MetabolomicsHypoxia Dependent Inhibition of Glioblastoma Cell Proliferation, Invasion, and Metabolism by the Choline-Kinase Inhibitor JAS239
Background: Elevated choline kinase alpha (ChoK) levels are observed in most solid tumors, including glioblastomas (GBM), and ChoK inhibitors have demonstrated limited efficacy in GBM models. Given that hypoxia is associated with resistance to GBM therapy, we hypothesized that tumor hypoxia c...

MetabolomicsDissection of two routes to naïve pluripotency using different kinase inhibitors
Embryonic stem cells (ESCs) can be maintained in the naïve state through inhibition of Mek1/2 and Gsk3 (2i). A relevant effect of 2i is the inhibition of Cdk8/19, which are negative regulators of the Mediator complex, responsible for the activity of enhancers. Inhibition of Cdk8/19 (Cdk8/19i) stimul...

MetabolomicsThe ULK3 kinase is a key determinant of keratinocyte self-renewal and tumorigenesis targeting the arginine methylome
Epigenetic mechanisms oversee epidermal homeostasis and oncogenesis. The identification of kinases controlling these processes has direct therapeutic implications. We show that ULK3 is a nuclear kinase with elevated expression levels in squamous cell carcinomas (SCCs) arising in multiple body sites,...

MetabolomicsMetabolic profiling of rheumatoid arthritis neutrophils reveals altered energy metabolism that is not affected by JAK inhibition
Neutrophils play a key role in the pathophysiology of rheumatoid arthritis (RA) where release of ROS and proteases directly causes damage to joints and tissues. Neutrophil function is directly affected by Janus Kinase (JAK) inhibitor drugs, including tofacitinib and baricitinib, which are clinically...

MetabolomicsInhibition of IRAK4 by microbial trimethylamine blunts metabolic inflammation and ameliorates glycemic control - NMR data

The global type 2 diabetes epidemic is a major health crisis and there is a critical need for innovative strategies to fight it. Although the microbiome plays important roles in the onset of insulin resistance (IR) and low-grade inflammation, the microbial compounds regulating these phenomena rem...

MetabolomicsInhibition of IRAK4 by microbial trimethylamine blunts metabolic inflammation and ameliorates glycemic control - LC-MS/MS data

The global type 2 diabetes epidemic is a major health crisis and there is a critical need for innovative strategies to fight it. Although the microbiome plays important roles in the onset of insulin resistance (IR) and low-grade inflammation, the microbial compounds regulating these phenomena rem...

MetabolomicsUntargeted metabolomic profiling of HCT116 cells following DHODH and JNK inhibition

Untargeted LC-MS metabolomics was used to investigate metabolic alterations associated with DHODH inhibition and JNK signaling in colorectal cancer. The study included control, DHODH inhibitor treated, JNK inhibitor treated, and combined treatment groups, with pooled quality control samples for a...

MetabolomicsSARS-CoV-2 ORF7a Drives Mitochondrial Dysfunction via PDK4 Activation and Complex I Inhibition

SARS-CoV-2 reprograms host metabolism to promote viral replication and evade immune responses. While infection is known to impair mitochondrial function and enhance glycolysis, the role of viral accessory proteins in these alterations remains unclear. Here, we investigate the metabolic impact of ...

MetabolomicsNiacin restriction with NAMPT-inhibition is synthetic lethal to neuroendocrine carcinoma (Cell NAMPTi treatment)

NAMPT plays a major role in NAD biosynthesis in many cancers and is an attractive potential cancer target. However, factors dictating therapeutic efficacy of NAMPT inhibitors (NAMPTi) are unclear. We report that neuroendocrine phenotypes predict lung and prostate carcinoma vulnerability to NAMPTi...

MetabolomicsEnterotoxigenic Bacteroides fragilis exacerbates alcoholic liver disease progression through kynurenine mediated AMPK signaling inhibition and retinoic acid depletion

Abstract Background & Aims: Alcoholic liver disease (ALD) pathogenesis involves gut microbiota dysbiosis, but specific pathobionts and mechanisms remain unclear. This study investigated the role of patient-derived enterotoxigenic Bacteroides fragilis (ETBF) in ALD progression and its underlyi...
