Ere sacrificed to collect the blood,liver,white adipose tissue (WAT),and brown adipose tissue (BAT). Because an definitely decreased dietary intake was observed for two rats belonging to the M or Hgroups (M_ and H_ in identical number),the use of these two rats were not incorporated in all analyses to attain consistency inside the isoenergetic study (n in every single group). Serum and plasma have been extracted making use of normal procedures and separated from whole blood. Modest hepatic pieces had been immersed into RNAlater (Qiagen,Tokyo,Japan). The rest hepatic pieces,WAT,and BAT have been frozen straight away just after extirpation working with liquid nitrogen. All samples were stored at or till analysis.Measurement of blood biochemical parametersAll blood biochemical parameters,except insulin,listed in Table ,were 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 have been measured by utilizing 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) were housed in a temperature and humiditycontrolled area using a h lightdark cycle (light ::,dark ::).Hepatic lipids had been extracted in accordance with a preceding method . Briefly,mg of frozen hepatic pieces had been homogenized in mL of cooled chloroformmethanol option utilizing a multibead shocker (Yasui Kikai Corporation,Osaka,Japan). Filtered samples have been adjusted to mL with chloroformmethanol answer and have been washed with . mL of purified water. Subsequent washes were performed by adding . mL of chloroformmethanolwater resolution (::.),plus the resulting extracts have been dried by evaporation. Extracted lipids were 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 utilizing 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 had been washed and stained with phycoerythri.
