MetabolomicsTargeting PI3K inhibitor resistance in breast cancer with metabolic drugs

Activating PIK3CA mutations, present in up to 40% of hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (Her2-) breast cancer (BC) patients, can be effectively targeted with the alpha isoform-specific PI3K inhibitor Alpelisib. This treatment significantly improves ...

MetabolomicsMicrobiome Metabolism of Dietary Phytochemicals Controls the Anticancer Activity of PI3K Inhibitors
Phosphatidylinositol 3-kinase (PI3K) signaling is both the effector pathway of insulin and among the most frequently activated pathways in human cancer. In murine cancer models, the efficacy of PI3K inhibitors is dramatically enhanced by a ketogenic diet, with a proposed mechanism involving dietary ...

MetabolomicsDietary High Fiber and N-Carbamylglutamate Enhance Sow Reproductive Performance via Modulating Lactobacilli, Lipid Metabolites, and the PI3K-Akt Signaling Pathway

Background Both high fiber diet and N-Carbamylglutamate (NCG) individually contributes to improve reproductive efficiency in sow. However, the potential synergistic effects and the underlying mechanisms are not well-understood. Here, Landrace x Yorkshire sows were selected to investigate the syne...

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...

TranscriptomicsResistance to PI3K/mTOR inhibitor PF-04691502 in KRAS mutant colorectal cancer models reveals a sensitivity to combination with EGFR inhibition
We explored potential bypass mechanisms to PI3K/mTOR-directed therapy in KRAS mutant CRC models, utilizing genetically engineered mouse models (GEMM) to generate acquired resistance to the targeted dual PI3K/mTOR small molecule inhibitor PF-04691502. Transcriptomic analysis revealed a dynamic stem-l...

TranscriptomicsComparative study of a mTOR inhibitor, a pan-PI3K inhibitor and a dual PI3K/mTOR inhibitor in MCL
Phosphatidylinositol-3-kinase (PI3K)/Akt/mammalian target of rapamycin (mTOR) pathway activation contributes to mantle cell lymphoma (MCL) pathogenesis and drug resistance. However, the use of mTOR inhibitors as single agents have shown limited clinical efficacy in relation with drug activation of f...

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, ...

ProteomicsNaringenin targets PI3K p85alpha to suppress PI3K/AKT signaling pathway and ameliorate disordered MMP-9 secretion in cigarette smoke extract-induced alveolar macrophages in vitro
Naringenin has demonstrated potential therapeutic effects against cigarette smoke-induced lung injury; however, its underlying mechanisms of regulating matrix metalloproteinase-9 (MMP-9) in alveolar macrophages remain unclear. Methods: The regulatory mechanisms of naringenin in cigarette smoke extra...

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...
