Abstract:
Silencing of gene expression by siRNA (small interfering RNA) is a powerful approach used to study the genetic analysis and functional roles of mammalian genes. There is at present no report about the effects of mammalian two-hybrid system plasmids delivery of sense and antisense strands. The leishmania pteridine reductase 1 (PTR1) gene was cloned as sense and antisense strands into mammalian two hybrid system plasmids. The constructs were transfected into human blood macrophages on the basis of eight experimental groups. (Antisense strand ± LPS, sense strand ± LPS, dsRNA ± LPS, negative control ± LPS). After 24 hours, cytokines production was assessed with ELISA.
Transfection of sense and antisense strand RNA into monocyte-derived macrophages (MDM) was confirmed by RT-PCR. Single strands RNA expressed IL-8, IL-12, IL-1β inflammatory cytokines and dsRNA induced IL-8, IL-12 and TNF-α production in MDM. In contrast, random uptake from a mixture of two plasmids was downregulated IL-8, IL-12, IFN-γ cytokines, with a significant difference of p
