Effects of chlorogenic acid on carbachol-induced contraction of mouse urinary bladder

Journal of Pharmacological Sciences, 2018
Chlorogenic acid (CGA) is a polyphenol found in coffee and medicinal herbs such as Lonicera japonica. In this study, the effect of CGA-induced relaxation on carbachol (CCh)-induced contraction of mouse urinary bladder was investigated. CGA (30–300 μg/ml)

GPCR‐G protein signalling and its mutational landscape in cancer—Driver or passenger

British Journal of Pharmacology, EarlyView.
G protein‐coupled receptors (GPCRs) play a crucial role in cellular signalling, regulating various physiological processes. Abnormal expression and mutations of GPCRs have been implicated in several types of cancer, influencing tumour initiation, progression and immune response.

Distinct Spatiotemporal Distribution of Bacterial Toxin-Produced Cellular cAMP Differentially Inhibits Opsonophagocytic Signaling

Toxins, 2019
Myeloid phagocytes have evolved to rapidly recognize invading pathogens and clear them through opsonophagocytic killing. The adenylate cyclase toxin (CyaA) of Bordetella pertussis and the edema toxin (ET) of Bacillus anthracis are both calmodulin ...

Involvement of adenylyl cyclase-cAMP system on bone metabolism by osteoblasts [PDF]

, 2005
Bone metabolism is mainly regulated by two functional cells, osteoblasts and osteoclasts; the former is responsible for bone formation, and the latter for bone resorption.

The Pathogenic TSH β-Subunit Variant C105Vfs114X Causes a Modified Signaling Profile at TSHR [PDF]

, 2019
1) Background: Central congenital hypothyroidism (CCH) is a rare endocrine disorder that can be caused by mutations in the β-subunit of thyrotropin (TSHB).

Inhibition by Calcium of Mammalian Adenylyl Cyclases [PDF]

Journal of Biological Chemistry, 1999
Ca(2+) regulates mammalian adenylyl cyclases in a type-specific manner. Stimulatory regulation is moderately well understood. By contrast, even the concentration range over which Ca(2+) inhibits adenylyl cyclases AC5 and AC6 is not unambiguously defined; even less so is the mechanism of inhibition. In the present study, we compared the regulation of Ca(

Cannabinoid CB2 receptor‐mediated analgesia: mechanism‐based insights and therapeutic potential

British Journal of Pharmacology, EarlyView.
Agonists of the cannabinoid 2 (CB2) receptor have shown promise for the treatment of pain in a variety of animal models. However, despite current preclinical evidence supporting the use of CB2 agonists for pain, successful translation of findings from preclinical models to human patients is lacking.

Stimulatory effects of adenosine on prolactin secretion in the pituitary gland of the rat

Brazilian Journal of Medical and Biological Research, 2002
We investigated the effects of adenosine on prolactin (PRL) secretion from rat anterior pituitaries incubated in vitro. The administration of 5-N-methylcarboxamidoadenosine (MECA), an analog agonist that preferentially activates A2 receptors, induced a ...

Separate roles of PKA and EPAC in renal function unraveled by the optogenetic control of cAMP levels in vivo [PDF]

, 2013
Cyclic AMP (cAMP) is a ubiquitous second messenger that regulates a variety of essential processes in diverse cell types, functioning via cAMP-dependent effectors such as protein kinase A (PKA) and/or exchange proteins directly activated by cAMP (EPAC ...

A calcium-inhibited Drosophila adenylyl cyclase

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2000
Mammals possess a family of transmembrane, G-protein-responsive adenylyl cyclase isoforms (tmACs) encoded by distinct genes differing in their patterns of expression and modes of biochemical regulation. Our previous work confirmed that Drosophila melanogaster also possesses a family of tmAC isoforms defining the fly as a suitable genetic model for ...
