Identifizierung und Charakterisierung eines neuen Bindeproteins für zyklische Nukleotide [PDF]

open access: yes, 2007
Cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate are important intracellular messengers. Binding of cyclic nucleotides controls the activity of protein kinases, ion channels and guanine-nucleotide-exchange factors in many cells ...

Angiotensin-(1-7) and angiotensin-(1-9): function in cardiac and vascular remodeling [PDF]

open access: yes, 2014
The renin angiotensin system (RAS) is integral to cardiovascular physiology, however, dysregulation of this system largely contributes to the pathophysiology of cardiovascular disease (CVD).

Luzhou‐Flavor Baijiu Alleviates Stress‐Related Depressive‐Like Changes by NMDAR‐NO‐sGC‐cGMP Pathway

open access: yesFood Safety and Health, EarlyView.
Luzhou‐flavor baijiu (LFB) alleviates depressive‐like phenotypes in CRS‐induced mice and protects HT22 cells from corticosterone damage, with mechanisms linked to suppressing the NMDAR‐nNOS/iNOS‐NO‐sGC‐cGMP pathway. ABSTRACT Moderate alcohol consumption has been suggested to alleviate anxiety and depression; however, it remains unclear whether Luzhou ...

Nitric Oxide Inhibits Lipopolysaccharide-Induced Inducible Nitric Oxide Synthase Expression and Its Own Production Through the cGMP Signaling Pathway in Murine Microglia BV-2 Cells

open access: yesJournal of Pharmacological Sciences, 2010
The present study examined the effect of the nitric oxide (NO) donor NOC18 on lipopolysaccharide (LPS)-induced NO production to investigate a regulation mechanism of NO production by microglial cells.

Move beyond free radical theory of aging

open access: yesiMetaOmics, EarlyView.
Free radicals play a dual, dose‐dependent role in aging. Low levels activate the key sensor adenosine 5'‐monophosphate‐activated protein kinase (AMPK), promoting cell survival mechanisms like autophagy and enhancing mitochondrial health. High levels, however, push AMPK to initiate cell death pathways, such as apoptosis. This positions AMPK as a central

The efficient synthesis and purification of 2′3’- cGAMP from Escherichia coli

open access: yesFrontiers in Microbiology
Agonists of the stimulator of interferon genes (STING) pathway are being explored as potential immunotherapeutics for the treatment of cancer and as vaccine adjuvants for infectious diseases.

Nano‐plastics disrupt systemic metabolism by remodeling the bile acid–microbiota axis and driving hepatic–intestinal dysfunction

open access: yesiMeta, EarlyView.
The pervasiveness of microplastic pollution poses a growing health risk, yet its long‐term metabolic consequences remain poorly defined. Here, we exposed mice to polyethylene terephthalate nanoparticle (NP) and combined histopathology, biochemistry, metabolomics, and metagenomics to resolve their interactions.

Stimulation of Adenosine 3',5'-Monophosphate Hydrolysis by Guanosine 3',5'-Monophosphate

open access: yesJournal of Biological Chemistry, 1971
Abstract Guanosine 3',5'-monophosphate (cyclic GMP) increased the rate of adenosine 3',5'-monophosphate (cyclic AMP) hydrolysis by phosphodiesterase preparations from several tissues. Stimulation of cyclic AMP hydrolysis occurred with initial concentrations of cyclic GMP as low as 0.08 µm and was seen with particulate phosphodiesterase preparations ...

Adipose‐derived small extracellular vesicles exacerbate microvascular dysfunction in heart failure with preserved ejection fraction via mmu‐miR‐582‐3p‐mediated Rap1b suppression

open access: yesInterdisciplinary Medicine, EarlyView.
This study reveals that small extracellular vesicles (sEVs) from visceral fat compromise coronary microcirculation in a mouse model of heart failure with preserved ejection fraction (HFpEF). The SGLT2 inhibitor canagliflozin emerges as a therapeutic strategy, improving cardiac function and endothelial health.

Acidosis potentiates endothelium-dependent vasorelaxation and gap junction communication in the superior mesenteric artery. [PDF]

open access: yes, 2018
Extracellular pH is an important physiological determinant of vascular tone that is normally maintained within 7.35-7.45. Any change outside this range leads to severe pathological repercussions.
