방법을 이용하여 행하여졌으며, 형질전환된 담배세포는 항생물질 저항성 배지에서의 callus 형성 여부로 선별되었고, 선별된 형질전환된 calli는 shoot와 root 형성을 위해 적절한 MS agar 배지에서 계속 키워졌다. 이와 같이 형질전환된 담배세포에서 완전한 식물체로 재생된 담배잎에서의 E. coli thioredoxin 유전자의 발현을 조사한 결과 thioredoxin 활성이 형질전환된 담배세포가 정상세포에 비해 9배 정도 더 큰 것으로 나타났다. 이러한 일련의 결과들은 E. coli thioredoxin 유전자가 성공적으로 담배세포에 들어가서 높은... -

plasmid를 vector로 이용한 외래 유전자의 도입이 활발히 진행되고 있다. 본 연구에서는 Ti plasmid vector의 일종인 pGA658을 이용하여 광합성 조절 등 여러가지 기능을 갖고 있는 것으로 알려져 있는 thioredoxin 유전자를 식물체내로 도입하여 식물체내에서의 그 역할을 조사할 목적으로 DNA 재조합을 시도하였다. E. coli thioredoxin 유전자를 함유하는 pCJF 4의 Hind III-BamHI DNA fragment를 pGA658의 Hind III-Bgl II site에 삽입시키고 E. coli에 transformation 한 후 형질전환체의 확인은 항생물질 marker에 대한 저항성으로,... -
Altered expression of thioredoxin reductase-1 in dysplastic bile ducts and cholangiocarcinoma in a hamster model

Thioredoxin reductase 1 (TrxR) is a homodimeric selenoenzyme catalyzing thioredoxin (Trx) in an NADPHdependent manner. With regard to carcinogenesis, these redox proteins have been implicated in cell proliferation, transformation and anti-apoptosis. In the present study, using a hamster cholangiocarcinoma (ChC) model, we evaluated the immunohistochemical expression pattern of TrxR in precancerous lesions and ChCs as well as in normal bile ducts. The goal of this study was to determine the... -

of toxic chemicals. Thioredoxin (Trx) family proteins are known to play protective roles in organisms under oxidative stress through redox reaction by using reducing equivalents of cysteines at a conserved active site, Cys-X-X-Cys. Whereas biological and physiological properties of Trx1 are well characterized, significance of mitochondrial thioredoxin (Trx2) is not well known. Therefore, we addressed physiological role of Trx2 in PC12 cells under oxidative stress. In PC12 cells, transiently... -

promising approach to control plant viruses in their insect vectors. In the present study, to suppress replication of the rice stripe virus (RSV) in its vector, Laodelphax striatellus, using RNAi, dsRNAs against L. striatellus genes that are strongly upregulated upon RSV infection were delivered through a rice leaf-medi- ated method. RNAi-based silencing of peroxiredoxin, cathepsin B, and cytochrome P450 resulted in significant down regulation of the NS3 gene of RSV, achieving a transcriptional... -

Treadmill exercise prevents diabetes-induced increases in lipid peroxidation and decreases in Cu,Zn-superoxide dismutase levels in the hippocampus of Zucker diabetic fatty rats

In the present study, we investigated the effects of treadmill exercise on lipid peroxidation and Cu,Zn-superoxide dismutase (SOD1) levels in the hippocampus of Zucker diabetic fatty (ZDF) rats and lean control rats (ZLC) during the onset of diabetes. At 7 weeks of age, ZLC and ZDF rats were either placed on a stationary treadmill or made to run for 1 h/day for 5 consecutive days at 16∼22 m/min for 5 weeks. At 12 weeks of age, the ZDF rats had significantly higher... -

a portion of the highly soluble bacterial protein thioredoxin (TRX). TRX-gp91(phox) (306-569), which contains the putative FAD and NADPH binding sites, showed NADPH-dependent NBT (nitroblue tetrazolium) reductase activity, whereas TRX-gp91(phox) (304-423) and TRX-gp91(phox) (424-569) were inactive. Activity saturated at about a 1:1 molar ratio of FAD to TRX-gp91(phox) (306- 569), and showed the same Km for NADPH as that for superoxide generating activity by the intact enzyme. Activity was not... -
