The fluorescence yield of bound retinol in human retinolbinding protein (RBP) and irs prealbumin complex (PARBP) were found to be nearly the same and to exceed that of free retinol in petroleum ether by about 9-fold. Bovine serum albumin and P-lactoglobulin also formed strongly fluorescent water-soluble complexes with retinol. The fluorescence yield of retinol complexed with bovine serum albumi...

Background and objectives: Adipose tissue is responsible for releasing various adipokines which have been related to insulin resistance. Understanding the relationship of these adipokines to insulin resistance may help in early diagnosis and faster the development of new treatments for diabetes. The objective of this study was to determine the possible association between these adipokines (visf...

BACKGROUND Serum levels of lipocalin 2 (LCN 2) and retinol-binding protein-4 (RBP 4), increase in type 2 diabetes mellitus (T2DM). We sought to determine whether serum LCN 2 and RBP 4 change after an intervention with omega-3 fatty acids supplementation in diabetic patients. METHODS Forty-five type 2 diabetic patients from Iranian Diabetic Association in Tehran, Iran in 2013 were randomly rec...

A comparative study of the level of 4 plasma proteins in malnutrition shows that albumin has low sensitivity, transferrin has intermediate and the TBPA-RBP complex has the highes sensitivity to an alteration in the nutritional status. According to protein and/or iron deficiency, the synthesis of trnasferrin seems to be submitted to contradictory impulses which partially invalidates this test as...

Studies were conducted to explore the role of retinol in the control of the rate of synthesis of plasma retinolbinding protein (RBP) in the liver of the rat. Previous studies have shown that nutritional retinol status strongly influences RBP secretion from the liver cell. Both the in vivo relative rate of RBP synthesis and the in vitro translatable level of RBP-specific mRNA were examined...

With a more sedentary population comes growing rates of obesity and increased type 2 diabetes mellitus (T2DM) risk. Exercise generally induces positive changes in traditional T2DM risk markers such as lipids, glucose tolerance, and insulin sensitivity; however alterations in concentrations of many circulating cytokines and their respective receptors are also becoming apparent. These cytokines m...

The role of urinary retinol-binding protein (RBP) as a biomarker of CKD in proximal tubular diseases, glomerulopathies and in transplantation is well established. However, whether urinary RBP is also a biomarker of renal damage and CKD progression in general CKD is not known. In this study, we evaluated the association of urinary RBP with renal function and cardiovascular risk factors in the ba...

Vitamin A deficiency (VAD) is an important contributor to child morbidity and mortality. The prevalence of VAD, measured by retinol-binding protein (RBP) or retinol, is overestimated in populations with a high prevalence of inflammation. We aimed to quantify and adjust for the effect of inflammation on VAD prevalence in a nationally representative survey of Liberian children 6 to 35 months of a...

RNA-protein interactions play a major role in gene regulation. Although many techniques to analyze RNA-protein interactions have been developed, noteworthy challenges such as determining the RNA sequences that bind RNA-binding proteins (RBPs) remain unsolved. Here, we describe a novel technique using a 4-thio-uridine-incorporated RNA pool to identify the RBP-binding consensus sequences for RBPs...

Serum vitamin A homeostasis was studied in rats with nonfiltering kidneys prepared by ligation of renal arteries. Within 1-2 h of acute renal failure, the serum retinol level increased by 11-73% and was maintained for at least 4 h. More than 90% of the increase in serum retinol was associated with retinol in the retinol binding protein-transthyretin (RBP-TTR) complex. The activities of acyl-CoA...
