During pathological conditions, extracellular-5'-nucleotidase/CD73 can protect neurons by reducing the permeability of the blood brain barrier. In recent years, it has been demonstrated that CD73 can negatively contribute to the growth of gliomas; however, the function of CD73 in glioma blood
The interfascicular oligodendroglia of the rat striatum nucleus is studied in control animals and under experimentally induced brain edemas. Enzyme histochemical studies were performed. Normal oligodendrocytes show two different enzymatic distributions. While Mg2+-ATPase, TPPase, TPPase, adenylate
Adenosine is the final product of ATP metabolism, mainly derived from the action of 5'-nucleotidase cleavage of AMP. Cellular production of adenosine is greatly enhanced in inflamed tissues, ischemic tissues, and under hypoxia, where ATP is released from damaged cells. Much evidence has been
Malignant gliomas are the most common and devastating primary tumors of the adult central nervous system. Dexamethasone, a synthetic glucocorticoid, is commonly co-administered to control edema in the management of brain tumors during chemotherapy and radiotherapy. In the present study, the effect
BACKGROUND
Ecto-5'-nucleotidase (CD73) on immune cells is emerging as a critical pathway and therapeutic target in cardiovascular and autoimmune disorders.
OBJECTIVE
Here, we investigated the role of CD73 in postinfarction inflammation, cardiac repair, and remodeling in mice after reperfused
Extracellular nucleotides and nucleosides are important signaling molecules in the lung. Nucleotide and nucleoside concentrations in alveolar lining fluid are controlled by a complex network of surface ectonucleotidases. Previously, we demonstrated that influenza A/WSN/33 (H1N1) virus resulted in
Extracellular adenosine has been widely implicated in adaptive responses to hypoxia. The generation of extracellular adenosine involves phosphohydrolysis of adenine nucleotide intermediates, and is regulated by the terminal enzymatic step catalyzed by ecto-5'-nucleotidase (CD73). Guided by previous
Several biochemical and biological activities such as phospholipase A2, arginine esterase, proteolytic, L-amino acid oxidase, 5'nucleotidase, acetylcholinesterase, thrombin-like, anticoagulant, and hemorrhagic activities were determined for whole desiccated venom of Trimeresurus jerdonii. An acidic
The toxic and biological activities of four samples of Trimeresurus purpureomaculatus venom were examined. The lethality, protein composition and biological activities of the four venom samples were similar. Three of the venom samples had LD50 (i.v.) values of 0.9 micrograms/g while the fourth had a
Sulfur assimilation is an essential metabolic pathway that regulates sulfation, amino acid metabolism, nucleotide hydrolysis, and organismal homeostasis. We recently reported that mice lacking bisphosphate 3'-nucleotidase (BPNT1), a key regulator of sulfur assimilation, develop iron-deficiency
OBJECTIVE
Osmotic swelling of Müller glial cells has been suggested to contribute to retinal edema. We determined the role of adenosine signaling in the inhibition of Müller cell swelling in the murine retina.
METHODS
The size of Müller cell somata was recorded before and during perfusion of retinal
In order to determine Bothriopsis bilineata smaragdina venom (BbsV) composition, proteomic approaches were performed. Venom components were analyzed by RP-HPLC, SDS- PAGE and nano LC on line with LTQ Orbitrap XL. Results showed a total of 189 identified proteins, grouped into 11 different subgroups,
In Indian traditional medicine, various plants have been used widely as a remedy for treating snake bites. The aim of this study was to evaluate the effect of Tamarindus indica seed extract on the pharmacological as well as the enzymatic effects induced by V. russelli venom. Tamarind seed extract
Several plant extracts rich in pharmacologically active compounds have shown to antagonize venom of several species. Mangifera indica has been used against snakebite by the traditional healers. However, there is paucity of scientific data in support. In this study, we evaluated the antivenom
