IlluminaGenomeAnalyzerIIx
Description
We have sequenced the polysome-associated translating mRNAs from stage-matched wild-type and eif3ha morphant embryos at ~24 hpf stage to identify transcripts translationally regulated by eIF3ha. As a control, we have also sequenced total mRNAs from the stage-matched wild-type and eif3ha morphants as well at ~ 24 hpf. Overall design: Polysome-associated mRNAs were isolated from 300 zebrafish embryos. Total RNA was isolated from 50 zebrafish embryos. Single 36-base pair reads were sequenced on the Illumina Genome Analyzer Iix.

Affymetrix Human Genome U95 Version 2 Array (hgu95av2)
Description
Ulcerative colitis (UC) and Crohns disease (CD) are inflammatory bowel diseases (IBD) with variable, overlapping clinical features and complex pathophysiologies. To identify pathogenic processes underlying these disease subtypes, using single endoscopic pinch biopsies to estabolish 36 expression profiles, we elucidated gene expression patterns of active and inactive areas of UC and CD, and compared these to infectious colitis and healthy controls.
Publication Title
Genome-wide gene expression differences in Crohn's disease and ulcerative colitis from endoscopic pinch biopsies: insights into distinctive pathogenesis.

Description
Pancreatic ductal adenocarcinoma (PDAC) is a nearly uniformly lethal malignancy, with most patients facing an adverse clinical outcome. Given the pivotal role of aberrant Notch signaling in the initiation and progression of PDAC, we investigated the effect of MRK-003, a potent and selective -secretase inhibitor, in preclinical PDAC models. We used a panel of human PDAC cell lines, as well as patient-derived PDAC xenografts, to determine whether pharmacological targeting of the Notch pathway could inhibit pancreatic tumor growth and potentiate gemcitabine sensitivity. In vitro, MRK-003 treatment downregulated the canonical Notch target gene Hes-1, significantly inhibited anchorage independent growth, and reduced the subset of CD44+CD24+ and aldehyde dehydrogenase (ALDH)+ cells that have been attributed with tumor initiating capacity. Ex vivo pretreatment of PDAC cells with MRK-003 in culture significantly inhibited the subsequent engraftment in immunocompromised mice. In vivo, MRK-003 monotherapy significantly blocked tumor growth in 5 of 9 (56%) patient-derived PDAC xenografts. Moreover, a combination of MRK-003 and gemcitabine showed enhanced antitumor effects compared to gemcitabine alone in 4 of 9 (44%) PDAC xenografts. Baseline gene expression analysis of the treated xenografts indicated that upregulation of nuclear factor kappa B (NFB) pathway components was associated with the sensitivity to single MRK-003, while upregulation in B-cell receptor (BCR) signaling and nuclear factor erythroid-derived 2-like 2 (NRF2) pathway correlated with response to the combination of MRK-003 with gemcitabine. The preclinical findings presented here provide further rationale for small molecule inhibition of Notch signaling as a therapeutic strategy in PDAC.

Description
In this study Panc-1 cells and BxPC-3 cells were cultured. The cells were harvested (untreated control 'cont') for RNA extraction, or treated for 3 hours with various exosomes preparations. The exosomes were collected from BJ human foreskin fibroblast culture supernatant without further processing (control exosomes or 'CE'), or engineered to contain scrambled siRNA ('scr') or KRASG12D siRNA ('iExo). Two or three distinct wells of cells were evaluated per treatment condition and assigned a well number (well -1, -2 or 3).
