Exercise Delays Brain Ageing Through Muscle‐Brain Crosstalk

Cell Proliferation, EarlyView.
This graphical abstract illustrates the reciprocal crosstalk between the brain and peripheral organs, highlighting the profound impact of exercise on brain health through systemic interactions. It underscores how exercise influences the brain via signals from various organs and, conversely, how the brain modulates functions of peripheral organs.

A signal transduction blind spot: the function of adenylyl cyclase transmembrane domains

The FEBS Journal, EarlyView.
Transmembrane adenylyl cyclases (tmACs) are essential for synthesising the universal second messenger cyclic AMP. All tmACs share a common topology that includes a large 12‐helix transmembrane (TM) domain. This domain accounts for ~ 35% of the coding sequence but its function is still an open question.

The onset of labor alters corticotropin-releasing hormone type 1 receptor variant expression in human myometrium : putative role of interleukin-1ß [PDF]

, 2007
CRH targets the human myometrium during pregnancy. The efficiency of CRH actions is determined by expression of functional receptors (CRH-R), which are dynamically regulated.

Allosteric modulation of protein kinase A in individuals affected by NLPD‐PKA, a neurodegenerative disease in which the PRKAR1B L50R variant is expressed

The FEBS Journal, EarlyView.
In healthy neurons, Protein kinase A (PKA) forms a tetrameric holoenzyme enabling precise allosteric regulation. We characterized a novel neurodegenerative disease, neuronal loss, and parkinsonism driven by PRKAR1B mutation (NLPD‐PKA), demonstrating disrupted holoenzyme assembly, reduced cooperativity, and increased catalytic subunit nuclear ...

The Enigmatic Canal-Associated Neurons Regulate Caenorhabditis elegans Larval Development Through a cAMP Signaling Pathway. [PDF]

, 2019
Caenorhabditis elegans larval development requires the function of the two Canal-Associated Neurons (CANs): killing the CANs by laser microsurgery or disrupting their development by mutating the gene ceh-10 results in early larval arrest. How these cells

Regulation of cAMP responses by the G12/13 pathway converges on adenylyl cyclase VII [PDF]

, 2008
Regulation of intracellular cyclic adenosine 3’, 5’-monophosphate (cAMP) by multiple pathways enables differential function of this ubiquitous second messenger in a context dependent manner.

Light Modulation of Cellular cAMP by a Small Bacterial Photoactivated Adenylyl Cyclase, bPAC, of the Soil Bacterium Beggiatoa*♦

Journal of Biological Chemistry, 2010
The recent success of channelrhodopsin in optogenetics has also caused increasing interest in enzymes that are directly activated by light. We have identified in the genome of the bacterium Beggiatoa a DNA sequence encoding an adenylyl cyclase directly ...

Expression of adenylyl cyclase isoforms in neutrophils

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2003
In the present study, we have identified the expression of adenylyl cyclase (AC) isoforms in rat neutrophils according to the mRNA analysis and the distinct mode of regulation of isoform activity. Agarose gel electrophoresis of reverse transcription-polymerase chain reaction (RT-PCR)-amplified products resulted in a single band of the expected size for

Lipid regulation of adenylyl cyclase Rv1625c from Mycobacterium tuberculosis by its membrane‐domain receptor

The FEBS Journal, EarlyView.
The adenylyl cyclase (AC) Rv1625c from M. tuberculosis is a monomeric progenitor of the nine pseudoheterodimeric mammalian AC isoforms. The hexahelical membrane anchor of Rv1625c serves as an inhibitory receptor for fatty acids, particularly oleic acid. One ligand binds into each monomer of the active Rv1625c dimer.
