the thioredoxin system, comprising thioredoxin (trx), thioredoxin reductase (trxr) and nadph, is one of the major cellular antioxidant systems, implicated in a large and growing number of biological functions. trx acts as an oxidoreductase via a highly conserved dithiol/disulfide motif located in the active site ( trp-cys-gly-pro- cys-lys-). different factors are involved in the regulation of t...

exosomes, as a mediator of cell-to-cell transfer of genetic information, act an important role in intercommunication between tumor cells and their niche including fibroblasts, endothelial cells, adipocytes and monocytes. several studies have shown that tumor cells can influence their neighboring cells by releasing exosomes. these exosomes provide signaling cues for stimulation, activation, prol...

Context:MicroRNAs (miRNAs) are a class of short, endogenously-initiated, non-coding RNAs that post-transcriptionally control gene expression via translational repression or mRNA turnover. MiRNAs have attracted much attention in recent years as they play critical roles in gene expression and are promising tools with many biotech and therapeutic applications. The molecular mechanisms und...
