The Vitamin B₁₂-Dependent Photoreceptor AerR Relieves Photosystem Gene Repression by Extending the Interaction of CrtJ with Photosystem Promoters

mBio, 2017
Purple nonsulfur bacteria adapt their physiology to a wide variety of environmental conditions often through the control of transcription. One of the main transcription factors involved in controlling expression of the Rhodobacter capsulatus photosystem ...

Ganglion cell complex thickness in screening of hydroxychloroquine maculopathy

Delta Journal of Ophthalmology, 2020
Background Screening of early hydroxychloroquine (HCQ) maculopathy is important to prevent permanent structural and functional retinal damage. Spectral domain optical coherence tomography (SD-OCT) ultra-high-resolution imaging and speed allows better ...

Targeting the HDAC6‐Cilium Axis Ameliorates the Pathological Changes Associated with Retinopathy of Prematurity

Advanced Science, 2022
Retinopathy of prematurity (ROP) is one of the leading causes of childhood visual impairment and blindness. However, there are still very few effective pharmacological interventions for ROP.

Cholesterol homeostasis in the vertebrate retina: biology and pathobiology

Journal of Lipid Research, 2021
: Cholesterol is a quantitatively and biologically significant constituent of all mammalian cell membrane, including those that comprise the retina. Retinal cholesterol homeostasis entails the interplay between de novo synthesis, uptake, intraretinal ...

Loss of Motor Protein MYO1C Causes Rhodopsin Mislocalization and Results in Impaired Visual Function

Cells, 2021
Unconventional myosins, linked to deafness, are also proposed to play a role in retinal cell physiology. However, their direct role in photoreceptor function remains unclear.

UV Radiation Induces Specific Changes in the Carotenoid Profile of Arabidopsis thaliana

Biomolecules, 2022
UV-B and UV-A radiation are natural components of solar radiation that can cause plant stress, as well as induce a range of acclimatory responses mediated by photoreceptors.

Physiological Responses of Cucumber Seedlings to Different Supplemental Light Duration of Red and Blue LED

Frontiers in Plant Science, 2021
Normal development of plants is inhibited by inadequate light in winter in greenhouses in Northwest China. Growth lamps, using light-emitting diodes (LEDs) with red blue light (7R2B), were used to supplement daylight for 1, 2, and 3 h.

Glutamine catabolism supports amino acid biosynthesis and suppresses the integrated stress response to promote photoreceptor survival

eLife
Photoreceptor loss results in vision loss in many blinding diseases, and metabolic dysfunction underlies photoreceptor degeneration. So, exploiting photoreceptor metabolism is an attractive strategy to prevent vision loss.

Light-Induced Thiol Oxidation of Recoverin Affects Rhodopsin Desensitization

Frontiers in Molecular Neuroscience, 2019
The excessive light illumination of mammalian retina is known to induce oxidative stress and photoreceptor cell death linked to progression of age-related macular degeneration.

TRANSGENIC STRATEGY FOR IDENTIFYING SYNAPTIC CONNECTIONS IN MICE BY FLUORESCENCE COMPLEMENTATION (GRASP)

Frontiers in Molecular Neuroscience, 2012
In the "GFP reconstitution across synaptic partners" (GRASP) method, non-fluorescent fragments of GFP are expressed in two different neurons; the fragments self-assemble at synapses between the two to form a fluorophore. GRASP has proven useful
