Rho GTPases in Skeletal Muscle Development and Homeostasis
Cells, 2021 Rho guanosine triphosphate hydrolases (GTPases) are molecular switches that cycle between an inactive guanosine diphosphate (GDP)-bound and an active guanosine triphosphate (GTP)-bound state during signal transduction. As such, they regulate a wide range

Guanosine: a Neuromodulator with Therapeutic Potential in Brain Disorders
Aging and Disease, 2016 Guanosine is a purine nucleoside with important functions in cell metabolism and a protective role in response to degenerative diseases or injury. The past decade has seen major advances in identifying the modulatory role of extracellular action of ...

Guanosine nucleotides regulate B2 kinin receptor affinity of agonists but not of antagonists: Discussion of a model proposing receptor precoupling to G protein [PDF]
, 2000 The effect of nucleotides on binding of the B2 kinin (BK) receptor agonist {[}H-3]BK and the antagonist {[}H-3]NPC17731 to particulate fractions of human foreskin fibroblasts was studied.

An Information Theoretical Analysis of Kinase Activated Phosphorylation Dephosphorylation Cycle [PDF]
IEEE Transactions on NanoBioscience, Volume 11, Issue 3, pp. 289 -
295 (2012), 2011 Signal transduction, the information processing mechanism in biological cells, is carried out by a network of biochemical reactions. The dynamics of driven biochemical reactions can be studied in terms of nonequilibrium statistical physics. Such systems may also be studied in terms of Shannon's information theory.

Guanosine and its modified derivatives are endogenous ligands for TLR7.
International Immunology, 2016 Toll-like receptor (TLR) 7and 8 were considered to recognize single-strand RNA (ssRNA) from viruses. Although these receptors also respond to synthetic small chemical ligands, such as CL075 and R848, it remains to be determined whether these receptors ...

Hybridization Properties of RNA Containing 8-Methoxyguanosine and 8-Benzyloxyguanosine. [PDF]
PLoS ONE, 2015 Modified nucleobase analogues can serve as powerful tools for changing physicochemical and biological properties of DNA or RNA. Guanosine derivatives containing bulky substituents at 8 position are known to adopt syn conformation of N-glycoside bond.

A thermodynamic paradigm for solution demixing inspired by nuclear transport in living cells [PDF]
Phys. Rev. Lett. 118, 158101 (2017), 2016 Living cells display a remarkable capacity to compartmentalize their functional biochemistry. A particularly fascinating example is the cell nucleus. Exchange of macromolecules between the nucleus and the surrounding cytoplasm does not involve traversing a lipid bilayer membrane.
