Many studies reported that redox enzymes, particularly thioredoxin and peroxiredoxin, can be released by cells act as soluble mediators in immunity. Recently, it became clear peroxiredoxins secreted via the exosome-release route, yet remains unclear how this exactly happens why. This review will first introduce briefly possible states of protein cysteines role enzymes their regulation. We then ...

MicroRNAs (miRNAs) are an evolutionarily conserved class of small, regulatory non-coding RNAs that negatively regulate protein coding gene and other non-coding transcripts expression. miRNAs have been established as master regulators of cellular processes, and they play a vital role in tumor initiation, progression and metastasis. Further, widespread deregulation of microRNAs have been reported...

In the past few years, the crucial role of different micro-RNAs (miRNAs) in the cardiovascular system has been widely recognized. Recently, it was discovered that extracellular miRNAs circulate in the bloodstream and that such circulating miRNAs are remarkably stable. This has raised the possibility that miRNAs may be probed in the circulation and can serve as novel diagnostic markers. Although...

Micro RNAs (miRNAs) regulate gene expression at the posttranscriptional level. Here we show that regulatory T (T reg) cells have a miRNA profile distinct from conventional CD4 T cells. A partial T reg cell-like miRNA profile is conferred by the enforced expression of Foxp3 and, surprisingly, by the activation of conventional CD4 T cells. Depleting miRNAs by eliminating Dicer, the RNAse III enzy...

microRNAs (miRNAs) are a new class of non-protein-coding, endogenous, small RNAs. They are important regulatory molecules in animals and plants. miRNA regulates gene expression by translational repression, mRNA cleavage, and mRNA decay initiated by miRNA-guided rapid deadenylation. Recent studies show that some miRNAs regulate cell proliferation and apoptosis processes that are important in can...

Background: Absent in Melanoma 2 (AIM2) is an intracellular microbial dsDNA sensor which plays an important role in production of proinflammatory cytokines through Apoptosis associated Speck-like protein containing a Caspase activation and recruitment domain (ASC) and Caspase-1. Micro-RNAs (miRNAs) play important roles in regulation of immune related genes. However, there is little information ...

Breast cancer progression including bone metastasis is a complex process involving numerous changes in gene expression and function. MicroRNAs (miRNAs) are small endogenous noncoding RNAs that regulate gene expression by targeting protein-coding mRNAs posttranscriptionally, often affecting a number of gene targets simultaneously. Alteration in expression of miRNAs is common in human breast canc...

Background Left ventricular hypertrophy (LVH) is a common presentation among hypertensive patients. Micro-RNAs (miRNAs) have been proven to show reproducible dysregulations in hypertrophied cardiac tissues. Three miRNAs, miR-133, miR-155, and miR-195 were used in the study to elucidate the miRNA expression anomaly in heart diseases. MiR-133 and miR-195 have been reported as two highly expressed...

Avian leukosis is a neoplastic disease caused in part by subgroup J avian leukosis virus J (ALV-J). Micro ribonucleic acids (miRNAs) play pivotal oncogenic and tumour-suppressor roles in tumour development and progression. However, little is known about the potential role of miRNAs in avian leukosis tumours. We have found a novel tumour-suppressor miRNA, gga-miR-375, associated with avian leuko...
