Abstract: In order to investigate the changes of different metabolites of white adipose tissue(WAT) and brown adipose tissue(BAT) in Tupaia belangeri under cold acclimation,WAT and BAT were collected between control and cold acclimation group acclimated for 28 days in the present study,which were analyzed using non-targeted metabolome(liquid chromatography-mass spectrometer,LC-MS) detection technology.The results showed that 7 different metabolites were significantly up-regulated of WAT in cold acclimation group compared with that of control group;there were 25 different metabolites in BAT,among which 23 were up-regulated and 2 were down-regulated significantly,which were mainly involved in pathways of tricarboxylic acid cycle,lipid metabolism,amino acid metabolism and glucose metabolism.All of the above results indicated that T.belangeri could use different metabolites in different tissues to resist lower temperature and improve survival rate.

摘要: 为探究冷驯化条件下中缅树鼩(Tupaia belangeri)白色脂肪组织(WAT)和褐色脂肪组织(BAT)的差异代谢物变化,本研究采集对照组和冷驯化28天组中缅树鼩的WAT和BAT,采用非靶向代谢组液相色谱—质谱联用检测技术分析其差异代谢物含量变化。结果表明,冷驯化组较对照组WAT中有7种差异代谢物显著上调;BAT中有25种差异代谢物,其中23种差异代谢物显著上调,2种差异代谢物显著下调,主要参与三羧酸循环、脂类代谢、氨基酸代谢和糖代谢等。以上结果说明中缅树鼩通过利用脂肪组织的不同差异代谢物来抵御低温环境,提高生存率。
