Ere sacrificed to gather the blood,liver,white adipose tissue (WAT),and brown adipose tissue (BAT). Because an definitely decreased dietary intake was observed for two rats belonging for the M or Hgroups (M_ and H_ in identical number),the use of these two rats were not included in all analyses to achieve consistency inside the isoenergetic study (n in every group). Serum and plasma have been extracted making use of common solutions and separated from complete blood. Smaller hepatic pieces had been immersed into RNAlater (Qiagen,Tokyo,Japan). The rest hepatic pieces,WAT,and BAT have been frozen straight away following extirpation applying liquid nitrogen. All samples were stored at or until analysis.Measurement of blood biochemical parametersAll blood biochemical parameters,except insulin,listed in Table ,had been analyzed by Nagahama Life Science (Shiga,Japan). Plasma was applied to measure glucose,pyruvic acid,total lipids,phospholipids,and total ketone bodies. Other parameters have been assayed utilizing the serum. Serum insulin levels were measured by using the rat insulin ELISA kit (Morinaga Institute of Biological Science,Kanagawa,Japan).Measurement of hepatic lipidsMethodsAnimalsThreeweekold male Wistar rats (Charles River Laboratories Japan,Kanagawa,Japan) have been housed inside a temperature and humiditycontrolled room having a h lightdark cycle (light ::,dark ::).Hepatic lipids were extracted according to a earlier system . Briefly,mg of frozen hepatic pieces had been homogenized in mL of cooled chloroformmethanol solution applying a multibead shocker (Yasui Kikai Corporation,Osaka,Japan). Filtered samples have been adjusted to mL with chloroformmethanol option and were washed with . mL of purified water. Subsequent washes have been performed by adding . mL of chloroformmethanolwater resolution (::.),along with the resulting extracts had been dried by evaporation. Extracted lipids have been resolved with mL of isopropanol.Tanaka et al.

Antisense RNA was synthesized from or ng of purified total RNA,and biotinylated complementary RNA (cRNA) was obtained applying a GeneChip ‘IVT Express Kit (Affymetrix,Santa Clara,CA,USA). The cRNA was fragmented and hybridized to a GeneChip PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/24085265 Rat Genome . Array (Affymetrix) for h at . The arrays were washed and stained with phycoerythri.
