Ere sacrificed to gather the blood,liver,white adipose tissue (WAT),and brown adipose tissue (BAT). For the reason that an of course decreased dietary intake was observed for two rats belonging to the M or Hgroups (M_ and H_ in identical number),the usage of these two rats have been not integrated in all analyses to attain consistency within the isoenergetic study (n in every single group). Serum and plasma have been extracted using typical techniques and separated from entire blood. Tiny hepatic pieces were immersed into RNAlater (Qiagen,Tokyo,Japan). The rest hepatic pieces,WAT,and BAT have been frozen straight away following extirpation working with liquid nitrogen. All samples have been stored at or until analysis.Measurement of blood biochemical parametersAll blood biochemical parameters,except insulin,listed in Table ,have 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 had been assayed employing 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) had been housed within a temperature and humiditycontrolled space using a h lightdark cycle (light ::,dark ::).Hepatic lipids had been extracted in line with a prior system . Briefly,mg of frozen hepatic pieces have 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 were washed with . mL of purified water. Subsequent washes were performed by adding . mL of chloroformmethanolwater answer (::.),and also 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 employing 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 .
