Spatiotemporally Precise Rheumatoid Arthritis Therapy via a Triple‐Locked Cascaded Nanoplatform With Dual‐Channel Self‐Reporting

Advanced Science, EarlyView.
An orthogonally programmable nanotheranostic (MB@YW NPs) enables precision therapy for rheumatoid arthritis. A triple‐locked (pH, HOCl/ONOO−, light) independently drives the release of methotrexate and sulfasalazine. Trackable by dual‐channel fluorescence, this coordinated drug delivery remodels the inflammatory microenvironment to markedly suppress ...

Soluble adenylyl cyclase: A novel player in cardiac hypertrophy induced by isoprenaline or pressure overload. [PDF]

PLoS ONE, 2018
In contrast to the membrane bound adenylyl cyclases, the soluble adenylyl cyclase (sAC) is activated by bicarbonate and divalent ions including calcium.

Melatonin Mitigates Doxorubicin‐Induced Cardiotoxicity by Targeting the USP18/PKM2 Axis Without Compromising Antitumor Efficacy

Advanced Science, EarlyView.
Melatonin engages MT1/MT2 receptors to suppress STAT1‐driven USP18 upregulation, thereby redirecting PKM2 ubiquitination from K33‐linked autophagic degradation toward K27‐linked nuclear translocation. This prevents PKM2‐mediated proinflammatory gene expression in the heart, alleviating doxorubicin‐induced cardiotoxicity without compromising antitumor ...

cAMP-dependent cell differentiation triggered by activated CRHR1 in hippocampal neuronal cells

Scientific Reports, 2017
Corticotropin-releasing hormone receptor 1 (CRHR1) activates the atypical soluble adenylyl cyclase (sAC) in addition to transmembrane adenylyl cyclases (tmACs).

Astrocytic Calcium and cAMP in Neurodegenerative Diseases

Frontiers in Cellular Neuroscience, 2022
It is commonly accepted that the role of astrocytes exceeds far beyond neuronal scaffold and energy supply. Their unique morphological and functional features have recently brough much attention as it became evident that they play a fundamental role in ...

Adenylyl cyclases (ACs) in GtoPdb v.2025.3 [PDF]

Adenylyl cyclase, E.C. 4.6.1.1, converts ATP to cyclic AMP and pyrophosphate. Mammalian membrane-delimited adenylyl cyclases (nomenclature as approved by the NC-IUPHAR Subcommittee on Adenylyl cyclases [11]) are typically made up of two clusters of six ...

Astrocyte SMN Restoration and Forskolin Treatment Improve SMA Synaptic Pathology

Annals of Neurology, EarlyView.
Objective Early phenotypic presentation of central afferent synapse dysfunction within patients with spinal muscular atrophy (SMA) represents a key target for therapeutic development; however, the underlying disease mechanisms remain unresolved. By further investigating motor neuron synapse and peri‐synaptic astrocyte process (PAP) defects in human SMA

Acceleration and Light-Induced Changes in Cytosolic cAMP Concentration in Euglena gracilis

Biomolecules
The second messenger cyclic AMP (cAMP) is very likely involved in phototactic as well as gravitactic behavior of the unicellular flagellate Euglena gracilis.

Somatic 'soluble' adenylyl cyclase isoforms are unaffected in Sacy tm1Lex/Sacy tm1Lex 'knockout' mice.

PLoS ONE, 2008
BackgroundMammalian Soluble adenylyl cyclase (sAC, Adcy10, or Sacy) represents a source of the second messenger cAMP distinct from the widely studied, G protein-regulated transmembrane adenylyl cyclases.

The genetically encoded tool set for investigating cAMP: more than the sum of its parts

Frontiers in Pharmacology, 2015
Intracellular fluctuations of the second messenger cyclic AMP (cAMP) are regulated with spatial and temporal precision. This regulation is supported by the sophisticated arrangement of cyclases, phosphodiesterases, anchoring proteins and receptors for ...
