Nuclear TAR DNA-binding protein 43 A new target for amyotrophic lateral sclerosis treatment

引用

Neural Regeneration Research 2013年第35期8卷 3284-3295页

作者： Mei Zheng Yujie Shi dongsheng fan Department of Neurology Peking University Third Hospital School of Pharmaceutical Sciences Peking University

Abnormal TAR DNA-binding protein 43 （TDP-43） inclusion bodies can be detected in the degen- erative neurons of amyotrophic lateral sclerosis. In this study, we induced chronic oxidative stress injury by applying malonate to cultured mouse cortical motor neurons. In the later stages of the malonate insult, TDP-43 expression reduced in the nuclei and transferred to the cytoplasm. This was accompanied by neuronal death, mimicking the pathological changes in TDP-43 that are seen in patients with amyotrophic lateral sclerosis. Interestingly, in the early stages of the response to malonate treatment, nuclear TDP-43 expression increased, and neurons remained relatively intact, without inclusion bodies or fragmentation. Therefore, we hypothesized that the increase of nuclear TDP-43 expression might be a pro-survival factor against oxidative stress injury. This hypothesis was confirmed by an in vitro transgenic experiment, in which overexpression of wild type mouse TDP-43 in cultured cortical motor neurons significantly reduced malonate-induced neuronal death. Our findings suggest that the loss of function of TDP-43 is an important cause of neuronal degen- eration, and upregulation of nuclear TDP-43 expression might be neuroprotective in amyotrophic lateral sclerosis.

Neural Regeneration Research 2012年第30期7卷 2384-2391页

作者： Hongli Wang dongsheng fan Tianpei Hong Department of Neurology Peking University Third Hospital Beijing 1 O0191 China

The present study enrolled 251 diabetic patients, including 101 with neuropathy and 150 without neuropathy. Of the 150 patients, 100 had no complications, such as retinopathy, nephropathy, or neuropathy. Polymerase chain reaction-restriction fragment length polymorphism analysis was used to identify methylenetetrahydrofolate reductase gene variants. Plasma homocysteine levels were also measured. Homocysteine levels and the frequency of hyperhomocysteinemia were significantly higher in patients with diabetic peripheral neuropathy compared with diabetic patients without neuropathy （P 〈 0.05）. In logistic regression analysis with neuropathy as the dependent variable, the frequency of C677T in methylenetetrahydrofolate reductase was significantly higher in patients with diabetic peripheral neuropathy compared with patients without diabetic complications. Homocysteine levels were significantly higher in patients with diabetic peripheral neuropathy carrying the 677T allele and low folic acid levels. In conclusion, hyperhomocysteinemia is an independent risk factor for diabetic neuropathy in Chinese patients with diabetes. The C677T polymorphism in methylenetetrahydrofolate reductase and low folic acid levels may be risk factors for diabetic peripheral neuropathy in Chinese patients with diabetes.

Neural Regeneration Research 2013年第36期8卷 3434-3440页

作者： Hongli Wang dongsheng fan Yingshuang Zhang Department of Neurology Peking University Third Hospital

Angiogenin is associated with the pathogenesis of diabetic peripheral neuropathy. Here, we se- quenced the coding region of the angiogenin gene in genomic DNA from 207 patients with type 2 diabetes mellitus （129 diabetic peripheral neuropathy patients and 78 diabetic non-neuropathy pa- tients） and 268 healthy controls. All subjects were from the Han population of northern China. No mutations were found. We then compared the genotype and allele frequencies of the angiogenin synonymous single nucleotide polymorphism rs11701 between the diabetic peripheral neuropathy patients and controls, and between the diabetic neuropathy and non-neuropathy patients, using a case-control design. We detected no statistically significant genetic associations. Angiogenin may not be associated with genetic susceptibility to diabetic peripheral neuropathy in the Han population of northern China.

Adenosine monophosphate-activated protein kinase activation enhances embryonic neural stem cell apoptosis in a mouse model of amyotrophic lateral sclerosis

引用

Neural Regeneration Research 2014年第19期9卷 1770-1778页

作者： Yanling Sui Zichun Zhao Rong Liu Bin Cai dongsheng fan Department of Neurology Peking University Third Hospital

Alterations in embryonic neural stem cells play crucial roles in the pathogenesis of amyotrophic lateral sclerosis. We hypothesized that embryonic neural stem cells from SOD1G93A individuals might be more susceptible to oxidative injury, resulting in a propensity for neurodegeneration at later stages. In this study, embryonic neural stem cells obtained from human superoxide dis- mutase 1 mutant （SOD1G93A） and wild-type （SOD1wv） mouse models were exposed to H202. We assayed cell viability with mitochondrial succinic dehydrogenase colorimetric reagent, and measured cell apoptosis by flow cytometry. Moreover, we evaluated the expression of the adenos- ine monophosphate-activated protein kinase （AMPK） ct-subunit, paired box 3 （Pax3） protein, and p53 in western blot analyses. Compared with SOD1wr cells, SOD1~93A embryonic neural stem cells were more likely to undergo H202-induced apoptosis. Phosphorylation of AMPKct in SOD1G93A cells was higher than that in SOD1wr cells. Pax3 expression was inversely correlated with the phosphorylation levels of AMPKct. p53 protein levels were also correlated with AMPKct phosphorylation levels. Compound C, an inhibitor of AMPKa, attenuated the effects of H20~. These results suggest that embryonic neural stem cells from SOD1C93A mice are more susceptible to apoptosis in the presence of oxidative stress compared with those from wild-type controls, and the effects are mainly mediated by Pax3 and p53 in the AMPKa pathway.

Estrogen receptor gene polymorphism in a Chinese population with multiple sclerosis

引用

Neural Regeneration Research 2011年第19期6卷 1488-1492页

作者： Qingli Sun Ruping Xie Yu Fu Xiaogang Li dongsheng fan Department of Neurology Peking University Third Hospital Beijing 100191 China

This study sought to elucidate the role of the Pvull and Xbal polymorphisms of the estrogen receptor gene in 74 Chinese patients with multiple sclerosis, and 95 ethnicity-matched controls, using polymerase chain reaction-restriction fragment-length polymorphism analysis. The results revealed that the P allele of Pvull was significantly more prevalent in multiple sclerosis patients compared with controls （P = 0.019）. While distribution frequencies were significantly increased in female multiple sclerosis patients compared with female controls （P = 0.044）, no significant difference was observed between male patients and controls （P〉 0.05）. Frequencies of Ppxx genotypes were significantly higher in multiple sclerosis patients compared with controls （24.3% vs 12.8%, P = 0.025）. Genotypes and alleles of the estrogen receptor were not associated with age, number of attacks or expanded disability status scale scores of patients with multiple sclerosis. These findings indicate that the Pvull but not the Xbal polymorphism in the estrogen receptor gene is associated with susceptibility to multiple sclerosis in the Chinese population. In addition, women with P allele appear to be particularly susceptible to multiple sclerosis.

Brain glioma is a hot topic in recent years; however, brain glioma remains poorly understood. A bibliometric analysis based on the Science Citation Index （SCI） published by the Institute of Scientific Information （ISI） was performed to identify the global research and to improve the understanding of research trends in the brain glioma field from 2001 to 2010. During 2001 to 2010, there were 8 413 papers addressing brain glioma added to the SCI, and this trend is increasing annually. Of these reports, 6 945 papers are written in English. Journals published in the United States had the most papers, including ten core source titles. The Journal of Neuro-Oncology published the most articles followed by Cancer Research. Furthermore, the University of California San Francisco, is the most productive institution for publishing articles in the brain glioma field. Finally, this study highlights the topics in brain glioma research that are being published around th~ world.

Neural Regeneration Research 2011年第22期6卷 1731-1735页

作者： Qingli Sun Yu Fu Aping Sun Yanhong Shou Mei Zheng Xiaogang Li dongsheng fan Department of Neurology Third Hospital of Peking University Beijing 100191 China

OBJECTIVE： To investigate the association of E-selectin $128R polymorphisms with ischemic stroke. DATA SOURCES： A computer-based online search was conducted in PubMed, Elsevier, Ovid Database, the China National Knowledge Infrastructure, and Wanfang Database between January 1998 and December 2010. STUDY SELECTION： Case-controlled studies addressing the association of the E-selectin polymorphism and ischemic stroke were included in this review. The genotype distribution complied with the Hardy-Weinberg genetic equilibrium. The included reports were evaluated by two authors for strict quality screening. Meta-analysis software, REVMAN 5.1, was used to investigate heterogeneity, pooled odds ratio （OR） and 95% confidence interval （CO in individual studies. MAIN OUTCOME MEASURES： Genotype and allele distributions at the E-selectin $128R site. RESULTS： Six case-controlled studies were included after screening and application of inclusion and exclusion criteria. There was no heterogeneity in the genotype and allele frequencies, and no publication bias was found. Meta-analysis of the pooled data showed that the OR value of the （AC＋CC）/AA genotype was 1.93 （95% CI： 1.55 2.41, Z= 5.80, P 〈 0.000 01）, and the ORfor the C/A allele was 1.80 （95% CI： 1.47 2.22, Z= 5.59, P 〈 0.000 01） in the ischemic stroke group, compared with control group. Results of pooled data in Chinese subjects showed that the ORvalue of （AC＋CC）/AA was 2.36 （95% CI： 1.68 3.31, Z = 4.99, P 〈 0.000 01）, and the OR value of the C/A allele was 2.25 （95% CI： 1.63 3.12, Z= 4.89, P 〈 0.000 01）. CONCLUSION： Polymorphism of E-selectin S128R was significantly associated with susceptibility to ischemic stroke; the AC and CC genotypes as well as the C allele may be factors associated with susceptibility to ischemic stroke.
