Role of G-Substrate in the NO/cGMP/PKG Signal Transduction Pathway for Photic Entrainment of the Hamster Circadian Clock

open access: yesASN Neuro, 2021
The mammalian circadian clock at the hypothalamic suprachiasmatic nuclei (SCN) entrains biological rhythms to the 24-h cyclic environment, by encoding light-dark transitions in SCN neurons.

cAMP-Signalling Regulates Gametocyte-Infected Erythrocyte Deformability Required for Malaria Parasite Transmission. [PDF]

open access: yes, 2015
Blocking Plasmodium falciparum transmission to mosquitoes has been designated a strategic objective in the global agenda of malaria elimination. Transmission is ensured by gametocyte-infected erythrocytes (GIE) that sequester in the bone marrow and at ...

Sequence‐ and Docking‐Site‐Dependent Contributions to Multi‐Site Phosphorylation of an Intrinsically Disordered MAPK Substrate

open access: yesAdvanced Science, EarlyView.
Real‐time NMR spectroscopy is used to study JNK1‐dependent phosphorylation of the intrinsically disordered substrate JIP1, revealing eleven phosphosites with distinct phosphorylation efficiencies. The site‐specific phosphorylation rates are shown to be determined by both the sequence position of the phosphosites relative to the two kinase docking site ...

Phosphodiesterase 5 inhibitors: are they cardioprotective? [PDF]

open access: yesCardiovascular Research, 2009
A growing body of animal studies provides evidence for potential cardioprotective effects of inhibitors of the enzyme phosphodiesterase isoform 5. Infarct size reduction by administration of phosphodiesterase 5 inhibitors was described in various experimental models of ischaemia and reperfusion.

MdDSK2a‐Like‐MdMTA Module Functions in Apple Cold Response via Regulating ROS Detoxification and Cell Wall Deposition

open access: yesAdvanced Science, EarlyView.
Under cold stress, MdDSK2a‐like is degraded via the 26S proteasome pathway, thereby alleviating the degradation of MdMTA induced by the 26S proteasome and autophagy pathways mediated by MdDSK2a‐like. The accumulated MdMTA increases the m6A levels of cold‐responsive genes, thereby contributing to increased ROS detoxification, deposition of cell wall, as

Activation of protein kinase A stimulates the progesterone-induced calcium influx in human sperm exposed to the phosphodiesterase inhibitor papaverine.

open access: yesJournal of Andrology, 2008
Progesterone induces a fast transient calcium influx in human sperm though the activation of nongenomic receptors. During sperm capacitation, a complex process required for sperm to be able to fertilize the egg, the calcium influx induced by progesterone

Evolution of Phosphodiesterase-5 Inhibitors

open access: yesThe World Journal of Men's Health, 2015
After the launch of sildenafil citrate (Viagra®), the last great invention of the 20th century, in 1998, oral phosphodiesterase (PDE)-5 inhibitors were established as first-line treatment for erectile dysfunction (ED), representing a paradigm shift in the diagnosis and treatment of ED [1].

Erectile dysfunction and its management in patients with diabetes mellitus [PDF]

open access: yes, 2015
Diabetes can be described as a syndrome of multiple closely related conditions induced by a chronic state of hyperglycaemia resulting from defective insulin secretion, insulin action or both.

Genetic Impacts on the Structure and Mechanics of Cellulose Made by Bacteria

open access: yesAdvanced Science, EarlyView.
A genetic mutation in a protease of a cellulose‐overproducing evolved bacterium significantly affects the proteome, structure, and mechanical properties of bio‐fabricated cellulose pellicles. By overexpressing synthase proteins that build the cellulose‐forming biological machinery of the cell, the evolved bacterium generates dense, stiff, and strong ...

GC–MS Analysis and In Vivo and Ex Vivo Antidiarrheal and Antispasmodic Effects of the Methanolic Extract of Acacia nilotica

open access: yesMolecules, 2022
This present study evaluated and rationalized the medicinal use of the fruit part of Acacia nilotica methanolic extract. The phytochemicals were detected using gas chromatography–mass spectrometry (GC–MS) while the in vivo antidiarrheal test was done ...
