TDP1 deficiency sensitizes human cells to base damage via distinct topoisomerase I and PARP mechanisms with potential applications for cancer therapy [PDF]
Base damage and topoisomerase I (Top1)-linked DNA breaks are abundant forms of endogenous DNA breakage, contributing to hereditary ataxia and underlying the cytotoxicity of a wide range of anti-cancer agents.

Pre-treatment with sumatriptan for cilostazol induced headache in healthy volunteers
Background Previous studies indicate that sumatriptan is not effective when second messenger levels are high as after cilostazol provocation. Therefore, we have conducted the present study, where sumatriptan is administrated as pretreatment before cAMP ...

PDE6δ-mediated sorting of INPP5E into the cilium is determined by cargo-carrier affinity [PDF]
The phosphodiesterase 6 delta subunit (PDE6δ) shuttles several farnesylated cargos between membranes. The cargo sorting mechanism between cilia and other compartments is not understood.

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 ...

Cilostazol induced migraine does not respond to sumatriptan in a double blind trial
Background Cilostazol is an inhibitor of phosphodiesterase 3 and thus causes accumulation of cAMP. It induces migraine-like attacks in migraine patients. Whether the cilostazol model responds to sumatriptan in migraine patients and therefore is valid for

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

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

Synergistic Inhibition of Vascular Smooth Muscle Cell Migration by Phosphodiesterase 3 and Phosphodiesterase 4 Inhibitors [PDF]
Abstract—Cyclic nucleotide phosphodiesterases (PDEs) hydrolyze cAMP or cGMP and terminate their signaling. Two important families of PDEs that regulate cAMP signaling in cardiovascular tissues are the cGMP-inhibited PDEs (PDE3) and the cAMP-specific PDEs (PDE4).

Cyclic 3',5'-Nucleotide Phosphodiesterase
Abstract The activity of a mixture of a purified and a crude cyclic 3′,5′-nucleotide phosphodiesterase was greater than the summed activities of the individual preparations. The crude enzyme contained an activator, which was removed from the purified enzyme during purification.
