Flow-induced Expression and Phosphorylation of VASPin Endothelial Cells

1 Introduction It is well known that mechanical forces have important influence on endothelial cells, in particular, on cytoskeleton reorganization. VASP (vasodilator stimulated phosphoprotein) is a 46 KD actin associated protein. It is a member of Ena/VASP protein family and composed of EVH1, proline-rich and EVH2 domains. It is considered as an important component of the sub-cellular regions where remodelling of the actin cytoskeleton takes place, such as the front of spreading lamell…

Chronic neuroprotective effects of low concentration lithium on SH-SY5Y cells:possible involvement of stress proteins and gene expression

To investigate the molecular mechanism underlying the neuroprotective effect of lithium on cells, in this study, we exposed SH-SY5Y cells to 0.5 mmol/L lithium carbonate(Li2CO2) for 25–50 weeks and then detected the expression levels of some neurobiology related genes and post-translational modifications of stress proteins in SH-SY5Y cells. cDNA arrays showed that pyruvate kinase 2(PKM2) and calmodulin 3(CaM 3) expression levels were significantly down-regulated, phosphatase protein PP2A expression was lightly down-regulated, and casein kinase II(CK2), threonine/tyrosine phosphatase 7(PYST2), and dopamine beta-hydroxylase(DBH) expression levels were significantly up-regulated. Besides, western blot analysis of stress proteins(HSP27, HSP70, GRP78 and GRP94) showed an over-expression of two proteins: a 105 kDa protein which is a hyper-phosphorylated isoform of GRP94, and a 108 kDa protein which is a phosphorylated tetramer of HSP27. These results suggest that the neuroprotective effects of lithium are likely related to gene expressions and post-translational modifications of proteins cited above.

Interleukin 28B-related polymorphisms: A pathway for understanding hepatitis C virus infection?

AIM:To analyze the role of rs12979860 and rs8099917polymorphisms in hepatitis C virus(HCV)genotype 1infection of Brazilians.METHODS:A total of 145 adult patients diagnosed with genotype 1 chronic hepatitis C(CHC)who had completed a 48-wk regimen of pegylated-interferonα-2a or-2b plus ribavirin combination therapy were recruited from six large urban healthcare centers and199 healthy blood donors(controls)from a single site between January 2010 and January 2012.Data on the patients’response to treatment was collected.Polymerase chain reaction-restriction fragment length polymorphism genotyping of the interleukin(IL)28B gene fragment encompassing the single nucleotide polymorphisms(SNPs)rs12979860(C/T)and rs8099917(T/G)was carried out for 79 of the CHC patients and 199 of the controls.Bi-directional amplicon sequencing of the two SNPs was carried out for the remaining 66 CHC patients.RESULTS:SNP rs12979860 genotyping was successful in 99.5%of the controls and 97.2%of the CHC patients,whereas the SNP rs8099917 genotyping was successful in 95.5%of the controls and 100%of the CHC patients.The genotype and allele distributions for both rs12979860 and rs8099917 were significantly different between the control and CHC patient groups,with significantly higher genotype frequencies of CC and TT in the controls(P=0.037 and 0.046,respectively)and of TT and GG in the CHC patients(P=0.0009and 0.0001,respectively).Analysis of the CHC patients who achieved sustained virological response(SVR)to treatment(n=55)indicated that the rs12979860 C allele and CC genotype were predictors of SVR(P=0.02).No significant correlation was found between rs8099917 genotypes and treatment response,but carriers of the T allele showed significantly higher rates of SVR(P=0.02).Linkage disequilibrium analysis of the group that achieved SVR showed a significant association between rs12979860 and rs8099917(P=0.07).CONCLUSION:The higher allele frequency of rs12979860 C and rs8099917 T observed in non-HCVinfected individuals may indicate a potential pro     

氮氧化物致急性肺损伤的临床特点及研究进展

气体中毒是构成中国急性职业中毒的关键部分,化工厂、煤矿、危化品泄露等狭窄空间中氮氧化物中毒可迅速导致中毒患者并发严重的化学性肺损伤,出现低氧血症、胸闷、呼吸障碍等,严重者可发展为急性呼吸窘迫综合征,甚至导致患者死亡。急性肺损伤一直是呼吸和危重病医学界研究的热点和难点,但关于氮氧化物中毒导致急性肺损伤的研究较少,且没有特效治疗手段,救治困难。现就氮氧化物致急性肺损伤的中毒表现、机制、治疗进展展开综述,以期为临床治疗和后续研究工作的开展提供参考。     

正确和完整解读《甲乙经》的学术思想——《甲乙经》析疑五则

《甲乙经》一书,乃《针灸甲乙经》之简称,为晋代皇甫谧据《素问》、《针经》、《针灸治要》三书内容除去重复重新归类编撰而成,是针灸学的一部宝贵典籍。由于年代久远,文字错简脱落者有之,亥豕鲁鱼者有之,字形义训变迁者亦有之,今人一般很难通读之,必须采用研究古籍方法始克奏效。

周围神经卡压综合征影像诊断的研究进展

周围神经经过某些解剖上狭窄部位的急、慢性挤压或者反复摩擦造成局部水肿等炎症反应,使局部容积减小,血液循环障碍,造成该处甚至远处神经发生脱髓鞘改变,出现支配区不同程度的运动及感觉功能障碍的现象称之为神经卡压综合征。传统的周围神经卡压综合征的诊断主要依靠其临床表现、物理检查及电生理检测,是一种主观的判断。近年
