Replicative senescence in post-selection HMECs

ABSTRACT: Transcriptional abundance in each of senescent populations from two post-selection HMEC lines (48R and 184) is compared with abundance in isogenic early passage proliferating cells and also with abundance in early passage quiescent cells. A strain or line experiment design type assays differences between multiple strains, cultivars, serovars, isolates, lines from organisms of a single species. Keywords: strain_or_line_design

Androgen receptor coregulators baseline comparisons

Project description:LNCaP cells are an established androgen receptor expressing prostate carcinoma cell line. Human foreskin fibroblasts also expressing the androgen receptor were obtained from phenotypic normal male individuals. Cells were cultured either at confluency leading to G0 cell cycle state or while they were proliferating. Cells were either untreated, or treated with dihydrotestosterone (DHT) or ethanol (ETOH) which also served as the solvent for the DHT. All experimental RNA samples derived from the untreated or treated cell lines were hybridized on cDNA arrays against a common reference. This reference was composed out of common reference CRG (50%) and out of fibroblast RNA (50%). This reference is also called "mixed reference" in the description of the 26 individual experiments. A strain or line experiment design type assays differences between multiple strains, cultivars, serovars, isolates, lines from organisms of a single species. Compound Based Treatment: dihydrotestosterone (DHT) or ethanol (ETOH = solvent) Cell Line: genital fibroblast cell line or prostate carcinoma cell line (LNCaP) Culture Synchrony: Go or proliferation Keywords: strain_or_line_design

Saccharomyces pastorianus strains comparison

Project description:Saccharomyces pastorianus is the yeast used to make lager beer; it is known to be an interspecific hybrid formed by the fusion between S. cerevisiae and S. bayanus genomes. This data set queries 17 S. pastorianus strains, collected at various times over the last 125 years from various breweries located in different geographical locations, which were obtained from CBS and DBVPG culture collections. The data in this set represent array-CGH experiments performed with these strains, using "2-species" custom Agilent arrays (the "2-species" arrays contain probes spaced every ~2 kb across the whole genomes of both S. cerevisiae and S. bayanus; the probes are unique and specific for each genome). The data set also contains 3 self-self hybridizations (S. cerevisiae + S. bayanus DNA mixed together in equimolar amounts, then labeled green or red in separate reactions, then hybridized to the "2-species" arrays) used for normalization in CGH-Miner analysis. A strain or line experiment design type assays differences between multiple strains, cultivars, serovars, isolates, lines from organisms of a single species. Keywords: strain_or_line_design

Affinity purification of ribosomes and associated RNAs using tagged Rpl16a and Rpl16b

Project description:In this study, we systematically identified RNAs associated with ribosomes. To identify ribosome associated RNAs, C-terminal ZZ-tagged Rpl16a or Rpl16b, expressed under control of thier native promoter, were affinity purified from whole cell extracts of cultures grown to mid-log phase in minimal medium. Extracts were incubated with immunoglobulin G (IgG) coupled microbeads, washed, and ribosomes were eluted by tobacco etch virus (TEV) protease treatment. We performed two biological replicates with each protein and analyzed the RNA content using oligo microarrays. Total RNA isolated from extracts of cells expressing Rpl16a-ZZ or Rpl16b-ZZ (input) and from the affinity-purified ribosomes was reverse transcribed with oligo(dT) primers. cDNA was labeled with Cy3 and Cy5 fluorescent dyes, respectively, and competitively hybridized to yeast oligo microarrays. Alternatively, RNA was isolated from sucrose gradient fractions containing 60S subunits, 80S monosomes and polysomes. Here, we performed four biological replicates. Analysis was done with oligo microarrays as described above. A strain or line experiment design type assays differences between multiple strains, cultivars, serovars, isolates, lines from organisms of a single species. strain_or_line_design

Role of CSN5 in breast cancer (array CGH)

Project description:CSN5 has been implicated as a candidate oncogene in human breast cancers by genetic linkage with activation of the poor-prognosis, wound response gene expression signature. CSN5 is a subunit of the eight-protein COP9 signalosome, a signaling complex with multiple biochemical activities; the mechanism of CSN5 action in cancer development remains poorly understood. Here we show that CSN5 isopeptidase activity is essential for breast epithelial transformation and progression. Amplification of CSN5 is required for transformation of primary human breast epithelial cells by defined oncogenes. The transforming effects of CSN5 require CSN subunits for assembly of the full COP9 signalosome and the isopeptidase activity of CSN5, which potentiates the transcriptional activity of MYC. Transgenic inhibition of CSN5 isopeptidase activity blocks breast cancer progression evoked by MYC and RAS in vivo. These results highlight CSN5 isopeptidase activity in breast cancer progression, suggesting it as a therapeutic target in aggressive human breast cancers. A strain or line experiment design type assays differences between multiple strains, cultivars, serovars, isolates, lines from organisms of a single species. Keywords: strain_or_line_design

Transcriptome study of human mammary epithelial cells following exposure to polymeric Eudragit RS nanoparticles part 1

Project description:To further study the transcriptome of human mammary epithelial cells (HMEC 184) after exposure to polymeric Eudragit RS nanoparticles (ENP), we investigate whole genome microarray expression to identify genes regulated by exposure or not to ENP. Changes in gene expression in HMEC 184 cells (50M-BM- % confluence) incubated with 25M-BM- M-BM-5g/mL ENPs (70M-BM- nm) for 24M-BM- h, and without incubation (control) were measured. Three biological replicates were performed as controls (US_01; US_02; US_04) and ENP exposed ones (US_6; US_07; US_08).
