Activation of UCP2 by anethole trithione suppresses neuroinflammation after intracerebral hemorrhage.

Intracerebral hemorrhage (ICH) is a devastating disease, in which neuroinflammation substantially contributes to brain injury. Uncoupling protein 2 (UCP2) is a member of the mitochondrial anion carrier family, which uncouples oxidative phosphorylation from ATP synthesis by facilitating proton leak across the mitochondrial inner membrane. UCP2 has been reported to modulate inflammation.

[Study on separation of bacteria on the surface of mature manganese sand and the ability of oxidating Fe2+ and Mn2+].

Seven strains of bacteria which were separated from the active membrane on the mature manganese sand which are from different power plants. After identifying they are Leptothrix, Sphaerotilus and Siderocapsa. Studies show that the three strains of bacteria have a better removal of Fe2+, in which Siderocapsa No.

Frequent loss of membranous E-cadherin in gastric cancers: A cross-talk with Wnt in determining the fate of beta-catenin.

The potential correlation of E-cadherin reduction and Wnt2 up-regulation in determining the intracellular distribution of beta-catenin in gastric cancers was investigated by the methods of frozen tissue array-based immunohistochemistry, Western blot and RT-PCR analysis. It was revealed that membranous E-cadherin was reduced frequently in the two major subtypes of gastric cancer (intestinal gastric cancer, i-GC and diffuse gastric cancer, d-GC) and closely correlated with the risk of lymphoid node metastasis (P < 0.05).

Correlation of Wnt-2 expression and beta-catenin intracellular accumulation in Chinese gastric cancers: relevance with tumour dissemination.

Wnt/beta-catenin signalling pathway is integrally associated with human tumour development and progression. Aberrant beta-catenin intracellular distribution has been found in gastric cancer, but the pattern of Wnt expression in stepwise gastrocarcinogenesis and its potential influence in beta-catenin distribution are still lesser known. By the methods of frozen tissue array-based immunohistochemistry, Western blot analysis and RT-PCR, a paralleled study was conducted to check Wnt2 expression and beta-catenin intracellular distribution in two major subtypes of gastric cancers (intestinal gastric cancer, i-GC and diffuse gastric cancer, d-GC) and their premalignant (intestinal metaplasia, IM and chronic gastritis, CG) and noncancerous counterparts.
