Synergistic Regulation of Pigment Cell Precursors’ Differentiation and Migration by ednrb1a and ednrb2 in Nile Tilapia

Cells
The evolutionary loss of ednrb2 in specific vertebrate lineages, such as mammals and cypriniform fish, raises fundamental questions about its functional necessity and potential redundancy or synergy with paralogous endothelin receptors in pigment cell ...

Radiological Evaluation of Huntington’s Disease: A Case Report [PDF]

Journal of Clinical and Diagnostic Research
Huntington’s Disease (HD) is a rare neurodegenerative condition inherited in an autosomal dominant pattern, where Gamma Amino Butyric Acid-ergic (GABAergic) neurons in the basal ganglia progressively deteriorate.

The intermolecular dimer potential for guanine

The Journal of Chemical Physics, 2017
The ab initio intermolecular potential of guanine has been developed with the help of a combination of symmetry-adapted perturbation theory and density functional theory (DFT). The resulting potential has been globally optimized to locate the guanine cluster structures up to tetramers.

Synthetic Routes to N-9 Alkylated 8-Oxoguanines; Weak Inhibitors of the Human DNA Glycosylase OGG1

Molecules, 2015
The human 8-oxoguanine DNA glycosylase OGG1 is involved in base excision repair (BER), one of several DNA repair mechanisms that may counteract the effects of chemo- and radiation therapy for the treatment of cancer. We envisage that potent inhibitors of

Guanine Deaminase Stimulates Ultraviolet-induced Keratinocyte Senescence in Seborrhoeic Keratosis via Guanine Metabolites

Acta Dermato-Venereologica, 2020
DNA damage and oxidative stress play a critical role in photoageing. Seborrhoeic keratosis (SK) affects sunlight-exposed sites in aged individuals. This study examined the mechanism of photoageing in SK.

Partial Replacement of Fish Meal with Fish Scale Meal Enhances Body Color Brightness and Iridophore Development in Koi (Cyprinus carpio var. koi)

Animals
Body color brightness is a key determinant of ornamental value in koi, yet nutritional strategies targeting structural coloration mediated by iridophores remain underexplored.

Intermediate filaments spatially organize intracellular nanostructures to produce the bright structural blue of ribbontail stingrays across ontogeny

Frontiers in Cell and Developmental Biology
In animals, pigments but also nanostructures determine skin coloration, and many shades are produced by combining both mechanisms. Recently, we discovered a new mechanism for blue coloration in the ribbontail stingray Taeniura lymma, a species with ...
