Human adenovirus serotype 5 infection dysregulates cysteine, purine, and unsaturated fatty acid metabolism in fibroblasts

The FASEB Journal, Volume 39, Issue 5, 15 March 2025.
Human adenovirus serotype 5 was used to infect HEK293 fibroblasts at low MOI (0.5, 1.0, and 2.0). Infected cells were interrogated by gas chromatography time‐of‐flight mass spectrometry (GC‐TOF‐MS) at 6, 12, 24, and 36 h post‐infection. The total metabolites were evaluated using an untargeted analysis of primary carbons. The results indicate a decrease

Purine nucleoside phosphorylase activity in acute lymphoblastic leukemia [PDF]

Blood, 1980
Purine nucleoside phosphorylase (PNP) activity has been measured in the lymphoblasts of 22 patients with acute lymphoblastic leukemia (ALL) and correlated with routine immunologic cell surface markers. Fourteen of the 22 patients were considered to have non-T, non-B-cell ALL; 8 patients had T-cell disease.

Abiotic Ribonucleoside Formation in Aqueous Microdroplets: Mechanistic Exploration, Acidity, and Electric Field Effects

ChemistryEurope, Volume 3, Issue 2, March 10, 2025.
A computational investigation of the reported abiotic phosphorylation of ribose and the subsequent formation of ribonucleosides reveals that the most plausible reaction mechanism involves the protonation of ribose, followed by carbocation formation and an SN2 substitution step.

Computational quantum chemistry, molecular docking, and ADMET predictions of imidazole alkaloids of Pilocarpus microphyllus with schistosomicidal properties.

PLoS ONE, 2018
Schistosomiasis affects million people and its control is widely dependent on a single drug, praziquantel. Computational chemistry has led to the development of new tools that predict molecular properties related to pharmacological potential.

CD147 Mediates the Metabolic Reprogramming of Cancer Associated Fibroblasts Induced by EVs Released by Differentiating Cancer Stem Cells

Journal of Extracellular Biology, Volume 4, Issue 3, March 2025.
ABSTRACT Several reports have demonstrated that CD147, an N‐glycosylated protein that is exchanged by cells in soluble form or through small extracellular vesicles (sEVs), can promote cancer progression. However, its activity related to EVs in colorectal cancer (CRC) is still not fully understood.

Partial Purine Nucleoside Phosphorylase Deficiency [PDF]

Journal of Clinical Investigation, 1978
Immune function in two brothers with a deficiency of purine nucleoside phosphorylase was evaluated in vivo and in vitro. Both patients had a history of recurrent infections and profound lymphopenia. Studies of cell-mediated immunity revealed an absence of delayed cutaneous reactivity to a number of antigens, including dinitrochlorobenzene, and ...

Targeted enzyme prodrug therapy for metastatic prostate cancer – a comparative study of L-methioninase, purine nucleoside phosphorylase, and cytosine deaminase

Journal of Biomedical Sciences, 2014
BackgroundEnzyme prodrug therapy shows promise for the treatment of solid tumors, but current approaches lack effective/safe delivery strategies. To address this, we previously developed three enzyme-containing fusion proteins targeted via annexin V to ...

Guanylate Kinase 1 Deficiency: A Novel and Potentially Treatable Mitochondrial DNA Depletion/Deletions Disease

Annals of Neurology, Volume 96, Issue 6, Page 1209-1224, December 2024.
Objective Mitochondrial DNA (mtDNA) depletion/deletions syndrome (MDDS) comprises a group of diseases caused by primary autosomal defects of mtDNA maintenance. Our objective was to study the etiology of MDDS in 4 patients who lack pathogenic variants in known genetic causes.

Purine nucleoside phosphorylase (PNP) deficiency: across-the-board severe combined immunodeficiency

Egyptian Journal of Medical Human Genetics
Background Purine nucleoside phosphorylase (PNP) deficiency is a rare, autosomal recessive, inborn error of immunity. It is characterized by progressive immune abnormalities ranging from severe combined immunodeficiency (SCID) to combined ...
