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.

Subcellular localization of retinoids, retinoid-binding proteins, and acyl-CoA:retinol acyltransferase in rat liver

open access: yesJournal of Lipid Research, 1987
Studies were conducted to define the subcellular localization of endogenous retinoids (vitamin A), retinoid-binding proteins, and acyl-CoA:retinol acyltransferase (ARAT) in liver and to determine whether their distributions were affected by hepatic ...

Bioengineered Exosome‐Loaded Immunomodulatory Bioadhesive Spray Reverses Liver Fibrosis and Metabolic Dysfunction That Triggers Beneficial Gut‐Liver Crosstalk in Chronic Fatty Liver Disease

open access: yesAdvanced Science, EarlyView.
Umbilical cord stem cell‐derived exosomes encapsulated in an immunomodulatory bioadhesive hydrogel spray enable localized therapy, sustained vesicle delivery, macrophage polarization, suppress systemic inflammation, and mitigate glucose and insulin homeostasis impairments in MAFLD.

METTL7A Downregulation Drives SLC1A5‐Mediated Glutamine Competition to Promote Tumor Proliferation and Suppress CD8+ T Cell Immunity in Gastric Cancer

open access: yesAdvanced Science, EarlyView.
GC cells enhance glutamine accumulation by upregulating SLC1A5 expression. This upregulation not only boosts GC cell proliferation, but also outcompetes CD8+ T cells for glutamine and suppresses their antitumor immunity. Mechanistically, METTL7A deficiency in GC induces SLC1A5 overexpression via an m6A‐dependent pathway and N‐glycosylation ...

RPB4 and pathogenesis of diabetes [PDF]

open access: yes, 2007
Obesity is an important risk factor for a number of chronic diseases that impose a huge burden on individuals and society. Recently it has become clear that adipose tissue-secreted products may play a significant role in mediating many obesity-related ...

Effects of dietary retinoic acid on cellular retinol- and retinoic acid-binding protein levels in various rat tissues.

open access: yesJournal of Lipid Research, 1990
A study was conducted to explore the effects of retinoic acid, fed to retinol-deficient rats, on the tissue distribution and levels of cellular retinol-binding protein (CRBP) and cellular retinoic acid-binding protein (CRABP).

Repurposing a Small Molecule Plant Hormone as a Tunable ON‐Switch for CAR‐T Cell Immunotherapy

open access: yesAdvanced Science, EarlyView.
By engineering a receptor system integrating the plant auxin receptor AFB1 with its co‐receptor IAA7, we enable ligand‐dependent interactions triggered by the plant hormone auxins. This design allows rapid, reversible, and dose‐dependent T cell activation, resulting in potent cytotoxicity against B‐cell lymphoma in vitro and in vivo.

Retinol-Binding Protein Interferes with Transthyretin-Mediated β‑Amyloid Aggregation Inhibition

open access: yes, 2018
β-Amyloid (Aβ) aggregation is causally linked to Alzheimer’s disease. On the basis of in vitro and transgenic animal studies, transthyretin (TTR) is hypothesized to provide neuroprotection against Aβ toxicity by binding to Aβ and inhibiting its ...

Colchicine inhibition of retinol-binding protein secretion by rat liver.

open access: yesJournal of Lipid Research, 1980
Studies were conducted to explore the effects of colchicine on the secretion and metabolism of retinol-binding protein (RBP) by the liver. In the vitamin A-deficient rat, the rate of secretion of RBP from the liver into the serum is greatly reduced, and ...

Molecular basis for the interaction of cellular retinol binding protein 2 (CRBP2) with nonretinoid ligands

open access: yesJournal of Lipid Research, 2021
Present in the small intestine, cellular retinol binding protein 2 (CRBP2) plays an important role in the uptake, transport, and metabolism of dietary retinoids.
