Project description:Thymidine phosphorylase (TP) catalyzes the reversible phosphorolysis of thymidine, deoxyuridine, and their analogs to the respective bases and 2-deoxy-D-ribose-1-phosphate. TP is identical to platelet-derived endothelial cell growth factor (PD-ECGF). TP was reported to induce many angiogenic factors. However, the molecular mechanism of the TP function is still obscure. To elucidate the molecular basis for the TP function in human epidermoid carcinoma KB cells, we performed a whole genome-wide microarray analysis. Genes upregulated in KB cells overexpressing TP are supposed to represent potential molecular targets of TP in KB cells.

To elucidate the molecular basis for the TP function in human epidermoid carcinoma KB cells, we performed a whole genome-wide microarray analysis. Genes upregulated in KB cells overexpressing TP are supposed to represent potential molecular targets of TP in KB cells. KB cells (4 M-CM-^W 10^5) in 5 ml of culture media were cultured for 24 hours, then the growth medium was replaced with serum-free medium. These cells were maintained at 37 M-KM-^ZC in a humidified atmosphere of 5% CO2 for 12 hours, then these cells were collected for RNA extraction and quantification of the transcripts by microarray analysis.
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
Project description:Gene methylation profiling of immortalized human mesenchymal stem cells comparing HPV E6/E7-transfected MSCs cells with human telomerase reverse transcriptase (hTERT)- and HPV E6/E7-transfected MSCs. hTERT may increase gene methylation in MSCs. Goal was to determine the effects of different transfected genes on global gene methylation in MSCs.
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs. One-condition experment, gene expression of 3A6
Project description:To investigate the role of RIG-I activation and thymidine phosphorylase inhibition human endothelial cells, we used a dsRNA agonist on HUVECs and HMVECs to activate RIG-I signaling, and further treated with tymp inhibitor TPI. We then performed differential gene expression analysis using data obtained from RNA-seq from each treatment group.
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression. Two-condition experiment, Normoxic MSCs vs. Hypoxic MSCs.
Project description:Single-nucleus RNA sequencing (snRNA-seq) was used to profile the transcriptome of 16,015 nuclei in human adult testis. This dataset includes five samples from two different individuals. This dataset is part of a larger evolutionary study of adult testis at the single-nucleus level (97,521 single-nuclei in total) across mammals including 10 representatives of the three main mammalian lineages: human, chimpanzee, bonobo, gorilla, gibbon, rhesus macaque, marmoset, mouse (placental mammals); grey short-tailed opossum (marsupials); and platypus (egg-laying monotremes). Corresponding data were generated for a bird (red junglefowl, the progenitor of domestic chicken), to be used as an evolutionary outgroup.
