Expression data from tumor-associated endothelial cells of hepatocellular carcinoma

ABSTRACT: Primary uncultured CD31+ and CD105+ tumor endothelial cells (TEC), non-tumor endothelial cells (NEC) ,remnant cells from tumor (TC) and non-tumor liver tissue (NTC)of HCC tissues from patientswere isolated by magnetic-activated cell sorting. Affymetrix Human Gene ST Arrays were used to determine gene expression profiles of HCC cells and matched TEC and NEC cells. We use the gene expression profiling of the Human Genome U133 Plus 2.0 Arrays (Affymetrix, Santa Clara, CA) to identify distinct genes of TEC and NEC. Patient specimens were collected immediately after removal from patients with pathologically proven HCC and positive alpha-fetoprotein (AFP), then washed 3 times by phosphate buffer solution (PBS). Single cell suspension was obtained from separated tumor and non-tumor liver tissues of surgical specimens following the protocol (http://www.miltenyibiotec.com), then CD31+ cells or CD105+ cells were isolated using CD31 antibody or CD105 antibody conjugated magnetic beads in autoMACSpro (Meltenyi biotec).After the sample preparation, the gene expression profiling was performed using the Human Genome U133 Plus 2.0 Arrays (Affymetrix, Santa Clara, CA) according to manufacturerM-bM-^@M-^Ys protocols at ShanghaiBio Corporation (Shanghai, China).

Expression data from Mus musculus white adipose tissue

Project description:We used microarrays to detail the gene expression profile during WAT -beige transition by treatment of beta adrenergic receptor agonist . Stromal vascular fractions (SVF) from mice (n = 3/group) that received vehicle or beta3 adrenergic receptor agonist, CL, treatment were served for RNA extraction and hybridization on Affymetrix microarrays. We are trying to find out angiogenic factors genes dynamics during white adipose tissues (WAT) - beige transition.

Transcriptome analysis of synovial osteoprogenitor populations in mice with antigen-induced arthritis and non-immunized mice

Project description:The aim of this experiment was to analyze differences in gene expression between potential osteoprogenitor populations in synovial compartment of non-immunized mice and mice with antigen-induced arthritis (AIA). We analyzed transcriptome of TER119–CD31–CD45–CD51+CD200+CD105– cells from nonimmunized mice, TER119–CD31–CD45–CD51+CD200+CD105– cells from mice with arthritis, and TER119–CD31–CD45–CD51+CD200–CD105+ from mice with arthritis. Comparison between nonimmunized and arthritic mice served to determine changes in TER119–CD31–CD45–CD51+CD200+CD105–population induced by arthritis. Comparison of TER119–CD31–CD45–CD51+CD200+CD105– and TER119–CD31–CD45–CD51+CD200–CD105+ from mice with arthritis aimed to define transcriptomic differences between those two populations.

CGH_TEC_NEC_PBMC

Project description:Genomic DNA was extracted from tumor endothelial cells (TEC), corresponding normal endothelial cells (NEC) and peripheral blood monoculear cells (PBMC) from patients suffering from colorectal carcinoma. The DNA samples were analyzed by genome-wide human SNP 6.0 arrays and subsequent determination of genome-wide copy numbers.

A tumor endothelial cell-specific microRNA replacement therapy for hepatocellular carcinoma

Project description:Current approved anti-angiogenic drugs (AAD) for hepatocellular carcinoma (HCC) inhibit tumor angiogenesis, but affect the hepatic vasculature resulting in adverse effects. Tumor endothelial cells (TECs) differ from normal endothelial cells. In this study, we aimed to detect TEC-specific miRNAs and develop an anti-angiogenic treatment specific for TECs. We established HCC orthotopic mouse models. TEC-specific miRNAs were detected using a microRNA array. Finally, we evaluated the therapeutic effects of the TEC-specific miRNA agonist cocktail. In total, 260 TEC-specific genes were detected. Among the top ten downregulated TEC-specific miRNAs, miR-139-3p and 214-3p were important for the TEC phenotype. The TEC-specific microRNA agonist cocktail showed significant anti-tumor effects by inhibiting tumor angiogenesis without affecting hepatic vasculatures in HCC orthotopic mouse models. Moreover, it significantly downregulated tip-cell sprouting-related genes. We identified two downregulated TEC-specific miRNAs; microRNA replacement therapy, which targets the downregulated TEC-specific miRNAs, is an effective and promising treatment for HCC

Transcriptomes of CD31+CD34+HEPs with different expression of CD105 derived from human early hematopoietic differentiation by RNA Sequencing

Project description:Purpose: The goals of this study are to dessect the molecular signature of CD31+CD34+HEPs with different expression of CD105 ,and to explore the regulators such as signaling and transcription factors of CD105+ cells' generation. Methods: mRNA profiles of HEPs samples collected at day4 of hematopoietic differentiation were generated by deep sequencing using Illumina HiSeq 2000. The sequence reads that passed quality filters were analyzed at the transcript isoform level with two methods: Burrows–Wheeler Aligner (BWA) followed by ANOVA (ANOVA) and TopHat followed by Cufflinks. qRT–PCR validation was performed using TaqMan and SYBR Green assays Conclusions: The CD31+CD34+CD105-HEPs possess hematopoietic potential whereas the CD31+CD34+CD105+HEPs possess endothelial potential. In addition, the generation of CD105+cells were regulated by TGFbeta signaling and ETS1.

Skeletal Stem Cell Diversity in Mouse Long Bones

Project description:We have used SmartSeq2 to sequence single phenotypic skeletal stem cell (SSCs) populations purified via FACS from adult mouse long bones. Two putative SSC populations were isolated based on their previously reported surface marker profiles. An osteochondrogenic SSC (ocSSC, CD45-CD31-Tie2-Ter119-CD51+6C3-Thy1-CD105-) and a perivascular SSC (pvSSC, CD45-CD31-Pdgfra+Sca1+CD24+) were investigated.
