Hypothermia is utilized with increasing frequency to protect organs such as the brain against ischemic injury. Though a principal mechanism of hypothermic protection would be suppression of metabolism, its pleiotropic effects are as yet incompletely understood. To analyze hypothermia-induced proteomic changes, we employed fluorescence-based two-dimensional(2-D) difference gel electrophoresis(DIGE) and matrix-assisted laser desorption/ionization-time-of-flight(MALDI-TOF/TOF) tandem mass spectrometry. Deep hypothermia produced significant down-regulation of the proteins that regulates ATP synthesis or muscle contraction in rat heart muscle. Hypothermia also produced significant down-regulation of the following cellular components and biological processes or pathways in rat livers : endoplasmic reticulum(ER), mitochondria, ATP binding, amino acid metabolism, urea cycle, response to oxidative stress, anti-apoptosis, negative regulation of apoptosis. These changes were similar to those in hibernating animals except for both ER and apoptosis-related pathways, which are conversely up-regulated in hibernating mammals. This discrepancy needs to be investigated further in future research.

低温越来越频繁地用于保护大脑等器官免受缺血性损伤。尽管低温保护的主要机制是抑制新陈代谢，但其多效作用尚未完全了解。为了分析低温引起的蛋白质组变化，我们采用基于荧光的二维（2-D）差异凝胶电泳（DIGE）和基质辅助激光解吸/电离飞行时间（MALDI-TOF/TOF）串联质量光谱测定法。深低温导致大鼠心肌中调节 ATP 合成或肌肉收缩的蛋白质显着下调。低温还导致大鼠肝脏中以下细胞成分和生物过程或途径显着下调：内质网（ER）、线粒体、ATP 结合、氨基酸代谢、尿素循环、氧化应激反应、抗凋亡、负调节细胞凋亡。这些变化与冬眠动物中的变化相似，但 ER 和细胞凋亡相关途径除外，这些途径在冬眠哺乳动物中相反上调。这种差异需要在未来的研究中进一步调查。
