| 1 | Inhibiting effect of antisense oligonucleotides phosphorthioate on gene expression of TIMP-1 in rat liver fibrosis显示文摘AIM To observe the inhibition of antisenseoligonucleotides (asON) phosphorthioate to thetissue inhibitors metalloproteinase-1 (TIMP-1)gene and protein expression in the liver tissue ofimmunologically induced hepatic fibrosis rats.The possibility of reversing hepatic fibrosisthrough gene therapy was observed.METHODS Human serum albumin (HSA) wasused to attack rats, as hepatic fibrosis model, inwhich asONs were used to block the gene andprotein expressing TIMP-1. According to theanalysis of modulator, structure protein, codingseries of TIMP-1 genome, we designed fourdifferent asONs. These asONs were injected intothe hepatic fibrosis models through coccygealvein. The results was observed by RT-PCR formeasuring TIMP-1 mRNA expression,immunohistochemistry and in situ hybridizationfor collagen Ⅰ, Ⅲ, special staining of collagenfiber, and electron microscopic examination.RESULTS Hepatic fibrosis could last within 363days in our modified model. The expressinglevel of TIMP-1 was high during hepatic fibrosisprocess. It has been proved by theimmunohistochemical and the electronmicroscopic examination that the asONphosphorthioate of TIMP-1 could exactly expressin vivo. The effect of colchicine wasdemonstrated to inhibit the expressing level ofmRNA and the content of collagen Ⅰ, Ⅲ in theliver of experimental hepatic fibrosis rats.However, the electron microscopy research andthe pathologic grading of hepatic fibrosisshowed that there was no significant differencebetween the treatment group and the modelgroup (P>0.05).CONCLUSION The experimental rat model ofhepatic fibrosis is one of the preferable modelsto estimate the curative effect of anti-hepaticfibrosis drugs. The asON phosphorthioate ofTIMP-1 could block the gene and proteinexpression of TIMP-1 in the liver of experimentalhepatic fibrosis rats at the mRNA level. It ispossible to reverse hepatic fibrosis, and it isexpected to study a new drug of anti-hepaticfibrosis on the genetic level. Colchicine has verylimited therapeutic effect on hepatic fibrosis,furthermore, its toxicity and side effects areobvious. | Qing He Nie Yong Qian Cheng Yu Mei Xie Yong Xing Zhou Yi Zhan Cao The Center of Infectious Disease Diagnosis and Treatment of PLA,Tangdu Hospital,Forth Military Medical University,Xi’an 710038,Shaanxi Province,ChinaDr,Qing He Nie graduated from Qinghai Medical College as a doctor in 1983,got master degree at Beijing 302 Army Hospital in 1993,got doctor degree at the Third Military Medical University in 1998,engaged in postdoctoral research at the Fourth Military Medical University from 1998 to 2000,now an associate professor,specialized in clinical and experimental research of infectious diseases,had more than 90 papers published,coauthor of ten books,first author of one book. | 2001 | World Journal of Gastroenterology2001,7,3: | 73 |

| 3 | Current progress in epigenetic research for hepato-carcinomagenesis显示文摘Hepatocellular carcinoma is the main type of primary liver cancer,and also one of the most malignant tumors.At present,the pathogenesis mechanisms of liver cancer are not entirely clear.It has been shown that inactivation of tumor suppressor genes and activation of oncogenes play a significant role in carcinogenesis,caused by the genetic and epigenetic aberrance.In the past,people generally thought that genetic mutation is a key event of tumor pathogenesis,and somatic mutation of tumor suppressor genes is in particular closely associated with oncogenesis.With deeper understanding of tumors in recent years,increasing evidence has shown that epigenetic silencing of those genes,as a result of aberrant hypermethylation of CpG islands in promoters and histone modification,is essential to carcinogenesis and metastasis.The term epigenetics refers to heritable changes in gene expression caused by regulation mechanisms,other than changes in the underlying DNA sequence.Specific epigenetic processes include DNA methylation,genome imprinting,chromotin remodeling,histone modification and microRNA regulations.This paper reviews recent epigenetics research progress in the hepatocellular carcinoma study,and tries to depict the relationships between hepatocellular carcinomagenesis and DNA methylation as well as microRNA regulation. | HUANG Jian National Human Genome Research Center at Shanghai-Ministry of Science and Technology to build a healthy and disease Ge-nomics Laboratory,Shanghai 201203,China | 2009 | Science China(Life Sciences)2009,52,1: | 9 |

| 10 | Evidence of increasing L1014F kdr mutation frequency in Anopheles gambiae s.l.pyrethroid resistant following a nationwide distribution of LLINs by the Beninese National Malaria Control Programme显示文摘Objective:To determine the susceptibility status to pyrethroid in Anopheles gambiae s.l.(An.gambiae),the distribution of kdr'Leu-Phe'mutation in malaria vectors in Benin and to compare the current frequency of kdr'Leu-Phe'mutation to the previous frequency after long-lasting insecticide treated nets implementation.Methods:Larvae and pupae of An.gambiae s.l.mosquitoes were collected from the breeding sites in Littoral,Zou.Borgou and Alibori provinces.CDC susceptibility tests were conducted on unfed females mosquitoes aged 2-5 d old.An.gambiae mosquitoes were identified to species using PCR techniques.Molecular assays were also carried out to identify kdr mutations in individual mosquitoes.Results:The results showed that An.gambiae Malanville and Suru-lere populations were resistant to deltamethrin.Regarding An.gambiae Parakou and Bohicon populations,they were resistant to permethrin.PCR revealed 100%of mosquitoes tested were An.gambiae s.s.The L1014F kdr mutation was found in An.gambiae s.s.Malanville and Parakou at various allelic frequencies.The increase of kdr allelic frequency was positively correlated with CDC bioassays data.Conclusions:Pyrethroid resistance is widespread in malaria vector in Benin and kdr mutation is the main resistance mechanism involved.More attention may be paid for the future success of malaria control programmes based on LLINs with pyrethroids in the country. | Nazairc Azoun Rock Akpon Martin Akogbéto | 2014 | Asian Pacific Journal of Tropical Biomedicine2014,4,3: | 2 |
