The enolase [EC 4.2.1.11] is an essential enzyme in the glycolytic pathway catalyzing the conversion of 2-phosphoglycerate (2-PGE) to phosphoenolpyruvate (PEP). In this study, a full-length cDNA encoding α-enolase was cloned from rice brown planthopper (Nilaparvata lugens) and is provisionally designated as NlEno1. The cDNA sequence of NlEno1 was 1,851 bp with an open reading frame (ORF) of 1,305 bp and encoding 434 amino acids. The deduced protein shares high identity of 80–87% with ENO1-like protein from Hemiptera, Diptera, and Lepidoptera speices. The NlEno1 showed the highest mRNA expression level in hemolymph, followed by fat body, salivary gland, ovaries and egg, and showed trace mRNA levels in testis. The mRNA of NlEno1 showed up-regulated level in virulent N. lugens population Mudgo, IR56 and IR42 when compared with TN1 population. Injection of double-stranded RNA (dsRNA) of NlEno1 into the adults significantly down-regulated the NlEno1 mRNA level along with decreased eggs and offspring. Moreover, injection of NlEno1-dsRNA decreased mRNA level of Vitellogenin (Vg) gene. These results showed that the NlEno1, as a key glycolytic enzyme, may play roles in regulation of fecundity and adaptation of N. lugens to resistant rice varieties. 相似文献

氦氖激光治疗脑梗死患者对血液流变学、血清神经元特异性稀醇化酶的影响 总被引：1，自引：0，他引：1
目的：观察氦氖激光血管内照射(ILIB)治疗脑梗死患者对血液流交学、血清神经元特异性稀醇化酶(NSK)的影响。方法：38例脑梗死随机分为两组：ILIB组21例，对照组17例，两组均在基础治疗下，ILIB组加用ILIB治疗，对照组不用ILIB。治疗后第3天和第14天检测血液流变学、血清NSE浓度，并行神经功能缺损的评定。结果：两组同步治疗后血液流变学指标除红细胞体积分数外，其余4项指标均有下降，但两组治疗后比较，ILIB组较对照组下降更显著，差异有显著性；血清NSK浓度与神经功能缺损评定，治疗后两组均有下降，但ILIB组下降也更显著，差异有显著性。结论：ILIB可改善脑梗死患者血液流变学情况，且可降低血清NSK浓度，有利于促进神经功能恢复。 相似文献

表面烯醇化酶(surface enolase,SEN)和3-磷酸甘油醛脱氢酶(surface glyceraldehydes -3 - phosphate dehydro - genase,sGAPDH)都是A群链球菌(group A Streptococcus,GAS)没有踌膜结构的膜表面蛋白,它们可能在GAS感染中起到重要的作用.在本研究中,对SEN和sGAPDH在M6型GAS不同生长阶段(即在对数期和稳定期)的表达情况进行检测分析.取对数期(OD600 =0.5 -0.6)和稳定期(OD600 =1.5- 1.6)的GAS,分别测定SEN和sGAPDH活性.同时用变溶菌素(mutanolysin)提取这2个生长阶段细胞壁结合蛋白,用Western blot检测该提取物中的SEN和sGAPDH.结果表明在相同菌细胞浊度的条件下,SEN在M6型GAS对数期时的表达量及活性比其稳定期时的高45％左右.虽然sGAPDH的表达量较高但活性很低(＜0.07mM NADH/min),并且在这2个生长阶段没有明显的差异. 相似文献

AIM: To investigate the effect of astragaloside IV on neurological function and the protein expression of neuron-specific enolase (NSE), Notch1 and NF-κB in acute cerebral hemorrhage (ACH) rats.METHODS: ACH model in rats was established via injection of autologous blood, and the rats were divided into 4 groups:sham, ACH, ACH+astragaloside IV (100 mg/kg) and ACH+astragaloside IV (200 mg/kg) groups. The impairment of neurological function in each group was graded, and the brain coefficient and water content were calculated. The serum level of NSE was measured by ELISA. Additionally, the expression of Notch1 and NF-κB was determined by Western blot.RESULTS: Astragaloside IV improved the neurological function and decreased the brain coefficient and water content in ACH rats. Moreover, the ACH-induced increase in NSE was inhibited after astragaloside IV treatment. Similarly, astragaloside IV also significantly attenuated the expression of Notch1 and NF-κB in ACH rats.CONCLUSION: Astragaloside IV attenuates the impairment of neurological function in ACH rats, which may be through decreasing the NSE level and down-regulating the expression of Notch1 and NF-κB. 相似文献

Diseases which cause skeletal muscle myopathy are some of the most economically damaging diseases in Atlantic salmon, Salmo salar L., aquaculture. Despite this, there are limited means of assessing fish health non‐destructively. Previous investigation of the serum proteome of Atlantic salmon, Salmo salar L., during pancreas disease (PD) has identified proteins in serum that have potential as biomarkers of the disease. Amongst these proteins, the enzyme enolase was selected as the most viable for use as a biomarker of muscle myopathy associated with PD. Western blot and immunoassay (ELISA) validated enolase as a biomarker for PD, whilst immunohistochemistry identified white muscle as the source of enolase. Enolase was shown to be a specific marker for white muscle myopathy in salmon, rising in serum concentration significantly correlating with pathological damage to the tissue. 相似文献

AIM: To explore the character of CD8 after traumatic brain injury (TBI) in peripheral blood. METHODS: Improved Feeney's free-fall method was used to set up traumatic brain injury model. The levels of neuron-specific enolase (NSE) and CD8 in the serum of the rats were detected by ELISA. The correlation of both NSE and CD8 in the serum was analyzed by Pearson product-moment correlation. The FasL expression in the lymphocytes of peripheral blood was determined by Western blot. RESULTS: The elevated level of CD8 lagged behind the level of NSE in the serum after TBI. The serum level of NSE was significantly increased at the 1st day after TBI and reached a peak at the 3rd day, subsequently gradually decreased to a lower level; the serum level of CD8 was increased at the 3rd day after TBI, and reached a peak at the 7th day, then gradually decreased. The serum levels of NSE at 1st, 3rd and 7th days were positively correlated with the serum level of CD8 at 3rd, 7th and 14th days. However, the FasL expression in the CD8+ lymphocytes of peripheral blood showed no variation at different time points after TBI. CONCLUSION: NSE in the serum released from neural tissues after TBI stimulates immune response and induces the augmentation of CD8 in peripheral blood, which may be a cause of secondary injuries in the brain. 相似文献
