Although the first mouse embryonic stem (ES) cell lines were derived 25 years ago using feeder-layer-based blastocyst cultures, subsequent efforts to extend the approach to other mammals, including both laboratory and domestic species, have been relatively unsuccessful. The most notable exceptions were the derivation of non-human primate ES cell lines followed shortly thereafter by their derivation of human ES cells. Despite the apparent common origin and the similar pluripotency of mouse and hu ...[more]

Extensive proteomic approaches to identify glycosylphosphatidylinositol-anchored proteins in Arabidopsis reveal their diverse responses to cold acclimation

Project description:When plants are exposed to non-freezing low temperatures, they can increase their freezing tolerance (cold acclimation, CA). Changes of plasma membrane (PM) and sterol/sphingolipid-enriched microdomain proteins are thought to be crucial for acquisition of freezing tolerance. Particularly, glycosylphosphatidylinositol-anchored proteins (GPI-APs), which are lipid-modified proteins and potentially targeted to PM surface and apoplast, are deeply-involved in microdomain functions. However, GPI-AP functions in the CA mechanisms are not yet characterized. In present study, we conducted large-scale proteomics to investigate CA-induced GPI-APs in Arabidopsis leaves.

Expression data from mammary gland during pregnancy and lactation of CBA/CaH, QSi5 and Advanced Intercross Line (AIL; CBA/CaH X QSi5, the 14th generation)

Project description:Previously we have shown significant differences in lactation performance, mammary gland histology and expression profiles of mammary transcriptome during peak-lactation (lactation day 9; L9) between the ordinary CBA/CaH (CBA) and the superior QSi5 strains of mice. In the present study, we compared mammary gland histology between CBA and QSi5 at mid-pregnancy (pregnancy day 12; P12). We assessed lactation performance during the first 8 days of lactation of the 13th - 14th generation of the Advanced Intercross Line (AIL) (CBA X QSi5) mice. We utilized an integrative approach to analyzing mammary microarray expression profiles of CBA and QSi5 at P12 and CBA, AIL and QSi5 at L9. The inguinal mammary glands of CBA/CaH and QSi5 during mid-pregnancy (Pregnancy day 12; P12), and the glands of CBA/CaH, AIL and QSi5 during peak lactation (Lactation day 9; L9) were collected and total RNA was extracted for Affymetrix microarray (mouse genome 430 2) assay

Transcription profiling of mouse embryonic stem cells (ES cells) hree days upon LIF withdrawal (d3) compared to pluripotent cells and of genes whose expression is modulated at d3 under anti-apoptotic conditions (p38 inhibitor PD169316).

Project description:Mouse embryonic stem (ES) cells remain pluripotent in vitro when grown in presence of Leukaemia Inhibitory Factor (LIF). LIF starvation leads to apoptosis of some of the ES-derived differentiated cells, together with p38a MAP kinase activation. Apoptosis, but not morphological cell differentiation, is blocked by a p38 inhibitor, PD 169316. To further understand the mechanism of action of this compound, we have identified its specific targets by microarray studies. We report on the global expression profiles of genes expressed at three days upon LIF withdrawal (d3) compared to pluripotent cells and of genes whose expression is modulated at d3 under anti-apoptotic conditions. We showed that at d3 without LIF cells express, earlier than anticipated, specialized cell markers and that when the apoptotic process was impaired, expression of differentiation markers was altered. In addition, functional tests revealed properties of anti-apoptotic proteins not to alter cell pluripotency and a novel role for metallothionein 1 gene which prevents apoptosis of early differentiated cells.

Differential gene expression in Malaysian and Wine/European yeast isolates

Project description:Comparative-genomic studies have reported widespread variation in levels of gene expression within and between species. In the vast majority of cases, the phenotypic and evolutionary relevance of regulatory change is unknown. We haveu sed a wild Malaysian population of S. cerevisiae as a testbed in the search to identify organismal correlates of regulatory variation. Malaysian yeast, when cultured in standard medium, activated regulatory programs that protect cells from the toxic effects of high iron. Analysis of differential gene expression between three Malaysian and two Wine/European isolates and allele-specific expression within three Malaysian x Wine/European hybrids.

Replication-coupled passive DNA demethylation for the erasure of genome imprints in mice

Project description:Genome-wide DNA demethylation, including the erasure of genome imprints, in primordial germ cells (PGCs), is critical as a first step for creating the totipotent epigenome in the germ line. Here, we provide evidence that contrary to the prevailing model involving active DNA demethylation, imprint erasure in mouse PGCs occurs in a manner consistent with replication-coupled passive DNA demethylation: PGCs erase imprints during their rapid proliferation with little de novo as well as maintenance DNA methylation potential and no major chromatin alterations. Our findings necessitate the re-evaluation of and provide novel insights into the mechanism of genome-wide DNA demethylation in PGCs. We performed expression analysis of primordial germ cells (PGCs) at embryonic days 10.5-13.5. Because the number of PGCs available at these stages were low, cDNAs were amplified by the method that we previously published (Kurimoto et al. 2006, NAR 34: e42 (PMID 16547197)). To include analysis of PGC gene expression at E9.5, we re-normalized the data from our E9.5 PGC samples (GSM744103, GSM744104) from our previous publication (Hayashi et al., 2011, Cell 146: 519-32 (PMD 21820164)) together with the data from this submission.

Relationship of mammographic density and gene expression: analysis of normal breast tissue surrounding breast cancer

Project description:Purpose: Previous studies of breast tissue gene expression have demonstrated that the extratumoral microenvironment has substantial variability across individuals, some of which can be attributed to epidemiologic factors. To evaluate how mammographic density (MD) and breast tissue composition relate to extratumoral microenvironment gene expression, we used data on 121 breast cancer patients from the population-based Polish Women’s Breast Cancer Study.Design: Breast cancer cases were classified based on a previously reported, biologically-defined extratumoral gene expression signature with two subtypes: an Active subtype, which is associated with high expression of genes related to fibrosis and wound response, and an Inactive subtype, which has high expression of cellular adhesion genes. MD of the contralateral breast was assessed using pre-treatment mammograms and a quantitative, reliable computer-assisted thresholding method. Breast tissue composition was evaluated based on digital image analysis of tissue sections. Results:The Inactive extratumoral subtype was associated with significantly higher percentage mammographic density (PD) and dense area (DA) in univariate analysis (PD: p=0.001; DA: p=0.049) and in multivariable analyses adjusted for age and body mass index (PD: p=0.004; DA: p=0.049). Inactive/higher MD tissue was characterized by a significantly higher percentage of stroma and a significantly lower percentage of adipose tissue, with no significant change in epithelial content. Analysis of published gene expression signatures suggested that Inactive/higher MD tissue expressed increased estrogen response and decreased TGF-ß signaling. Conclusions:By linking novel molecular phenotypes with MD, our results indicate that MD reflects broad transcriptional changes, including changes in both epithelia- and stroma-derived signaling. reference x sample
