A short review on structure and role of cyclic-3',5'-adenosine monophosphate-specific phosphodiesterase 4 as a treatment tool

open access: yesJournal of Research in Pharmacy Practice, 2015
Cyclic nucleotide phosphodiesterases (PDEs) are known as a super-family of enzymes which catalyze the metabolism of the intracellular cyclic nucleotides, cyclic-3',5'-adenosine monophosphate (cAMP), and cyclic-3',5'-guanosine monophosphate that are ...

Adenosine A2A-Receptor Stimulation Inhibits Lipopolysaccharide-Induced Interleukin-18 Production in Monocytes

open access: yesJournal of Pharmacological Sciences, 2007
Adenosine inhibited interleukin (IL)-18 production in lipopolysaccharide (LPS)-stimulated monocytes. The action of adenosine was antagonized by an adenosine A2A-receptor (A2AR) antagonist and was mimicked by an A2AR agonist, suggesting that the ...

Photobiomodulation‑Engineered Extracellular Vesicles Enhance Neural Differentiation via UFL1‑Mediated UFMylation in Spinal Cord Injury

open access: yesAdvanced Science, EarlyView.
Photobiomodulated microglia release engineered extracellular vesicles that deliver UFL1 to the injured spinal cord. UFL1 competitively binds p53 with MDM2, inhibiting p53 ubiquitination and stabilizing p53 signaling. This dual mechanism simultaneously promotes anti‐inflammatory microglial polarization and directs neural stem cell differentiation toward

The Construction and Application of a New Screening Method for Phosphodiesterase Inhibitors

open access: yesBiosensors
Phosphodiesterases (PDEs), a superfamily of enzymes that hydrolyze cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP), are recognized as a therapeutic target for various diseases.

Cyclic adenosine monophosphate and cyclic guanosine monophosphate variations during isometric tetanus in frog sartorius muscle

open access: yes, 1982
Tetanic stimulation at different temperatures (5 and 20 °C) of the frog sartorius muscle results in an increase of cyclic guanosine monophosphate (cGMP) directly correlated to the tension developed.

Caffeine affects the biological responses of human hematopoietic cells of myeloid lineage via downregulation of the mTOR pathway and xanthine oxidase activity [PDF]

open access: yes, 2015
Correction of human myeloid cell function is crucial for the prevention of inflammatory and allergic reactions as well as leukaemia progression. Caffeine, a naturally occurring food component, is known to display anti-inflammatory effects which have ...

The Cancer Cell Metabolic Reprogramming Remodels the Tumor Microenvironment: Molecular Mechanisms and Therapeutic Strategies

open access: yesAdvanced Science, EarlyView.
This review elucidates how cancer cell metabolic reprogramming—across glucose, lipid, amino acid, and nucleotide pathways—remodels the tumor microenvironment to suppress anti‐tumor immunity and promote immune escape. Targeting these metabolic axes offers promising strategies to overcome immunotherapy resistance and enhance cancer treatment.

Glucose and Glutamine Deprivation Promotes Breast Cancer Lung Metastasis via BRD4‐Dependent Enhancer Activation

open access: yesAdvanced Science, EarlyView.
To model a nutrient‐restricted tumor microenvironment, breast cancer cells were adapted to low glucose and glutamine levels. In the adapted cells, BRD4‐driven enhancer activation increases pro‐invasive EDN1 expression, facilitated by ATF3/c‐JUN and reinforced by enhancer RNA.
