Activity of Cyclic AMP Phosphodiesterases and Adenylyl Cyclase in Peripheral Nerve after Crush and Permanent Transection Injuries [PDF]

open access: yes, 1998
Recent studies demonstrate that cAMP levels are tightly controlled during demyelination and remyelination in Schwann cells as cAMP decreases to 8–10% of normal following both sciatic nerve crush or permanent transection injury and only begins to increase

Lycium barbarum polysaccharides enhance testicular spermatogenesis in d‐galactose‐induced aging rats via calcium signaling

open access: yesAndrology, EarlyView.
Abstract Background Lycium barbarum polysaccharide (LBP) has long been recognized as having a wide range of beneficial properties for improving proliferation. However, the protective effects and specific mechanisms of d‐galactose‐induced testicular dysfunction in reproductively senescent rats are not fully understood.

Outcomes following exposure to drug interactions with ibrutinib in patients with chronic lymphocytic leukaemia

open access: yesBritish Journal of Haematology, EarlyView.
Summary Ibrutinib is metabolized by cytochrome P450 3A (CYP3A) and poses challenges with drug interactions. We conducted a population‐based cohort study of Ontario residents aged ≥66 years who initiated ibrutinib for chronic lymphocytic leukaemia (CLL) to evaluate the frequency of potential drug interactions involving moderate/strong CYP3A inhibitors ...

Isozyme variation in four species of the Simulium perflavum species group (Diptera: Simuliidae) from the Brazilian Amazon

open access: yesGenetics and Molecular Biology, 2003
Electrophoretic studies of isozymes were done with four closely related species of the Simulium perflavum species group (Diptera: Simuliidade) in the Brazilian Amazon, using last-instar larvae collected in the field.

IA‐0130, a novel 3‐(1,3‐diarylallylidene)oxindole derivative, alleviates ovarian cancer via inhibiting IL‐6/gp130/STAT3 signalling

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Dysregulation of the IL‐6/glycoprotein 130(gp130)/STAT3 signalling axis is implicated in several human diseases, particularly cancer. Notably, gp130, a single transducer of this signalling axis, is a target for ovarian cancer treatment. However, data regarding small‐molecule inhibitors of gp130 are lacking. Therefore, we aimed to

Diversity and genetic struture in cajá tree (spondias mombin l.) populations in northeastern Brazil Diversidade e estrutura genética de populações em cajazeira (spondias mombin l.) no nordeste do Brasil

open access: yesRevista Brasileira de Fruticultura, 2009
Spondias mombin L. is a fruit tree from the American continent from the Anacardiaceae family. In Brazil it is common in different vegetation types but is more frequent in the Atlantic and Amazonian rainforests. It is economically important because of its

Role of Histone Deacetylase and Inhibitors in Cardiovascular Diseases

open access: yesCell Proliferation, EarlyView.
HDACs play an important role in the occurrence and development of cardiovascular diseases, such as myocardial hypertrophy, hypertension, and atherosclerosis. HDAC inhibitors have broad prospects for the treatment of CVD, and different HDAC subtypes can act through different mechanisms.

Mutant-based model of two independent pathways for carotenoid-mediated chloroplast biogenesis in Arabidopsis embryos [PDF]

open access: yes, 2019
Chloroplasts are essential for autonomous plant growth, and their biogenesis is a complex process requiring both plastid and nuclear genome. One of the essential factors required for chloroplast biogenesis are carotenoids.

Posttranslational modifications of phosphodiesterase type 4 enzymes represent novel points for therapeutic targeting

open access: yesThe FEBS Journal, EarlyView.
Enzymes from the phosphodiesterase type 4 family (PDE4) coordinate physiological events driven by the cyclic AMP s(cAMP) signaling pathway by tightly controlling cAMP dynamics in many cell types. Key to this strict regulation is the myriad of posttranslational modifications that alter PDE4 activity, cellular location, and binding partner selection ...
