Differential calcium signaling by cone specific guanylate cyclase-activating proteins from the zebrafish retina.

open access: yesPLoS ONE, 2011
Zebrafish express in their retina a higher number of guanylate cyclase-activating proteins (zGCAPs) than mammalians pointing to more complex guanylate cyclase signaling systems.

No evidence for oncogenic mutations in guanine nucleotide-binding proteins of human adrenocortical neoplasms [PDF]

open access: yes, 1933
G-Proteins are membrane-bound heterotrimeric polypeptides that couple receptor signals to second messenger systems such as cAMP. Recently, point mutations at 2 codons of the highly preserved alpha-chain of Gs, the adenyl cyclase-stimulating G-protein ...

SPARCL1 and NT‐proBNP as biomarkers of right ventricular‐to‐pulmonary artery uncoupling in pulmonary hypertension

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1416-1426, April 2025.
Abstract Aims SPARCL1 was recently identified as a biomarker of right ventricular (RV) maladaptation in patients with pulmonary hypertension (PH), and N‐terminal pro‐brain natriuretic protein (NT‐proBNP) is an established biomarker of RV failure in PH. The present study investigated whether NT‐proBNP and SPARCL1 concentrations are associated with load ...

BIOTIC STRESS IMPACT ON ACTIVITY OF VARIOUS FORMS OF ADENYLATE CYCLASE IN ORGANELLES OF POTATO PLANT CELLS [PDF]

open access: yesJournal of Stress Physiology & Biochemistry, 2006
Notwithstanding significant interest towards study of adenylate cyclase plant signal system, there is still no complete picture of functioning and regulation mechanisms of this signal system in plants under biotic stress. With this in view, our study was

The Oxidosqualene Cyclase from the Oomycete Saprolegnia Parasitica Synthesizes Lanosterol as a Single Product

open access: yesFrontiers in Microbiology, 2016
The first committed step of sterol biosynthesis is the cyclisation of 2,3-oxidosqualene to form either lanosterol or cycloartenol. This is catalyzed by an oxidosqualene cyclase.

Growth Hormone (GH)-Releasing Peptide Stimulation of GH Release from Human Somatotroph Adenoma Cells: Interaction with GH-Releasing Hormone, Thyrotropin- Releasing Hormone, and Octreotide. [PDF]

open access: yes, 1994
The synthetic hexapeptide GH-releasing peptide (GHRP; His-D-Trp-Ala-Trp-D-Phe-Lys-NH2) specifically stimulates GH secretion in humans in vivo and in animals in vitro and in vivo via a still unknown receptor and mechanism.

Ring Formation in Sesquiterpene Synthesis: Biomimetic vs. Non‐Biomimetic Strategies

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A short review of cyclase enzyme‐mediated ring formation in sesquiterpene biosynthesis is presented as a prelude to six case studies examining the merits and demerits of biomimetic vs. non‐biomimetic strategies for carbocyclisation in the total synthesis of this iconic natural product class.

Riociguat for the treatment of chronic thromboembolic pulmonary hypertension. [PDF]

open access: yes, 2013
BACKGROUND: Riociguat, a member of a new class of compounds (soluble guanylate cyclase stimulators), has been shown in previous clinical studies to be beneficial in the treatment of chronic thromboembolic pulmonary hypertension. METHODS: In this phase 3,
