Fig. 4. SGK1 mediates Dex-induced breast cancer metastasis.
A The expression of SGK1 in 4T1 cells after Dex treatment. B The expression of SGK1 in 4T1 tumor tissue. C The SGK1 expression after Dex/Wortmannin treatment. D The influence of SGK1 inhibitor GSK650394 on the migration of 4T1 cells. The scale bar is 25 μm, n = 3 replicates. E Treatment scheme. F Tumor growth. (n = 8 mice per group). G The number of metastases on lung surface (n = 8 mice per group). H, I The effect of GSK650394 on experimental lung metastasis model. H Representative image of bioluminescence and statistics were shown (n = 3 mice per group). I The number of metastases on lung surface (n = 5 mice per group). J, K 4T1 cells were treated with Dex/ GSK650394 in vitro for 48 h before inoculation via intravenous injection. J Representative image of bioluminescence and statistics were shown (n = 3 mice per group). K The number of metastases on lung surface (n = 5 mice per group). Mean ± SEM is shown. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001.
