Salvage enzymes in nucleotide biosynthesis [PDF]

open access: yes, 2007
Balanced pools of deoxyribonucleoside triphosphates (dNTPs), the building blocks of DNA, and ribonucleoside triphosphates (NTPs), the precursors of RNA, are crucial for a controlled cell proliferation.

Dual Action of Dipyridamole in Experimental Rheumatoid Arthritis: Suppression of Joint Inflammation and Upregulation of Muscle Anabolism via Adenosine and AMPK pathways

open access: yesArthritis &Rheumatology, Accepted Article.
Introduction Rheumatoid sarcopenia, characterized by the progressive loss of skeletal muscle mass and function, is a frequent comorbidity in rheumatoid arthritis (RA), linked to prolonged, severe systemic inflammation. Purinergic signaling (adenosine, AMP, and ATP) plays a crucial role in inflammation, myogenesis, and muscle hypertrophy.

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

open access: yesArthritis &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

The cystic fibrosis transmembrane recruiter the alter ego of CFTR as a multi-kinase anchor [PDF]

open access: yes, 2007
This review focuses on a newly discovered interaction between protein kinases involved in cellular energetics, a process that may be disturbed in cystic fibrosis for unknown reasons.

Autophosphorylation of nucleoside diphosphate kinase from Myxococcus xanthus [PDF]

open access: yesJournal of Bacteriology, 1993
The nucleoside diphosphate kinase (NDP kinase) from Myxococcus xanthus has been purified to homogeneity and crystallized (J. Munoz-Dorado, M. Inouye, and S. Inouye, J. Biol. Chem. 265:2702-2706, 1990). In the presence of ATP, the NDP kinase was autophosphorylated.

ProTides for Antiviral Activity Beyond Liver Cells

open access: yesChemistry – A European Journal, EarlyView.
A strategy for obtaining prodrugs of antiviral nucleotides with broad tissue activity is presented that relies on cycloalkyl or cycloalkylalkyl esters, improving uptake and esterase cleavage, and producing nanomolar inhibitors in kidney, colon, and lung cells.

Substrate Induced Structural and Dynamics Changes in Human Phosphomevalonate Iinase and Implications for Mechanism [PDF]

open access: yes, 2009
Phosphomevalonate kinase (PMK) catalyzes an essential step in the mevalonate pathway, which is the only pathway for synthesis of isoprenoids and steroids in humans.

Nucleoside diphosphate kinase/Nm23 and Epstein–Barr virus [PDF]

open access: yesMolecular and Cellular Biochemistry, 2009
Nm23-H1 was discovered as the first metastasis suppressor gene about 20 years ago. Since then, extensive work has contributed to understanding its role in various cellular signaling pathways. Its association with a range of human cancers as well as its ability to regulate cell cycle and suppress metastasis has been explored. We have determined that the

The potential for biased signalling in the P2Y receptor family of GPCRs

open access: yesBritish Journal of Pharmacology, EarlyView.
The purinergic receptor family is primarily activated by nucleotides, and contains members of both the G protein coupled‐receptor (GPCR) superfamily (P1 and P2Y) and ligand‐gated ion channels (P2X). The P2Y receptors are widely expressed in the human body, and given the ubiquitous nature of nucleotides, purinergic signalling is involved with a plethora
