(A and B) Transfection efficiency of negative control FAM-siRNAs in AGS cells. (A) Observation under a regular microscope. (B) Observation of the same field of view using a fluorescence microscope. (A and B: × 200 magnification). (C and D) The effect of different siRNAs on the expression of Lgr5 mRNA and protein. Confluent gastric cancer AGS cells were seeded into 6-well plates, and transfected with different siRNAs (siRNA-Lgr5-409, siRNA-Lgr5-1555, and siRNA-Lgr5-2664) or scramble siRNA (negative control). The untransfected cells served as a blank control. Leucine-rich repeat-containing G-protein-coupled receptor 5 mRNA and protein levels were determined by qPCR and western blotting. Transfection of these Lgr5 siRNAs resulted in a significant decrease in Lgr5 mRNA and protein expression. The Lgr5-homo-2664 exerted the greatest effects in suppressing Lgr5 expression. Triplicate experiments were performed with almost identical results. Expression levels of Lgr5 mRNA are presented as mean±s.d.
