Extramural venous invasion in gastric cancer: 9.4T magnetic resonance imaging assessment and circular RNA functional analysis

Figure 2 The expression of hsa_circ_0097977 in gastric cancer cell lines. A: The expression of hsa_circ_0097977 in normal gastric mucosal epithelial cells and six human gastric cancer cell lines. The relative value (RV) of expression of each circRNA was determined by the 2-Δct method using glyceraldehyde-3-phosphate dehydrogenase as a normalizer. The expression value of each circRNA was scaled to a reasonable range with the following equation: Log2 (RV × 10000 + 1); B: The relative expression level of hsa_circ_0097977 in cells after transfection. The relative expression level was calculated as 2^-∆∆Ct × 100%. KD: Knockdown; NC: Negative control.
