TranscriptomicsSR Proteins Collaborate with 7SK and Promoter-Associated Nascent RNA to Release Paused Polymerase
RNAP II is frequently paused near gene promoters in mammals and its transition to productive elongation requires active recruitment of P-TEFb, a cyclin-dependent kinase for RNAP II and other key transcription elongation factors. A fraction of P-TEFb is sequestered in an inhibitory complex containing...

TranscriptomicsRainbow trout red blood cells (RBCs): Control vs Heat shock, repeated samples from individuals
The retention of a nucleus in the mature state of fish red blood cells (RBCs), and the ability to easily collect and manipulate blood in non-terminal experiments, makes it an ideal tissue on which to study the cellular stress response in fish. Through the use of the cGRASP 16K salmonid microarray, w...

TranscriptomicsThe RpoN Regulon of Escherichia coli O157:H7
There is increasing evidence to support a role for sigma factor 54 (RpoN) in the regulation of stress resistance factors and protein secretion systems important to bacterial transmission and pathogenesis. In enterohemorrhagic E. coli O157:H7, acid resistance and type III secretion are essential det...

TranscriptomicsTranscription profiling of Porphyromonas gingivalis wild type and mutant PG1432::ermF to identify genes which have their expression influenced by PG1432
The aim of this experiment is to ascertain which genes have their expression influenced by PG1432. PG1432 encodes a putative sensor histidine kinase which is part of two component signal transduction that was highly up-regulated in P. gingivalis mature biofilm cells. PG1432 was disrupted in P. gingi...

TranscriptomicsExpression data from human GBMs
Analysis of human glioblastoma multiforme tumors revealed genes that are upregulated in tumors expressing EGFRvIII compared to those expressing wild-type EGFR We examined gene expression in 52 primary GBM tumors, which were stratified based on the presence or absence of EGFRvIII expression using EGF...

TranscriptomicsExpression data from rat tumors formed by 9L.EV or 9L.EGFRvIII cells
Analysis of rat tumor xenografts revealed genes that are upregulated in tumors expressing EGFRvIII 12 rats received intracranial injections of 9L cells expressing EGFRvIII or an empty vector control. Three weeks after implantation and subsequent growth, tumors were aseptically removed, processed fo...

TranscriptomicsExpression array analysis of the hepatocyte growth factor (HGF) invasive program
HGF stimulates mitogenesis, motogenesis and morphogenesis in most epithelial target cells. Selective inhibition of HGF signaling blocks spontaneous metastasis, but not primary tumor growth, in the prostate adenocarcinoma derived PC3M cell xenograft model. To identify the HGF activated genes and path...

ProteomicsHDX-MS analysis of p110a in complex with regulatory subunits
HDX-MS was used to map the changes in conformational dynamics in the catalytic subunit of PI3Ka, p110a, in complex with the following five reguatory subunits: p85a, p85b, p55g, p55a, p50a. Apo and pY activated states were also compared between the three splice variants encoded by PIK3R1. No signific...

MetabolomicsMetabolic analysis of wound response in Wolbachia infected Drosophila melanogaster

Viral studies of Drosophila melanogaster typically involve virus injection with a small needle, causing post-injury a wounding/wound healing response, in addition to the effects of viral infection. However, the metabolic response to the needle injury is understudied, and many viral investigations...
