It can cause necrosis of brain tissue and cognitive dysfunction. Our previous work had proved that a natural antioxidant shikonin possessed protective effect on cerebral ischemic injury. Here we investigated the effects of shikonin on carbon ion beam induced radiation brain injury in mice. Pretreatment with shikonin significantly increased the SOD and CAT activities and the ratio of GSH/GSSG in mouse brain tissues compared with irradiated group （P〈0.01）, while obviously reduced the MDA and PCO contents and the RO$ levels derived from of the brain mitochondria.展开更多

Among the identified proteins, ubiquitin carboxy-terminal hydrolase L1 （UCH-L1） is associated with the cell cycle[1] and that it influences proliferation in ovarian tissues. We analyzed the expression of UCH-L1 and the proliferation marker proliferation cell nuclear antigen （PCNA） following CIR using immunoblotting and immunofluorescence. The proteomics and biochemical results provide insight into the underlying mechanisms of CIR toxicity in ovarian tissues.展开更多
酸敏感离子通道3(acid-sensing ion channels 3,ASIC3)是对p H值改变最敏感的酸受体。在对ASIC3及其基因敲除小鼠(ASIC3-/-小鼠)的研究中发现,ASIC3参与痛觉、酸味觉、感受伤害性刺激、心肌缺血等多种生理和病理过程,并发挥重要作用。...酸敏感离子通道3(acid-sensing ion channels 3,ASIC3)是对p H值改变最敏感的酸受体。在对ASIC3及其基因敲除小鼠(ASIC3-/-小鼠)的研究中发现,ASIC3参与痛觉、酸味觉、感受伤害性刺激、心肌缺血等多种生理和病理过程,并发挥重要作用。这些成果为在分子水平研究针刺治疗疾病的机制提供条件和基础。展开更多
