MicroRNAs were associated with the development and progression of glaucoma. The cellular machinery processes the latter into siRNA in vivo. Their structure has modifications so as. to reduce unspecific staining after hybridization you could use RNase A to remove unbound probe (also removing un-incorporated nucleotides by column purification could help) quality of the RNase. A region of ~600bp encompassing each miRNA is cloned downstream of a CMV. ( b) Exogenous expression of miR. Other than changes in specific miRNA levels, the dysregulated expression of miRNA biogenesis-associated nucleases Drosha and Dicer has been linked to cancer [15,16]. They are based on three RNA strands, rather than the two RNA strands that characterize traditional miRNA mimics. Artificial miRNA (amiRNA) technology uses endogenous pri-miRNAs, in which the miRNA and miRNA* (passenger strand of the miRNA duplex) sequences have been replaced with corresponding amiRNA/amiRNA* sequences that direct highly efficient RNA silencing of the targeted gene.
