Figure 2. The relationship between TNF-α expression and prognosis and the correlation between TNF-α, MEG8 and miR-454-3p. The correlation between MEG8 and miR-454-3p (A), miR-454-3p and TNF-α (B), MEG8 and TNF-α (C) in PAs was analyzed according to RT-qPCR results. The correlation between MEG8 and miR-454-3p (D), miR-454-3p and TNF-α (E), MEG8 and TNF-α (F) in BIPAs was analyzed according to RT-qPCR results.
