| 1 | 低温逆境中不同抗寒性植物细胞内Ca^(2+)稳定平衡的区别(英文)显示文摘电镜细胞化学观察揭示 ,不抗寒的玉米 (ZeamaysL .cv.BlackMexicanSweet)和抗寒的小偃麦 (Triticumsect.Trititrigiamackey)细胞在 2 6℃悬浮培养时 ,标志Ca2 + 定位的锑酸钙沉淀物主要分布在液泡内 ,细胞质和细胞核中很少见到Ca2 + 沉淀 ;标志Ca2 + _ATPase活性反应的磷酸铈沉淀物丰富地分布在质膜上 ,显示这两种植物质膜Ca2 + _ATPase在 2 6℃培养中有着较高的活性。当这二者的细胞在 4℃低温培养 1h和 3h后 ,二者细胞质和细胞核中的Ca2 + 浓度都明显地增加 ,但质膜Ca2 + _ATPase活性没有明显改变。在继续延长低温培养后 ,二者之间的Ca2 +水平和Ca2 + _ATPase活性发生明显的区别 :在不抗寒的玉米细胞中 ,质膜Ca2 + _ATPase活性显著降低 ,甚至完全失活 ,细胞内增加的Ca2 + 水平不降低 ,不能恢复Ca2 + 的稳定平衡 ,细胞的精细结构受破坏 ;抗寒的小偃麦细胞则相反 ,在 3h以后的低温培养过程中 (至 3d) ,质膜Ca2 + _ATPase仍然保持高活性 ,细胞内增加的Ca2 + 浓度迅速降低 ,恢复Ca2 + 的稳定平衡 ,并提高抗寒力。这些结果表明 ,植物在低温条件下 ,质膜Ca2 + _ATPase活性的维持亦即细胞内Ca2 + 稳定平衡的恢复与其抗寒性有着密切的关系 ,对于它们在逆境中生存起着重要作用。 | 简令成 孙龙华 李积宏 王红 孙德兰 Paul HLI | 2000 | Acta Botanica Sinica2000,42,4: | 13 |
| 2 | Caffeic acid phenethyl ester protects against oxidative stress and dampens inflammation via heme oxygenase 1显示文摘Periodontal disease is associated with chronic oxidative stress and inflammation. Caffeic acid phenethyl ester(CAPE), which is a potent inducer of heme oxygenase 1(HO1), is a central active component of propolis, and the application of propolis improves periodontal status in diabetic patients. Here, primary murine macrophages were exposed to CAPE. Target gene expression was assessed by whole-genome microarray, RT-PCR and Western blotting. The antioxidative and anti-inflammatory activities of CAPE were examined by exposure of the cells to hydrogen peroxide, saliva and periodontal pathogens. The involvement of HO1 was investigated with the HO1 inhibitor tin protoporphyrin(SnPP) and knockout mice for Nrf2, which is a transcription factor for detoxifying enzymes. CAPE increased HO1 and other heat shock proteins in murine macrophages. A p38 MAPK inhibitor and Nrf2 knockout attenuated CAPE-induced HO1 expression in macrophages. CAPE exerted strong antioxidative activity. Additionally, CAPE reduced the inflammatory response to saliva and periodontal pathogens. Blocking HO1 decreased the antioxidative activity and attenuated the anti-inflammatory activity of CAPE. In conclusion, CAPE exerted its antioxidative effects through the Nrf2-mediated HO1 pathway and its anti-inflammatory effects through NF-κB inhibition. However, preclinical models evaluating the use of CAPE in periodontal inflammation are necessary in future studies. | Alexandra St?hli Ceeneena Ubaidha Maheen Franz Josef Strauss Sigrun Eick Anton Sculean Reinhard Gruber | 2019 | International Journal of Oral Science2019,11,1: | 4 |
