Roles of PDE1 in Pathological Cardiac Remodeling and Dysfunction

open access: yesJournal of Cardiovascular Development and Disease, 2018
Pathological cardiac hypertrophy and dysfunction is a response to various stress stimuli and can result in reduced cardiac output and heart failure. Cyclic nucleotide signaling regulates several cardiac functions including contractility, remodeling, and ...

The camp analogue, dbcAMP can stimulate rabbit reproductive functions: I. Effect on ovarian folliculogenesis, ovulation and embryo production [PDF]

open access: yesActa Veterinaria, 2012
The aim of our study was to examine the influence of administration of N6,2’-dibutyryladenosine 3’5’-cyclic monophosphate (dbcAMP), a cAMP agonist, on ovarian folliculogenesis and atresia, as well as on reproductive efficiency in rabbits, whose ...

Functional Analysis of the Expanded Phosphodiesterase Gene Family in Toxoplasma gondii Tachyzoites

open access: yesmSphere, 2022
Toxoplasma motility is both activated and suppressed by 3′,5′-cyclic nucleotide signaling. Cyclic GMP (cGMP) signaling through Toxoplasma gondii protein kinase G (TgPKG) activates motility, whereas cyclic AMP (cAMP) signaling through TgPKAc1 inhibits ...

Cyclic nucleotide-gated channels: structural basis of ligand efficacy and allosteric modulation [PDF]

open access: yes, 1997
Most working proteins, including metabolic enzymes, transcription regulators, and membrane receptors, transporters, and ion channels, share the property of allosteric coupling. The term 'allosteric' means that these proteins mediate indirect interactions

The role of cyclic nucleotide on fetal and neonantal erythropoiesis [PDF]

open access: yes, 1974
For the purpose to reveal the changes in stimulatory effect of dibutyryl-cyclic- AMP on erythropoiesis during ontogenetic development, the author studied syntheses of DNA, RNA and protein of erythroid cells in fetal liver, neonatal and adult bone marrows

Effect of knocking down the insulin receptor on mouse rod responses. [PDF]

open access: yes, 2015
Previous experiments have shown that the insulin receptor (IR) is expressed in mammalian rods and contributes to the protection of photoreceptors during bright-light exposure.

Real-time visualization of conformational changes within single MloK1 cyclic nucleotide-modulated channels

open access: yesNature Communications, 2016
Some ion channels are modulated by binding of cyclic nucleotide to a cyclic nucleotide-binding domain. Here, the authors use high-speed atomic force microscopy to directly monitor the conformational changes induced by ligand binding to a cyclic ...

Nucleotides as Bacterial Second Messengers

open access: yesMolecules, 2023
In addition to comprising monomers of nucleic acids, nucleotides have signaling functions and act as second messengers in both prokaryotic and eukaryotic cells. The most common example is cyclic AMP (cAMP).

Kinesin's backsteps under mechanical load [PDF]

open access: yes, 2009
Kinesins move processively toward the plus end of microtubules by hydrolyzing ATP for each step. From an enzymatic perspective, the mechanism of mechanical motion coupled to the nucleotide chemistry is often well explained using a single-loop cyclic ...

A case-control study of rheumatoid arthritis identifies an associated single nucleotide polymorphism in the NCF4 gene, supporting a role for the NADPH-oxidase complex in autoimmunity [PDF]

open access: yes, 2007
Rheumatoid arthritis (RA) is a chronic inflammatory disease with a heritability of 60%. Genetic contributions to RA are made by multiple genes, but only a few gene associations have yet been confirmed.
