Human DCTPP1 (dCTP pyrophosphatase 1), also known as XTP3-transactivated protein A, belongs to MazG-like nucleoside triphosphate pyrophosphatase (NTP-PPase) superfamily. Being a newly identified pyrophosphatase, its relevance to tumorigenesis and the mechanisms are not well investigated. In the
Cytosolic inorganic pyrophosphatase plays an important role in the cellular metabolism by hydrolyzing inorganic pyrophosphate (PPi) formed as a by-product of various metabolic reactions. Inorganic pyrophosphatases are known to be associated with important functions related to the growth and
Ecto-nucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1) is a type II transmembrane glycoprotein that is involved in bone metabolism and insulin resistance, hydrolyzes 2',3'-cGAMP (a STING ligand that promotes innate immunity), and is associated with cancer stemness in breast cancers and
Breast cancer (BC) remains a significant threat to the health of women; however, the mechanism underlying the initiation and progression of BC is poorly understood. We analyzed data from the Gene Expression Omnibus database and The Cancer Genome Atlas datasets to identify differentially expressed
Cancer stem cells (CSCs) have been identified in various types of cancer; however, the mechanisms by which cells acquire CSC properties such as drug resistance and tumour seeding ability are not fully understood. Here, we identified microRNA-27b (miR-27b) as a key regulator for the generation of a
Multidrug resistance (MDR) is a major obstacle to successful cancer treatment. To understand the mechanism of MDR, many cancer cell lines have been established, and various mechanisms of resistance, such as ATP-binding cassette (ABC) transporter-mediated drug efflux, have been discovered.
The appropriate supply of dNTPs is critical for cell growth and genome integrity. Here, we investigated the interrelationship between dUTP pyrophosphatase (dUTPase) and ribonucleotide reductase (RNR) in the regulation of genome stability. Our results demonstrate that reducing the expression of
Cancer cells initiate an innate immune response by synthesizing and exporting the small-molecule immunotransmitter cGAMP, which activates the anti-cancer Stimulator of Interferon Genes (STING) pathway in the host. An extracellular enzyme, ectonucleotide pyrophosphatase phosphodiesterase 1 (ENPP1),
Extracellular adenosine mediates diverse anti-inflammatory, angiogenic and vasoactive effects and becomes an important therapeutic target for cancer, which has been translated into clinical trials. This study was designed to comprehensively assess adenosine metabolism in prostate and breast cancer
In the present study, total proteins from a tissue of an infiltrating ductal carcinoma of the breast (IDCA) were compared by the two-dimensional electrophoresis (2D-PAGE) to proteins from an adjacent non-neoplastic breast tissue. Analysis of multiple gels for each sample identified nine proteins
Key nuclear processes in eukaryotes, including DNA replication, repair, and gene regulation, require extensive chromatin remodeling catalyzed by energy-consuming enzymes. It remains unclear how the ATP demands of such processes are met in response to rapid stimuli. We analyzed this question in the
Purinergic signaling cascade includes the release of endogenous ATP and other agonists by chemical and mechanical stimuli, modulation of diverse cellular functions and subsequent ectoenzymatic inactivation. Basal release of extracellular purines and its physiological relevance remain controversial.
