title: Lentiviral vector-mediated siRNA knockdown and concurrent rescue of Murine CIN85.
abstract: RNA interference (RNAi), an evolutionarily conserved process of gene silencing, is now a common tool in gene functional studies. However, potential "off-target effects" is one of major concerns in RNAi experiment associated with false positive results. Apart from continuing improvement in small interfering RNA (siRNA) designs, there is no method available to prevent the generation of "off-target effects" resulted from possible identity between siRNA and abundant cellular mRNA transcripts. In the present study, we have developed a lentiviral vector-mediated system that allows efficient siRNA silencing and concurrent rescue of targeted genes. While this approach does not eliminate potential "off-target effects," concurrent rescue of a target gene allows a definite judgment with regard to a phenotype change, either from expected siRNA silencing or "off-target effects." The system has been validated with murine CIN85 gene and may be generally applicable in molecular studies from broad fields.
