Description
Dengue virus (DENV) infection causes profound changes in the host cells and these changes underlie the immune response-based viral clearance and pathogenesis. There are several major cell/tissue types relevant for DENV pathogenesis in vivo, including immune cells, liver, and vascular endothelial cells. We applied a directed differentiation system that produces hepatocyte-like cells (HLCs) from pluripotent stem cells to investigate various aspects of DENV- hepatic cells interaction. Human embryonic stem cells were resistant to DENV infection while progeny hepatic cells were permissive. The transition to DENV permissiveness coincided with the upregulation of entry factors for the virus. Infection of HLCs by DENV was self-limiting due to the activation of the interferon (IFN) pathways, which protected by-stander cells from infection but failed to induce the same level of interferon-induced genes (ISGs) expression in the infected cells due to the subversion of IFN signaling by DENV. Innate immunity also protected the infected cells from virus-induced apoptosis. Furthermore, DENV infection activated the NF-?B pathway, increased production of reactive oxidative species (ROS), and led to production of inflammatory cytokines which may contribute to the cytokine storm implicated in dengue hemorrhagic fever (DHF). Finally, DENV infection of HLCs resulted several in vitro phenotypes that may have relevance for acute liver failure and vascular permeability during DHF. These include the disruption of adherens junctions and the downregulation of many liver specific genes such as albumin (ALB) and coagulation factor V (F5).

Description
The purpose of this study is to obtain comprehensive gene expression profiles in breast cancer. Mammary gland cells were specifically isolated from 433 clinical tissue samples by laser capture microdissection (LCM). Total RNAs were extracted from LCM captured samples. We investigated gene expression profiles in 417 patients with breast cancer and 16 non-tumor tissues as a normal control using an Affymetrix GeneChip.

Description
ALL is the most common form of childhood cancer with >80% cured with contemporary treatment protocols. Accurate risk stratification in childhood ALL is essential to avoid under- and over-treatment. Currently, we use presenting clinical, biological features, and minimal residual disease (MRD) quantitation to risk stratify patients. Although whole genome gene expression profiling (GEP) can accurately classify patients with ALL into various WHO 2008 defined subgroups, its value in predicting relapse remained to be defined. We hypothesized that global time-series GEPs of bone marrow (BM) samples at diagnosis and specific points during initial remission-induction therapy can measure the success of cytoreduction and be used for relapse prediction.

Description
Chemo-resistance to platinum such as cisplatin is critical in the treatment of ovarian cancer. Recent evidences have linked epithelial-mesenchymal transition (EMT) with the drug resistance as a contributing mechanism. The current study explored the connection between cellular responses to cisplatin with EMT in ovarian cancer.

Description
We have made use of the E-myc transgenic mouse, a model for the study of B-cell lymphoma development that is initiated through a defined genetic alteration, to explore the contributions of additional somatic alterations that contribute to the heterogeneity of the resulting tumors. As one example of such heterogeneity, we have focused on the observation that lymphomas develop in E-myc mice with a variable time of onset. Twenty-five early-onset, 25 late-onset lymphomas and 10 normal samples were each assayed on an Affymetrix Mouse Genome 430 2.0 array.
