BACKGROUND Thioredoxin h (trx h) is closely related to germination of cereal seeds. The cDNA sequences of the thioredoxin s (trx s) gene from Phalaris coerulescens and the thioredoxin h (trx h) gene from wheat are highly homologous, and their expression products have similar biological functions. Transgenic wheat had been formed after the antisense trx s was transferred into wheat, and it had b...

The products of the trithorax gene are required to stably maintain homeotic gene expression patterns established during embryo-genesis by the action of the transiently expressed segmentation genes. We have determined the intron/exon structure of the trx gene and the large alternatively spliced trx RNAs, which are capable of encoding only two protein isoforms. These very large trx proteins diffe...

Exposure to excessive light induces retinal photoreceptor cell damage, leading to development and progression of various retinal diseases. We tested the effect of geranylgeranylacetone (GGA), an acyclic polyisoprenoid, on light-induced retinal damage in mice. Oral treatment with GGA (1.0 mg/d) for 5 d induced thioredoxin (Trx) and heat shock protein 72 (Hsp72) predominantly in the retinal pigme...

Thioredoxin (TRX), a disulfide-reducing intracellular protein, functions as a cellular defense mechanism against oxidative stress. In this study, we asked whether expression of TRX, glutathione-thiol transferase pi, and high mobility group protein 1 (HMG-1) genes is enhanced in human hepatocellular carcinoma and whether expression of these genes is associated with sensitivity to cisplatin. Both...

Insect antimicrobial peptides (AMPs) have a broad antimicrobial spectrum. To aid the characterization of the gene function and further applications, we cloned the gene of cecropinXJ into the prokaryotic expression vector pET32a and expressed cecropinXJ in Escherichia coli BL2l (DE3). Following induction by isopropyl-β-D-thiogalactoside (IPTG), a 25 kDa fusion peptide of cecropinXJ with a tagged...

Thioredoxin (TRX-1) is a multifunctional protein that controls the redox status of other proteins. TRX-1 can be found in the extracellular milieu, cytoplasm and nucleus, and it has distinct functions in each environment. Previously, we studied the intracellular localization of TRX-1 and its relationship with the activation of the p21Ras-ERK1/2 MAP Kinases signaling pathway. In situations where ...

A large amount of money in the economy remains form trade receivables that are created from business to (B2B) transactions among firms. There 7.818 million firms Bangladesh and 99% them categories cottage, micro, small, medium enterprises (CMSMEs). They supply raw materials, semi-finished goods, services on credit blue-chip corporate manufacturers. CMSMEs generally wait for a period 30 days, 60...

Thioredoxin (TRX) is a cytoplasmic, redox-sensitive signaling factor believed to participate in the regulation of nuclear transcription factors mediating cellular responses to environmental stress. Activation of the activator protein (AP)-1 transcription factor is thought to be mediated in part by redox-sensitive interactions between the nuclear signaling protein redox factor-1 (Ref-1) and TRX....

In order to analyze the effect of OC kappa in redox status, photosynthesis, basal metabolism and growth in Eucalyptus globulus, trees were treated with water (control), with OC kappa at 1 mg mL(-1), or treated with inhibitors of NAD(P)H, ascorbate (ASC), and glutathione (GSH) syntheses and thioredoxin reductase (TRR) activity, CHS-828, lycorine, buthionine sulfoximine (BSO), and auranofin, resp...
