Abstract:
Surface-rigidified cerasomes (ceramic-coated liposomes) are neither fused nor cross-linked when bound to siRNA (short duplex RNA) but not to plasmid DNA (long duplex DNA) which induces cross-linking. Non-ceramic reference liposomes are easily fused by the siRNA. The cerasome can thus be used as a viral-size siRNA-carrier in a wide range of concentration for RNAi silencing of exogenous and endogenous genes.

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...
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...
