5$\alpha$-Cholest-8(14)-en-3$\beta$-ol-15-one is a potent inhibitor of cholesterol biosynthesis which has been found to have significant hypocholesterolemic action upon oral administration to rodents and nonhuman primates. The metabolism of (2,4-$\sp3$H) 5$\alpha$-cholest-8(14)-3n-3$\beta$-ol-15-one was studied in Chinese hamster ovary (CHO-K1) cells. The incorporation of the labeled 15-ketosterol into the cells was linear with respect to sterol concentration in the medium over the range of concentrations studied and was higher than the uptake of cholesterol. The results of detailed analyses of the lipids recovered from the cells after 6 hours of incubation with the (2,4-$\sp3$H) -15-ketosterol indicated that most of the $\sp3$H was associated with the free 15-ketosterol. Considerably smaller amounts of $\sp3$H were associated with esters of the 15-ketosterol. No conversion of the 15-ketosterol to cholesterol or other C$\sb{27}$ monohydroxysterols was observed. The labeled material with the ...

Harsh conditions cause the nonparasitic Caenorhabditis elegans larvae to enter the developmentally arrested state of dauer, which requires a decrease in the steroid hormones Δ4-dafachronic acid (Δ4-DA) and Δ7-DA to release the nuclear hormone receptor DAF-12 from its ligand-bound state. Because dauer larvae share morphological similarities with infective larvae of parasitic nematodes, and because exit from dauer in C. elegans appears to use similar signaling mechanisms as activation of infectivity in the parasitic hookworm Ancylostoma caninum, Ogawa et al. reasoned that genes involved in inducing dauer might also be present in parasitic nematodes. They first examined whether Δ4-DA, Δ7-DA, and DAF-12 were involved in inducing dauer in Pristionchus pacificus, a nonparasitic distant relative of C. elegans. Unlike C. elegans, which only enters dauer under extreme conditions, P. pacificus must enter dauer as part of its life cycle and was considered by the authors to be an intermediate between ...

The oxysterol profile of the retina suggests that all known pathways of cholesterol elimination in extraocular organs are operative in the retina and that they likely vary depending on specific cell type. However, overall oxidation to 5-cholestenoic acid appears to be the predominant mechanism for c …

New findings by researchers UT Southwestern Medical Center are accelerating efforts to eradicate worm infections that afflict a third of the worlds population.. The new findings, available online and in an upcoming issue of the Proceedings of the National Academy of Sciences, demonstrate that a biochemical system that controls development and reproduction of Caenorhabditis elegans, a common research worm, also provides the same function in several parasitic nematodes, including hookworm.. In these parasitic organisms, the activating molecule, called dafachronic acid, sends the necessary signals for the worms to mature from the stage in which they infect a host to the stage in which they start feeding on the host, which is what makes the host sick. In 2006 UT Southwestern scientists led by Dr. David Mangelsdorf, chairman of pharmacology at UT Southwestern and senior author of the new study in PNAS, had made the discovery in C elegans, a nematode about the size of a pinhead.. In the new study, ...

Meiosis-activating sterols (MAS) are substrates of SC4MOL and NSDHL in the cholesterol pathway and are important for normal organismal development. Oncogenic transformation by epidermal growth factor receptor (EGFR) or RAS increases the demand for cholesterol, suggesting a possibility for metabolic interference. To test this idea in vivo, we ablated Nsdhl in adult keratinocytes expressing KRAS(G12D). Strikingly, Nsdhl inactivation antagonized the growth of skin tumors while having little effect on normal skin. Loss of Nsdhl induced the expression of ATP-binding cassette (ABC) transporters ABCA1 and ABCG1, reduced the expression of low-density lipoprotein receptor (LDLR), decreased intracellular cholesterol, and was dependent on the liver X receptor (LXR) α. Importantly, EGFR signaling opposed LXRα effects on cholesterol homeostasis, whereas an EGFR inhibitor synergized with LXRα agonists in killing cancer cells. Inhibition of SC4MOL or NSDHL, or activation of LXRα by sterol metabolites, can ...

It is known that ceramides can influence the lateral organization in biological membranes. In particular ceramides have been shown to alter the composition of cholesterol and sphingolipid enriched nanoscopic domains, by displacing cholesterol, and forming gel phase domains with sphingomyelin. Here we have investigated how the bilayer content of ceramides and their chain length influence sterol partitioning into the membranes. The effect of ceramides with saturated chains ranging from 4 to 24 carbons in length was investigated. In addition, unsaturated 18:1- and 24:1-ceramides were also examined. The sterol partitioning into bilayer membranes was studied by measuring the distribution of cholestatrienol, a fluorescent cholesterol analogue, between methyl-beta-cyclodextrin and large unilamellar vesicle with defined lipid composition. Up to 15 mol% ceramide was added to bilayers composed of DOPC:PSM:cholesterol (3:1:1), and the effect on sterol partitioning was measured. Both at 23 and 37 degrees C ...

Increasing evidence suggests that the various components of açaí contribute to cardioprotection via mechanisms that affect cell membrane receptors, intracellular signaling pathway proteins, and the modulation of gene expression [37],. [38], [39], [40] and [41]. It has been demonstrated that flavonoids regulate the activity of the Alisertib nuclear receptor regulators of cellular lipid metabolism [42] and [43]. The present study was designed to investigate the hypocholesterolemic activity of açaí pulp using a rat model of dietary-induced hypercholesterolemia. A 2% açaí pulp dose was chosen because of its relevance to human nutrition. This dosage mimics the addition of a portion of this fruit in food [44] and selleck compound has demonstrated effects in previous studies [10], [15] and [16]. Corroborating our previous results [15], açaí supplementation improved the lipid profile in the rat. Thus, we focused on characterizing the effects that açaí pulp supplementation in the diet would ...

Cholesterol (Chol) is a crucial component of cellular membranes, but knowledge of its intracellular dynamics is scarce. Thus, it is of utmost interest to develop tools for visualization of Chol organization and dynamics in cells and tissues. For this purpose, many studies make use of fluorescently labeled Chol analogs. Unfortunately, the introduction of the label may influence the characteristics of the analog, such as its localization, interaction, and trafficking in cells; hence, it is important to get knowledge of such bias. In this report, we compared different fluorescent lipid analogs for their performance in cellular assays: 1) plasma membrane incorporation, specifically the preference for more ordered membrane environments in phase-separated giant unilamellar vesicles and giant plasma membrane vesicles; 2) cellular trafficking, specifically subcellular localization in Niemann-Pick type C disease cells; and 3) applicability in fluorescence correlation spectroscopy (FCS)-based and super-resolution

The nematode Caenorhabditis elegans is a genetically tractable model organism to investigate sterol transport. In vivo imaging of the fluorescent sterol, dehydroergosterol (DHE), is challenged by C. elegans high autofluorescence in the same spectral region as emission of DHE. We present a method to detect DHE selectively, based on its rapid bleaching kinetics compared to cellular autofluorescence. Worms were repeatedly imaged on an ultraviolet-sensitive wide field (UV-WF) microscope, and bleaching kinetics of DHE were fitted on a pixel-basis to mathematical models describing the intensity decay. Bleach-rate constants were determined for DHE in vivo and confirmed in model membranes. Using this method, we could detect enrichment of DHE in specific tissues like the nerve ring, the spermateca and oocytes. We confirm these results in C. elegans gut-granule-loss (glo) mutants with reduced autofluorescence and compare our method with three-photon excitation microscopy of sterol in selected tissues.

which he had treated once before with great success, on a larger scale, and which he also subsequently repeated. He found therein an opportunity for rich display and picturesque profusion: representing the Oriental Kings with great splendour, attended by a most brilliant suite. In the execution of this subject he succeeded in producing a great variety of new and powerful effects. Of all the compositions however dealing with this same subject, the one at Malines is perhaps the most fascinating and executed with the most loving care. We are told that Rubens himself always spoke of this work with great satisfaction. The picture gives us an impression of joy and festivity due to the beautiful harmony of its colour. The key-note is the King in the centre, clad in a magnificent red mantle, which forms a contrast with the blue garment of the Virgin.
