Construction of lentiviral vector carrying Rab9 gene and its expression in mouse brain

Youguo HAO, Min ZHANG, Jinzhi XU, Bitao BU, Jiajun WEI

Frontiers of Medicine 2009, Volume 3, Issue 2,   Pages 141-147 doi: 10.1007/s11684-009-0041-6

Abstract: Rab proteins and their effectors facilitate vesicular transport by tethering donor vesicles to their respective target membranes. Rab9 mediates late endosome-to- -Golgi-network trafficking. To explore the possibility of Rab9-related gene therapy for neurodegenerative diseases, we packed Lentivirus encoding Rab9. The expressing plasmid pCDH1-MCF1-Rab9-EF1-copGFP was constructed by using molecular biological techniques. The Lentivirus encoding Rab9 cDNA was packed by Lifectamine-2000 mediated co-transfection of the plasmid pPACKH1- , pPACKH1- and pVSV- into 293T cells. DNA sequencing proved the successful construction of pCDH1-MCF1-Rab9-EF1-copGFP. After 72 hours, the expression of GFP could be detected in BV-2 cells. Western blotting revealed that the Rab9 gene expression in BALB/c mice brain was up-regulated significantly 4 weeks after injection with Lentivirus encoding Rab9, which evidenced a satisfactory increasing effect of this virus. Administration of Lenti-Rab9 to postnatal day 3 Niemann-Pick disease type C (NPC) mice reduced motor defects and prevented the weight loss associated with female NPC mice, as well as modulating the death rate of Purkinje neurons. It is concluded that the packaging of Lentivirus encoding Rab9 was successful. Lentivirus encoding Rab9 can increase the expression of Rab9 gene effectively, which might offer a novel means for the treatment of neurodegenerative diseases.

Sustainability of urban drainage management: a perspective on infrastructure resilience and thresholds

Xiong NING, Yi LIU, Jining CHEN, Xin DONG, Wangfeng LI, Bin LIANG

Frontiers of Environmental Science & Engineering 2013, Volume 7, Issue 5,   Pages 658-668 doi: 10.1007/s11783-013-0546-8

Abstract: Urban wastewater infrastructures have been threatened by natural and socioeconomic disturbances. This study investigates infrastructure resilience against the risks of long-term changes rather than natural disasters. Urban expansion that leads to an increased urban runoff and massive population movements that cause fluctuations in domestic emissions are considered in this study. Pollution permits for water bodies are adopted as constraints on wastewater infrastructures. A land use-based accounting method, combined with a grid-based database, is developed to map domestic discharge and urban runoff to service areas of wastewater treatment plants. The results of a case study on downtown Sanya, the most famous seashore tourist attraction in China, show that the average resilient values of three sub-catchment areas in 2010 were -0.57, 0.10 and 0.27, respectively, a significant spatial variation. The infrastructure in the Sanya River sub-region is the least flexible, and is more likely to fail due to unstable inflows. The resiliencies will increase to 0.59, 1.01 and 0.54, respectively, in 2020, a considerable improvement in robustness. The study suggests that infrastructure resilience needs to be taken into further consideration for urban planning and the related realm of urban governance to foster more robust wastewater management under various risks.
