MetabolomicsUntargeted lipid profiling following mTOR inhibition

The mechanistic target of rapamycin (mTOR) is pivotal in programming cellular lipid homeostasis for the structural and functional integrity of cells. Dysregulation of mTOR and consequent altered lipid metabolism are common features in various diseases, including cancers, making mTOR signaling a p...

MetabolomicsSelective mTOR inhibition via FLCN drives TFE3-dependent VLDL-TG secretion and protects from MAFLD/MASH
Hepatic lipid homeostasis is controlled by multiple processes, including VLDL-TG secretion. We have previously shown that the FLCN/TFE3 branch of mTORC1 signaling controls hepatic fatty acid oxidation and de novo lipogenesis to protect mice from MAFLD. We now show that the FLCN/TFE3 pathway also con...

TranscriptomicsGene expression profiles of effector T cells induced by mTOR inhibition
To further develop our gene expression approach to treatment of autoimmunity, we have employed whole genome microarray expression profiling as a discovery platform to identify genes differentially expressed upon immunosuppressor treatment responsible for inhibition of T cell effector functions. Huma...

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...

ProteomicsProteomic profiling of colorectal cancer cell culture samples treated with apoptosis- and mTOR inhibitors under normoxia and hypoxia
To examine changes in tyrosine kinase activity in colorectal cancer cell culture samples treated with apoptosis inhibitors or/and mTOR inhibitors, under normoxic or/and hypoxic experimental conditions.

TranscriptomicsThe TSC/mTOR pathway regulates the innate inflammatory response
The TSC/mTOR (tuberous sclerosis complex/mammalian target of rapamycin) pathway has a central role in cell growth and is involved in human tumorigenesis. Here, we demonstrate an unexpected role of TSC2 and mTOR in regulating key inflammatory cytokines in monocytes, macrophages, and dendritic cells a...

TranscriptomicsTLR-mediated type I IFN induction in pDCs requires the rapamycin-sensitive PI3K-mTOR-p70S6K pathway
Robust type I interferon (IFN-alpha/beta) production in plasmacytoid dendritic cells (pDCs) is critical for anti-viral immunity. Here we demonstrated a role for the mammalian target of rapamycin (mTOR) pathway in regulating interferon production by pDCs. Inhibition of mTOR or the ‘downstream’ mediat...

TranscriptomicsTargeting the MTOR-AKT pathway in DLBCL
The mTOR (mammalian Target of Rapamycin) pathway is constitutively activated in Diffuse Large B-Cell Lymphoma (DLBCL). mTOR inhibition has been shown to have clinical activity in patients with DLBCL, although overall response rates remain low. We therefore evaluated differences in the transcriptome...

TranscriptomicsFriends not foes: CTLA-4 blockade and mTOR inhibition cooperate during CD8+ T cell priming
T cells receive numerous positive and negative signals during primary antigen encounter that control their proliferation and function, but how these signals are integrated to modulate T cell memory has not been fully characterized. In these studies, we demonstrate that combining seemingly opposite ...

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...
