NUCLEOSIDE-DIPHOSPHATASE OF CESTODE BOTHRIOCEPHALUS SCORPII (CESTODA: BOTHRIOCEPHALIDAE)

open access: yesРоссийский паразитологический журнал, 2016
Objective of research: To study the activities and properties of nucleoside- diphosphatase (NDPase) in cestode Bothriocephalus scorpii.Materials and methods: Cestodes were homogenized with 10 vol. of extraction medium. NDPase was detected in mitochondria

Determination of total potentially available nucleosides in bovine milk [PDF]

open access: yes, 2010
Bovine colostrum and milk samples were collected from two herds over the course of the first month post-partum, pooled for each herd by stage of lactation and total potentially available nucleosides were determined.

Identification of Guanosine 5′-diphosphate as Potential Iron Mobilizer: Preventing the Hepcidin-Ferroportin Interaction and Modulating the Interleukin-6/Stat-3 Pathway

open access: yesScientific Reports, 2017
Hepcidin, a peptide hormone, is a key regulator in mammalian iron homeostasis. Increased level of hepcidin due to inflammatory conditions stimulates the ferroportin (FPN) transporter internalization, impairing the iron absorption; clinically manifested ...

Dynamics of Microtubule Growth and Catastrophe [PDF]

open access: yes, 2007
We investigate a simple model of microtubule dynamics in which a microtubule evolves by: (i) attachment of guanosine triphosphate (GTP) to its end at rate lambda, (ii) GTP converting irreversibly to guanosine diphosphate (GDP) at rate 1, and (iii ...

Expression of an atrial G-protein-activated potassium channel in Xenopus oocytes [PDF]

open access: yes, 1993
Injection of rat atrial RNA into Xenopus oocytes resulted in the expression of a guanine nucleotide binding (G) protein-activated K+ channel. Current through the channel could be activated by acetylcholine or, if RNA encoding a neuronal 5HT1A receptor ...

Transient disappearance of RAS mutant clones in plasma: A counterintuitive clinical use of EGFR inhibitors in RAS mutant metastatic colorectal cancer [PDF]

open access: yes, 2019
Genomic studies performed through liquid biopsies widely elucidated the evolutionary trajectory of RAS mutant clones under the selective pressure of EGFR inhibitors in patients with wild type RAS primary colorectal tumors. Similarly, the disappearance of

Real-Time In-Cell NMR Reveals the Intracellular Modulation of GTP-Bound Levels of RAS

open access: yesCell Reports, 2020
Summary: The small guanosine triphosphatase (GTPase) RAS serves as a molecular switch in signal transduction, and its mutation and aberrant activation are implicated in tumorigenesis.

Inhibition of Subsets of G Protein-coupled Receptors by Empty Mutants of G Protein α Subunits in Go, G11, and G16 [PDF]

open access: yes, 2000
We previously reported that the xanthine nucleotide binding Goα mutant, GoαX, inhibited the activation of Gi-coupled receptors. We constructed similar mutations in G11α and G16α and characterized their nucleotide binding and receptor interaction.

Current knowledge and recent advances in understanding metabolism of the model cyanobacterium Synechocystis sp. PCC 6803 [PDF]

open access: yes, 2020
Cyanobacteria are key organisms in the global ecosystem, useful models for studying metabolic and physiological processes conserved in photosynthetic organisms, and potential renewable platforms for production of chemicals.
