Abstract:
Antisense oligonucleotides (AS ONs) selectively bind to the target mRNA and prevent its translation into the corresponding protein. Various tissue culture studies demonstrated that AS ONs enter into cells via the receptor-mediated endocytosis pathway. There are many different types of receptors, and their characteristics and expression vary with cell types. In this review, we will discuss the characteristics of the various receptors that have been isolated in vitro. We will also discuss the uptake and the bioavailability of AS ONs after being administered in vivo.

RNA Interference
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
siRNA - Small Interfering RNAs
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the ATP-dependent...
