Systematic pathway‐level analysis defines conserved transcriptional divergence between primary lung tumors and cell line models

Animal Models and Experimental Medicine, EarlyView.
Lung cancer cell lines diverge substantially from primary tumors at the transcriptional level. Using single‐sample gene set enrichment analysis and L1‐penalized feature selection across TCGA‐LUAD and CCLE‐LUAD, we identified five Hallmark pathways (E2F targets, G2M checkpoint, IFNγ response, coagulation, and EMT) that discriminated primary tumors from ...

Purine and carbohydrate availability drive Enterococcus faecalis fitness during wound and urinary tract infections

mBio
Enterococcus faecalis is commonly isolated from a variety of wound types. Despite its prevalence, the pathogenic mechanisms of E. faecalis during wound infection are poorly understood. Using a mouse wound infection model, we performed in vivo E. faecalis

E. coli genetically modified for purine nucleobase release promotes butyrate generation and colonic wound healing during DSS insult

Gut Microbes
The gut microbiota transforms energy stored as undigestible carbohydrates into a remarkable number of metabolites that fuel intestinal bacterial communities and the host tissue.

The purine path to chemotherapy

In Vitro Cellular & Developmental Biology, 1989
Antimetabolites of purine metabolism have found a use as anti-leukaemic, antiprotozoal and antiviral drugs, in immunosuppression and transplantation, and in gout and hyperuricemia. Their mechanisms of action are reviewed.

Effect of Cyclic Heat Exposure on the Growth Performance and Metabolism of Broilers Fed Palm Kernel Meal

Animal Research and One Health, EarlyView.
The aim of our study is to evaluate the interaction between HS and the incorporation of PKM in broiler chicken diets, as well as its effect on growth performance and metabolism. Based on the results obtained, PKM supplementation failed to mitigate the adverse effects of heat stress in broiler chickens. ABSTRACT The aim of this study was to evaluate the

Disulfide Bond–Modified Proteomics Reveals the Effects of Riboflavin on Protein Folding Dynamics

Animal Research and One Health, EarlyView.
Riboflavin deficiency impairs oxidative protein folding, causing ER misfolded protein accumulation, CHOP activation, and apoptosis, revealing a role of riboflavin in proteostasis. ABSTRACT Riboflavin is a crucial micronutrient essential for maintaining cellular homeostasis, acting as an important precursor for flavoproteins that utilize flavin ...

Purine and pyrimidine synthesis differently affect the strength of the inoculum effect for aminoglycoside and β-lactam antibiotics

Microbiology Spectrum
The inoculum effect has been observed for nearly all antibiotics and bacterial species. However, explanations accounting for its occurrence and strength are lacking.

Inosine‐Triphosphate‐Pyrophosphatase Activity as a Potential Predictor of Methotrexate Remission in Juvenile Idiopathic Arthritis

Arthritis &Rheumatology, EarlyView.
Objective Methotrexate (MTX) is the first‐line therapy for juvenile idiopathic arthritis (JIA), but up to 40% of patients do not respond to it. Low inosine triphosphate pyrophosphatase (ITPA) activity has been associated with reduced clinical remission. We investigated the role and underlying mechanisms of ITPA in vitro. Methods ITPA enzymatic activity

Tissue‐Specific and Spatially Dependent Metabolic Signatures Perturbed by Injury in Male and Female Mice

Arthritis &Rheumatology, EarlyView.
Objective Osteoarthritis, the leading cause of disability worldwide, disproportionately affects women, yet sex remains an overlooked determinant. This disparity stems from sex‐specific differences in injury susceptibility—a major risk factor for disease.
