Cyclic guanosine monophosphate does not inhibit gonadotropin-induced activation of mitogen-activated protein kinase 3/1 in pig cumulus-oocyte complexes

open access: yesReproductive Biology and Endocrinology, 2015
BackgroundRecent results indicate a key role for cyclic guanosine monophosphate (cGMP) in the regulation of oocyte meiotic arrest in preovulatory mammalian follicles.

Liberators of NO exert a dual effect on renin secretion from isolated mouse renal juxtaglomerular cells [PDF]

open access: yes, 1993
This study aimed to examine the role of nitric oxide (NO) in the regulation of renin secretion from renal juxtaglomerular (JG) cells. Using primary cultures of mouse renal JG cells, we found that sodium nitroprusside (SNP) and 3-morpholino-sydnonimin ...

Cyclic 3'-5' guanosine monophosphate-dependent activity in Leishmania amazonensis

open access: yesMemorias do Instituto Oswaldo Cruz, 2003
Although there are some data concerning the nitric oxide and the cyclic 3'-5'guanosine monophosphate (cGMP) signaling pathway in trypanosomatids, there is no report about the cGMP-dependent enzymatic activity identification.

The role of Phosphodiesterase-1 and its natural product inhibitors in Alzheimer’s disease: A review

open access: yesFrontiers in Pharmacology, 2022
Phosphodiesterase-1 (PDE1) is a versatile enzyme that has surprisingly received considerable attention as a possible therapeutic target in Alzheimer’s disease (AD) because it maintains the homeostasis of 3ʹ,5ʹ-cyclic adenosine monophosphate (cAMP) and 3ʹ,

Photoactivation of trans diamine platinum complexes in aqueous solution and effect on reactivity towards nucleotides [PDF]

open access: yes, 2010
We show that UVA irradiation (365 nm) of the Pt-IV complex trans,trans,trans-[(PtCl2)-Cl-IV(OH)(2)(dimethylamine) (isopropylamine)] (1), induces reduction to Pt-II photoproducts.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Dietary nitrate enhances the contractile properties of human skeletal muscle [PDF]

open access: yes, 2018
Dietary nitrate, a source of nitric oxide (NO), improves the contractile properties of human muscle. We present the hypothesis that this is due to nitrosylation of the ryanodine receptor and increased NO signaling via the soluble guanyl cyclase-cyclic ...

Expanding Chemical Space of Nucleic Acid Nanoparticles for Tunable Antiviral‐Like Immunomodulatory Responses and Potent Adjuvant Activity

open access: yesAdvanced Functional Materials, EarlyView.
We introduce a nucleic acid nanoparticle (NANP) platform designed to be rrecognized by the human innate immune system in a regulated manner. By changing chemical composition while maintaining constant architectural parameters, we identify key determinants of immunorecognition enabling the rational design of NANPs with tunable immune activation profiles

Imaging of PDE2- and PDE3-Mediated cGMP-to-cAMP Cross-Talk in Cardiomyocytes

open access: yesJournal of Cardiovascular Development and Disease, 2018
Cyclic nucleotides 3′,5′-cyclic adenosine monophosphate (cAMP) and 3′,5′-cyclic guanosine monophosphate (cGMP) are important second messengers that regulate cardiovascular function and disease by acting in discrete subcellular microdomains.
