Description
GBM is a heterogenous brain tumor with hyperproliferation of endothelial cells. In order to understand the cellular mechanism of vasculogenesis in GBM, four fractions of cells are seperated. Microarray assays was performed to examine the potential lineage relationship and the signal pathways involved in determining the cell identity and function.

Description
Using oligonucleotide microarray analysis, we identified 56 genes that were transcriptionally up-regulated and 69 that were suppressed upon exposure of endothelial cells to C. albicans. Among the regulated genes those attributed to the categories chemotaxis, signaling, and transcription and translation were remarkably overrepresented.
Publication Title
Candida albicans triggers activation of distinct signaling pathways to establish a proinflammatory gene expression program in primary human endothelial cells.

Description
EGFR inhibitors (EGFRi) are effective against EGFR mutant lung cancers. The efficacy of these drugs however is mitigated by the outgrowth of resistant cells, most often driven by a secondary acquired mutation in EGFR, T790M. We recently demonstrated that T790M can arise de novo during treatment (Hata et al., Nature Medicine 2016); it follows that one potential therapeutic strategy to thwart resistance would be identifying and eliminating these cells (referred to as drug tolerant cells (DTCs)) prior to acquiring secondary mutations like T790M. We have developed DTCs to EGFRi in EGFR mutant lung cancer cell lines. Subsequent analyses of DTCs included RNA-seq, high-content microscopy, and protein translational assays. Based on these results, we tested the ability of MCL-1 BH3 mimetics to combine with EGFR inhibitors to eliminate DTCs and shrink EGFR mutant lung cancer tumors in vivo. Overall design: The NSCLC cell line PC9 was made tolerant to gefitinib over 6-days. Replicates were performed at a minimum of duplicates.

- Affymetrix Drosophila Genome 2.0 Array (drosophila2)
Description
Centrosome defects are a common feature of many cancers. Surprisingly, flies can proceed through the majority of development without centrosomes or with amplified centrosomes in most of their cells. It is unclear whether this is because centrosome defects do not cause many problems in Drosophila cells, or because they can adapt to cope with any problems that arise. Indeed, centrosome loss and centrosome amplification predispose fly brain cells to form tumours. Here we assess how centrosome loss or centrosome amplification perturbs cell physiology by profiling the global transcriptome of Drosophila larval brains and imaginal discs that either lack centrosomes or have too many centrosomes.
Publication Title
Centrosome loss or amplification does not dramatically perturb global gene expression in Drosophila.

Description
Ewing sarcoma family of tumors (ESFT) are aggressive bone and soft tissue tumors of unknown cellular origin. Most ESFT express EWS-FLI1, a chimeric protein which functions as a growth-promoting oncogene in ESFT but is toxic to most normal cells. A major difficulty in understanding EWS-FLI1 function has been the lack of an adequate model in which to study EWS-FLI1-induced transformation. Although the cell of origin of ESFT remains elusive, both mesenchymal (MSC) and neural crest (NCSC) have been implicated. We recently developed the tools to generate NCSC from human embryonic stem cells (hNCSC). In the current study we used this model to test the hypothesis that neural crest-derived stem cells are the cells of origin of ESFT and to evaluate the consequences of EWS-FLI1 expression on human neural crest biology.

Modeling initiation of Ewing sarcoma in human neural crest cells.
