    • 摘要: 从西沙永乐群岛7个岛礁海域的海水中分离出47株弧菌,将47株菌株进行16S rDNA、HSP60和gyrB扩增,序列在Genebank中进行比对,构建系统发育树。结果显示利用16S rDNA和HSP60序列比对均无法鉴定弧菌到种。gyrB 1和gyrB 2引物均只能扩增出6株菌株的目标序列,gyrB 3引物能扩增47株菌株的目标序列,且成功构建系统发育树,可鉴定弧菌到种。47株弧菌菌株分属于7个种,鸭公岛弧菌多样性最丰富,可分离到5种;石屿和羚羊礁筐仔沙洲弧菌多样性最低,均只分离到2种。本研究建立了可靠的海洋弧菌的分子鉴定方法,获得的菌株丰富了南海微生物菌种库,可为今后的研究与教学提供材料。

    • 摘要: Diapause is a long-lived stage which has evolved into an important strategy for insects to circumvent extreme environments.In the pupal stage,Helicoverpa armigera can enter diapause,a state characterized by significantly decreased metabolic activity and enhanced stress resistance,to survive cold winters.Previous studies have shown that reactive oxygen species(ROS)can promote the diapause process by regulating a distinct insulin signaling pathway.However,the source of ROS in the diapause-destined pupal brains and mechanisms by which ROS regulate diapause are still unknown.In this study,we showed that diapause-destined pupal brains accumulated high levels of mitochondrial ROS(mtROS)and total ROS during the diapause process,suggesting that mitochondria are the main source of ROS in diapause-destined pupal brains.In addition,injection of 2-deoxy-D-glucose(DOG),a glucose metabolism inhibitor,could delay pupal development by elevating mtROS levels in the nondiapause-destined pupal brains.Furthermore,the injection of a metabolite mixture to increase metabolic activity could avert the diapause process in diapause-destined pupae by decreasing mtROS levels.We also found that ROS could activate HSP60 expression and promote the stability of the HSP60-Lon complex,increasing its ability to degrade mitochondrial transcription factor A(TFAM)and decreasing mitochondrial activity or biogenesis under oxidative stress.Thus,this study illustrated the beneficial function of ROS in diapause or lifespan extension by decreasing mitochondrial activity.

    • 摘要: 目的 观察针灸对脑梗死大鼠HSP60、Caspase-3表达规律,初步探讨针灸对缺血性脑卒中大鼠神经细胞凋亡保护的作用机制.方法 采用大脑中动脉线栓诱导脑缺血再灌注损伤模型,随机假手术组、模型组、电针穴位组、电针非经非穴和艾灸穴位组.电针或艾灸干预后,术后0、12h评估大鼠的神经功能缺陷评分和姿势反射评分;荧光定量PCR检测HSP60和Caspase-3 mRNA的表达水平.结果 电针穴位组、艾灸穴位组大鼠神经功能均优于模型组,差异有统计学意义(P<0.05);与模型组比较,电针穴位组大鼠HSP60 mRNA显著增加,差异有显著性意义(P<0.05);而Caspase-3 mRNA表达无明显变化.结论 电针对大鼠脑缺血再灌注损伤神经功能有改善作用,其机制可能与上调脑组织中HSP60表达,介导抗神经细胞凋亡有关.

    • 摘要: 目的 探讨Neuritin与HSP60在肝损伤修复过程中的表达变化以及可能的分子机制,为研究肝损伤修复提供实验基础.方法 将48只Sprague-Dawley(SD)大鼠,随机分为空白组(n=6)和实验组(n=42),空白组不做任何处理,实验组均行70%肝左叶切除以诱导急性肝损伤,并于术后6、12、24、48 h和3、7、14 d再次切除残余肝左叶,采用免疫印迹技术(Western blot)检测Neuritin与HSP60在相应时间点肝组织中的表达变化差异,行苏木精-伊红染色(HE)观察各时间点肝脏病理学改变,同时于尾缘静脉采血检测ATL和AST水平变化.结果 (1)与空白组相比,实验组于术后6、12、24、48 h血清ALT、AST含量持续增高并于48 h达到高峰,3 d开始降低、7 d几乎接近正常,差异具有统计学意义(P<0.05).病理学提示:与空白组相比,实验组肝小叶结构排列紊乱,气球样变明显,在术后48 h最为明显;(2)在肝损伤修复的整个过程中,Neuritin与HSP60的表达变化呈现截然相反的差异,Neuritin的表达与肝损伤的加重或修复存在显著的负相关性(P<0.001),并且在肝损伤最重的48 h时其表达量最低;HSP60的表达与肝损伤的加重或修复存在显著的正相关性(P<0.001),并且在肝损伤最重的48 h时其表达量最高.结论 (1)采用单纯性70%肝左叶切除术,成功建立了SD大鼠的肝损伤修复模型,其损伤在术后第48小时最重,该方法造模成功率为100%(42/42),操作简单、实用性强,为研究肝再生、肝损伤、肝移植等提供了一种可靠且简便的动物模型;(2)Neuritin的表达在肝损伤后逐渐降低,并在第48小时达到最低,而HSP60的表达逐渐升高,并在第48小时达到最高;(3)Neuritin与HSP60的表达变化与肝损伤修复过程密切相关(P<0.001),呈现出一定变化规律,两者可能通过某种相互作用而产生相应的生物效应,共同参与并促进了肝损伤的再生修复.%Objective To explore the expression changes and possible molecular mechanisms of Neuritin and HSP60 during the repair of liver injury,and to provide an experimental basis for the study of the repair of liver injury. Methods Forty-eight Sprague-Dawley(SD)rats were randomly divided into control group without any treatment(n=6)and experimental group(n=42)underwent 70% hepatectomy to induce acute liver injury,and 6 h,12 h,24 h,48 h,3 d,7 d and 14 d after the operation,the left lobe resection of the residual liver was per-formed. Immunoblotting technique (Western blot) was used to detect the expression difference of Neuritin and HSP60 in liver tissue of the corresponding time points. Hematoxylin eosin staining(hematoxylin-eosin staining, HE)was used to observe the expression changes at each time point in liver pathology,and tail vein blood to detect ATL and AST changes. Results (1)Compared with those in the control group,the serum ALT and AST levels in the experimental group were increased at 6 h,12 h,24 h and 48 h after the operation,and reached the peak at 48 h postoperatively but those began to decrease 3 d postoperatively and was almost normal 7 d postoperatively. The difference was statistically significant(P < 0.05). Pathological findings:compared with that in the control group, the hepatic lobule structure in the experimental group was disorderly. The obvious balloon like change reached the peak 48 h postoperatively.(2)In the whole process of repair of liver injury,the expression of Neuritin and HSP60 showed differences in the opposite. There was a significantly negative correlation between Neuritin expression and the repair or the aggravation of the injury(P<0.001)and the lowest expression was observed 48 h postoperatively. There was a significantly positive correlation between HSP60 expression and the repair or the aggravation of the injury(P < 0.001)and the highest expression was observed 48 h postoperatively. Conclusions (1)With simple 70% left hepatic lobectomy,the repair of liver injury model of SD rats is successfully established and the heaviest injury is observed 48h postoperatively. With a high success rate(100%,42/42),simple and practical,the method provides a reliable and convenient animal model for the study of liver regeneration,liver injury and liver transplan-tation.(2)The expression of Neuritin decreases gradually after liver injury and reaches the lowest 48 h postopera-tively,while the expression of HSP60 increases gradually and reaches the highest 48 h postoperatively.(3)The change of expression of Neuritin and HSP60 is closely related to the process of liver injury repair(P < 0.001), showing a certain change rule. They may have some biological effects through interactions,and participate in and promote the regeneration and repair of liver injury.

    • 摘要: [目的]马铃薯甲虫Leptinotarsa decemlineata是一种世界性检疫害虫,对温度胁迫具有极强的适应性,为进一步明确其对温度胁迫适应性的分子机制,研究了热激蛋白HSP60在马铃薯甲虫温度胁迫应答过程中的作用.[方法]采用RT-PCR及RACE技术克隆马铃薯甲虫热激蛋白HSP60基因的cDNA全长序列;利用生物信息学软件分析该基因及其编码蛋白质的序列特性;运用实时荧光定量PCR技术分析该基因在温度胁迫下的表达模式.[结果]克隆得到马铃薯甲虫热激蛋白HSP60基因,命名为Ld-HSP60(GenBank登录号:KC556801),其cDNA全长2 234 bp,开放阅读框(ORF)长1 731 bp,编码576个氨基酸,相对分子量约为61.27 kD,理论等电点为5.51,5'端非翻译区(UTR)长101 bp,3'UTR长402 bp.氨基酸序列中含有HSP60家族典型的特征序列.实时荧光定量PCR结果表明,低温胁迫(-10和0°C)下未检测到马铃薯甲虫雌雄成虫中Ld-HSP60的诱导表达;高温胁迫(38和44°C)诱导马铃薯甲虫雄成虫Ld-HSP60上调表达,随着胁迫温度的升高Ld-HSP60表达量呈现先升高后降低的趋势,38°C高温胁迫下表达量最高,胁迫时间越长Ld-HSP60表达量也越高.[结论]相比其他热激蛋白,HSP60对温度敏感性较低,推测HSP60可能在马铃薯甲虫雄成虫抵御高温胁迫中发挥作用.%[Aim] As one of international major quarantine pests,the Colorado potato beetle,Leptinotars decemlineata,has strong resistance to temperature stress.The study aims to better understand the molecular mechanism of resistance to temperature stress in L.decemlineata by determining the role of heat shock protein HSP60 in response to temperature stress in this beetle.[Methods] The full-length cDNA encoding HSP60 from L.decemlineata was cloned by RT-PCR and RACE technologies.Bioinformatics programs were used to analyze the sequence characteristics of the gene and amino acid sequence.The mRNA expression levels of the gene in L.decemlineata under cold and heat stress conditions were detected by real-time PCR.[Results] The complete cDNA of the gene encoding heat shock protein HSP60 was obtained from L.decemlineata,and named Ld-HSP60 with the GenBank accession no.of KC556801.The complete cDNA (2 234 bp) is comprised of a 101 bp 5'untranslated region (UTR),a 402 bp 3'UTR,and a 1 731 bp open reading frame (ORF).The ORF of Ld-HSP60 encodes a protein of 576 amino acids,with the molecular weight of 61.27 kD and the theoretical pI of 5.51.The mature amino acid sequence contains the classical signature sequences of HSP60 family.The real-time PCR results showed that low temperature stress (-10 and 0°C) did not induce the expression of Ld-HSP60 in male and female adults of L.decemlineata;however,high temperature stress (38 and 44°C) induced the up-regulated expression of Ld-HSP60 in male adults,and the expression trend of Ld-HSP60 rose first and then fell with the increasing temperature.The expression level of Ld-HSP60 reached the maximum at 38°C,and the longer the stress time the higher the expression level.[Conclusion] HSP60 is less sensitive to temperature than other heat shock proteins,and it is inferred that HSP60 may play a role in resistance to high temperature stress in male adults of L.decemlineata.
