a Immunoblot of GTSE1 expression in AZ521 cells. p: parental cell lines, con: scrambled controls, kd: knockdown variants of GTSE1. At least two independent experiments were preformed for each cell line. b MTS assay to determine IC50 of cisplatin (CIS) in AZ521-cont and its GTSE1 knockdown variant cell line AZ521-kd. Values represent average of two independent experiments and error bars denote standard deviations
