Silencing of lncRNA MIAT alleviates LPS-induced pneumonia via regulating miR-147a/NKAP/NF-κB axis


Figure 6. Inhibition of MIAT alleviates LPS-induced inflammation and injury via miR-147a/NKAP axis in TC-1 cells. Si-MIAT was transfected into TC-1 cells with AMO-147a or NKAP. (A) The transfection efficiency was detected using qRT-PCR. (B) MTT assay for cell viability of TC-1 (C) Apoptosis cell numbers were tested by TUNLE staining. Scale bar, 100 μm. (D) Western blot for cleaved-caspase-3, Bax, Bcl2 in TC-1 cells. (E) Flow cytometry assay used to detect early and late apoptosis cell numbers. (F) qRT-PCR analysis for IL 1β, IL 6 and TNFα expression. (G) Western blot for TNFα and IL 6 expression. (H) Western blot for IκBα and p65. Data are mean ± SD; *P < 0.05. Data are mean ± SD; *P < 0.05 vs LPS+si-Scramble, #P< 0.05 vs LPS+si-MIAT. All experiments were repeated three times.
