Project description:Investigation of DNA methlation changing in thymidine treatment-induced MEFs. Mouse embryonic fibroblasts (MEFs) were obtained at E14.5 embryos and supplied with Dulbecco’s modified Eagle’s medium (DMEM) (Invitrogen) with 15% FBS, 100 μg/ml streptomycin and 100 U/ml penicillin. Potential hematopoietic progenitor cells (CD45+CD41+CD31+c-Kit+) were negatively selected with Biotin labeled anti-CD45, anti-CD31, anti-CD41 and anti-c-Kit antibodies by magnetic beads. Hereafter, treated MEFs are referred to as 4neg MEFs for initiation of induction. 4neg MEFs were seeded on mitomycin (MMC)-treated MEFs as feeder cells and cultured in DMEM with 15% FBS, 100 μg/ml streptomycin, 100 U/ml penicillin, 2 mM L-glutamine, 0.1 mM non-essential amino acids and 100 μM thymidine as induction medium for 2 days followed with analysis

Cells were then trypsinized and re-seeded to new feeder cells for another 6 days. Cells were positively selected with Biotin labeled anti-CD45 by magnetic beads followed with analysis.
Project description:cGMP is well-known secound messanger involved in vascular homeostasis. However little is known the effect of cGMP inducer on mRNA expression in cancer cells. We performed microarrays to revealed the transcriptional change of a human pancreatic ductal adenocarcinoma (PDCA) cell line (Panc -1) to cGMP inducer Bay41-2272 in order to provide insight into impact of cGMP induction on Panc-1 cells. Panc-1 Human PDCA cells were treated with vehicle (DMSO) or 5 μM Bay41-2272 for 48 h and total RNA was extracted by using TRIzol Reagent. The microarray analysis was conducted on the Panc-1 cells expressing by using Agilent Microarray.
Project description:Analysis of differentially expressing genes in whole genome wide analysis of ALPPL2 expressing Panc-1 cells (Panc-1+ve) via siRNA mediated knockdown of ALPPL2 Panc-1 +ve and Panc-1-ve cell lines were generated from Panc-1 cell line based upon its hetergenous binding to aptamer SQ2. Detailed procedure of generation of these cell lines are described in Pooja Dua, Hye Suk Kang, Seung-Mo Hong, Ming-Sound Tsao, Soyoun Kim, and Dong-ki Lee. 2012 Alkaline Phosphatase ALPPL2 is a novel pancreatic carcinoma-associated protein. Cancer Research A four chip study using total RNA recovered from Panc-1+ve cells transfected with siALPPL2-2, siALPPL2-3, siGFP control and Lipofectamine 2000 treatament . Each chip measures 45,033 genes with three 60 mer probe pairs per target.
Project description:In this study we analyzed the proteomic profiles of H460, and MCF7 3D tumor spheroids grown either in standard medium (3D_SM), or in FBSlow conditions (3D_FBSlow) and compared them to their relative 2D cultures (2D). Standard medium consisted of DMEM/F-12 supplemented with 0.5% Glucose, 2.5mM L-Glutamine, 2% B-27, 5μg/ml Heparin, 20μg/ml Insulin, 20ng/ml EGF, 20ng/ml Recombinant Human bFGF, 0.1% Bovine Serum Albumin (BSA) and 1% (v/v) of penicillin/streptomycin 100U/ml. FBSlow medium consisted of customized nutrient-restricted RPMI or DMEM culture media supplemented with only 2% FBS.

Project description:The Panc-1 human pancreatic cancer line (ATCC) was constructed to stably express control or GSK3B shRNA. Control or GSK3B shRNA expressing Panc-1 cells were implanted subcutaneously into the flanks of 3-5 week old, female, athymic nude mice. Tumors were grown to at least 250mm3. Tumor tissue was microdissected for further analysis. We compared control shRNA (n=4) to GSK3B shRNA (n=3) Panc-1 xenografts. The array data with simple statistical calculations are also provided in a supplementary Excel workbook, with probe-set annotation that we used at the time (users may want newer annotation). We compared xenografts of Panc-1 (Human pancreatic carcinoma cell line, grown in mice) stably expressing GSK3B shRNA (n=3) to similar xenografts with control shRNA (n=4). Xenografts were grown in the flanks of female, athymic nude mice until they reached at least 250mm3. Tumor tissue was microdissected for further analysis. mRNA abundance assays were performed using Affymetrix HG_U133_plus_2 arrays, with 54675 probe-sets.
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.
