The Oxytocin Receptor in Spermatozoa May Originate From Both Spermatogenesis and Epididymal Maturation, and Regulates Capacitation

Andrology, EarlyView.
Abstract Background The oxytocin receptor (OR) is a G‐protein‐coupled receptor recently identified in human spermatozoa, whose origin and role in sperm physiology remain unknown. Objectives In this study, using the pig as a model, we examine the presence of the OR in ejaculated spermatozoa through immunofluorescence and immunoblotting, and investigate ...

Rhodopsin Signaling and Organization in Heterozygote Rhodopsin Knockout Mice [PDF]

Journal of Biological Chemistry, 2004
Rhodopsin (Rho) resides within internal membrane structures called disc membranes that are found in the rod outer segments (ROS) of photoreceptors in the retina. Rho expression is essential for formation of ROS, which are absent in knockout Rho-/- mice.

The potential for biased signalling in the P2Y receptor family of GPCRs

British Journal of Pharmacology, EarlyView.
The purinergic receptor family is primarily activated by nucleotides, and contains members of both the G protein coupled‐receptor (GPCR) superfamily (P1 and P2Y) and ligand‐gated ion channels (P2X). The P2Y receptors are widely expressed in the human body, and given the ubiquitous nature of nucleotides, purinergic signalling is involved with a plethora

Visual Function Assessment in Geographic Atrophy: A Review

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Geographic atrophy (GA) causes significant vision impairment and reduction in vision‐related quality of life. Fundus autofluorescence (FAF) is the gold standard of structural assessment of GA but is a surrogate marker for vision loss, which can be assessed by tests of visual function and functional vision.

Docosahexaenoic acid promotes photoreceptor differentiation without altering Crx expression [PDF]

, 2006
PURPOSE: The precise molecular cues required for photoreceptor development are still unknown. Pax6 and Crx are essential during early retinal development and for photoreceptor differentiation, respectively.

Retinal Pigment Epitheliopathy due to Sub‐Optimal Recycling of Vitamin A (RESORVA): A Novel RDH11‐Related Phenotype

Clinical Genetics, EarlyView.
RDH11 is a minor isoenzyme that catalyses the oxidation of 11‐cis‐retinol to 11‐cis‐retinal in the retinal pigment epithelium, alongside RDH5 and RDH10. Biallelic null variants in RDH11 lead to upregulation of RDH5 and RDH10 (transcriptional adaptation), maintaining 11‐cis‐retinal bioavailability, but still causing Retinal Pigment Epitheliopathy due to

A Multi-Scale–Multi-Stable Model for the Rhodopsin Photocycle

Molecules, 2014
We report a multi-scale simulation study of the photocycle of the rhodopsins. The quasi-atomistic representation (“united atoms” UA) of retinal is combined with a minimalist coarse grained (CG, one-bead-per amino acid) representation of the protein, in a

Binding of rhodopsin and rhodopsin analogues to transducin, rhodopsin kinase and arrestin-1

World Journal of Biological Chemistry, 2014
Laparoscopic surgery is the main treatment method for patients with gastrointestinal malignant tumors. Although laparoscopic surgery is minimally invasive, its tool stimulation and pneumoperitoneum pressure often cause strong stress reactions in patients. On the other hand, gastrointestinal surgery can cause stronger pain in patients, compared to other

Dietary anthocyanidin pelargonidin activates G protein‐coupled receptor 35

The FEBS Journal, EarlyView.
Pelargonidin, a red‐fruit‐derived anthocyanidin, was newly identified as a dietary agonist of GPR35, a metabolite‐sensing GPCR implicated in anti‐inflammation. Through screening of dietary compounds, pelargonidin emerged as a potent GPR35 agonist, attenuating inflammation in human intestinal cells.
