Fig. 3From: Enhanced expression of long non-coding RNA NEAT1 is associated with the progression of gastric adenocarcinomasKnockdown of NEAT1 lncRNA impairs growth of GAC cells in vitro. a Expression levels of NEAT1 lncRNA were examined by real-time PCR. b The expressions of NEAT1 mRNA in MGC803 cells transfected with pcDNA3-NEAT1 and control vector detected by RT-qPCR. c After treatment of lentiviruses expressing NEAT1 shRNA and control shRNAs, the expression levels of NEAT1 lncRNA were examined by real-time PCR. The relative expression of NEAT1 lncRNA (as the ratio of NEAT1 lncRNA to β-actin mRNA) is illustrated as a ratio to control (cells transfected with control shRNA). d WST-1 (Roche) assay measuring the activity of mitochondrial dehydrogenases was performed following the manufacturer’s instruction at 0-, 1-, 2-, 3-, and 4-day time points. Error bars represent the standard deviation of the mean. e Cell migration was determined using a transwell assay as described in the “Methods” section. Microscopic image of migrated MKN45 and AGS cells, cells transfected with nonsense strand or NEAT1 shRNA, respectively. Original magnification 200×. The diagrams of migrating cells from the different transfectants are also shown, which come from more than three independent experimentsBack to article page
