Transcription profiling of human Ishikawa cells treated with Bisphenol A

ABSTRACT: This study provides a comprehensive evaluation of changes in gene expression during treatment with Bisphenol A in vitro. Ishikawa cells were maintained and grown (to confluency or at a desired cell density between 500,000 - 1 million cells/mL) in DMEM/F-12 Medium (supplemented with 10% Fetal Bovine Serum + 1X penicillin/streptomycin) in xenoestrogen-free Corning plasticware. Cells were gently washed in warm PBS and transferred to phenol red-free DMEM/F-12 Medium (supplemented with 10% Charcoal-Stripped Fetal Bovine Serum + 1X penicillin/streptomycin) in Corning Cell Culture Cluster wells overnight and then challenged with 1pM (very low, vL), 100pM (low, L), 10nM (high, H), and 1uM (very high, vH) levels of BPA. Prior to collection, cells were washed in warm PBS, resuspended & briefly incubated in TRI-Reagent, & finally collected (in quintuplicate replicates) at each specific time point: 8 hours, 24 hours, and 48 hours. Following RNA isolation, the best RNA yields for each quadruplicate set was selected for target preparation and GeneChip processing. Experiment Overall Design: 60 total samples: 5 Doses [Vehicle Control, Very Low (1 pM), Low (100 pM), High (10 nM), Very High (1 uM)]; 3 Timepoints [8 hour, 24 hour, 48 hour]; 4 Replicates each.

Effects of environmental chemicals on development of neuronal cell lineages derived from mouse ES cells

Project description:This study provides a comprehensive evaluation of changes in gene expression during treatment with environmental chemicals in embryonic bodies derived from mouse embryonic stem (ES) cells. ES cells were maintained under the feeder cells in phenol red-free DMEM Medium (supplemented with 15% FBS, 100uM Non-essential amino acids (NEAA), 1000U/ml Leukemia inhibitory factor(LIF), 100uM 2-mercaptoethanol(2-ME), and 0.5% penicillin/streptomycin). Cells were gently washed in warm PBS and transferred to phenol red-free DMEM Medium (supplemented with 15% KnockOut Serum Replacement, 100uM NEAA, 100uM 2-ME, and 0.5% penicillin/streptomycin) in Microsphere array (MSA300F) and exposed with low and high levels of each chemical just after removing LIF from the culture media. Prior to collection, cells were washed in warm PBS, resuspended and briefly incubated in the QIAGEN RLT buffer, and finally collected in triplicate at 48 hours. Following RNA isolation, the best RNA yields for each replicate set was selected for target preparation and microarray processing.

Multifactorial remodeling of the cancer immunopeptidome by interferon gamma

Project description:In this study we combined previous transcriptomics and immunopeptidomics data with new proteomics data from untreated and IFNg-treated CRC PDOs to dissect mechanisms that lead to remodeling of the immunopeptidome through IFNg treatment (this is from the paper introduction, let me know if it needs any stylistic changes). · Experiment description: The cells were grown in DMEM/F12 media with 20% fetal bovine serum, 1X Glutamax, 100 units/ml penicillin/streptomycin and 2% matrigel, and treated with 600ng/mL IFNg for 48 hours before harvesting. Cells were washed twice with ice-cold PBS then snap-frozen.

Characterization of the microbial community structure in Candidatus Liberibacter asiaticus-infected Citrus plants treated with antibiotics in the field

Project description:Huanglongbing (HLB) is a worldwide devastating disease of citrus. There are no effective control measures for this newly emerging but century-old disease. Previously, we reported a combination of Penicillin G and Streptomycin was effective in eliminating or suppressing the associated bacterium, ‘Candidatus Liberibacter asiaticus’ (Las). Here we report the bacterial composition and community structure in HLB-affected citrus plants during a growing season and while being treated with antibiotic combinations PS (Penicillin G and Streptomycin) and KO (Kasugamycin and Oxytetracycline) using the Phylochip™ G3 array.

RNA-seq analysis of A3250 inflammatory breast cancer (IBC) xenografts and cells in vitro

Project description:Purpose: Transcriptome profiling (RNA-seq) of a novel human Inflammatory Breast Cancer cell line A3250 and its xenograft tumors Methods: A3250 tumor cells were maintained as adherent cultures in standard tissue culture dishes, in high-glucose DMEM supplemented with 4 mM L-glutamine, 10% FBS, and 1X antibiotics (100 U/ml penicillin, 100 U/ml streptomycin) Tumor cells cultured in vitro were harvested for RNA-Seq analysis at 80% confluency. To generate tumors, A3250 tumor cells (1 x 10E6 cells in 100 µl PBS) were injected into the fourth mammary fat pads of eight to nine-week-old SCID mice. Tumors were harvested at 5-6 weeks post-injection, when they reached 4-5 mm in diameter. Results: A3250 is a novel IBC cell line that recapitulates key features of human IBC in a mouse xenotransplant. RNA-Seq analysis identified expression profile characteristic for this cell line and its tumors.

DNA methylation array of irradiated and/or lithium exposed iPSC-derived human neural progenitor cells

Project description:DNA isolation was performed following the DNeasy Blood and Tissue Kit (Qiagen). Cells were irradiated in an CIX2 Xstrahl X-Ray Irradiator with Aluminum filter at a focus-to-skin distance (FSD) of 40 cm and with an energy of 195kV, 10 mA, for and absorbed dose of 4 GY. To allow for assessment of irradiation damage, cells remained in the incubator for 1 hour. Pre-warmed DMEM/F-12 was mixed with the appropriate amount of LiCl powder (Sigma-Aldrich, Cat# L9650-100G), passed through a 0.22 μm filter, and supplemented with 1% Penicillin-Streptomycin, 1% N2, 0.1% B27, 0.1% EGF, and 0.1% FGF2 to produce 3mM Lithium Chloride (LiCl) hNSPC medium.
