FLOT1 depletion boosted DNA damage activated STING signaling pathway. (a) Western blotting analysis of γH2A× at the indicated time points in A549 Plvx-FLOT1 and Plvx-Control group cells. (b) Western blotting analysis of γH2A× at the indicated time points in A549 cell and A549/X sh-FLOT1 and sh-Control group cells after 6 Gy radiation. (c) Western blotting analysis of FLOT1, STING, Phospho-STING, TBK1, and Phospho-TBK1 in A549 and H520 cells after 6 Gy radiation. (d) Western blotting analysis of STING, Phospho-STING, TBK1, and Phospho-TBK1 in A549 Plvx-FLOT1 and Plvx-Control groups after 6 Gy radiation. (e) Western blotting analysis of FLOT1, STING, Phospho-STING, TBK1, and Phospho-TBK1 in A549/X sh-FLOT1 and sh-Control groups after 6 Gy radiation. (f) The mRNA expression of CCL5, CXCL10, and IFNβ wasdetected by Qrt-PCR in A549/X cells with or without FLOT1 depletion after radiation. Each experiment was performed in triplicate, and the values were presented as the mean ± SD. *p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001.
