“…For detection of mRNA, total RNA from cells was extracted using miRVana miRNA isolation kit according to the manufacturer's protocol (Ambion, Life Technologies, Grand Island, NY). For mRNA expression studies, cDNA synthesis was achieved by a SuperScript III first-strand synthesis system (Applied Biosystems, Life Technologies) as described (16). The abundance of mRNA for genes of interest was quantified by using real-time polymerase chain reaction (PCR) with double-stranded DNA binding dye SYBR green-I.…”

forming endothelial cells have highly elevated levels of Nox-4 that release H2O2 into the nucleus, which is generally not compatible with cell survival. We sought to identify compensatory mechanisms that enable tumorforming endothelial cells to survive and proliferate under these conditions. Ape-1/ref-1 (Apex-1) is a multifunctional protein that promotes DNA binding of redox-sensitive transcription factors, such as AP-1, and repairs oxidative DNA damage. A validated mouse endothelial cell (EOMA) tumor model was used to demonstrate that Nox-4-derived H 2O2 causes DNA oxidation that induces Apex-1 expression. Apex-1 functions as a chaperone to keep transcription factors in a reduced state. In EOMA cells Apex-1 enables AP-1 binding to the monocyte chemoattractant protein-1 (mcp-1) promoter and expression of that protein is required for endothelial cell tumor formation. Intraperitoneal injection of the small molecule inhibitor E3330, which specifically targets Apex-1 redox-sensitive functions, resulted in a 50% decrease in tumor volume compared with mice injected with vehicle control (n ϭ 6 per group), indicating that endothelial cell tumor proliferation is dependent on Apex-1 expression. These are the first reported results to establish Nox-4 induction of Apex-1 as a mechanism promoting endothelial cell tumor formation.

MicroRNA plays important regulatory roles on the genetic network which provides researchers with valuable novel mechanistic directions and perspectives for applications in a wide variety of fields. Despite pertinent insight gained from messenger RNA, microRNAs possess distinct biochemical properties that emphasize the need for independent research to be conducted that addresses specifically microRNA handling. This review provides a brief summary on the various factors at post-sample harvesting stages with focus on microRNA from cellular, tissue, plasma and serum samples. It incorporates an up-to-date discussion on the isolation methods, quality control, profiling methods and other post-harvesting factors in microRNA research.
