non-allelic homologous recombination (NAHR) between (retro)transposable elements and especially long interspersed elements (LINEs) as the main mutational mechanism. This finding implicates (retro)transposons to be a major driver of genomic rearrangements and exposes a profoundly different mutational mechanism compared to balanced chromosomal translocations. Furthermore, we show the existence of compound maternal/paternal derivative chromosomes, reinforcing the hypothesis that human cleavage stage embryogenesis is a cradle of chromosomal rearrangements. In total 36 non-amplified genomic DNA samples (12 patients plus parents) extracted from blood or amniocytes were analyzed by 250K Nsp I SNP arrays (GEO accession number GPL3718).

Expression data wheat Flag Leaf at anthesis

Project description:TaMYB13 is a transcription factor that has been associated with fructan accumulation in previous studies in wheat (Xue et al. 2011 Plant journal 68: 857 - 870). In this study we aimed to find genes regulated by TaMYB13, through overexpression of this transcription factor in wheat and perform expression analysis by making use of Affymetrix genechip assays. Expression of control plants was compared to transgenic lines, and total RNA was extracted from Flag leaves at anthesis. In this experiment the genome wide gene expression was assessed from wheat flag leaf material harvested at anthesis. Control plants (BW43,BW44,BW45) were compared with transgenic lines that overexpress TaMYB13 (a20, b2, b36).

Genotypic differences in water soluble carbohydrate metabolism in Triticum aestivum leaves

Project description:Fructans represent the major component of water soluble carbohydrates (WSCs) in the maturing stem of temperate cereals and are an important temporary carbon reserve for grain filling. Theoretically, genotypic variation in carbon reserve accumulation is determined by relative carbon availability and demand at the whole plant level. To evaluate the importance of source carbon availability in fructan accumulation and its associated molecular mechanisms, we performed comparative analyses of individual WSC components and the expression profiles of genes involved in major carbohydrate metabolism and photosynthesis in flag leaves of recombinant inbred lines derived from a cross between wheat cultivars Seri M82 and Babax (SB lines). High sucrose levels in the mature flag leaf (source carbon organ) were found to be positively associated with WSC and fructan concentrations in both the leaf and stem of SB lines in several field trials. Analysis of Affymetrix expression array data revealed that high leaf sucrose lines grown in abiotic-stress-prone environments had high expression levels of a number of genes in the leaf involved in the sucrose synthetic pathway and photosynthesis, such as Calvin cycle genes, antioxidant genes involved in the removal of chloroplast H2O2 and genes involved in energy dissipation. The expression of the majority of genes involved in fructan and starch synthetic pathways were positively correlated with sucrose levels in the leaves of these SB lines. 8 genotypes of recombinant inbred lines Seri M82 x Babax with 2 biological replicates per genotype. Grown in the field under irrigated conditions.

Whole genome transcriptional analysis of Alzheimer's disease patients compared with age-matched non-demented controls

Project description:Alzheimer’s disease (AD) is an aging related neurodegenerative pathology that affects millions of people worldwide. This pathology has been related to a range of features such as deposition of proteins in the brain, alterations in cell cycle, accumulation of DNA damage, DNA repair deficiency and mitochondrial dysfunction, however the molecular mechanisms implicated in its pathogenesis are still uncertain. Thereby, the present study aimed to evaluate whether peripheral blood mononuclear cells (PBMCs) of AD patients display alterations in gene expression profilescompared to age-matched controls. Blood samples were collected from 25 AD patients and 15 age-matched controls in order to perform genome-wide mRNA expression (microarray). In blood cells, Rank products bioinformatics analysis indicated 593 mRNAs adifferentially expressed in AD compared to controls. Our results demonstrated that PBMCs have alterations in cell cycle and DNA repair as proposed for AD neurons, reinforcing the idea that AD blood cells can provide information about AD status and also can be import as source of studies to better understand the disease.

Root transcriptional profile of tomato Fe-deficient plants in response to supply with natural chelating agents.

Project description:Tomato, a Strategy I model plant for Fe deficiency, is an important economical crop. The transcriptional responses induced by Fe deficiency in tomato roots were previously described (Zamboni et al., 2012). The changes in trascriptome caused by the supply of Fe to plants starved fro 1 week were described in relation to the different nature of chelating agents (Fe-WEHS, Fe-CITRATE and Fe-PS). Transcriptional profile obtained by roots (27-d) of 21-d-old tomato plants starved of iron (0 Î¼M Fe-EDTA) for 1 week and supplied for 1 h with 1 Î¼M of Fe as Fe-WEHS (supply_Fe_WEHS), Fe citrate (supply_Fe_CITRATE) and Fe-PS (supply_Fe_PS). Tomato plants were hydroponically grown in all three case of Fe supply. Three different biological replicates were used for each sample repeating the experiment three times. All samples were obtained pooling roots of six plants (27-d-old).
