The molecular chaperone receptor-associated protein (RAP) is required for biosynthesis of megalin, an endocytic receptor for follicular thyroglobulin (Tg), the thyroid hormone precursor. RAP also binds to Tg itself, suggesting that it may affect Tg trafficking in various manners. To elucidate RAP function, we have studied the thyroid phenotype in RAP-knockout (RAP-KO) mice and found a reduction...

Sensory texture characteristics of cooked rice for three cultivars (74 samples) were predicted using an extrusion cell and a novel data analysis method (i. e. Spectral Stress Strain Analysis). Eight sensory texture characteristics were evaluated and force values from the instrumental tests were used in combination with Partial Least Squares regression to evaluate predictive models for each of t...

Rap is characterized by highly rhythmic delivery of words; the subtle ways in which syllables in the lyrics fit into the beats in the music lead to expressivity in rap music. Unfortunately, given a lack of notated score for the genre of rap, the task of determining the rhythm to existing rap performances must be carried out manually. In this paper, we explore a method of automatically aligning ...

MIA/CD-RAP is a small, secreted protein involved in cartilage differentiation and melanoma progression. We recently revealed that p54(nrb) acts as a mediator of MIA/CD-RAP action to promote chondrogenesis and the progression of malignant melanoma. As the molecular mechanism of MIA/CD-RAP action in cartilage has not been defined in detail until now, we aimed to understand the regulation of p54(n...

rap1/Krev-1 is a p21ras-related GTP-binding protein that has been implicated in the reversion of the ras-transformed cell phenotype. We have identified a GTPase-activating protein (GAP) specific for rap in plasma membranes isolated from differentiated HL60 cells. The rap GAP activity remained quantitatively associated with the membrane following washes with buffered 1 M LiCl containing 20 mM ED...

Receptor-associated protein (RAP) is a recognized chaperone/escort protein for members of the low density lipoprotein receptor family. In this report, we show that RAP binds to lipoprotein lipase (LPL) and may play a role in the maturation of LPL. Binding of highly purified RAP to LPL was demonstrated in vitro by solid phase assays, surface plasmon resonance, and rate zonal centrifugation. The ...

The present study aimed to investigate whether rapamycin has therapeutic potential as a treatment for alcoholic cardiomyopathy. Rats were divided into eight groups (n=7 in each group): The control group; the alcohol group; abstinence in the first week; abstinence in the third week; abstinence in the fourth week; abstinent+rapamycin (AB-RAP) until the first week (AB-RAP 1); AB-RAP until the thir...

It has been proposed that apocynin might be used in the prevention and management of atrial fibrillation (AF). The purpose of this study was to investigate the effects of apocynin on atrial electrical remodeling and oxidative stress promoted by rapid atrial pacing (RAP) in rabbits. New Zealand white rabbits were subjected to RAP with or without apocynin treatment. Serial electrophysiological st...

This study was planned to explore the capability of nanoemulsions (NEs) consisting of CapryolTM 90 and oleic acid for the delivery of rapamycin (RAP). Permeability and cytotoxicity of RAP-loaded NEs were also inspected. Pseudo-ternary phase diagrams were created with oleic acid and CapryolTM 90 (as oil phase) and four surfactants and co-surfactants at various weight ratios (Rsm). Selected NEs f...
