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

Adss1–HDAC3 Interaction: A Novel Mechanism for Epigenetic Regulation of Metabolism in Adipose Tissue

iNew Medicine, EarlyView.
ABSTRACT Obesity and its related metabolic disorders have emerged as global public health challenges with underlying mechanisms involving an imbalance between energy storage and expenditure in the adipose tissue. In recent years, with the deepening research on adipose tissue metabolism, the cross talk between metabolic enzymes and epigenetic regulation

Some aspects of purinergic signaling in the ventricular system of porcine brain

Acta Veterinaria Scandinavica, 2011
Background Numerous signaling pathways function in the brain ventricular system, including the most important - GABAergic, glutaminergic and dopaminergic signaling. Purinergic signalization system - comprising nucleotide receptors, nucleotidases, ATP and

Changes in Medicago truncatula seed proteome along the rehydration–dehydration cycle highlight new players in the genotoxic stress response

Frontiers in Plant Science, 2023
IntroductionSeveral molecular aspects underlying the seed response to priming and the resulting vigor profile are still poorly understood. Mechanisms involved in genome maintenance deserve attention since the balance between stimulation of germination ...

Uric Acid in Metabolic Dysfunction‐Associated Steatotic Liver Disease

Portal Hypertension &Cirrhosis, EarlyView.
MASLD is the most prevalent chronic liver disease worldwide, yet effective pharmacological treatments remain limited. Hyperuricemia is now recognized as a key driver of hepatic steatosis, inflammation, and fibrosis, with elevated serum uric acid levels independently predicting hepatocellular carcinoma and liver‐related mortality.

A journey into the regulatory secrets of the de novo purine nucleotide biosynthesis

Frontiers in Pharmacology
De novo purine nucleotide biosynthesis (DNPNB) consists of sequential reactions that are majorly conserved in living organisms. Several regulation events take place to maintain physiological concentrations of adenylate and guanylate nucleotides in cells ...

Calcium‐induced conversion of adenine nucleotides to inosine monophosphate in human red cells.

The Journal of Physiology, 1988
1. When inosine‐fed human red cells are permeabilized to calcium by exposure to the ionophore A23187, progressively larger proportions of the cell population become irreversibly depleted of ATP as calcium influx is increased (Brown & Lew, 1983; García‐Sancho & Lew, 1988b).

Novel approaches for drug development against chronic primary pain: A systematic review

British Journal of Pharmacology, EarlyView.
Abstract Chronic primary pain (CPP) persisting for more than 3 months, associated with significant emotional distress without any known underlying cause, is an unmet medical need. Traditional or adjuvant analgesics do not provide satisfactory pain relief for a great proportion of these patients.

Plant organelle C‐to‐U RNA editing factors can operate successfully in yeast (Saccharomyces cerevisiae) as an easily amenable eukaryotic system for their functional analysis

The FEBS Journal, EarlyView.
Plant‐type pentatricopeptide repeat proteins capable of C‐to‐U RNA editing perform faithfully when expressed in a new heterologous system, the yeast Saccharomyces cerevisiae. They were tested with constitutive and inducible expression and with a set of different solubility tags. PPR56, PPR65, and PPR78 from P.

Untargeted Metabolomic and Lipidomic Profiles of Gingival Crevicular Fluid in the Context of Periodontitis

Journal of Clinical Periodontology, EarlyView.
ABSTRACT Aim(s) This cross‐sectional clinical study aimed to explore the untargeted metabolomic and lipidomic profiles in gingival crevicular fluid (GCF) obtained from healthy individuals and patients with periodontitis. Materials and Methods GCF was collected from 17 periodontally healthy and 19 periodontitis patients.
