Fibroblast remodeling activity at two- and three-dimensional collagen-glycosaminoglycan interfaces.

Jaworski Justyn J Klapperich Catherine M CM

Biomaterials 20060418 23

Previously we demonstrated that high throughput gene expression experiments can yield novel information about how cells respond to a collagen-glycosaminoglycan (GAG) three-dimensional culture environment. The goal of the current study was to determine which of these differences result from culture in a three-dimensional construct versus those caused simply by the presence of the collagen-GAG biomaterial. To make this distinction, cells were cultured both in collagen-GAG scaffolds fabricated usin ...[more]

CLIP-seq analysis of WT and Gag chimera HIV-1 virions 3

Project description:To investigate how the major HIV-1 structural protein Gag packages viral genomes efficiently, we replaced the NC domain of Gag with RNA binding domains from heterologous cellular RNA binding proteins to generate Gag chimeras. We hypothesize that the Gag chimeras that preferentially bind to purine-rich RNA sequences will package viral genomes efficiently. We performed CLIP-seq to identify the RNA sequences bound by WT Gag and Gag chimeras in cells, at the plasma membrane, and in virions.

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.

RNA Sequencing of Novel HIV RNA TAR-gag and Host Genome of EVs from HIV-1 Infected Cells

Project description:We performed a 3' RACE of a novel HIV RNA TAR-gag in order to determine the sequence of the RNA at the 3' end. Our data had shown that TAR-gag was potentially a noncoding RNA and our hypothesis was that TAR-gag ended somewhere prior to the end of the gag region of the HIV genome. The 3' RACE experiment showed that TAR-gag actually consists of four different RNA clusters, the longest of which ends at 615 bases from the transcription start site; this is in the middle of the p17 region of the gag gene. In addition, we sequenced all host RNAs in the EVs.

Madin-Darby Canine Kidney (MDCK) cells grown in 2-dimensional and 3-dimensional type I collagen culture.

Project description:In order to gain insight into epithelial morphogenesis and the influence of culture geometry on gene expression patterns, Madin Darby Canine Kidney (MDCK) epithelial cells where grown in 2-dimensional (2D) culture or 3-dimensional (3D) culture . MDCK cells cultured in 2D were plated atop a pre-solidified type I collagen gel. Cells cultured under these conditions grew as flat monolayer sheets. In 3D culture, cells are embedded within type I collagen gel. Cells grown under these conditions form large spherical cysts with hollow central lumens. We anticipate, therefore, that these results provide insight into the mechanisms that regulate epithelial cystogenesis. Cells grown in the 2D or 3D geometries were collected from digested type I collagen gels on day 8. The 2D MDCK cells were treated as the control condition and there gene expression patterns were compared to those of 3D grown cells, which served as the experimental condition.

Determination of Gag stoichiometry for different production platforms by PRM analysis

Project description:In this work we established an analytical method of characterization for the Gag protein core and clarify the current variability of Gag stoichiometry in HIV-1 VLPs depending on the cell-based production platform, directly determining the number of Gag molecules per VLP in each case. Three Gag peptides have been validated to quantify the number of monomers using parallel reaction monitoring (PRM)
