Regulation of interferon and retinoic acid-induced cell death activation through thioredoxin reductase.
Interferons (IFNs) and retinoids are potent biological response modifiers. The IFN-beta and all-trans-retinoic acid combination, but not these single agents individually, induces death in several tumor cell lines. To elucidate the molecular basis for these actions, we have employed an antisense knockout approach to identify the gene products that mediate cell death and isolated several genes as...
متن کاملInduction of thioredoxin and thioredoxin reductase gene expression in lungs of newborn primates by oxygen.
Thioredoxin (TRX) is a potent protein disulfide oxidoreductase important in antioxidant defense and regulation of cell growth and signal transduction processes, among them the production of nitric oxide. We report that lung TRX and its reductase, TR, are specifically upregulated at birth by O2. Throughout the third trimester, mRNAs for TRX and TR were expressed constitutively at low levels in f...
متن کاملNADPH-Dependent Thioredoxin Reductase and a New Thioredoxin from Wheat
An albumin fraction extracted from wheat flour contains thioredoxin reductase (Mr = 65,000) and a heat-stable thioredoxin (Mr = 15,000) which are separated on DEAE cellulose and further purified by gel filtration. W heat thioredoxin stimulates E. coli ribonucleotide reductase but not chloroplast fructose-bis-phosphatase. The enzyme is NADPH-dependent (Km = 3.2 X 10 -6 m) . In presence of the th...
متن کاملEffects of redox modulation by inhibition of thioredoxin reductase on radiosensitivity and gene expression
The thioredoxin system is a promising target when aiming to overcome the problem of clinical radiation resistance. Altered cellular redox status and redox sensitive thiols contributing to induction of resistance strongly connect the ubiquitous redox enzyme thioredoxin reductase (TrxR) to the cellular response to ionizing radiation. To further investigate possible strategies in combating clinica...
متن کاملThe thioredoxin-thioredoxin reductase system: over-expression in human cancer.
Redox control has emerged as a fundamental biological control mechanism. One of the major redox control systems is the thioredoxin system comprised of thioredoxin (TRX) and thioredoxin reductase (TR). Together they form a powerful system involved in many central intracellular and extracellular processes including cell proliferation, the redox regulation of gene expression and signal transductio...
