Description
We report the expression profiles of MCF10A cells encapsulated in hydrogels of varying stiffness and composition. Cells were encapsulated for 7 days in either 1.) soft alginate and reconstituted basement membrane (rBM), 2.) stiff alginate and rBM, 3,) soft col-1 and rBM, or 4.) stiff col-1. We find global gene expression changes in response to enhanced ECM stiffness, independent of expression changes in response to col-1 exposure. These results provide a comprehensive study of the gene expression changes associated with increased ECM stiffness in addition to the gene expression changes associated with increased col-1 concentration in combination with, and independent of, ECM stiffness. Overall design: Expression profiling of MCF10A cells in four hydrogel conditions were sequenced in duplicate via Illumina HiSeq.

Description
Infection of Kaposi's sarcoma associated herpes virus (KSHV) has been linked to the development of primary effusion lymphoma (PEL), which is characterized by the loss of expression of B cell markers and effusions in the body cavities. This unique clinical feature of PEL has been attributed to their distinctive gene expression profile which shows overexpression of genes in various signaling pathways. KSHV-encoded latent protein vFLIP K13 has been shown to promote the survival and proliferation of PEL cells. In this study, we have employed gene array analysis followed by bioinformatics analysis of coordinated transcriptional factors network as well as biological pathways to characterize the effect of K13 on PEL-derived BCBL1 cells. We observed that genes associated with Cytokine signaling, Cell death, NF-kappaB and Cell adhesion pathways were differentially regulated by K13.

Description
Malignancies arising from mutation of tumor suppressor genes display an unexplained tissue proclivity. For example, tumor suppressor BAP1 encodes a ubiquitously expressed deubiquitinase for histone H2A but germline mutations predominantly cause uveal melanomas and mesotheliomas. We show that BAP1 inactivation causes apoptosis in mouse embryonic stem cells, fibroblasts, liver and pancreas, whereas melanocytes and mesothelial cells remain viable. E3 ligase RNF2, which silences genes by monoubiquitinating H2A, promoted apoptosis in BAP1-deficient cells by suppressing the pro-survival genes Bcl-2 and Mcl-1. Our data argue that BAP1 modulates gene expression by countering H2A ubiquitination, but its loss only promotes tumorigenesis in cells that do not engage an RNF2-dependent apoptotic program. We propose that intolerance of BAP1 loss, and perhaps the loss of other tumor suppressors, restricts the mutant tumor spectrum. Overall design: RNA was extracted from following genotypes - BAP1 wt (WT) and BAP1 knockout (BAP1 KO).

Description
Screening small molecules and drugs for activity to modulate alternative splicing, we found that amiloride, distinct from four other intracellular pH-affecting analogues, could normalize the splicing of BCL-X, HIPK3 and RON/MISTR1 transcripts in human hepatocellular carcinoma Huh-7 cells. To elucidate the underlying mechanisms, our proteomic analyses of amiloride-treated cells detected hypo-phosphorylation of splicing factor SF2/ASF and also decreased levels of SRp20 and two un-identified SR proteins. We further observed decreased phosphorylation of AKT, ERK1/2 and PP1, while increased phosphorylation of p38 and JNK, suggesting that amiloride treatment down-regulated kinases and up-regulated phosphatases in the signal pathways known to affect the splicing factor protein phosphorylation. The amiloride effects of splicing factor protein hypo-phosphorylation andnormalizedoncogenic RNA splicing were both abrogated by pre-treatment with a PP1 inhibitor. We then performed global exon array analysis of Huh-7 cells treated with amiloride for 24 hours. Using gene array chips (Affymetrix GeneChip Human Exon 1.0 ST Array of >518000 exons of 42974 genes) for exon array analysis (set parameters of correlation coefficient 0.7, splicing index -1.585 , and log2 ratio -1.585), we found that amiloride influenced the splicing patterns of 551 genes involving at least 584 exons, which included 495 known protein-coding genes involving 526 exons, many of which play key roles in functional networks of ion transport, extracellular matrix, cytoskeletons and genome maintenance. Cellular functional analyses revealed subsequent invasion and migration defects, cell cycle disruption, cytokinesis impairment, and lethal DNA degradation in amiloride-treated Huh-7 cells. This study thus provides mechanistic underpinnings for exploiting small molecule modulation of abnormal RNA splicing for cancer therapeutics.

Description
Integrated microarray and multiplex cytokine analyses of Kaposi's Sarcoma Asssociated Herpesvirus viral FLICE Inhibitory Protein K13 affected genes and cytokines in human blood vascular endothelial cells. The KSHV-encoded K13 protein is one of the few proteins to be expressed in latently-infected spindle cells and the ectopic expression of K13 in human vascular endothelial cells is sufficient to transform them into spindle cells.
