Role of cyclic AMP in the control of cell-specific gene expression [PDF]

open access: yes, 1993
Genes have to be expressed in specific cell types at appropriate times of development dependent on external signals. cAMP signaling occurs in all cells, thus raising the question of how this signal transduction pattern is integrated into mechanisms ...

The many dimensions of cAMP signaling [PDF]

open access: yesProceedings of the National Academy of Sciences, 2001
In the previous issue of PNAS, Rich et al. (1) provide dynamic evidence that cAMP is produced in a restricted microdomain near the surface membrane of human embryo kidney cells transformed with adenovirus containing cyclic nucleotide-gated (CNG) channels. When activated by cAMP, the channels conduct Ca2+ into the cell, thereby offering an on-line assay

A fluorescence-based high-throughput assay for the discovery of exchange protein directly activated by cyclic AMP (EPAC) antagonists. [PDF]

open access: yesPLoS ONE, 2012
The discovery, more than ten years ago, of exchange proteins directly activated by cAMP (EPAC) as a new family of intracellular cAMP receptors revolutionized the cAMP signaling research field.

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

open access: yes, 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).

Reciprocal regulation of PKA and rac signaling [PDF]

open access: yes, 2013

Global and local missions of cAMP signaling in neural plasticity, learning and memory

open access: yesFrontiers in Pharmacology, 2015
The fruit fly Drosophila melanogaster has been a popular model to study cAMP signaling and resultant behaviors due to its powerful genetic approaches. All molecular components (AC, PDE, PKA, CREB, etc) essential for cAMP signaling have been identified in

Histamine stimulates the proliferation of small and large cholangiocytes by activation of both IP3/Ca2+ and cAMP-dependent signaling mechanisms [PDF]

open access: yes, 2012
Although large cholangiocytes exert their functions by activation of cyclic adenosine 3',5'-monophosphate (cAMP), Ca(2+)-dependent signaling regulates the function of small cholangiocytes. Histamine interacts with four receptors, H1-H4HRs.

Hedgehog and Gpr161: Regulating cAMP Signaling in the Primary Cilium

open access: yesCells, 2020
Compartmentalization of diverse types of signaling molecules contributes to the precise coordination of signal propagation. The primary cilium fulfills this function by acting as a spatiotemporally confined sensory signaling platform.

Functional selectivity of GPCR-directed drug action through location bias. [PDF]

open access: yes, 2017
G-protein-coupled receptors (GPCRs) are increasingly recognized to operate from intracellular membranes as well as the plasma membrane. The β 2 -adrenergic GPCR can activate G s -linked cyclic AMP (G s -cAMP) signaling from endosomes.

Differential Signaling Profiles of MC4R Mutations with Three Different Ligands [PDF]

open access: yes, 2020
The melanocortin 4 receptor (MC4R) is a key player in hypothalamic weight regulation and energy expenditure as part of the leptin-melanocortin pathway. Mutations in this G protein coupled receptor (GPCR) are the most common cause for monogenetic obesity,
