ET We utilized ASO as therapeutic modality, CerS6 ASO molecules designed and synthesized were initially screened for in-vitro knock-down (KD) potency and cytotoxicity. Ceramides (Cer) are implicated in obesity-associated skeletal muscle and perhaps adipocyte insulin resistance. Hyperglycemia in the face of hyperinsulinemia is attributed to insulin resistance. endobj (Copyright \251 2019, American Association for the Advancement of Science\ )Tj Next, we utilized leptin deficiency ob/ob and high fat diet (HFD) induced obese mouse models for pharmacological efficacy study. Insulin resistance is a key feature of type 2 diabetes, and the strong association between fat oversupply and defective insulin action in target tissues, especially skeletal muscle and liver, has motivated the search for intracellular lipid mediators that can interfere with insulin signaling and glucose homeostasis. Haploinsufficiency for ceramide synthase 2 (CerS2), the dominant isoform in the liver that preferentially makes very-long-chain (C22/C24/C24:1) ceramides, led to compensatory increases in long-chain C16-ceramides and conferred susceptibility to diet-induced steatohepatitis and insulin resistance. Science Magazine Article In a post hoc ancillary analysis of the Gruppo Italiano per lo Studio della Sopravvivenza nella Insufficienza Cardiaca‐Heart Failure (GISSI‐HF; NCT00336336) trial, we randomly selected a sample of 200 ambulatory patients with chronic HF who died due to cardiovascular causes and 200 patients who were alive at the end of the trial (after a median follow‐up period of 3.9 years). 1), the inhibitor is able to decrease ceramide synthesis without elevating intermediates such as sphinganine, which are upstream of ceramide formation and also have biological effects (9).

Results: Overexpression of either adiponectin receptor isoform in the adipocyte or hepatocyte is sufficient to enhance ceramidase activity, whole body glucose metabolism, and hepatic insulin sensitivity, while opposing hepatic steatosis. We examined whether the sphingolipid content of human subcutaneous adipose tissue and plasma varies by obesity and sex as well as the relationship between ceramide content and metabolic indices. (http://science.sciencemag.org/content/365/6451/319#BIBL)Tj These represent the first inducible genetic models that acutely manipulate adiponectin receptor signaling in adult mouse tissues, which allows us to directly assess AdipoR signaling on glucose and lipid metabolism. uuid:084660b6-1dd2-11b2-0a00-aa0000000000 Collectively, these data have two important implications. Only in NASH were hepatic dihydroceramides (16:0, 22:0, and 24:1) and lactosylceramides increased. WebMD tells you about seven types of foods to help control blood sugar, spare you from boredom, and stave off hunger. -1.668 0 Td lowering ceramides, Resistance to insulin is a pathophysiological state related to the decreased response of peripheral tissues to the insulin action, hyperinsulinemia and raised blood glucose levels caused by increased hepatic glucose outflow.

The title )Tj 0 g When we applied a Bonferroni correction for multiple comparisons (using a P‐threshold 0.05/5 ceramide ratios = 0.01), none of the five plasma ratios of each ceramide with Cer(d18:1/24:0) remained statistically associated with the risk of cardiovascular mortality (with adjusted hazard ratios ranging from 1.10 to 1.23). <> It remains unresolved whether obesity-associated alterations of specific CerSs and their defined acyl-chain length ceramides contribute to the manifestation of metabolic diseases. Our investigations identified specific and selective therapeutic valid ASO for CerS6 ablation in in-vivo. Christine M. Kusminski's 12 research works with 160 citations and 1,575 reads, including: Dermal adipocytes contribute to the metabolic regulation of dermal fibroblasts application/pdf endstream These significant associations were attenuated after adjustment for multiple established risk factors, New York Heart Association functional class, left ventricular ejection fraction, use of medications, plasma pentraxin‐3 levels, and, especially, plasma N‐terminal pro‐brain natriuretic peptide (NT‐proBNP) levels.
