PRDM16 is necessary for sensory neuronal development and differentiation in the trigeminal ganglion

Developmental Dynamics, EarlyView.
Abstract Background Cranial neural crest cells (cNCC) generate craniofacial cartilage, bone, and peripheral neurons and glia, and birth defects arise when the cartilage/neuronal/glial progenitors fail to differentiate. PRDM16 is a transcriptional regulator containing both zinc‐finger and SET domains, implicated in craniofacial development and orofacial

Post‐ovipositional staging series of the foveate, gold‐dust day gecko, Phelsuma laticauda (Gekkota: Squamata)

Developmental Dynamics, EarlyView.
Abstract Background Disorders affecting the fovea, a specialized pit in the human retina necessary for high acuity vision, represent a significant healthcare burden across the globe. Degenerative diseases (e.g., macular degeneration) and developmental conditions (e.g., albinism and aniridia) affecting the fovea can lead to irreversible, central vision ...

Development of a Zebrafish Embryo‐Based Test System for Thyroid Hormone System Disruption: 3Rs in Ecotoxicological Research

Environmental Toxicology and Chemistry, EarlyView.
Abstract There is increasing concern regarding pollutants disrupting the vertebrate thyroid hormone (TH) system, which is crucial for development. Thus, identification of TH system–disrupting chemicals (THSDCs) is an important requirement in the Organisation for Economic Co‐operation and Development (OECD) testing framework.

Lipid second messengers and related enzymes in vertebrate rod outer segments

Journal of Lipid Research, 2010
Rod outer segments (ROSs) are specialized light-sensitive organelles in vertebrate photoreceptor cells. Lipids in ROS are of considerable importance, not only in providing an adequate environment for efficient phototransduction, but also in originating ...

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 ...

Bio‐inspired vision: From principle, material architectures to system‐level integration

FlexMat, EarlyView.
This review introduces the development and mechanism of electronic and ionic bio‐inspired vision devices respectively. Then, it explores the impact of structure on bio‐inspired visual performance from the scale of intrinsic materials and device. Finally, it concludes that only by combining advanced software and technology can more complex vision ...

Evolution of vertebrate retinal photoreception [PDF]

, 2016
Recent findings shed light on the steps underlying the evolution of vertebrate photoreceptors and retina. Vertebrate ciliary photoreceptors are not as wholly distinct from invertebrate rhabdomeric photoreceptors as is sometimes thought.

The 3D organisation of mitochondria in primate photoreceptors

Scientific Reports, 2021
Vertebrate photoreceptors contain large numbers of closely-packed mitochondria which sustain the high metabolic demands of these cells. These mitochondria populations are dynamic and undergo fusion and fission events. This activity serves to maintain the

Oxidative Damage, Energy Imbalance, and Behavioral Disruptions in Girardia tigrina Exposed to Treated Sewage Effluents

Environmental Toxicology, EarlyView.
ABSTRACT This study assessed the ecotoxicological effects of treated sewage on the freshwater planarian Girardia tigrina, integrating biochemical, energetic, and behavioral biomarkers. Planarians were exposed for 48 h to different concentrations of treated sewage (12.5%, 25%, 50%, and 100%) and compared to controls using commercial water and water from

Müller cells are living optical fibers in the vertebrate retina [PDF]

, 2007
Although biological cells are mostly transparent, they are phase objects that differ in shape and refractive index. Any image that is projected through layers of randomly oriented cells will normally be distorted by refraction, reflection, and scattering.
