MetabolomicsTargeting SLC1A5-mediated glutamine metabolism overcomes PARP inhibitor resistance in ovarian cancer

Poly(ADP-ribose) polymerase inhibitors (PARPi), such as olaparib, have significantly improved outcomes in ovarian cancer (OC); however, therapy resistance remains a major clinical challenge. Here, we showed that glutamine metabolism was upregulated in PARPi-resistant OC cells and identified the g...

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...

ProteomicsTEAD inhibitor K-975 enhances KRASG12C inhibitor adagrasib-mediated cancer cell proliferation inhibition via dual cell cycle arrest
Here we investigate the effect of the dual inhibition, in KRASG12C mutated NSCLC cells, using the KRASG12Ci adagrasib (MRTX849) and the pan-TEAD inhibitor (TEADi) K-975. We show that K-975 enhances adagrasib-induced tumor cell growth inhibition in cancer cells. Mechanistically, we detect a downregul...

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...

TranscriptomicsDual regulation of Fbw7 function and oncogenic transformation by Usp28
Fbw7, the substrate recognition subunit of SCF(Fbw7) ubiquitin ligase, mediates turnover of multiple proto-oncoproteins and promotes its own degradation. Fbw7-mediated substrate degradation is antagonized by the Usp28 deubiquitinase. We now show, using knockout mice, that Usp28 preferentially deubiq...

TranscriptomicsGenome-wide analysis of 5-hydroxymethylcytosine distribution reveals its dual function in transcriptional regulation in mouse embryonic stem cells
Recent studies have demonstrated that the Ten-eleven translocation (Tet) family proteins can enzymatically convert 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC). While 5mC has been studied extensively, little is known about the distribution and function of 5hmC. Here we present a genome...

TranscriptomicsThe tinkerbell (tink) mutation identifies the dual-specificity MAPK phosphatase INDOLE-3-BUTYRIC ACID-RESPONSE5 (IBR5) as a novel regulator of organ size in Arabidopsis.
Mitogen-activated dual-specificity MAPK phosphatases are important negative regulators in the MAPK signalling pathways responsible for many essential processes in plants. In a screen for mutants with reduced organ size we have identified a mutation in the active site of the dual-specificity MAPK ph...
