Effects of stable overexpression of NOP53 in three cell lines (TPC1, FTC133, BCPAP): (a) Validation of stable overexpression of wild type (WT) and D31H mutant NOP53 in three cell lines by qPCR; (b) Validation by Western blot. The lower band corresponds to the endogenous protein expression, whereas the upper band represents the exogenous overexpressed protein. The total protein lysates used were 25 µg for TPC1 cell line, and 30 µg for FTC133 and BCPAP cell lines. GAPDH and β-actin were used as an internal and loading control for qPCR and Western blot, respectively; (c) Overexpression of WT and D31H mutant NOP53 significantly increased the cell proliferation in thyroid cancer cell lines compared to the vector control; (d) Overexpression of WT and D31H mutant NOP53 significantly increased the cell clonogenicity in thyroid cancer cell lines compared to the vector control. * indicates adjusted p value < 0.05 compared to control. ** indicate adjusted p value < 0.01 compared to control. Error bars indicate standard deviation.
