Fig. 1From: Comparative transcriptome analysis uncovers roles of hydrogen sulfide for alleviating cadmium toxicity in Tetrahymena thermophilaProliferation of T. thermophila under Cd and H2S treatments. a IC50 value of Cd. The inhibition ratio of cell proliferation in different concentrations of Cd (0.5, 1, 2, 4, 8, 16, 32, 64, 128, and 256 μM). The IC50 of Cd was calculated by GraphPad Prism 5. b Cell proliferation in different concentrations of NaHS (50, 70, 100, 200, and 400 μM). c Cell proliferation under 70 μM NaHS (S), 30 μM Cd (C), and 30 μM Cd+ 70 μM NaHS (CS) treatmentsBack to article page
