Down-regulation of human deoxyuridine triphosphate nucleotidohydrolase (dUTPase) using small interfering RNA (siRNA)
1Department of Molecular Virology, Immunology and Medical Genetics, The Ohio State University, Columbus, Ohio 43210, USA.
Abstract:
A small interfering double stranded RNA molecule (siRNA, 21 bp) corresponding to a portion (nucleotides 337 to 357) of domain 3 of the human dUTPase was synthesized and used to determine whether it could down-regulate dUTPase activity in human cells. Transfection of the siRNA into HeLa and HT29 cells resulted in a 56 +/- 3.6% decrease in dUTPase activity, while transfection of SW620 cells resulted in a 27 +/- 6% decrease in dUTPase activity when compared to non-treated controls.

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...
