Vitamin A transport in plasma of the non-mammalian vertebrates: isolation and partial characterization of piscine retinol-binding protein1

open access: yesJournal of Lipid Research, 1977
Studies were conducted to explore vitamin A transport in the non-mammalian vertebrates, especially Pisces, Amphibia, and Reptilia, and to isolate and partially characterize piscine retinol-binding protein.

Retinol and retinyl esters in parenchymal and nonparenchymal rat liver cell fractions after long-term administration of ethanol.

open access: yesJournal of Lipid Research, 1985
Chronic ethanol consumption reduces the liver retinoid store in man and rat. We have studied the effect of ethanol on some aspects of retinoid metabolism in parenchymal and nonparenchymal liver cells.

A Narrative Review of the Role of Transthyretin in Health and Disease

open access: yesNeurology and Therapy, 2020
Transthyretin (TTR) is a tetrameric transport protein highly conserved through vertebrate evolution and synthesized in the liver, choroid plexus, and retinal pigment epithelium. TTR transports the thyroid hormone thyroxine and the retinol-binding protein

Chaotropic Surface Arginine Correlates With Protein Corona Formation on Anti‐Fouling Biomaterial Surfaces: A Quantitative Proteomics and Protein Structure Study

open access: yesAdvanced Materials Interfaces, EarlyView.
Why do specific proteins accumulate on “non‐fouling” surfaces? Quantitative proteomics and structural analysis reveal surface‐exposed arginine as the key molecular determinant. ABSTRACT The protein corona determines the biocompatibility of medical devices, yet predicting its composition on anti‐fouling surfaces remains challenging.

A Pentaradial and Bilateral Combined Photoreception System in the Sea Cucumber is Mediated by a Blue Light‐Sensitive R‐Opsin

open access: yesAdvanced Science, EarlyView.
The sea cucumber Holothuria leucospilota detects blue and adjacent wavelengths of light via an r‐opsin with a maximum absorption at 459 nm. In the oral tentacles, papillae, and tube feet, distinct light‐sensing structures with specialized morphologies are formed, constituting a unique pentaradial and bilateral combined photoreception system.
