MicroRNA (miRNA) are small, non-coding RNA that directly regulate gene expression by binding to messenger RNA transcripts. Pre-miRNA (precursor microRNA) is processed by Drosha, a nuclear RNase III enzyme, and is exported to the cytoplasm. Corresponding siRNAs can then be chemically synthesized, created by in vitro transcription, or expressed from a vector or PCR product. Figure 3. The primer can be elongated with a tail of The stem-loop RT primer provides the specificity for the mature miRNA target; it does not detect its precursor. MicroRNA Targeting. . Precise and sensitive analysis of exosomal microRNA (miRNA) is of great importance for noninvasive early disease diagnosis, but it remains a great challenge to detect exosomal miRNA in human blood samples because of their small size, high sequence homology, and low abundance. It accepts a short DNA sequence (<= 30 mer), and returns a scrambled sequence. Accumulation of 4-HNE protein adducts has been reported in several cardiovascular diseases, such as myocardial infarction, hypertension and heart failure in both rodents and humans.
