Induction of dark-adaptive retinomotor movement (cell elongation) in teleost retinal cones by cyclic adenosine 3,5-monophosphate. [PDF]

open access: yes, 1982
In the teleost retina, the photoreceptors and retinal pigment epithelium (RPE) undergo extensive movements (called retinomotor movements) in response to changes in light conditions and to an endogenous circadian rhythm.

Direct Growth Graphene on Cu Nanoparticles by Chemical Vapor Deposition as Surface-Enhanced Raman Scattering Substrate for Label-Free Detection of Adenosine [PDF]

open access: yesarXiv, 2015
We present a graphene/Cu nanoparticle hybrids (G/CuNPs) system as a surface-enhanced Raman scattering (SERS) substrate for adenosine detection. The Cu nanoparticles wrapped around a monolayer graphene shell were directly synthesized on flat quartz by chemical vapor deposition in a mixture of methane and hydrogen.

Characterization of the taste receptor‐related G‐protein, α‐gustducin, in pancreatic β‐cells

open access: yesJournal of Diabetes Investigation, 2020
Aims/Introduction Taste receptors, T1rs and T2rs, and the taste‐selective G‐protein, α‐gustducin, are expressed outside the taste‐sensing system, such as enteroendocrine L cells.

AMPK Regulation of Mouse Oocyte Meiotic Resumption in Vitro [PDF]

open access: yes, 2006
We have previously shown that the adenosine analog 5-aminoimidazole-4-carboxamide-1-β-d-ribofuranoside (AICAR), an activator of AMP-activated protein kinase (AMPK), stimulates an increase in AMPK activity and induces meiotic resumption in mouse oocytes ...

Hepatic gluconeogenesis and regulatory mechanisms in lactating ruminants: A literature review

open access: yesAnimal Research and One Health, EarlyView.
phosphoenolpyruvate carboxy kinase, FBP1, and glucose‐6‐phosphatase are key rate‐limiting enzymes that determine the efficiency of gluconeogenesis. The main substrate for gluconeogenesis in the liver of ruminants is propionate, which provides more than 60% of the carbon source for gluconeogenesis.

Computational Study of Molecular Mechanisms of Caffeine Actions [PDF]

open access: yesarXiv, 2015
Caffeine (CAF) is one of the most widely and regularly consumed biologically active substances. We use computer simulation approach to the study of CAF activity by searching for its possible complexes with biopolymer fragments. The principal CAF target at physiologically important concentrations refers to adenosine receptors.

Fresh insights into the light‐induced pineal gland circadian rhythm transmission mechanism derived from mRNA and miRNA profiling

open access: yesAnimal Research and One Health, EarlyView.
Mechanisms of light in regulating the chick pineal clock. Abstract The circadian clock significantly impacts animal health and productivity, with light playing a crucial role in regulating circadian rhythms. However, the mechanisms behind light‐induced circadian transmission remain unclear, particularly in light‐sensitive avian species.
