Ere sacrificed to collect the blood,liver,white adipose tissue (WAT),and brown adipose tissue (BAT). Since an naturally decreased dietary intake was observed for two rats belonging towards 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 single group). Serum and plasma were extracted employing typical solutions and separated from whole blood. Little hepatic pieces were immersed into RNAlater (Qiagen,Tokyo,Japan). The rest hepatic pieces,WAT,and BAT were frozen quickly just after extirpation working with liquid nitrogen. All samples had been 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 used to measure glucose,pyruvic acid,total lipids,phospholipids,and total ketone bodies. Other parameters were assayed making use of the serum. Serum BI-9564 insulin levels had been 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) were housed within a temperature and humiditycontrolled area with a h lightdark cycle (light ::,dark ::).Hepatic lipids had been extracted in line with a prior strategy . Briefly,mg of frozen hepatic pieces were homogenized in mL of cooled chloroformmethanol resolution using a multibead shocker (Yasui Kikai Corporation,Osaka,Japan). Filtered samples had been adjusted to mL with chloroformmethanol solution and were washed with . mL of purified water. Subsequent washes were performed by adding . mL of chloroformmethanolwater remedy (::.),and the resulting extracts had 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 using 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.
