MetabolomicsMetabolic effects of an aspartate aminotransferase-inhibitor on two T-cell lines
An emerging method to help elucidate the mode of action of experimental drugs is to use untargeted metabolomics of cell-systems. The interpretations of such screens are however complex and more examples with inhibitors of known targets are needed. Here two T-cell lines were treated with an inhibitor...

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...

MetabolomicsThe phosphofructo-2-kinase/fructose-2,6-bisphosphatase-3 inhibitor 3PO is a modulator of neutrophil metabolism, ROS production and NET release
Neutrophils are key effector leukocytes of the innate immune system and play a pivotal role in defending the host against microbial infections. Recent studies have identified a crucial link between glycolysis and neutrophil cellular functions. We have investigated in human neutrophils, the intricate...

MetabolomicsGlutamine-restricted diets restore sensitivity to KRASG12D inhibitor through the reversal of ANXA1-mediated metabolic reprogramming
This study investigates the mechanisms underlying KRASG12D inhibitor resistance and evaluates strategies to enhance treatment sensitivity. Our findings indicate that a glutamine-restricted diet not only reverses KRASG12D inhibitor resistance in PDAC but also achieves durable remission with long-term...

ProteomicsUse of a modified Multiplexed Inhibitor Bead assay to study kinome responses to cytostatic treatment in human cancer cell lines Triplicate Test: pilot study
In order to improve elution of proteins from the column, to reduce the cost as well as the hands on time of the analysis, we here present a modification of the Multiplexed Inhibitor Bead assay (MIB assay), where we elute the proteins from beads containing covalently bound inhibitors using trypsin di...

ProteomicsDetermining MELK inhibitor specificity using MIB/MS
The key objectives of this study were to evaluate the selectivity profiles of three MELK inhibitors, 8a, HTH, and OTS, using a cell-based assay, in order to identify a highly selective inhibitor to subsequently investigate MELK function. To this end, we utilized a chemical proteomics approach called...

ProteomicsKinome Profiling of Primary Endometrial Tumors Using Multiplexed Inhibitor Beads and Mass Spectrometry Identifies SRPK1 As A Candidate Therapeutic Target
Protein kinases (collectively termed the kinome) represent one of the most tractable drug targets in the pursuit of new and effective cancer treatments. However, less than 20% of the kinome is currently being explored as primary targets for cancer therapy, leaving the majority of the kinome untarget...

ProteomicsSolvent Precipitation SP3 (SP4) enhances recovery for proteomics sample preparation without magnetic beads
Complete, reproducible extraction of protein material is essential for comprehensive and unbiased proteome analyses. A current gold standard is single-pot, solid-phase-enhanced sample preparation (SP3), in which organic solvent and magnetic beads are used to denature and capture protein aggregates, ...

TranscriptomicsStably-paused genes revealed through inhibition of transcription initiation by the TFIIH inhibitor Triptolide
Transcription by RNA Polymerase II (Pol II) in metazoan is regulated in several steps, including preinitiation complex (PIC) formation, initiation, Pol II escape, productive elongation, cotranscriptional RNA-processing and termination. Genome-wide studies have demonstrated that the phenomenon of ...
