Fig 4. RIG-I is involved in regulating the DNA-induced STING degradation.
(A) Western blotting analysis of RIG-I expression after MRC-5 cells were transfected with pcDNA3.1. (B) Time course assessment of RIG-I mRNA after MRC-5 cells were transfected with pcDNA3.1 (0.05μg) for the indicated time points. (C-G) Western blotting shows a reverse correlation between STING and RIG-I under different conditions: dose (C), time (D, E), DNA types (F), and Bortezomib treatment (G). (H) Silencing RIG-I partially reverses the STING degradation. (I) qRT-PCR assessment of RIG-I expression after STING knockdown in MRC-5 cells. Asterisk (*), P <0.05.
