Transcription profiling time series of the growth of human IMR-90 cells seeded on a collagen/chondroitin sulfate tissue engineering scaffold

ABSTRACT: A series of chips with some repeated measurments. Each chip represents a pool of 4 collagen/chondroitin sulfate tissue engineering scaffold meshes seeded with 1 x 10^6 IMR-90 Human Fibroblasts. mRNA was isolated at 30 minutes, 1, 2, 4, 8, 12, 24, 48, and 72 hours after seeding.

Global gene expression of cells attached to a tissue engineering scaffold.

Klapperich Catherine M CM Bertozzi Carolyn R CR

Biomaterials 20041101 25

A goal of tissue engineering is to produce a scaffold material that will guide cells to differentiate and regenerate functional replacement tissue at the site of injury. Little is known about how cells respond on a molecular level to tissue engineering scaffold materials. In this work we used oligonucleotide microarrays to interrogate gene expression profiles associated with cell-biomaterial interactions. We seeded collagen-glycosaminoglycan meshes, a widely used tissue engineering scaffold mate ...[more]

Temporal Quantitative Proteomic Profiling of SH-SY5Y and IMR-32 Neuroblastoma Cells During All-trans Retinoic Acid-Induced Neuronal Differentiation

Project description:The human neuroblastoma cell lines SH-SY5Y and IMR-32 can be differentiated into neuron-like phenotypes through treatment with all-trans retinoic acid (ATRA). After differentiation, these cell lines are extensively utilized as in vitro models to study various aspects of neuronal cell biology. However, temporal and quantitative profiling of the proteome and phosphoproteome of SH-SY5Y and IMR-32 cells throughout ATRA-induced differentiation has been limited. Here, we performed relative quantification of the proteomes of SH-SY5Y and IMR-32 cells at multiple time points during ATRA-induced differentiation. The data presented serve as a valuable resource for investigating temporal protein and phosphoprotein abundance changes in SH-SY5Y and IMR-32 cells during ATRA-induced differentiation.

Transcription profiling of human neuroblastoma cell line IMR-32 overexpressiong SQSTM1 and DPP3 to identify activators for the antioxidant response element

Project description:The antioxidant response element (ARE) is a cis-acting regulatory enhancer element found in the 5 flanking region of many phase II detoxification enzymes. Upregulation of ARE-dependent target genes is known to have neuroprotective effects; yet, the mechanism of activation is largely unknown. By screening an arrayed collection of approximately 15,000 full-length expression cDNAs in the human neuroblastoma cell line IMR-32 with an ARE-luciferase reporter, we have identified several cDNAs not previously associated with ARE activation. A subset of cDNAs, including sequestosome 1 (SQSTM1) and dipeptidylpeptidase III (DPP3), activated the ARE in primary mouse-derived cortical neurons. Overexpression of SQSTM1 and DPP3 in IMR-32 cells stimulated NRF2 nuclear translocation and led to increased levels of NAD(P)H:quinone oxidoreductase 1 (NQO1), a protein which is transcriptionally regulated by the ARE. When transfected into IMR-32 neuroblastoma cells that were depleted of transcription factor NRF2 by RNA interference, SQSTM1 and DPP3 were unable to activate the ARE or induce NQO1 expression, indicating that the ARE activation upon ectopic expression of these cDNAs is mediated by NRF2. Studies with pharmacological inhibitors indicated that 1-phosphatidylinositol 3-kinase (PI3K) and protein kinase C (PKC) signaling are also essential for activity. Lastly, overexpression of these cDNAs conferred partial resistance to hydrogen peroxide induced toxicity, consistent with the induction of antioxidant and phase II detoxification enzymes which can protect from oxidative stress. This work and other such studies may provide mechanisms for activating the ARE in the absence of general oxidative stress, and a novel therapeutic approach to degenerative diseases and aging. Samples were taken from duplicate transfections of different antioxidant response element activators

Transcription profiling of human fibroblasts grown in petri dishes vs. attached to a tissue engineering scaffold sampled at 7 timepoints.

Project description:A goal of tissue engineering is to produce a scaffold material that will guide cells to differentiate and regenerate functional replacement tissue at the site of injury. Little is known about how cells respond on a molecular level to tissue engineering scaffold materials. In this work we used oligonucleotide microarrays to interrogate gene expression profiles associated with cell-biomaterial interactions. We seeded collagen-glycosaminoglycan meshes, a widely used tissue engineering scaffold material, with human IMR-90 fibroblasts and compared transcript levels with control cells grown on tissue culture polystyrene. Genes involved in cell signaling, extracellular matrix remodeling, inflammation, angiogenesis and hypoxia were all activated in cells on the collagen-GAG mesh. Understanding the impact of a scaffold on attached cells will facilitate the design of improved tissue engineering materials.
