Project description:ERG (Ets Related Gene) is an ETS transcription factor that was originally described for its role in a number of human cancers. Our preliminary data demonstrate that ERG exhibits a highly EC restricted pattern of expression in cultured primary cells and several adult tissues including the heart, lung, and brain. In response to inflammatory stimuli, such as TNF-alpha, we observed a marked reduction of ERG expression in EC. To further define the role of ERG in the regulation of normal EC function we used RNA interference to knockdown ERG. Knockdown of ERG in human umbilical vein EC (HUVEC) using siRNA was associated with the reduction of a number known ERG targets. Keywords: SIRNA Functional Role

Project description:We used circular micropattern cultures to differentiate human embryonic stem cells (H1 hESCs) into microcolonies termed ‘gastruloids’, comprising germ layer and extraembryonic cells. Differentiated gastruloids were dissociated and reseeded onto micropatterns in single cells solution to study cell sorting behaviors. We applied single-cell RNA sequencing to examine transcriptomes of gastruloids and reseeded cells.

Project description:Question Addresses: What is the gene expression profile from human umbilical vein endothelial cells (HUVEC) and human Jurkat T cells after irradiation (IR)? What, if any, is the effect of co-culturing these two cell types on gene expression? There are eight experimental conditions for this experiment: (1) non-irradiated HUVEC; (2) irradiated HUVEC; (3) non-irradiated Jurkat; (4) irradiated Jurkat; (5) non-irradiated HUVEC + non-irradiated Jurkat+; (6) non-irradiated HUVEC + irradiated Jurkat; (7) irradiated HUVEC + non-irradiated Jurkat; (8) irradiated HUVEC + irradiated Jurkat. A common, pooled reference consisting of RNA taken from conditions 1-8 as described above was used for all hybridizations.

Project description:Human umbilical vein endothelial cells (HUVEC) were cultivated on 1%-gelatin-coated 75-cm2 culture flasks in Medium 200 supplemented with 2% fetal calf serum, penicillin (100 units/ml), streptomycin (100 units/ml) and Funizone (0.25 μg/ml) supplied by Cascade Biologics (Portland, OR). Prior to an experiment, HUVECs were subcultivated with Trypsin/EDTA onto 1% gelatin coated glass 30-mm glass coverslips in 60 mm glass Petri dishes. The hypoxic treatment was performed in airtight chambers from Mitsubishi Gas Chemical Co. Inc (Remel Scientific, Baton Rouge, LA) Preconditioning consisted of 1-hour hypoxia followed by various periods of reoxygenation (0, 3, 5, 12 and 24 hrs) for gene expression analysis. Total RNA was extracted from cultured HUVECs with TRITM reagent according to the manufacture’s instructions (Molecular Research Center, Cincinnati, OH). Cy5 and Cy3 labeled cDNA probes were generated from total RNA by reverse transcription in the presence of aminoallyl-dUTP according to the method described by Xiang, et al,15. Human universal reference RNA (Stratagene, La Jolla, CA) was Cy3-labeled and used as reference RNA and RNA isolated from HUVEC at 0, 3, 5, 12 and 24 hour following reoxygenation were Cy5-labeled. The high-resolution scans of hybridized microarrays were acquired with a GenePix scanner 4000B (Axon Instruments, Inc., Union City, CA) and tabulated with GenePix pro 5.1 software.

Project description:HUVEC (N=3 isolates) were separately grown to sub-confluency, and to confluency. In order to study the effects of growth and contact inhibition on the transcriptome, the microarray gene expression profiles of these sub-confluent and confluent HUVEC were compared. Keywords: HUVEC, confluency, contact inhibition

Project description:Goal of the experiment : Retroviral-mediated gene transfer of the THAP-zinc finger protein THAP1 inhibits endothelial cell proliferation through coordinated repression of critical cell cycle regulators and pRB-E2F target genes. Experimental design: To gain insight into the effects of THAP1 on endothelial cell growth regulatory pathways, we identified THAP1 target genes in primary human endothelial cells using oligonucleotide-based microarray technology. Human umbilical vein endothelial cells (HUVECs) were transduced with pMLV-MCS or pMLV-THAP1 retroviral expression vectors and, after 48h, cells were harvested for isolation of total RNA and preparation of Cy3- or Cy5-labeled cRNA probes, which were hybridized to DNA microarrays that contained 22 000 unique 60-nt oligonucleotide probes representing > 17 000 human genes. Independent microarray experiments were performed after one (#1xTHAP1) or two (#2xTHAP1) consecutive transductions using independent HUVEC primary cell cultures. Dye swap experiments were performed to eliminate the effect of dye bias, and for each gene probe, the data were subjected to statistical analysis to identify those probes for which a significant difference (p value < 0.01) in mean hybridization intensity was observed between HUVECs transduced with pMLV-MCS or pMLV-THAP1 retroviral expression vectors. Among the gene probes demonstrating a significant difference between the two conditions, we selected those whose expression varied in a similar manner in the two independent microarray experiments. . #2xTHAP1 experiment (Microarrays Code Bars 16011521022012 and 16011521022013): comparison of HUVEC-THAP1 and HUVEC-MCS after two consecutive retroviral transductions of HUVECs with pMLV-THAP1 or pMLV-MCS vectors (higher percentage of genes differentially expressed with p value < 0.01; higher folds) #1xTHAP1 experiment (Microarrays Code Bars 16011521025800 and 16011524025685): comparison of HUVEC-THAP1 and HUVEC-MCS after a single retroviral transduction of HUVECs with pMLV-THAP1 or pMLV-MCS vectors (lower percentage of genes differentially expressed with p value < 0.01; lower folds).

Project description:Substrate topographic patterning is a powerful tool that can be used to manipulate cell shape and orientation. To gain a better understanding of the relationship between surface topography and keratocyte behavior, surface patterns consisting of linear aligned or orthogonally aligned microchannels were used. Photolithography and polymer molding techniques were used to fabricate micropatterns on the surface of polydimethylsiloxane (PDMS). Cells on linear aligned substrates were elongated and aligned in the channel direction, while cells on orthogonal substrates had a more spread morphology. Both linear and orthogonal topographies induced chromatin condensation and resulted in higher expressions of keratocyte specific genes and sulfated glycosaminoglycans (sGAG), compared with non-patterned substrates. However, despite differences in cell morphology and focal adhesions, many genes associated with a native keratocyte phenotype, such as keratocan and ALDH3A1, remain unchanged on the different patterned substrates. This information could be used to optimize substrates for keratocyte culture and to develop scaffolds for corneal regeneration.
