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...

TranscriptomicsEffect of a dual specificity PI3K/mTOR inhibitor, NVP-BEZ235, on human ovarian cancer cell lines grown in 3D culture
Analysis of the effects of a dual specificity PI3K/mTOR inhibitor on two human ovarian cell lines, OV2008 and MCAS. Results provide insight into the adaptive response to PI3K/mTOR inhibition in matrix attached ovarian cancer cells. The PI3K/mTOR-pathway is the most commonly deregulated pathway in e...

TranscriptomicsComparison of gene expression alterations induced by distinct PI3K inhibitors
The goal is the characterization of the off-target activity of BKM120 observed in A2058 human melanoma cell line at IC90 concentration (3.606 µM) but not at lower concentrations. Controls are BEZ235, GDC0941, showing no off-target activity. A secondary objective is the characterizations of drug eff...

ProteomicsMultiomic analysis of PI3K in Atrial Myopathy
Here, we undertook comprehensive physiological and molecular analyses in cardiac-specific transgenic mice with increased or decreased PI3K to assess the dose response impact of directly regulating PI3K. Elevated PI3K was associated with a dose-dependent increase in heart size, and preserved/enhanced...

TranscriptomicsAltered modulation of WNT-β-catenin and PI3K/Akt pathways in IgA nephropathy
To uncover new molecular mechanisms involved in IgAN pathogenesis, we compared the genomic profiles of 12 IgAN patients with 8 healthy subjects, We included addiotional disease controls 3 FSGS(Focal Segmenal glomerulosclerosis) patients and 3 membrano proliferative glomerulonephritis type I (MPGN-I)...

ProteomicsTargeting of disease-linked mutations in PI3K gamma
Using hydrogen deuterium exchange mass spectrometry (HDX-MS) and molecular dynamics we have identified mutation specific conformational changes, and provide a molecular framework for how they alter kinase activity.Many of the activating conformational changes mimicked previously described changes th...

TranscriptomicsTranscription profiling of human gamma-secretase inhibitor-sensitive and -resistant T-ALL cell lines
Gain-of-function mutations in NOTCH1 are common in T-cell lymphoblastic leukemias making this receptor a promising target for drugs such as gamma-secretase inhibitors, which block a proteolytic cleavage required for NOTCH1 activation. However, the enthusiasm for these therapies has been tempered by ...

TranscriptomicsFOXO3a Is A Major Target Of Inactivation By PI3K/AKT Signaling In Aggressive Neuroblastoma
Neuroblastoma is a pediatric tumor of the peripheral sympathetic nervous system with a highly variable prognosis. Activation of the PI3K/AKT pathway in neuroblastoma is correlated with poor patient prognosis, but the precise downstream effectors mediating this effect have not been determined. Here, ...

TranscriptomicsAnalysis of miRNA profiles identified miR-196a as a crucial mediator of aberrant PI3K/AKT signalling in lung cancer cells
Hyperactivation of the PI3K/AKT pathway is observed in most NSCLCs, promoting proliferation, migration and resistance to therapy. AKT can be activated through several mechanisms that include loss of the negative regulator PTEN, activating mutations of the catalytic subunit of the positive regulator ...
