Multi-Functional OCT Enables Longitudinal Study of Retinal Changes in a VLDLR Knockout Mouse Model. [PDF]
PLoS ONE, 2016 We present a multi-functional optical coherence tomography (OCT) imaging approach to study retinal changes in the very-low-density-lipoprotein-receptor (VLDLR) knockout mouse model with a threefold contrast.

The effects of dietary carotenoid supplementation and retinal carotenoid accumulation on vision-mediated foraging in the house finch. [PDF]
PLoS ONE, 2011 BACKGROUND: For many bird species, vision is the primary sensory modality used to locate and assess food items. The health and spectral sensitivities of the avian visual system are influenced by diet-derived carotenoid pigments that accumulate in the ...

Visual adaptation of opsin genes to the aquatic environment in sea snakes
BMC Evolutionary Biology, 2020 Background Evolutionary transitions from terrestrial to aquatic life history cause drastic changes in sensory systems. Indeed, the drastic changes in vision have been reported in many aquatic amniotes, convergently.

Accelerated evolution of dim-light vision-related arrestin in deep-diving amniotes
Frontiers in Ecology and Evolution, 2022 Arrestins are key molecules involved in the signaling of light-sensation initiated by visual pigments in retinal photoreceptor cells. Vertebrate photoreceptor cells have two types of arrestins, rod arrestin, which is encoded by SAG and is expressed in ...

A new mouse model for retinal degeneration due to Fam161a deficiency
Scientific Reports, 2021 FAM161A mutations are the most common cause of inherited retinal degenerations in Israel. We generated a knockout (KO) mouse model, Fam161a tm1b/tm1b , lacking the major exon #3 which was replaced by a construct that include LacZ under the expression of ...

Structure and Conformation of the Carotenoids in Human Retinal Macular Pigment. [PDF]
PLoS ONE, 2015 Human retinal macular pigment (MP) is formed by the carotenoids lutein and zeaxanthin (including the isomer meso-zeaxanthin). MP has several functions in improving visual performance and protecting against the damaging effects of light, and MP levels are

Vitamin A deficiency affects gene expression in the Drosophila melanogaster head
G3: Genes, Genomes, Genetics, 2021 Insufficient dietary intake of vitamin A causes various human diseases. For instance, chronic vitamin A deprivation causes blindness, slow growth, impaired immunity, and an increased risk of mortality in children.
