Fig. 6

a MTT assay of HCT116 colon cancer cells expressing an empty vector (−) or a vector containing myc-tagged PRMT5 (+) in SCR (−) or NAA40-KD (+) conditions. Error bars represent the mean ± s.d of three biological replicates. Unpaired two-tailed Student’s t-test was used (**p < 0.01). Western blot analysis (right panel) was performed to detect ectopic expression of tagged PRMT5 using an antibody against myc. β-actin was used as a loading control. The values below the blot were determined by densitometry analysis. b Meta-analysis of PRMT5 expression levels extracted from the TCGA data portal in 647 colorectal cancer (CRC) and 51 normal patient samples. The Mann–Whitney test was used for the statistical analysis (***p < 0.001). c, d Scatter plots illustrating the correlation between the expression of NAA40 and PRMT5 (c) or between NAA40 and PRMT7 (d) in 647 CRC patient samples extracted from the TCGA database. The red line indicates the linear regression slope. Statistical analysis was performed using Pearson’s rank correlation coefficient (r)
