Reversal of age-related learning deficiency by the vertebrate PACAP and IGF-1 in a novel invertebrate model of aging: the pond snail (Lymnaea Stagnalis) [PDF]

open access: yes, 2014
With the increase of life span, nonpathological age-related memory decline is affecting an increasing number of people. However, there is evidence that age-associated memory impairment only suspends, rather than irreversibly extinguishes, the intrinsic ...

NPR1 Promotes Lipid Droplet Lipolysis to Enhance Mitochondrial Oxidative Phosphorylation and Fuel Gastric Cancer Metastasis

open access: yesAdvanced Science, EarlyView.
NPR1 induces lipolysis of stored lipid droplet and enhances mitochondrial oxidative phosphorylation to fuel gastric cancer metastasis. Specifically, NPR1‐mediated activation of PKG directly phosphorylates and activates HSL at Ser855 and Ser951, thereby driving lipolytic processes.

Portopulmonary hypertension practice patterns after liver transplantation

open access: yesLiver Transplantation, EarlyView., 2022
Abstract Portopulmonary hypertension (POPH) is a type of pulmonary arterial hypertension occurring exclusively in those with portal hypertensive liver disease. Liver transplantation (LT) can significantly improve outcomes. Current guidelines counsel against immediate adjustments to targeted therapy after LT and suggest routine echocardiography as ...

PACAP and migraine headache: immunomodulation of neural circuits in autonomic ganglia and brain parenchyma. [PDF]

open access: yes, 2018
The discovery that intravenous (IV) infusions of the neuropeptide PACAP-38 (pituitary adenylyl cyclase activating peptide-38) induced delayed migraine-like headaches in a large majority of migraine patients has resulted in considerable excitement in ...

A Two‐Component Pseudo‐Icosahedral Protein Nanocompartment with Variable Shell Composition and Irregular Tiling

open access: yesAdvanced Science, EarlyView.
The structure and assembly principles of a two‐component encapsulin nanocompartment shell are reported. The two‐component protein compartment self‐assembles from two distinct HK97‐fold shell proteins into a pseudo‐icosahedral protein shell with variable composition and irregular tiling.

Adenylyl Cyclases in Mycobacteria [PDF]

open access: yesJournal of Life Science, 2011
Adenylyl cyclase (AC) catalyzes the formation of cyclic AMP (cAMP) from ATP. The cAMP produced by AC serves as a secondary messenger in a variety of signal transduction pathways, and controls various cellular functions in many organisms. ACs can be grouped into six classes based on their primary amino acid sequences. Eukaryotes and mycobacteria contain

Intestinal Clock Promotes Cognitive Memory Through Adenosine Signaling

open access: yesAdvanced Science, EarlyView.
The intestinal clock controls the expression of an adenosine enzyme that modulates systemic adenosine level and A1R signaling in the hippocampus, and in turn, cognitive function involving long‐term potentiation and BDNF‐dependent synaptic changes.

Construction of a pathway to C50-ε-carotene.

open access: yesPLoS ONE, 2019
Substrate tolerance of bacterial cyclases has been demonstrated in various contexts, but little is known about that of plant cyclases. Here, we tested two plant ε-cyclases to convert C50-lycopene, which we previously established by rounds of directed ...

Mechanism of actin-dependent activation of nucleotidyl cyclase toxins from bacterial human pathogens

open access: yesNature Communications, 2021
The nucleotidyl cyclase toxin exoenzyme Y (ExoY), which is secreted by the human pathogens Pseudomonas aeruginosa and Vibrio vulnificus is activated by actin.
