Early predictors of metabolic syndrome in healthy 7-9 year-olds identified -- ScienceDaily
Markers that may precede the metabolic syndrome and mechanisms that explain these relationships have yet to be identified. These mechanisms may originate in the intrauterine environment, be exacerbated in susceptible populations, such as African Americans and, be further promoted by a genetic predisposition, particularly among African American children. These abnormalities may work synergistically to create a childhood metabolic syndrome phenotype and may originate earlier in youth than previously proposed.

The purpose of the study was to explore potential correlates of insulin sensitivity, fasting insulin, and insulin resistance, and to determine the best model to predict them in young children. The study of more than 100 healthy children, ages 7-9, found that fat in the liver, abdominal fat, and fat oxidation predicted insulin resistance and appear to be early markers for the metabolic syndrome via a mechanism of impaired lipid metabolism and fat oxidation. Impaired metabolic function may be due, in part, to pre-and post natal factors that are modified by current physical activity. Therefore, race, low or high pregnancy weight and/or birth weight, and low physical activity collectively create a phenotype for poor metabolic function leading to increased risk for insulin resistance in young children.

"Although some of the risk factors cannot be changed, pregnancy weight, birth weight, and physical activity can all be modified and are targets for early intervention to prevent or delay insulin resistance and reduce the risk for metabolic syndrome," noted Dr. Sothern, who is the study's principal investigator.

Comparison of low- and high-carbohydrate diets for type 2 diabetes management: a randomized trial. - PubMed - NCBI
Both diets achieved substantial weight loss and reduced HbA1c and fasting glucose. The LC diet, which was high in unsaturated fat and low in saturated fat, achieved greater improvements in the lipid profile, blood glucose stability, and reductions in diabetes medication requirements, suggesting an effective strategy for the optimization of T2D management. This trial was registered at as ACTRN12612000369820.

CD317 Activates EGFR by Regulating Its Association with Lipid Rafts | Cancer Research
EGFR regulates various fundamental cellular processes, and its constitutive activation is a common driver for cancer. Anti-EGFR therapies have shown benefit in cancer patients, yet drug resistance almost inevitably develops, emphasizing the need for a better understanding of the mechanisms that govern EGFR activation. Here we report that CD317, a surface molecule with a unique topology, activated EGFR in hepatocellular carcinoma (HCC) cells by regulating its localization on the plasma membrane. CD317 was upregulated in HCC cells, promoting cell-cycle progression and enhancing tumorigenic potential in a manner dependent on EGFR. Mechanistically, CD317 associated with lipid rafts and released EGFR from these ordered membrane domains, facilitating the activation of EGFR and the initiation of downstream signaling pathways, including the Ras–Raf–MEK–ERK and JAK–STAT pathways. Moreover, in HCC mouse models and patient samples, upregulation of CD317 correlated with EGFR activation. These results reveal a previously unrecognized mode of regulation for EGFR and suggest CD317 as an alternative target for treating EGFR-driven malignancies.

Effects of detergents on the redistribution of gangliosides and GPI-anchored proteins in brain tissue sections. - PubMed - NCBI
> Gangliosides and glycosylphosphatidylinositol (GPI)-anchored proteins contain lipid tails that tether them to the outer side of the cell membrane. This mode of association with the cell membrane enables them to take part in the organization of lipid rafts, but it also permits gangliosides and GPI-anchored proteins to be actively released from one cell and inserted into the membrane of another cell. Recently, we reported that under conditions of lipid raft isolation, Triton X-100 causes significant redistribution of both gangliosides and GPI-anchored proteins. Aiming to find a less disruptive detergent, we evaluated the effects of CHAPS, Saponin, deoxycholic acid, Trappsol, Tween 20, Triton X-100, Brij 96V, Brij 98, and SDS on brain tissue sections. At room temperature, all detergents (1% concentration) extracted significant amounts of both gangliosides and Thy-1. At 4C, the extraction was weaker, but Triton X-100, CHAPS, and deoxycholic acid caused significant redistribution of GD1a and Thy-1 from gray matter into the white matter. Both redistribution and extraction were significantly augmented when sections were incubated with detergents in the presence of primary antibodies. Of the nine tested detergents, none is the ideal choice. However, Brij 96V appears to be able to suffici

perilla oil Effects of perilla oil on plasma concentrations of cardioprotective (n-3) fatty acids and lipid profiles in mice
Dr Gundry
Perilla oil, which contains a very high level of ALA (40-64%) similar to flaxseed oil, has been reported to shows anti-atherosclerosis properties in Japanish quail [13,14]. Dietary flaxseed meal exerts protective effects against hypertriglyceridemia and steatosis of the liver in an animal model of obesity [15].

The purpose of this study was to evaluate the effects of dietary perilla oil as well as several vegetable oils on plasma lipid profiles and cardioprotective (n-3) PUFA levels in mice.
