Retinol-binding protein 4 in human obesity.
Studies in mice suggest that adipocytes serve as glucose sensors and regulate systemic glucose metabolism through release of serum retinol-binding protein 4 (RBP4). This model has not been validated in humans. RBP4 was highly expressed in isolated mature human adipocytes and secreted by differentiating human adipocytes. In contrast to the animal data, RBP4 mRNA was downregulated in subcutaneous...
متن کاملLoss of retinol-binding properties for plasma retinol-binding protein in normal human epidermis.
Terminal differentiation of the keratinocytes (cornification) has been linked to a restricted supply of retinol. Retinol is distributed to target cells by the retinol-binding protein (RBP), which circulates in the plasma in complex with transthyretin (TTR). In this study we have addressed the question of retinol delivery to the epidermis via RBP. Retinol radiobinding assays, affinity chromatogr...
متن کاملRadioimmunoassay of human plasma retinol-binding protein.
A radioimmunoassay for human plasma retinol-binding protein (RBP) has been developed utilizing a double antibody precipitation technique. RBP was purified 1500- to 2000-fold by procedures described previously. A specific anti-human RBP antiserum was prepared in rabbits by three once-weekly injections of purified RBP emulsified with Freund's adjuvant. RBP was iodinated with (131)I and the RBP-(1...
متن کاملRetinol-binding protein synthesis and secretion by the rat visceral yolk sac. Effect of retinol status.
Studies were conducted to explore in rats the role of retinol in the regulation of the synthesis and secretion of retinol-binding protein (RBP) by the visceral yolk sac compared to the liver. Previous studies have shown that in retinol deficiency, hepatic RBP secretion is specifically inhibited, whereas hepatic RBP synthesis rate is unchanged. Retinol-depleted, retinoic acid-supplemented female...
متن کاملColchicine inhibition of retinol-binding protein secretion by rat liver.
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 RBP accumulates in the liver. Injection of retinol (dispersed in a 20% Tween 40 solution) into deficient rats stimulated a rapid secretion of R...
