2The herbal compound geniposide rescues formaldehyde-induced apoptosis in N2a neuroblastoma cells显示文摘The herbal medicine Tong Luo Jiu Nao(TLJN)contains geniposide(GP)and ginsenoside Rg1 at a molar ratio of 10:1.Rg1 is the major component of another herbal medicine,panax notoginseng saponin(PNS).TLJN has been shown to strengthen brain function in humans,and in animals it improves learning and memory.We have previously shown that TLJN reduces amyloidogenic processing in Alzheimer’s disease(AD)mouse models.Together this suggests TLJN may be a potential treatment for patients with dementia.Because chronic damage of the central nervous system by formaldehyde(FA)has been presented as a risk factor for age-associated cognitive dysfunction,in the present study we investigated the protective effect of both TLJN and GP in neuron-like cells exposed to FA.FA-exposed murine N2a neuroblastoma cells were incubated with TLJN,its main ingredient GP,as well as PNS,to measure cell viability and morphology,the rate of apoptosis and expression of genes encoding Akt,FOXO3,Bcl2 and p53.The CCK-8 assay,cytoskeletal staining and flow cytometry were used to test cell viability,morphology and apoptosis,respectively.Fluorescent quantitative real-time PCR(qRT-PCR)was used to monitor changes in gene expression,and HPLC to determine the rate of FA clearance.Treatment of N2a cells with 0.09 mmol L?1 FA for 24 h significantly reduced cell viability,changed cell morphology and promoted apoptosis.Both TLJN and GP conferred neuroprotection to FA-treated N2a cells,whereas PNS,which had to be used at lower concentrations because of its toxicity,did not.Our data demonstrate that TLJN can rescue neuronal damage caused by FA and that its main ingredient,GP,has a major role in this efficacy.This presents purified GP as a drug or lead compound for the treatment of AD.CHEN JinYan SUN MengRu WANG XingHua LU Jing WEI Yan TAN Yan LIU Ying GTZ Jürgen HE RongQiao HUA Qian 2014Science China(Life Sciences)2014,57,4:15
3Mechanism of variations in environmental magnetic proxies of lake sediments from Nam Co, Tibet during the Holocene显示文摘High-resolution environmental records from the Tibetan Plateau are essential to understand past global climatic and environmental changes. Magnetic minerals in lake sediments are important proxies to reconstruct environmental and climatic changes. Nam Co (lake) is a typical great lake in the transitional region of southwest monsoon in the Tibetan Plateau. Previous studies have extensively focused on geochemistry, microfossils, sedimentology and biochemistry analysis of Nam Co, which provides sound interpretation of paleoclimatic and paleoenvironmental changes. However, up to now, no systematic environmental magnetic studies have been carried out. Therefore, high-resolution and systematic magnetic studies combined with geochemical parameters were carried on lake sediments of core NC 08/01 from Nam Co for the Holocene period (11.3 cal ka BP) in order to explore how magnetic properties of the sediments respond to climatic changes. Based on variations of magnetic proxies, the sequence can be separated into 3 units. Unit 1 (236-199 cm, 11.3-7.8 cal ka BP) contains dominantly coarse-grained magnetite with homogeneous grain size. A positive correlation between magnetite and Ti strongly suggests that these coarse-grained detrital magnetites reflect detrital input signals due to insignificant effects of postdepositional dissolution processes on these coarse-grained magnetite particles. For Unit 2 (198-102 cm, 7.8-2.1 cal ka BP), magnetic grain size is finer and the corresponding concentration of magnetite is also reduced. This is mainly due to significant dissolution of these fine-grained detrital magnetite particles, which were transported under reduced water flow conditions during this period. For Unit 3 (101-0 cm, 2.1-0 cal ka BP), the bulk magnetic properties are dominated by a mixture of single domain biogenic magnetite and detrital magnetite. The concentration of magnetic minerals is not correlated with the Ti content. In conclusion, the preservation of magnetic minerals in the lake sediment and thus the corresponding magnetic properties are related to the initial grain size. Combination of magnetic properties (including variation of grain size and concentration) and other proxies of detrital inputs (e.g. Ti) can be used to infer the variation of redox conditions in Nam Co. These results provide a viable framework for reconstructing the paleoenvironmental changes of this lake.SU YouLiang GAO Xing LIU QingSong HU PengXiang DUAN ZongQi JIANG ZhaoXia WANG JunBo ZHU LiPing DOBERSCHüTZ Stefan MUSBACHER Roland DAUT Gerhard HABERZETTL Torsten 2013Chinese Science Bulletin2013,58,13:2
