Abstract

Gene silencing using small interfering RNA (siRNA) may be useful for functional analyses of unidentified genes expressed during cell differentiation. The present study was performed to evaluate RNA interference (RNAi) in porcine granulosa cells stimulated with bovine FSH, by using two fluorescence reporter genes: a plasmid encoding green fluorescent protein (GFP) and a plasmid encoding red fluorescent protein (RFP). The siRNA targeting GFP mRNA sequence (GFP-siRNA) with both plasmids was introduced into cultured cells by lipofection. GFP- and RFP-expressing cells were observed under fluorescence microscopy and analyzed by flow cytometry. Strong fluorescence was observed after introduction of both plasmids into cells. The intensity of green fluorescence generated by GFP was greatly suppressed by introduction of GFP-siRNA, showing an approximate 70% decrease in the ratio of green to red fluorescence. Consequently, we concluded that gene silencing by siRNA can be used to analyze the functions of genes of interest during differentiation of porcine granulosa cells.
