Artemisia sacrorum Ledeb. (Compositae) (ASL) is a traditional Chinese medicine used to treat different hepatic diseases. However, a hypolipidemic effect of ASL on fatty liver disease has not been reported. Therefore, we investigated whether 95% ethanol eluate (EE), an active part of ASL, would attenuate hepatic lipid accumulation in human HepG2 cells by activating AMP-activated protein kinase (...

S9 Mitochondria as a Therapeutic Target 9L.1 Stearoyl-CoA desaturase and insulin signaling — What is the molecular switch? Agnieszka Dobrzyn Laboratory of Cell Signaling and Metabolic Disorders, Nencki Institute of Experimental Biology, Warsaw, Poland E-mail: [email protected] Insulin resistance, an impaired biological response to circulating insulin, is a disorder common to most of the ob...

Artemisia sacrorum Ledeb. (Compositae) (ASL) has long been used in Oriental folk medicine to treat diverse hepatic diseases. In this study, we investigated the effect of ASL on adipocyte differentiation in 3T3-L1 cells. ASL significantly suppressed 3T3-L1 differentiation in a concentration-dependent manner. A significant increase of AMP-activated protein kinase (AMPK) was observed when the cell...

Dietary intake of whole grains reduces the incidence of chronic diseases such as obesity, diabetes, cardiovascular disease, and cancer. In an earlier study, we showed that Panicum miliaceum L. extract (PME) exhibited the highest anti-lipogenic activity in 3T3-L1 cells among extracts of nine different cereal grains tested. In this study, we hypothesized that PME in the diet would lead to weight ...

The spondylocostal dysostoses (SCDs) are a heterogeneous group of vertebral malsegmentation disorders that arise during embryonic development by a disruption of somitogenesis. Previously, we had identified two genes that cause a subset of autosomal recessive forms of this disease: DLL3 (SCD1) and MESP2 (SCD2). These genes are important components of the Notch signaling pathway, which has multip...

Lipids synthesized on the skin are crucial to antimicrobial barrier. Skin lipids also facilitate survival of lipophilic commensals in an otherwise dry and acidic ecological landscape. Skin-specific stearoyl-Coenzyme A desaturase 1 (SCD1) knockout mice known have dry, inflamed skin, with sebocyte atrophy decreased synthesis monounsaturated fatty acids, triglycerides, wax diesters. Characterizing...

Abstract BACKGROUND Mutant isocitrate dehydrogenase (IDH) produces 2-hydroxyglutarate (D2HG) and causes metabolic reprograming, but so far, little is known about the role of mutant IDH D2HG in de novo lipogenesis fatty acids synthesis. In this study, to develop a feasible drug for glioma, we targeted Stearoyl-CoA desaturase 1 (SCD1) catalyzing biosynthesis monosaturated (MUFA) suppress glioma p...

A single gene encoding a 6-desaturase (FADS2) has been isolated and characterized in mammalian species. This 6-desaturase plays a major role in the biosynthesis of PUFAs (polyunsaturated fatty acids). It catalyses the rate-limiting desaturation of linoleic acid (C18:2 n− 6) and α-linolenic acid (C18:3 n− 3) required for the biosynthesis of long-chain PUFAs. Moreover, recent studies have provide...

The transcriptional repressor B-cell Lymphoma 6 (Bcl6) was recently identified in a profile of genes regulated in adipocytes, suggesting a relationship between Bcl6 and metabolic regulation. As a representative target gene repressed by Bcl6, Suppressor of Cytokine Signaling (Socs) 2 expression was elevated in Bcl6 deficient (KO) mice, including metabolic tissues liver, adipose tissue and muscle...
