Transcription profiling by array of human DA-MB-231 breast cancer cells treated with various SCFA-hexosamine analogs

Project description:The purpose of this study was to characterize the gene expression profile of MDA-MB-231 breast cancer cells treated with various SCFA-hexosamine analogs to better understand the role of various modifications to this scaffold. Experiment Overall Design: In total, six analogs were investigated in this study. For the relatively ""toxic"" C6-SCFA analogs, IC30 was selected to explore initial growth inhibitory and apoptotic gene expression changes. Two independent biological replicates were analyzed for each analog-treated condition. Three independent biological replicates were analyzed for the vehicle-treated control (EtOH).

Glyco-gene expression in human breast cancer MDA-MB-231 cells treated with ManNAc analogs

Project description:Analogs of ManNAc, the committed precursor of sialic acid, decrease metastatic potential and trigger apoptosis in cancer cells. Adding Lev to ManNAc analogs increases their toxicity due to an ill-understood mechanism. Comparing gene expression profiles of cells treated with Ac4ManNLev and Ac4ManNAc will provide insight into the similarities and differences of these analogs. Specifically, MDA-MB-231 human breast cancer cells will be treated with Ac4ManNLev and Ac4ManNAc at doses that inhibit cell growth and induce the cell to undergo apoptosis later. RNA will be harvested in the early stage of cell arrest in order to identify genes altered by Ac4ManNLev and Ac4ManNAc. RNA preparations from three conditions, were sent to Microarray Core (E). One as control (Ethanol), and two experimental groups: high concentration Ac4ManNAc (100 uM) and high concentration Ac4ManNLev (100 uM). The aim is to gain insight into apoptosis and cell cycle arrest. Specifically, the Ac4ManNLev samples will be comprared to a less potent ManNAc analog. The RNA was amplified, labeled, and hybridized to the GLYCOv3 microarrays.

Murine host body reactions to implanted scaffolds: non-coat polystyrene scaffold vs. collagen- or PMB-coated scaffold

Project description:This study investigated early host reactions to implanted materials to predict successful tissue regeneration with implant. Three kinds of scaffold, i.e., non-coat, collagen-coated, and PMB-coated porous polystylene scaffolds were implanted subcutaneously in mice dorsal area. Those scaffolds were used as bio-incomopatible materials, appropriate materials for tissue regeneration (bio active), and inappropriate to regenration (bio-inert) scaffolds. Seven days after implantation, scaffolds were explanted and total RNA was isolated from infiltrated host cells into scaffold by laser microdissection. Gene expressions of cells in collagen- and PMB-coated scaffold were normalized using results of non coat scaffold. Genes with more than 2-fold difference between collagen and PMB were picked up and narrowed to related keywords; inflammation, angiogenesis, wound healing, and mcrophage polarization. Among those genes, interluekin (IL)-1beta which promote both inflammation and wound healing was up-regulated in collagen-coated scaffold. On the other hand, IL-10 which suppress both inflammation and wound healing was up-regulated in PMB-coated scaffold. Angiogenesis-promoting genes were up-regulated and angiogenesis suppressve genes were suppressed in collagen. Up-regulation of IL-1b and the angiogenesis-relating genes inside the porous scaffolds are the possibly important factors for controlling tissue regeneration. Three-condition experiment, host cells infiltrated in non coat (reference), collagen-coated, and PMB-coated scaffolds. Two-microarray condition experiments, collagen vs. non coat and PMB coat vs. non coat. Hybridization: 2 replicates. Scanning: 3 replicates. Biological experiments: once.
