Nutrient addition modifies phosphatase activities along an altitudinal gradient in a tropical montane forest in Southern Ecuador

open access: yesFrontiers in Earth Science, 2016
Atmospheric nutrient deposition and climate change are expected to endanger the diversity of tropical forest ecosystems. Nitrogen (N) deposition might influence nutrient fluxes beyond the N cycle by a concomitant increased demand for other nutritional ...

Use of the KlADH3 promoter for the quantitative production of the murine PDE5A isoforms in the yeast Kluyveromyces lactis [PDF]

open access: yes, 2017
Background: Phosphodiesterases (PDE) are a superfamily of enzymes that hydrolyse cyclic nucleotides (cAMP/ cGMP), signal molecules in transduction pathways regulating crucial aspects of cell life.

Phosphodiesterase Inhibitors [PDF]

open access: yesInternational Cardiovascular Forum Journal, 2019
Phosphodiesterases (PDEs) comprise a superfamily with 11 subfamilies. Within these families, more than 40 isoforms are expressed. Phosphodiesterase-3 inhibitors (PDE3i) are used as inotrope/vasodilators for acute heart failure (HF), and PDE5i for pulmonary hypertension and erectile dysfunction.

Development and Structural Characterization of UTE‐156, a Covalent Inhibitor of the VCP/p97 AAA+ ATPase

open access: yesAdvanced Science, EarlyView.
The AAA+ ATPase Valosin‐containing protein (VCP/p97) regulates protein homeostasis by unfolding ubiquitinated substrates. Here, we describe UTE‐156, a novel irreversible covalent inhibitor that modifies Cys522 in the D2 ATPase motor domain. Although its pharmacochemical limitations preclude immediate therapeutic use, UTE‐156 serves as a valuable ...

The cAMP-signaling cancers: Clinically-divergent disorders with a common central pathway

open access: yesFrontiers in Endocrinology, 2022
The cAMP-signaling cancers, which are defined by functionally-significant somatic mutations in one or more elements of the cAMP signaling pathway, have an unexpectedly wide range of cell origins, clinical manifestations, and potential therapeutic options.

Tadalafil modulates aromatase activity and androgen receptor expression in a human osteoblastic cell in vitro model [PDF]

open access: yes, 2016
Purpose Phosphodiesterase type-5 inhibitor (PDE5i) tadalafil administration in men with erectile dysfunction is associated with increased testosterone/estradiol ratio, leading to hypothesize a potential increased effect of androgen action on target ...

Mammalian Glycerophosphodiester Phosphodiesterases [PDF]

open access: yesBioscience, Biotechnology, and Biochemistry, 2007
Bacterial glycerophosphodiester phosphodiesterases (GP-PDEs), GlpQ and UgpQ, are well-characterized periplasmic and cytosolic proteins that play critical roles in the hydrolysis of deacylated glycerophospholipids to glycerol phosphate and alcohol, which are utilized as major sources of carbon and phosphate.

An Implantable Scaffold Sequentially Releasing STING Agonist and B7‐H3 Antibody for Bone Metastasis Immunotherapy

open access: yesAdvanced Science, EarlyView.
We developed an implantable dual‐drug depot using GelMA for bone metastasis treatment, co‐delivering MSA‐2 and αB7‐H3‐loaded CaCO3 microparticles. Sustained release from GelMA scaffold enables MSA‐2 to activate STING signaling and enhance T‐cell infiltration and activation, while sequentially released αB7‐H3 blocks MSA‐2‐induced B7‐H3 upregulation ...

DNA single-strand break repair and spinocerebellar ataxia with axonal neuropathy-1 [PDF]

open access: yes, 2007
DNA single-strand breaks (SSBs) are the commonest DNA lesions arising spontaneously in cells, and if not repaired may block transcription or may be converted into potentially lethal/clastogenic DNA double-strand breaks (DSBs).

Phosphodiesterases and preeclampsia

open access: yesMedical Hypotheses, 2017
Antagonizing vasodilation has been considered one of the potential mechanisms underlying the pathophysiology of preeclampsia. Phosphodiesterases hydrolyze cGMP, interfering with the action of nitric oxide on vascular smooth muscle, thus causing vasoconstriction.
