TranscriptomicsMapping and characterization of promoter-binding sites of protein phosphatase 1
Protein phosphatase 1 (PP1) is a Ser/Thr phosphatase that has been implicated in many key cellular functions including transcriptional regulation. Due to its involvement these many processes, it becomes difficult to directly link PP1 to transcriptional regulation on the chromatin level as no direct ...

ProteomicsThe C. elegans ASPP homolog APE-1 is a junctional Protein Phosphatase 1 modulator
Protein samples were analyzed by Multidimensional Protein Identification Technology (MudPIT), as described previously. Briefly, precipitated proteins were resuspended in 30uL of 100mM Tris pH 8.5 with 8M urea to denature proteins. Cysteines were reduced and alkylated prior to digestion with recombi...

ProteomicsIdentification of Mitogen-Activated Protein Kinase Phosphatase-1 (MKP-1) protein partners using Tandem Affinity Purification and Mass Spectrometry
According to the World Health Organization Report, depressive disorders affect about 10% of the population. The molecular mechanism of the pathogenesis of depression is still not well understood. The new findings point to phosphatases as potential targets for effective depression therapy. The aim of...

MetabolomicsOverexpression of vesicle-associated membrane protein PttVAP27-17 as a tool to improve biomass production and the overall saccharification yields in Populus trees

Background

Bioconversion of wood into bioproducts and biofuels is hindered by the recalcitrance of woody raw material to bioprocesses such as enzymatic saccharification. Targeted modification of the chemical composition of the feedstock can improve saccharification but this gain is often abr...

MetabolomicsNew plasma preparation approach to enrich metabolome coverage in untargeted metabolomics: plasma protein bound hydrophobic metabolite release with proteinase K
Plasma untargeted metabolomics is a common method for evaluation of the mechanisms underlying human pathologies and identification of novel biomarkers. The plasma proteins provide the environment for transport of hydrophobic metabolites. The current sample preparation protocol relies on the immediat...

TranscriptomicsTranscription profiling of spleens from dual specificity phosphatase-1 (DUSP1) deficient and wild type mice to demonstrate a specific regulatory role of DUSP1 on a subset of LPS-induced genes that control the outcome of endotoxin shock.
Activation of the Mitogen activated protein kinase (MAPK) cascade following Toll-like receptor (TLR) stimulation enables innate immune cells to rapidly activate cytokine gene expression. A balanced response to signals of infectious danger requires that cellular activation is transient. Here, we iden...

MetabolomicsIdentification of BolA protein reveals a novel virulence factor in Klebsiella pneumoniae that contributes to liver abscess in mice

BolA has been characterized as an important transcriptional regulator, which is induced in the stationary phase of growth and is often associated with bacterial virulence. This study was initiated to elucidate the role of the BolA in the virulence of K. pneumoniae. Using a mous...

MetabolomicsThe novel protein circPETH-147aa regulates metabolic reprogramming in hepatocellular carcinoma cells to remodel immunosuppressive microenvironment
Metabolic reprogramming fuels cancer cell metastasis and remodels the immunosuppressive tumor microenvironment (TME). We report here that a circRNA, circPETH, packaged by extracellular vesicles (EVs) from tumor-associated macrophages (TAMs) to hepatocellular carcinoma (HCC) cells, facilitates glycol...

TranscriptomicsIntegrative transcriptome profiling of cognitive aging and its preservation through Ser/Thr protein phosphatase regulation
Environmental enrichment has been reported to delay or restore age-related cognitive deficits, however, a mechanism to account for the cause and progression of normal cognitive decline and its preservation by environmental enrichment is lacking. Using genome-wide SAGE-Seq, we provide a global assess...

TranscriptomicsTCR affinity-dependent functional inhibition via PD-1 and SHP-1 phosphatase
To investigate gene expression changes associated with stimulation of TCRs of different affinity, primary CD8 T cells were transduced with sequence optimized TCRs of various affinities and stimulated for 6h. Gene expression was measured at baseline (0h) and after 6h after stimulation with low dose N...
