Potential role of long noncoding RNA RP5-881L22.5 as a novel biomarker and therapeutic target of colorectal cancer

Figure 5 Results of quantitative reverse transcription PCR for clinical specimens and cellular experiments. A: Expression level of RP5-881L22.5 in tumor tissues and normal tissues among 4 patients’ surgical samples. Red referred to tumor tissues, and blue referred to adjacent normal tissues; B: The apoptosis ratio difference between siRNA + negative control (NC) group and siRNA + RP5-881L22.5; C: Representative image of the siRNA + NC by flow cytometry; D: Representative image of the siRNA+RP5-881L22.5 by flow cytometry; E: Effect of knockdown of RP5-881L22.5 on the transwell invasion assay of colorectal cancer cells. Scale bars: 50 μm. The magnification is 100 times the original size. Left: Representative image of the siRNA + NC; Right: Representative image of the siRNA + RP5-881L22.5.
