CircNSUN2 promotes metastasis of CRC. a, b Decreased (a) or increased (b) tumor metastasis formed in the livers of mice through the inferior hemispleen implantation of circNSUN2-konckdown (a) or circNSUN2-overexpression (b) TC71 PDX cells. Top, left, representative bioluminescent images of livers for each experimental group at 8 weeks. Top, right, statistical analysis of bioluminescent tracking plots. Bottom, left, representative liver. Bottom, right, the number of metastatic nodules formed in the lungs of mice for each group (n = 6 mice / group). Data represent mean ± S.D.; dot plot reflects data points from independent experiment. The P values were determined by a two-tailed unpaired Student’s t test. c, d Decreased (c) or increased (d) tumor metastasis formed in the lungs of mice through vein tail injection of circNSUN2-konckdown (c) or circNSUN2-overexpression (d) PDX cells. Top, left, representative bioluminescent images of lungs for each experimental group during 6 weeks. Top, right, statistical analysis of bioluminescent tracking plots. Bottom, left, representative lung and representative HE staining of lung metastatic lesions, Original magnification, ×4, scale bar, 100 µm. Bottom, right, the number of metastatic nodules formed in the lungs of mice for each group (n = 6 mice/group). Data represent mean ± S.D.; dot plot reflects data points from independent experiment. The P values were determined by a two-tailed unpaired Student’s t test. Source data are provided as a Source Data file
