MetabolomicsHypusination Orchestrates the Antimicrobial Response of Macrophages
Innate responses of myeloid cells defend against pathogenic bacteria via inducible effectors. Deoxyhypusine synthase (DHPS) catalyzes the transfer of the N-moiety of spermidine to the lysine-50 residue of eukaryotic translation initiation factor 5A (EIF5A) to form the amino acid hypusine. Hypusinate...

MetabolomicsCTH exacerbates Helicobacter pylori immunopathogenesis by promoting macrophage metabolic remodeling and activation
Macrophages play a crucial role in the inflammatory response to the human stomach pathogen Helicobacter pylori, which infects half of the world's population and causes gastric cancer. Recent studies have highlighted the importance of macrophage immunometabolism in their activation state and function...

TranscriptomicsMicroarray skeletal muscle PPARbeta overexpressing mice
This experiment was conducted to identify target genes of the peroxisome proliferator-activated receptor beta (PPARb) in skeletal muscle of transgenic mice that overexpressed PPARb. The following abstract from the submitted manuscript describes the major findings of this work. The Nuclear Receptor ...

TranscriptomicsTranscriptional Response to Iron Limitation in Pelagibacter ubique
We investigated the gene expression responses of Candidatus Pelagibacter ubique cultures to iron limitation. Differential expression was observed for genes in iron acquisition and incorporation operons. SfuC in particular was 16 times higher in iron-limited cultures and encodes a periplasmic iron-bi...

TranscriptomicsMelanoma cell culture phenotypes
Recent trials with MAPK inhibitors have shown promising results in many patients with metastatic melanoma; however, nearly all responding patients experience disease relapse. We describe here how melanoma cells respond to MAPK inhibition in a phenotype-specific manner, suggesting that slow cycling i...

MetabolomicsOrnithine Decarboxylase in Gastric Epithelial Cells Promotes the Immunopathogenesis of Helicobacter pylori Infection

Colonization by H. pylori is associated with a wide range of gastric diseases, ranging from superficial gastritis to more severe pathologies, including intestinal metaplasia and adenocarcinoma. The interplay of the host response and the pathogen affect the outcome of disease. One major component ...

TranscriptomicsMicroRNA expression profiling of skeletal muscle from PPARalpha- and PPARbeta-overexpressing mice
This experiment was conducted to identify target microRNAs of the peroxisome proliferator-activated receptor (PPAR) in skeletal muscle of transgenic mice that overexpressed PPARalpha or PPARbeta. We have recently demonstrated that skeletal muscle-specific PPARb transgenic (MCK-PPARb) mice exhibit i...

MetabolomicsBacterial Pathogens Hijack the Innate Immune Response by Activation of the Reverse Transsulfuration Pathway

The reverse transsulfuration pathway is the major route for the metabolism of sulfur-containing amino acids. The role of this metabolic pathway in macrophage response and function is unknown. We show that the enzyme cystathionine γ-lyase (CTH) is induced in macrophages infected with pathogenic ba...
