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 ...

Requirement of Drosophila NF1 for activation of adenylyl cyclase by PACAP38-like neuropeptides

, 1997
The human neurofibromatosis type 1 (NF1) tumor suppressor protein functions as a Ras-specific guanosine triphosphatase-activating protein, but the identity of Ras- mediated pathways modulated by NF1 remains unknown.

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 ...

The regulation of the cAMP signalling pathway in the human pathogenic fungus Paracoccidioides brasiliensis [PDF]

, 2008
Paracoccidioides brasiliensis (Pb) is the causative agent of the disease Paracoccioidomycosis (PCM), which is one of the most prevalent systemic mycoses in Latin Amercia (Borges-Walmsley et al., 2002). P.

LepR‐Lineage Cells Represent the Main Target of the Nociceptive CGRP Pathway in White Adipose Tissue Browning

Advanced Science, EarlyView.
Regulation of WAT Browning and UCP1 Expression in LepR‐MSCs of Inguinal WAT by Nociceptive CGRP and Sympathetic Nervous System (SNS) Noradrenaline (NE). ABSTRACT Sympathetic innervation regulates white adipose tissue (WAT) browning; however, the roles of nociceptive neurons and their associated target cells remain unknown.

ADENYLYL CYCLASE ASSAYS TO MEASURE MACROPHAGE CHEMOTACTIC PROTEIN-1 RECEPTOR FUNCTION

Iranian Journal of Allergy, Asthma and Immunology, 2000
Adenylyl cyclase is a membrane-bound enzyme that catalyzes the conversion of ATP to cAMP. The inhibition of adenylyl cyclase was carried out by measuring the ability of the macrophage chemotactic protein-1 to inhibit the torskolin-induced enzyme activity.

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

Evidence for functional pre-coupled complexes of receptor heteromers and adenylyl cyclase

Nature Communications, 2018
It is unclear whether GPCRs, G proteins and adenylyl cyclase (AC) associate through random collisions or defined pre-coupling mechanisms. Using a peptide-based approach, the authors show that heteromers of adenosine A2A and dopamine D2 receptors form pre-

Resveratrol enhances A1 and hinders A2A adenosine receptors signaling in both HeLa and SH-SY5Y cells: Potential mechanism of its antitumoral action

Frontiers in Endocrinology, 2022
Despite great efforts, effective treatment against cancer has not yet been found. However, natural compounds such as the polyphenol resveratrol have emerged as promising preventive agent in cancer therapy.

Regulation of Adenylyl Cyclase by Membrane Potential [PDF]

Journal of Biological Chemistry, 1998
Mammalian adenylyl cyclases possess 12 transmembrane-spanning domains and bear a superficial resemblance to certain classes of ion channels. Some evidence suggests that bacterial and sea urchin sperm adenylyl cyclases can be regulated by membrane depolarization. In the present study, we explored the effect of altering membrane potential on the adenylyl
