Comparison of cross-species and species-specific hybridizations

Project description:Abstract Background: One of the approaches for conducting genomics research in organisms that do not yet have a proper microarray template is to profile their expression patterns by using cross-species hybridization (CSH). Several different studies using spotted microarray for CSH resulted with contradicting conclusions as to the ability of CSH to reflect biological processes. Results: We used a tomato spotted cDNA microarray to examine the ability of CSH to reflect species specific hybridization (SSH) data. Potato RNA was hybridized to spotted cDNA tomato and potato microarrays to generate heterologous and homologous hybridization data, respectively. The results revealed difficulties in obtaining transcriptomics data from CSH that reflected those obtained from SSH. Nevertheless, once the data was filtered for those corresponding to matching probe sets, by restricting proper cutoffs of probe homology, the CSH transcriptomics data better reflected those of the SSH, to an extent that was quantitated by identification of differentially regulated genes. Conclusions: This study enabled us to outline some considerations regarding evaluation of a microarray as candidate platform for CSH study, performance of CSH and proper data analysis that may allow CSH to reflect to some extent a biological process. Keywords: cross-species hybridization; heterologous hybridization

Cross-Species Comparison Identifies Proneural specific patterns of genetic alterations in Glioblastoma

Project description:The determinants of the genetic complexity of Glioblastoma are poorly understood. We generated murine Glioblastomas by transforming glial progenitors in the adult brain with PDGF expression and PTEN deletion +/- p53 deletion. PDGF+PTEN-/- tumors developed additional deletions of specific genes in up to 100% of the tumors, whereas PDGF+PTEN-/-p53-/- tumors did not. Cross-species comparison with data from tCGA database and published in Verhaak, 2010, showed that consistent genetic deletions observed in mouse tumors were specific to human Proneural Glioblastoma. These findings show that the genetic alterations that accumulate during tumor progression are determined by the initiating genetic alterations and by the cellular context in which they occur. Murine gliomas were induced in vivo by retroviral mediated PDGF overexpression, PTEN deletion with or without p53 deletion using Cre/lox system. Tumors were subsequently harvested for sequencing and aCGH analysis. Paired liver DNA was used for hybridization. For PDGF+PTEN-/- tumors, different timepoints were obtained including 21, 35 days post tumor induction, as well as endstage tumors.

Cross-species Detection in Barley1 GeneChip Array

Project description:This study was conducted to evaluate the efficiency of cross-species detection in Barley1 GeneChip array. We hybridized cRNA derived from first leaves of barley green seedlings (as a control), as well as the same stage of seedling leaf from representative genotypes of wheat, oat, rice, maize, and sorghum. Ten to twenty seedlings for each species were harvested and pooled for RNA preparation, labeling, and hybridization. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Rico Caldo.

Comparison of D. simulans/D. sechellia F1 male hybrid custom expression values to pure-species parents

Project description:Species often produce sterile hybrids early in their evolutionary divergence, and some evidence suggests that hybrid sterility may be associated with deviations or disruptions in gene expression. In support of this idea, many studies have shown that a high proportion of male-biased genes are underexpressed compared to non-sex-biased genes in sterile F1 male hybrids of Drosophila species. In this study, we examined and compared patterns of misexpression in 4 day old sterile male F1 hybrids of Drosophila simulans and its sibling species, D. sechellia. We analyzed hybrids using custom cDNA arrays we developed from RT-PCRs of spermatogenesis-related transcripts from these species and another sibling species (D. mauritiana). The results from a commercial genome-wide array for this species pair, from the custom chip and the genome-wide chip for the D. simulans-D. mauritiana species pair, and from the larvae of these two species pairs using the custom chip, is presented separately. Keywords: Comparison of pure-species Drosophila expression to hybrid expression
