Description
Identify genes which are differentially expressed in ?Cop1ß compared to control islets and are also signficantly rescued in ?Cop1? ?ETV1/4/5ß Overall design: Islets were harvested from 5 biological replicates of the followig genotypes: Control, ?Cop1ß and ?Cop1? ?ETV1/4/5ß. Islets were individually handpicked and total RNA was isolated and purified for library preperation and Next Generation Sequencing.

Description
Ubiquilins are a family of proteins involved in proteasomal degradation of mislocalized membrane proteins. Here, Greer et al. demonstrate that Ubqln1 is required for BCR-driven B cell proliferation through maintenance of protein synthesis following stimulation. In the absence of Ubqln1, mitochondrial proteins accumulate in the cytosol, which may account for the observed proteostasis. BCR stimulation of murine B cells induced a long-lasting mitochondrial depolarization that did not occur in response to LPS. We hypothesize that in the absence of Ubqln1, mitochondrial depolarization leads to an accumulation of mitochondrial membrane proteins in the cytosol, which leads to translational inhibition and a cell cycle block. Overall design: For RNASeq, cells were stimulated in triplicate in 2*10e6 cells/mL for 4 hours with either 10 µg/mL anti-IgM F(ab)2 or 20 µg/mL LPS, or no stimulation. There were 18 total samples, 9 Knockout samples, 9 WT samples, 3 biological replicates per treatment group: no stimulation, 10 ug/mL a-Igm, 20 ug/mL LPS.

Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Hepatocellular carcinoma (HCC) is the fifth most-common cancer worldwide causing nearly 600,000 deaths esch year. Approximately 80% of HCC develops on the background of cirrhosis.It is necessary to identify novel genes involved in HCC to implement new diagnostic and treatment options. However, the molecular pathogenesis of HCC largely remains unsolved. Only a few genetic alterations, namely those affecting p53, -catenin and p16INK4a have been implicated at moderate frequencies of these cancers. Early detection of HCC with appropriate treatment can decrease tumor-related deaths

Description
Cellular senescence is a tumor suppressor mechanism, and immortalization facilitates neoplastic transformation. Both mechanisms may be highly relevant to hepatocellular carcinoma (HCC) development and its molecular heterogeneity. Cellular senescence appears to play a major role in liver diseases. Chronic liver diseases are associated with progressive telomere shortening leading senescence that is observed highly in cirrhosis, but also in some HCC. We previously described the generation of immortal and senescence-programmed clones from HCC-derived Huh7 cell line.

- Affymetrix Zebrafish Genome Array (zebrafish)
Description
Nucleosome arrangement in promoter regions has been shown to play an important role in gene regulation. Genome wide studies in yeast, flies, worms, mammalian ES and transformed cell lines have found well positioned nucleosomes with an area of nucleosome depletion flanking transcription start sites. This Nucleosome arrangement has been shown to be dependent on sequence (cis-regulatory factors), DNA binding factors (trans-regulatory factors) and ATP-dependant chromatin modifiers. However, little is understood about how the nascent embryonic genome positions nucleosomes during development. This is particularly intriguing since the embryonic genome undergoes a whole scale rechromatinization event upon fusion of sperm and oocyte. Using four stages of early embryonic zebrafish development we map nucleosome positions at the promoter region of 34 zebrafish hox genes. We find that nucleosome arrangement at the hox promoters is a dynamic process which happens over several stages. We also find evidence that trans-regulatory factors play a greater role in nucleosome positioning over cis-regulatory elements. Finally we provide evidence that transcriptional activation is the driving force behind the arrangement of nucleosomes at the promoters of hox gene during early development.
