MetabolomicsNPC1 regulates the distribution of phosphatidylinositol 4 kinases at Golgi and Lysosome membranes
Cholesterol and phosphoinositides (PI) are two critically important lipids that are found in cellular membranes and dysregulated in many disorders. Therefore, uncovering molecular pathways connecting these essential lipids may offer new therapeutic insights. We report that loss of function of lysoso...

TranscriptomicsPhosphatidylinositol 3-Kinase (PI3K) Signaling via Glycogen Synthase Kinase-3 (Gsk-3) Regulates DNA Methylation of Imprinted Loci.
The two vertebrate Gsk-3 isoforms, Gsk-3a and Gsk-3b, are encoded by distinct genetic loci and exhibit mostly redundant function in murine embryonic stem cells (ESCs). Here we report that deletion of both Gsk-3a and Gsk-3b in mouse ESCs results in misregulated expression of imprinted genes and hypom...

ProteomicsAdenovirus E4ORF1 activates isoform-specific phosphatidylinositol 3-kinase signaling
The human adenovirus serotype 5 E4ORF1 (Ad5E4ORF1) protein promotes primary endothelial cell survival and angiocrine functions by hijacking the cellular phosphatidylinositol 3-kinase (PI3K)/AKT signaling pathway. However, the mechanism by which E4ORF1 activates PI3K in vascular cells remains largely...

TranscriptomicsTranscription profiling of human HCMV-Infected monocytes
Human cytomegalovirus induces a pro-inflammatory monocyte following infection and we have evidence that NF-κB and phosphatidylinositol 3-kinase [PI(3)K] are key mediators in this early activation. To begin to address how these signalling pathways are responsible for the rapid activation of infecte...

ProteomicsLabel-free quantitative plasma membrane proteome analysis of Candida glabrata wild-type and Cgvps34∆ (lacks phosphatidylinositol 3- phosphate kinase, CgVps34) strains. Label-free quantitative plasma membrane proteome analysis of Candida glabrata wild-type and Cgvps34∆ (lacks phosphatidylinositol 3- phosphate kinase, CgVps34) strains.
The project is aimed at characterizing the effect of loss of phosphatidylinositol 3- phosphate kinase (CgVps34) on the plasma membrane proteome of Candida glabrata.

ProteomicsRab5a-VPS34 unnatural amino acid mediated crosslinking
The small GTPase Rab5 has an essential role in sorting vesicles arriving to and leaving the early endosome. One key function of Rab5 in this process is the activation of the primordial phosphatidylinositol 3-kinase VPS34, a lipid kinase that phosphorylates phosphatidylinositol (PI) to generate PI3P....

TranscriptomicsGene expression profiling upon PI3K inhibition using different inhibitors
Activation of the phosphoinositide 3-kinase (PI3K)/Akt signaling pathway is one the most frequent genetic events in human cancer. Therefore, the development of PI3K inhibitors has attracted much attention. We previously described the pyrazolopyrimidine derivative ETP-45658 as a potent inhibitor of P...

TranscriptomicsTranscription profiling of neuronal differentiation in two subtypes of SH-SY5Y
Background: SH-SY5Y cells exhibit a neuronal phenotype when treated with all-trans retinoic acid (RA), but the molecular mechanism of activation in the signaling pathway mediated by phosphatidylinositol 3-kinase (PI3K) is not sufficiently understood. To shed new light on the mechanism, we comprehens...

TranscriptomicsTranscription profiling of human prostate cancer cells with arachidonic acid reveals induction of 11 genes that are regulated by NFkappaB
Essential fatty acids (FA) are not only energy-rich molecules; they are also an important component of the membrane bilayer and recently have been implicated in induction of fatty acid synthase (FAS) and other genes. Using gene chip analysis, we have found that arachidonic acid (AA), an omega-6 fat...
