Project description:We analyzed DNA copy number alterations in 64 human gastric cancer samples and 8 gastric cancer cell lines using bacterial artificial chromosome (BAC) arrays based comparative genomic hybridisation (aCGH).
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:Tumor recurrence following a standard treatment is the major cause of mortality for glioblastoma (GBM) patients. However, insights on the evolutionary process of the tumor have been limited due to the lack of longitudinally sampled cases. Here, we describe our genomic analyses of 38 GBM patients with pre- and post-treatment samples for each individual (78 tumor samples in total; aCGH data were obtained for 36 among the 78). A substantial shift in the landscape of driver alterations was associated with distant appearances of the recurrent tumors from the initial tumor, suggesting that the genomic profile of an initial tumor can mislead targeted therapies for the distant recurrent tumor. In addition, in contrast to the previous work on IDH1-R132H low-grade gliomas, our GBM patients rarely developed hypermutation following the standard treatment, supporting the safety of temozolomide for IDH1-wild type, primary GBMs under the current standard regimen.
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.
