Effect of CDDP on lung cancer cells. a Western blot analysis of PD-L1 (50 kDa) expression in NCI-H1299 cells induced by CDDP at different concentrations for 48 h. b Cellular uptake of 68Ga-NOTA-Nb109 in NCI-H1299 and CDDP-treated NCI-H1299 cells. c Viability of different lung cancer cells after treatment with various concentrations of CDDP for 48 h. d IC50 values of CDDP against different lung cancer cells obtained using GraphPad Prism 5.0. All data were expressed as mean ± SD (n = 3). ***P < 0.001
