MetabolomicsSerine synthesis pathway enzyme PHGDH is critical for muscle cell biomass, anabolic metabolism and mTORC1 signaling

Cells use glycolytic intermediates for anabolism e.g., via the serine synthesis and pentose phosphate pathways. However, we still understand poorly how these metabolic pathways contribute to skeletal muscle cell biomass generation. The first aim of this study was therefore to identify enzymes tha...

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...

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...

MetabolomicsFate and PPARγ and STATs-driven effects of the mitochondrial complex I inhibitor tebufenpyrad in liver cells revealed with multi-omics.
The biological effects of the pesticide and mitochondrial complex I inhibitor tebufenpyrad (TEBU) on liver cells were investigated by combining proteomics and metabolomics. Both cell culture media and cellular lysates were analyzed in dose-response and kinetic experiments on the HepaRG cell line. Re...

MetabolomicsPomegranate Peel Extract as an Inhibitor of SARS-CoV-2 Spike Binding to Human ACE2 Receptor (in vitro): A Promising Source of Novel Antiviral Drugs
Plant extracts are rich in bioactive compounds, such as polyphenols, sesquiterpenes, and triterpenes, which potentially have antiviral activities. As a consequence of the coronavirus disease 2019 pandemic, caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) virus, thousands of...

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...

MetabolomicsInhibition of jasmonic acid-isoleucine conjugating enzyme JAR1 shifts the local and systemic leaf signals and metabolic profiles in Arabidopsis

• Jasmonates (JAs)-mediated pathways are central signaling hubs in plant defense responses. However, the identification of mobile and non-mobile signals involved in downstream systemic signaling is still less studied.

• Here, we investigate the role of the jasmonic acid-isoleucine conjugati...

TranscriptomicsAn alternative, arginase-independent pathway for arginine metabolism in Kluyveromyces lactis involves guanidinobutyrase as a key enzyme
Most available knowledge on fungal arginine metabolism is derived from studies on Saccharomyces cerevisiae, in which arginine catabolism is initiated by releasing urea via the arginase reaction. Orthologs of the S. cerevisiae genes encoding the first three enzymes in the arginase pathway were cloned...
